Technical Field

Background
Petroleum and natural gas are important strategic resources of the country and are important life lines for national economic development. The fault is an important channel for oil and gas migration, and the opening degree and the closing degree of the fault have important influence on the oil and gas migration. The larger the fault opening degree is, the stronger the fault conducting capacity is, and oil and gas can be effectively transported along the fault; on the contrary, the larger the fault closure degree is, the poorer the fault conduction capability is, and the poorer the migration effectiveness of oil and gas along the fault is. Because the opening degree and the closing degree of the fault directly influence the oil and gas migration efficiency, and the opening degree and the closing degree of the fault can be described by the closure of the fault.

Because the opening degree and the closing degree of the fault directly influence the oil and gas migration efficiency, and the opening degree and the closing degree of the fault can be described by the closure of the fault. Therefore, in order to determine the migration capability of a fault to hydrocarbons, it is often necessary to determine the seal of the fault.

and determining the position corresponding to the minimum vertical fault pressure value in the pressure change curve as the position with the worst closure in the fault.
All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 2 is a flowchart of a method for determining fault blocking according to an embodiment of the present disclosure, and referring to fig. 2, the method includes the following steps.
Step 201: the method comprises the steps that a terminal obtains at least one fault inclination angle and at least one static rock pressure value of a fault, and the at least one fault inclination angle corresponds to the at least one static rock pressure value one to one.
Because the fault opening and closing degree, namely the closure, is usually related to the static rock pressure value of the fault, the fault inclination of the fault also affects the closure of the fault, and the closures of different positions of the fault are different, the terminal can acquire at least one fault inclination and at least one static rock pressure value of the fault.
The operation of the terminal for acquiring at least one fault dip angle of the fault can be as follows: acquiring the fault trend of the fault; acquiring at least one seismic profile corresponding to the fault according to the fault trend of the fault, wherein the seismic survey line of the at least one seismic profile is vertical to the fault trend; drawing a fault plane diagram of the fault according to the transverse-phase-axis fault characteristics of the earthquake described in the at least one seismic section diagram and the at least one seismic section diagram, wherein the fault plane diagram comprises fault lines of the fault; and determining an included angle between a fault line of any seismic section in the at least one seismic section and the horizontal line as a fault dip angle of the seismic section corresponding to the fault.
It should be noted that the terminal may receive the fault trend of the fault input by the staff through the designated operation, or the terminal may send an information acquisition request to a third-party device such as a server, where the information acquisition request carries a fault identifier, and after receiving the information acquisition request, the third-party device may return fault information to the terminal, where the fault information includes the fault trend. The designated operation may be an input operation, a click operation, a voice operation, a slide operation, or the like, and the fault direction may be a north-south direction, an east-west direction, or the like.
In addition, the operation of the terminal for acquiring at least one seismic profile corresponding to the layer according to the fault trend of the fault can be as follows: dividing the seismic section initial image corresponding to the fault at equal distance according to the fault trend of the fault to obtain at least one seismic section image, and referring to fig. 3; or dividing the seismic section initial image randomly according to the fault trend of the fault to obtain the at least one seismic section image.
It should be noted that, when the terminal divides the seismic section initial diagram corresponding to the fault at equal distances, the equal distances may be determined according to the length of the fault center line along the fault trend in the seismic section initial diagram, and the preset number may be set in advance, for example, the preset number may be 5, 4, 3, and the like. For example, if the length of the fault center line is 1 kilometer and the preset number is 5, the division distance is 200 meters, and the seismic section initial graph corresponding to the fault is divided according to the equal distance, that is, the seismic section initial graph is divided according to the division distance of 200 meters.
Since the earthquake causes a fault, the terminal can draw a fault plane map of the fault through a mapping application according to the transverse-phase axis fault characteristic of the earthquake described in the at least one seismic section map and the at least one seismic section map. For example, the terminal may plot a fault plane view of the fault as shown in FIG. 4 according to the transverse-facies fault characteristics of the earthquake as described in at least one seismic profile shown in FIG. 3.
It should be noted that the included angle between the fault line and the horizontal line of any seismic profile may be obtained by a worker manually measuring at least one profile, or may be obtained by a terminal through an application of angle measurement.
In addition, the seismic section initial image can be uploaded to a terminal through a designated operation by a worker, and can also be obtained from fault information for the terminal. That is, the fault information may include an initial seismic profile, and the terminal acquires the initial seismic profile from the fault information after acquiring the fault information.
Further, after the terminal acquires the at least one seismic section, in order to acquire an accurate fault dip angle from the at least one seismic section in the way, the ratio of the longitudinal depth to the transverse length of each seismic section in the at least one seismic section can be adjusted to 1: 1.
furthermore, the operation of the terminal acquiring at least one static rock pressure value of the fault may be: receiving at least one static rock pressure value input by a user through a specified operation; or, acquiring at least one reference depth of the fault and the overburden average density; at least one lithostatic pressure value is determined based on the at least one reference depth and the overburden average density.
And the terminal can determine a lithostatic pressure value corresponding to any one of the at least one reference depth through the following second formula based on the any one of the at least one reference depth and the average density of the overburden.
P＝hgρ (1)
In the second formula (1), h is any reference depth of a fault and is expressed in kilometers (km), P is a lithostatic pressure value and is expressed in megapascals (MPa), and ρ is an average density of an overburden and is expressed in grams per cubic centimeter (g/cm)3) G is the acceleration of gravity, typically 9.8 km/h.
In addition, the terminal may obtain the at least one fault dip and the at least one lithostatic pressure value through the above method, and may also obtain the fault information through other methods, for example, the terminal may obtain the fault information from a third-party device such as a server, and then the fault information may further include the at least one fault dip and the at least one lithostatic pressure value of the fault.
Step 202: and the terminal determines at least one vertical fault pressure value corresponding to the fault based on the at least one fault inclination angle and the at least one static rock pressure value.
Since the closing degree of the fault cannot be accurately described only through the static rock pressure value, in order to accurately describe the closing degree of the fault, the terminal can also determine at least one vertical fault pressure value corresponding to the fault.
The terminal can determine a vertical fault pressure value corresponding to any fault dip angle through the following first formula based on any fault dip angle in at least one fault dip angle and a static rock pressure value corresponding to any fault dip angle.
Ph＝P*cosα (2)
In the first formula (2), P ishThe pressure value of the vertical fault is α, which is any fault dip angle, and P is the static rock pressure value corresponding to any fault dip angle.
Step 203: the terminal determines the sealing performance of the fault based on the at least one vertical fault pressure value.
It should be noted that, when the terminal determines the sealing performance of the fault based on the at least one vertical fault pressure value, the at least one vertical fault pressure value is a vertical fault pressure value for the cause at the same reference depth.
The terminal can determine the sealing performance of the fault based on at least one vertical fault pressure value, and the operation of determining the sealing performance of the fault can comprise the following two modes.
In the first mode, the terminal determines the position corresponding to the maximum vertical fault pressure value in at least one vertical fault pressure value as the position with the optimal closure in the fault; and determining the position corresponding to the minimum vertical fault pressure value in the at least one vertical fault pressure value as the position with the worst closure in the fault.
It should be noted that the larger the pressure value of the vertical fault is, the larger the closing degree of the fault at the position is, and the position with the large closing degree of the fault is the oil and gas formation favorable area. Conversely, the smaller the pressure value of the vertical fault is, the smaller the closing degree of the fault at the position is, and the larger the opening degree is, the position with the large opening degree of the fault is the position with high oil and gas migration efficiency.
In the second mode, the terminal draws a pressure change curve according to at least one vertical fault pressure value and the fault trend of the fault; determining the position corresponding to the maximum vertical fault pressure value in the pressure change curve as the position with the optimal closure in the fault; and determining the position corresponding to the minimum vertical fault pressure value in the pressure change curve as the position with the worst closure in the fault.
For example, when the terminal determines three seismic sections, and 3 sections are a section a, a section B, and a section C as shown in fig. 3 and 4, the terminal may determine vertical fault pressure values corresponding to the 3 sections, respectively, and draw a pressure change curve as shown in fig. 5 according to the 3 vertical fault pressure values and fault trends of the faults.
Step 204: and the terminal prompts the sealing property of the fault through prompt information.
