Description

Method, device and storage medium for determining invasion position of diabase in oil reservoir

Technical Field

The invention relates to the technical field of oil field geophysical prospecting, in particular to a method, a device and a storage medium for determining an invasion position of a diabase body in an oil reservoir.

Background

Diabase is a basic shallow invasion rock, often invaded in sand mudstone, whose main mineral components are pyroxene and basic plagioclase. Because diabase is developed more and has more perfect fracture-cavity units and larger porosity, and is a good reservoir body of oil and gas, the invasion position of diabase in an oil reservoir needs to be determined in the geological exploration process so as to be used as a basis for searching the oil and gas reservoir in the oil reservoir.

In the related art, since the propagation velocity of the seismic wave in diabase is higher than the propagation velocity in oil-, gas-or water-free sand mudstone at the top-bottom interface of diabase, the amplitude of the seismic wave in diabase is larger than the amplitude of the seismic wave in sand mudstone, based on this, when determining the invasion position of diabase in an oil reservoir by using seismic data, a technician may generally find an interval in which the amplitude of the seismic wave is larger than the amplitude of the seismic wave at an adjacent position in an oil reservoir seismic amplitude profile display graph drawn by seismic amplitude, determine the interval as a diabase interval, and determine the position of the diabase interval as the invasion position of diabase.

However, when the sandstone at the top-bottom interface of diabase is oil, gas or water, since the propagation velocity of the seismic wave in the oil, gas or water-containing sandstone is greater than that of the oil, gas or water-free sandstone, the amplitude of the seismic wave in the oil, gas or water-containing sandstone is also increased, so that the difference between the amplitudes of the seismic wave in the diabase and the oil, gas or water-containing sandstone is reduced, the intrusion position of the diabase cannot be accurately determined, and the determination result error is large.

All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present invention, which is not described in detail herein.

Fig. 2 is a flowchart of another method for determining an invasion position of diabase in an oil reservoir according to an embodiment of the present invention, where the method may be applied to a terminal, which may be a mobile phone, a tablet computer, a computer, or the like. Referring to fig. 2, the method comprises the steps of:

step 201: and acquiring the amplitude data of each seismic channel in a plurality of seismic channels in the target oil reservoir.

The multiple seismic channels are obtained by detecting seismic waves propagated in the target oil reservoir at multiple positions of the target oil reservoir, that is, the multiple seismic channels are seismic wave data detected at different positions of the target oil reservoir. Furthermore, since seismic waves are typically periodically propagated in the target reservoir, each seismic trace includes a plurality of seismic wave periods, and the amplitude data of each seismic trace is composed of the amplitude data of the plurality of seismic wave periods.

In practical application, the amplitude data of each seismic channel in the multiple seismic channels can be obtained by user input, can also be obtained by sending of other equipment, and can also be obtained by time domain seismic data volume analysis of a target oil reservoir. For example, a time domain seismic data volume of a target reservoir is obtained, where the time domain seismic data volume includes original seismic wave amplitude data of each of a plurality of seismic traces for describing a geological structure of the target reservoir and time data when the original seismic wave amplitude data is received, then the time domain seismic data volume is converted into a depth domain seismic data volume through a time domain-depth domain seismic data volume conversion formula, where the depth domain seismic data volume includes seismic wave amplitude data of each of the plurality of seismic traces for characterizing the target reservoir and formation depth data corresponding to each of the original seismic wave amplitude data, and finally, the amplitude data of each of the plurality of seismic traces in the obtained depth domain seismic data volume is determined as the amplitude data of each of the plurality of seismic traces in the target reservoir.

It should be noted that the time domain-depth domain seismic data volume conversion formula required for converting the time domain seismic data volume into the depth domain seismic data volume is common knowledge in the art, and the specific form of the time domain-depth domain seismic data volume conversion formula may be selected by a skilled person according to the actual characteristics of the target reservoir and the processing capability of the terminal, which is not specifically limited in this embodiment of the present invention.

In addition, the reservoir depth in the embodiment of the present invention refers to the shortest distance from the position of any point in the target reservoir to the top surface of the target reservoir, which is measured by using the top surface of the target reservoir as a reference surface. Since the distance is positive, the reservoir depth is also positive.

Step 202: and determining an amplitude ratio value set of each seismic channel according to the amplitude data of each seismic channel in the plurality of seismic channels.

The amplitude ratio value set of each seismic channel comprises the amplitude ratio values of a plurality of seismic wave periods of each seismic channel, and the amplitude ratio value of each seismic wave period refers to the ratio of the amplitude value of the peak position to the amplitude value of the trough position of each seismic wave period.

Specifically, after obtaining the amplitude data of each of the plurality of seismic channels in the target oil reservoir, the terminal may analyze the amplitude data of each of the plurality of seismic channels in the target oil reservoir to obtain a plurality of seismic wave periods of each seismic channel, an amplitude value at a peak position and an amplitude value at a trough position in each of the plurality of seismic wave periods, and an oil reservoir depth corresponding to positions of three 0 phases arranged in order from the top to the bottom of the oil reservoir in each seismic wave period.

After the amplitude value at the peak position and the amplitude value at the trough position in each seismic wave period in the multiple seismic wave periods of each seismic channel are obtained, determining the ratio of the amplitude value at the peak position and the amplitude value at the trough position in each seismic wave period in the multiple seismic wave periods of each seismic channel as the amplitude ratio of the seismic wave period, and determining the amplitude ratios of the multiple seismic wave periods of each seismic channel as the amplitude ratio set of the seismic channel.

In one possible embodiment, Table 1 shows amplitude data on a seismic trace of a target reservoir, where the first column shows the seismic wave period, the second column shows the amplitude values at the peak position, the third column shows the amplitude values at the trough position, and the fourth column shows the amplitude ratio.

TABLE 1

As can be seen from table 1, three seismic wave periods exist on one seismic trace of the target reservoir, where the amplitude ratio of the first period is 2.41, the amplitude ratio of the second period is 1.06, and the amplitude ratio of the third period is 2.39, and then the set {2.41,1.06,2.39} of the amplitude ratios of the three periods is determined as the amplitude ratio set of the seismic trace.

It should be noted that the amplitude data on the seismic trace of the target reservoir shown in table 1 above are all exemplary data given in the embodiment of the present invention, and do not constitute a specific limitation on the amplitude data on the seismic trace of the target reservoir.

Step 203: and determining the invasion position of diabase in the target oil reservoir according to the amplitude data and the amplitude ratio value set of each seismic channel in the plurality of seismic channels.

Specifically, the invasion position of diabase in the target oil reservoir can be determined through the following steps 2031 to 2033 according to the amplitude ratio value set of each seismic channel in the plurality of seismic channels.

Step 2031: and determining a positive polarity earthquake display section of the target oil deposit according to the amplitude data of each of the plurality of seismic channels.

Specifically, referring to fig. 3, when determining a positive polarity seismic display section of the target oil reservoir, a positive reflection coefficient interface and a negative reflection coefficient interface may be determined, where the positive reflection coefficient interface is a surface composed of a point at a position corresponding to a maximum amplitude in each of the plurality of seismic wave cycles, the negative reflection coefficient interface is a surface composed of a point at a position corresponding to a minimum amplitude in each of the plurality of seismic wave cycles, the positive reflection coefficient interface in the amplitude data of each of the plurality of seismic traces may be mapped to a peak of the positive polarity seismic display section, and the negative reflection coefficient interface is mapped to a trough of the positive polarity seismic display section, so as to obtain the positive polarity seismic display section of the target oil reservoir. In addition, in the positive polarity earthquake display section, the wave crest in each seismic channel in the plurality of seismic channels can be marked to be black, so that a plurality of coaxial continuous wave crests on the same axis in the positive polarity earthquake display section of the target oil deposit can be determined according to the black mark of the wave crest in each seismic channel in the plurality of seismic channels, and the lithologic development rule of the target oil deposit can be observed more clearly and more visually.

Step 2032: and determining the top boundary position and the bottom boundary position of the invasion position of the diabase in the target oil deposit according to the positive earthquake display section and the amplitude ratio value set of each seismic channel in the plurality of seismic channels.

Before determining the top boundary position and the bottom boundary position of the invasion position of diabase in the target oil reservoir according to the positive seismic display section and the amplitude ratio value set of each seismic channel in the plurality of seismic channels, the top boundary position period of each seismic channel can be determined according to the amplitude ratio value set of each seismic channel in the plurality of seismic channels, and the top boundary position and the bottom boundary position of the invasion position of diabase in the target oil reservoir can be determined according to the positive seismic display section and the top boundary position period of each seismic channel.

Optionally, the top boundary position period of each seismic trace may be determined according to the following steps:

(1) and for each seismic channel in the plurality of seismic channels, if the absolute value of the difference value between the amplitude ratio of the first seismic wave period starting from the top of the target oil reservoir in each seismic channel and 1 is smaller than a first threshold value, determining the first seismic wave period as the top boundary position period of each seismic channel.

The first preset threshold may be preset, specifically may be set by a technician according to actual conditions of different oil reservoirs, or may be set by a terminal default, which is not limited in the embodiment of the present invention. For example, the first preset threshold may be set to 0.2.

In a possible embodiment, assuming that the first preset threshold is 0.2, if the amplitude ratio of the first seismic wave period starting from the top of the target oil reservoir in each seismic trace is 1.1, and the absolute value of the difference between the amplitude ratio of the seismic wave period and 1 is 0.1, at this time, the absolute value of the difference between the amplitude ratio of the seismic wave period and 1 is less than the first threshold 0.2, the first seismic wave period starting from the top of the target oil reservoir in each seismic trace may be determined as the top boundary position period of each seismic trace; if the amplitude ratio of the first seismic wave period starting from the top of the target oil reservoir in each seismic channel is 2.5, the absolute value of the difference between the amplitude ratio of the seismic wave period and 1 is 1.5, at this time, the absolute value of the difference between the amplitude ratio of the seismic wave period and 1 is greater than a first threshold value 0.2, and the first seismic wave period starting from the top of the target oil reservoir in each seismic channel is not the top boundary position period of each seismic channel. The first threshold and the amplitude ratio are not particularly limited in the embodiments of the present invention.

(2) And if the amplitude ratio of the k +1 th seismic wave period starting from the top of the target oil reservoir in each seismic channel is smaller than the amplitude ratio of the k +1 th seismic wave period, and the absolute value of the difference between the amplitude ratio of the k +1 th seismic wave period and 1 is smaller than a first threshold, determining the k +1 th seismic wave period as the top boundary position period of each seismic channel, wherein k is a positive integer.

It should be noted that, in the target oil reservoir, the propagation speed of the seismic wave in the diabase is higher than the propagation speed of the seismic wave in the sand mudstone, and therefore, the amplitude value at the peak position and the amplitude value at the trough position in the seismic wave period of the diabase are both greater than the amplitude value at the peak position and the amplitude value at the trough position in the seismic wave period of the sand mudstone, and since the amplitude value at the peak position and the amplitude value at the trough position in the seismic wave period of the diabase are relatively stable, the amplitude ratio of the diabase is close to 1, and due to the layering effect of the sand mudstone, the amplitude ratio of the sand mudstone at the peak position and the amplitude value at the trough position in the seismic wave period of the sand mudstone is greater than 1, and therefore, it is possible to determine that the amplitude ratio of the k +1 seismic wave periods from the top of the target oil reservoir in each seismic channel is greater than 1 And determining the top boundary position period of each seismic channel by using the amplitude ratio smaller than the kth seismic wave period and the absolute value of the difference between the amplitude ratio of the kth +1 seismic wave period and 1 smaller than a first threshold.

In addition, when the amplitude ratio of at least two seismic wave periods existing in one seismic channel meets the judgment condition, the top boundary position period of at least two diabase existing in one seismic channel can be determined.

In one possible embodiment, where table 2 shows amplitude ratios of multiple seismic wave cycles in a seismic trace in a target reservoir, the first threshold may be 0.2. Where the first column shows the number of seismic wave cycles and the second column shows the amplitude ratio.

TABLE 2

Numbering of seismic wave periods	Amplitude ratio
		1	2.41
2	2.2
		3	1.52
4	1.06
		5	1.22
6	3.29
		7	3.53

As can be seen from Table 2, the amplitude ratio of the 4 th seismic wave period from the top of the target reservoir is smaller than the amplitude ratio of the 3 rd seismic wave period, and the difference between the amplitude ratio of the 4 th seismic wave period and 1 is smaller than 0.2, then the 4 th seismic wave period can be determined as the top boundary position period of the seismic trace.

It should be noted that the amplitude ratio of a plurality of seismic wave periods on a seismic trace of a target reservoir and the first threshold shown in table 2 are exemplary data given in the embodiment of the present invention, and do not constitute a specific limitation on the amplitude ratio of a plurality of seismic wave periods and the first threshold on a seismic trace of a target reservoir.

Step 2033: and determining the top boundary position and the bottom boundary position of the invasion position of the diabase in the target oil reservoir according to the top boundary position periods of the plurality of seismic channels.

When determining the top boundary position and the bottom boundary position of the invasion position of diabase in the target oil reservoir, the top boundary position of the invasion position of diabase in the target oil reservoir may be determined, and then the bottom boundary position of the invasion position of diabase in the target oil reservoir may be determined according to the top boundary position of the invasion position of diabase in the target oil reservoir.

Alternatively, the top boundary position of the invasion position of diabase in the target reservoir may be determined according to the following steps:

(1) in the positive polarity earthquake display section, the peak positions of the top boundary position cycles of a plurality of earthquake channels are marked so as to obtain a plurality of top boundary position points of the invasion position of diabase.

(2) And determining the top boundary position of the invasion position of the diabase in the target oil reservoir according to the plurality of top boundary position points of the invasion position of the diabase.

It should be noted that, because the positive polarity seismic display section has the peak corresponding to the positive reflection coefficient interface, that is, the peak position in the top boundary position period in the positive polarity seismic display section can be determined as the top boundary position of the invasion position of diabase, after the top boundary position period of each seismic channel is determined, the position of the peak in the top boundary position period of each seismic channel can be marked, so as to identify the top boundary position point on each seismic channel in the positive polarity seismic display section, and the position corresponding to the top boundary position point on each seismic channel is the top boundary position of the invasion position of diabase on each seismic channel.

After the top boundary position points of the invasion position of the diabase are determined, smoothly connecting the top boundary position points to obtain a connecting line of the top boundary position of the invasion position of the diabase, and determining the top boundary position of the invasion position of the diabase on each seismic channel according to the specific position of the connecting line of the top boundary position of the invasion position of the diabase in the positive polarity seismic display section.

After the top boundary position of the invasion position of the diabase on each seismic channel is determined, the bottom boundary position of the invasion position of the diabase on each seismic channel can be determined according to the top boundary position period in the positive polarity seismic display section. And when the bottom boundary position of the invasion position of the diabase on each seismic channel is determined according to the top boundary position period in the positive polarity seismic display section, the bottom boundary position of the invasion position of the diabase on each seismic channel can be directly determined through the top boundary position period in the positive polarity seismic display section, or a reverse polarity seismic display section can be determined according to the positive polarity seismic display section, and then the bottom boundary position of the invasion position of the diabase on each seismic channel can be determined according to the top boundary position period in the reverse polarity seismic display section.

Optionally, in the positive polarity seismic display section, marking the last 0 phase position of the top boundary position cycle of the multiple seismic channels to obtain multiple bottom boundary position points of the invasion position of the diabase; and determining the bottom boundary position of the invasion position of the diabase in the target oil reservoir according to the plurality of bottom boundary position points of the invasion position of the diabase.

It should be noted that, when diabase develops in the oil reservoir, the bottom boundary position of the invasion position of diabase and the corresponding top boundary position thereof are all in one seismic wave period, that is, the thickness of diabase when invading the oil reservoir is less than one seismic wave period, therefore, after the top boundary position period of a plurality of seismic channels is determined, the last 0 phase position point of the top boundary position period of the plurality of seismic channels can be determined as the bottom boundary position point of the invasion position of diabase of the plurality of seismic channels, the plurality of bottom boundary position points are smoothly connected, that is, the connecting line of the bottom boundary position of the invasion position of diabase can be obtained, and the bottom boundary position of the invasion position of diabase on each seismic channel can be determined according to the specific position of the connecting line of the bottom boundary position of diabase in the positive polarity seismic display section.

Optionally, referring to fig. 4, in order to more clearly and more intuitively show the bottom boundary position of the invasion position of the diabase on each seismic channel, when determining the bottom boundary position of the invasion position of the diabase on each seismic channel, the polarity of the seismic wave period on each seismic channel in the positive polarity seismic display section may be reversed by 180 degrees, so that the peak of the seismic wave period on each seismic channel in the positive polarity seismic display section becomes the trough in the reverse polarity seismic display section, and the trough of the seismic wave period on each seismic channel in the positive polarity seismic display section becomes the peak in the reverse polarity seismic display section

In the reverse polarity seismic display section, although the peak and the trough in the top boundary position period are subjected to polarity conversion by 180 degrees, the relative position of the top boundary position period in the reverse polarity seismic display section is not changed, so that the last 0-phase position point of the top boundary position period of a plurality of seismic channels in the reverse polarity seismic display section can be determined as the bottom boundary position point of the invasion positions of the diabase of the plurality of seismic channels, the bottom boundary position points are smoothly connected, the connecting line of the bottom boundary position of the invasion position of the diabase can be obtained, and the bottom boundary position of the invasion position of the diabase on each seismic channel can be determined according to the specific position of the connecting line of the bottom boundary position of the invasion position of the diabase in the reverse polarity seismic display section. In addition, in order to enable the bottom boundary position of the invasion position of the diabase in the target oil reservoir to be clearer in the reversed polarity earthquake display section, wave crests in all earthquake wave periods in a plurality of earthquake channels in the reversed polarity earthquake display section can be marked to be black, so that the bottom boundary position of the invasion position of the diabase in the target oil reservoir can be observed more clearly and more visually according to the black marks of the wave crests in all earthquake wave periods in the plurality of earthquake channels.

Step 2034: and determining the invasion position of the diabase in the target oil reservoir according to the top boundary position of the invasion position of the diabase in the target oil reservoir and the bottom boundary position of the invasion position of the diabase in the target oil reservoir.

After the top boundary position according to the invasion position of the diabase in the target oil reservoir and the bottom boundary position according to the invasion position of the diabase in the target oil reservoir are determined, the position between the top boundary position of the invasion position of the diabase in the target oil reservoir and the bottom boundary position of the invasion position of the diabase in the target oil reservoir can be determined as the invasion position of the diabase in the target oil reservoir.

Step 204: and determining a target point of a new well to be deployed in the target oil reservoir according to the invasion position of diabase in the target oil reservoir, wherein the target point of the new well to be deployed refers to the position of the new well to be deployed, which needs to be drilled to meet diabase in the drilling process.

Because diabase is developed more and has more perfect fracture-cavity units and porosity is larger, the diabase is a good reservoir body of oil gas and is a geological basis for determining the target point of the new well to be deployed, the target point of the new well to be deployed can be further determined after the invasion position of the diabase in the target oil deposit is determined, and the drilling success rate of the new well to be deployed in the target oil deposit is improved.

When determining a target point of a new well to be deployed in a target oil reservoir, determining the oil-gas-containing position in diabase according to the invasion position of diabase in the target oil reservoir and the amplitude data of each seismic channel in a plurality of seismic channels; and determining a target point of a new well to be deployed in the target oil reservoir according to the oil-gas-containing position in the diabase.

Specifically, because the oil-gas storage probability of the upper layer position in the invasion position of the diabase in the target oil reservoir is greater than that of the lower layer position, after the invasion position of the diabase in the target oil reservoir is determined, the invasion position of the diabase can be further layered according to the amplitude data of each seismic channel in a plurality of seismic channels in the target oil reservoir to obtain the invasion position of the upper layer diabase and the invasion position of the lower layer diabase, wherein the invasion position of the upper layer diabase is the oil-gas position in the diabase, and any position in the invasion position of the upper layer diabase can be determined as a target point of a new well to be deployed in the target oil reservoir.

In a possible embodiment, if 7 drilled positions in a target oil reservoir are assumed to be drilled all at diabase, diabase reservoir yield is high, oil test daily yield is up to 22t/d, and initial daily yield after production is up to 33t/d, therefore, the method provided by the embodiment of the invention can be used for determining the diabase invasion position of the target oil reservoir, and after the diabase invasion position in the target oil reservoir is determined, new wells are drilled in the target oil reservoir, and the drilling result is shown in table 3. Where the first column of table 3 shows the well number, the second column shows the amplitude value at the peak position of the diabase, the third column shows the amplitude value at the trough position of the diabase, the fourth column shows the amplitude ratio, the fifth column shows the target depth, the sixth column shows the actual drilling depth, and the seventh column shows the error rate.

TABLE 3

As can be seen from table 3, after the invasion position of diabase is determined according to the method provided by the embodiment of the present invention, the error rate between the target point of the new well to be deployed and the depth of the target point encountered by the actual drill is further determined to be not greater than 1%, which indicates that the accuracy of determining the target point of the new well to be deployed according to the invasion position of diabase determined by the method provided by the embodiment of the present invention is higher.

It should be noted that, because of the influence of factors such as geological environment and government land use management policy, the well mouth position of the new well to be deployed cannot be directly deployed at the ground position vertically corresponding to the determined target point of the new well to be deployed, so that after the target point of the new well to be deployed in the target oil reservoir is determined, the well bore track of the new well to be deployed in the target oil reservoir can be determined according to the obtained well mouth position and the obtained target point position of the new well to be deployed in the target oil reservoir.

For example, when the method is not limited by geological environment and government land use management policies, the wellhead position of a new well to be deployed in the target oil reservoir can be selected on the ground position vertically corresponding to the target point, and the well track at the moment is a vertical line; when the method is limited by geological environment and government land use management policies, after the wellhead position of the new well to be deployed in the target oil reservoir is determined, the optimal borehole trajectory can be determined according to the wellhead position and the target point of the new well to be deployed in the target oil reservoir, so that the borehole trajectory is scientific and reasonable, and the drilling efficiency is also improved.
