Description

Method and device for measuring oil phase flow, equipment, storage medium and logging instrument

Technical Field

The disclosure relates to the technical field of well logging, in particular to a method, a device and equipment for measuring oil phase flow, a storage medium and a logging instrument.

Background

Most of the old oil field development in China enters the later development stage, the residual difficult-to-recover reserves are mostly concentrated in difficult-to-recover oil reservoirs with complex terrains or compact oil, low permeability and the like, and the development requirements cannot be met by adopting the conventional vertical well technology. The oil drainage area of the horizontal well is hundreds of times of that of the straight well, along with the development of the horizontal well technology, the cost of one horizontal well is only 2 times of that of the straight well, the benefit is 4-5 times of that of the straight well, and the economic benefit is obvious. The development of the highly-deviated well can enable the well mouth to avoid residential areas and complex terrains, and underground reserves can be effectively used. For example, in the old world of the Changyuan in the four factories of oil extraction in Daqing oil field, the development cost cannot be effectively controlled by high-strength water injection and large-scale liquid extraction in the past. At the end of 6 months in 2019, a Daqing oil field oil extraction four-factory is designed to drill 28 highly deviated wells by means of a highly deviated well diving technology, and the accumulated oil production is 14 ten thousand tons. Although the development effect of the horizontal well and the highly deviated well is remarkable, along with the extension of development time, the water content of the highly deviated well after water breakthrough rapidly rises, the oil yield rapidly falls, and the development effect of the highly deviated well is seriously influenced, so that the research on the horizontal well and highly deviated well logging technology has important significance.

At present, a mature production profile logging technology applied to a low-liquid-production horizontal well and a high-gradient well does not exist in China, the domestic horizontal well logging mainly adopts a capacitance type water content meter and a flow-collecting turbine flowmeter to carry out combined logging, but for the low-liquid-production well, the flow velocity of fluid in the well is too low, so that a turbine cannot work normally, the water content measurement result is greatly influenced by a horizontal inclination angle, and the measurement precision of an instrument is greatly reduced. A combined logging instrument for the output profile of a low-fluid horizontal well with a dual working mode (patent number ZL201810182569.2) is specially designed for the flow rate of the low-fluid horizontal well, and can accurately measure the single-phase flow rate of an oil phase, but in a horizontal well with a horizontal inclination angle and a highly-deviated well, the measuring result of the instrument can be influenced by the horizontal inclination angle, so that the measuring precision is reduced.

The angle correction probe array 8 is formed by 7 conductance probes distributed in the side surface of the rotary accumulation cavity 7 in a high-line average distribution mode, and the angle correction probe array 8 and the positive angle oil flow measurement probe array 11 work when the oil flow is measured.

In the embodiment of the disclosure and other possible embodiments, the oil phase accumulation condition in the rotary accumulation cavity 7 is monitored simultaneously through the angle correction probe array 8 and the positive angle oil flow measurement probe array 11, and the oil volume flow at the horizontal inclination angle is corrected to the oil volume flow at the pure horizontal inclination angle through derivation of a geometric formula, so that the influence of the horizontal inclination angle on the oil flow measurement is overcome.

In the embodiment of the present disclosure and other possible embodiments, the working principle of the angle correction probe array 8 and the positive angle oil flow measurement probe array 11 are the same, and they are all composed of seven conductance probes, and the working principle is as follows: the resistivity of the contacted fluid is measured by a conductivity probe, which has a low value of response when submerged in water and a high value of response when submerged in oil. When the oil phase flow enters the rotary accumulation cavity, the conductivity probe begins to be immersed slowly along with the accumulation of the oil phase flow in the rotary accumulation cavity, and the response values of the immersed conductivity probe are high values. Through the design of the circuit system, the response values of the seven conductance probes are summed actually, the distribution intervals of the probes of the angle correction probe array 8 and the positive angle oil flow measurement probe array 11 are the same, and the response values of the circuit system rise by one step respectively every time the probe is immersed in the oil phase along with the immersion of the oil phase, which can be seen in detail in the following fig. 4. Therefore, the distributed conductance probes can be used for acquiring the height of the oil-water liquid level in the accumulation cavity in real time.

FIG. 3 illustrates a cross-sectional schematic of accumulation cavity oil under horizontal conditions, in accordance with an embodiment of the present disclosure. As shown in fig. 3, in the case of a highly deviated well, we correct the inclination angle as follows, and fig. 3 shows the oil accumulation in the rotary accumulation chamber 7 in the horizontal condition.

In the horizontal condition, the calculation formula (first volume calculation formula) of the oil phase volume in the rotary accumulation cavity is:

V＝L*y₁*w；

in the formula, V represents the volume of oil phase accumulation, L represents the length of the rotary accumulation chamber 7, y₁The accumulated height of the oil phase in the accumulation cavity is represented, and the accumulated height of the oil phase in the accumulation cavity can be calculated according to the number of the oil phase immersed in the conductance probes as the distribution intervals of the conductance probes are equal; w is the width of the rotating accumulation cavity 7 of a regular quadrangular prism.

In the embodiments of the present disclosure and other possible embodiments, the rotary accumulation chamber 7 is a regular quadrangular prism (square), and it is obvious that one skilled in the art can select a suitable shape, such as a rectangle, a circle, a cone, etc., according to actual needs.

Fig. 4 shows a schematic diagram of response law of a probe array corresponding to oil flow measurement under a horizontal condition according to an embodiment of the present disclosure. As shown in FIG. 4, at a fixed flow rate, the response obtained by the conductance probe is time T and the cumulative height y of the liquid level₁The response rule of (2).

In an embodiment of the present disclosure, the measurement method further includes: if the inclination exists, further determining the inclination direction of the logging instrument according to the position information; determining the cumulative volume of the oil phase and the corresponding cumulative time or the phase change volume of the oil phase and the corresponding change time according to the inclination direction, wherein the method comprises the following steps: if the inclination direction is a first direction, determining the oil phase accumulation volume and corresponding accumulation time or oil phase change volume and corresponding change time according to a first probe array arranged at one end of a rotary accumulation cavity 7 and a third probe array arranged at the inner side of the rotary accumulation cavity 7 between the first probe array and the second probe array; if the inclination direction is a second direction opposite to the first direction, determining the oil phase accumulation volume and the corresponding accumulation time or the oil phase change volume and the corresponding change time according to a third probe array installed at the other end of the rotary accumulation cavity 7 and a third probe array installed at the inner side of the rotary accumulation cavity 7 between the first probe array and the second probe array.

FIG. 5 shows a schematic cross-sectional view of the accumulation of oil phase within the accumulation chamber under highly deviated well conditions, according to an embodiment of the present disclosure. Specifically, fig. 5 shows a case where the oil phase is accumulated inside the downhole rotary accumulation chamber 7 under the condition of a high inclination angle (the inclination direction is the first direction). As shown in fig. 5, the volume flow of the oil phase under the pure level condition can be derived by calculating the slope of the step. However, under highly deviated well conditions, the manner of measuring oil flow needs to be calibrated.

Under highly deviated well conditions, the volume calculation formula (second volume calculation formula) of the internal oil phase of the rotary accumulation chamber 7 is:

wherein x is₂The accumulated length, y, of the oil phase inside the accumulation cavity is recorded by the angle correction probe array 8 under the condition of the oil phase in the highly-deviated well₂The oil phase is accumulated in the rotary accumulation cavity 7The height of the liquid level, w, is the width of the regular quadrangular prism rotary accumulation cavity 7.

The cumulative volume of oil under horizontal conditions and highly deviated well conditions at the same time and the same flow rate is the same, so y can be calculated₁、x₂And y₂There is a preset conversion relationship between:

wherein L is the length of the rotary accumulation chamber 7, x₂The length, y, of oil phase accumulation recorded by angle correction probe array 8 for oil phase under highly deviated well conditions₂The level of liquid accumulated inside the rotating accumulation chamber 7 by the array of oil flow measurement probes.

Therefore, x measured by two arrays in a highly-deviated well can be converted into x by presetting conversion relation₂,y₂Equivalent to y measured by an array of oil flow measuring probes under horizontal conditions₁. Thereby realizing the oil flow correction at the horizontal inclination angle.

FIG. 6 shows a schematic diagram of response rules of a probe array corresponding to oil flow measurements under highly deviated well conditions, according to an embodiment of the disclosure. FIG. 6(a) is a schematic diagram of the response rule of an angle-corrected array probe of an accumulation cavity under highly deviated well conditions; FIG. 6(b) is a schematic diagram showing the response law of the oil flow measurement probe array of the accumulation cavity under the condition of a highly deviated well. As shown in FIG. 6, at a constant flow rate, the time T and the cumulative length x of the liquid level can be obtained by the angle correction probe array 8 and the positive angle oil flow rate measurement probe array 11, respectively₂Response law of (2) and time T and liquid level accumulated height y₂The response rule of (2).

At a negative inclination angle (the inclination direction is a second direction opposite to the first direction), when the oil phase flow enters the rotary accumulation cavity 7, the negative angle oil flow measurement probe array 19 and the angle correction probe array 8 are combined to measure the oil flow and correct the inclination angle, and the correction method of the oil flow at the negative inclination angle is consistent with the principle.

The specific embodiment of the short-circuit of the current collector can refer to the umbrella type current collecting method CN 201020611183.8, and is not described in detail in the invention.

In an embodiment of the present disclosure, the tool body has a rotary accumulation cavity 7 on its inside with a drive mechanism; the driving mechanism is used for driving the rotary accumulation cavity 7 to rotate to a set position according to a set position instruction, so that an oil-water mixed phase flows in from the liquid inlet 6 of the rotary accumulation cavity 7, a water phase of the oil-water mixed phase flows out from the liquid outlet 10 of the rotary accumulation cavity 7, and an oil phase of the oil-water mixed phase is accumulated in the rotary accumulation cavity 7. Wherein the drive mechanism comprises: a driving motor 15 and a stationary short circuit 18; one end of the driving motor 15 is connected with the rotary accumulation cavity 7, and the other end of the driving motor 15 is connected with the immobile short circuit 18; the driving motor 15 is driven to rotate reversely through the immobile short circuit 18, so that the rotary accumulation cavity 7 is driven to rotate.

In the embodiment of the present disclosure and other possible embodiments, the driving mechanism may be a rotary driving circuit cylinder short circuit 12, the rotation of the rotary accumulation cavity 7 is realized by a rotary cavity rotary driving motor 15 fixed in the rotary driving circuit cylinder short circuit 12, the body of the driving motor 15 is fixed inside the rotary driving circuit cylinder short circuit 12, the rotor of the rotary cavity rotary driving motor 15 is installed at one end of a hollow fixed rod 17, the other end of the hollow fixed rod 17 is fixed on a fixed short circuit 18, and the fixed short circuit 18 is connected with the combiner casing 5. When the rotary accumulation cavity 7 needs to rotate, positive electricity is supplied to the rotary driving motor 15 of the rotary cavity, the rotating shaft of the driving motor 15 starts to rotate, at the moment, the hollow fixed rod 17 is connected with the combination instrument shell 5 through the fixed short circuit 18, so that the machine body of the rotary driving motor 15 of the rotary cavity can only rotate in the direction opposite to the rotating direction of the rotating shaft, the machine body of the rotary driving motor 15 of the rotary cavity is fixed with the rotary driving circuit cylinder short circuit 12, the rotary driving circuit cylinder short circuit 12 starts to rotate reversely, the rotary driving circuit cylinder short circuit 12 is fixedly connected with the flow accumulation cavity, and the reverse rotation of the flow accumulation cavity is further realized.

In the disclosed embodiment and other possible embodiments, the rotation driving circuit canister short circuit 12 internally contains a combiner circuitry 13, an orientation sensor 14 and a rotatable cavity rotation driving motor 15. In the invention, because a plurality of sensor probe arrays are designed, great inconvenience is brought if the sensor probe arrays are connected by adopting a lead, and therefore, the two groups of probe arrays both adopt a wireless communication mode. The wireless communication is mainly realized by two modules, namely a wireless transmitting module and a wireless receiving module, wherein the wireless transmitting module is arranged in the cavity wall near the probe array, and the wireless receiving module is hermetically arranged in the circuit cylinder. The wireless sending module consists of a coding module and a high-frequency transmitting module, and each conductance probe in the two groups of probe arrays is coded by the coding module and then sent out by the high-frequency transmitting module. The wireless receiving module is used for receiving the data packets sent by the two groups of probe arrays and transmitting the data to the post-processing circuit. The combiner circuit system 13 is mainly used for collecting and processing the measurement signals of the two groups of probe arrays, correcting the influence of the horizontal inclination angle through an algorithm, and transmitting the calculation result to the ground through a cable in a pulse mode. The intersection point of the positive Z-axis direction of the orientation sensor 14 and the shell of the short circuit 12 of the circuit cylinder is positioned on the central connecting line of the liquid inlet 6 and the liquid outlet 10 of the accumulation cavity, that is to say, the liquid inlet 6 and the liquid outlet 10 of the oil flow accumulation cavity and the positive Z-axis direction of the orientation sensor 14 are in the same direction. Therefore, the specific orientation of the liquid inlet 6 and the liquid outlet 10 of the oil flow accumulation cavity in the well can be judged through the response value of the orientation sensor 14. The instrument can only enter the oil flow accumulation measurement mode when the inlet 6 and outlet 10 of the rotating accumulation chamber 7 rotate to the bottom of the flow accumulation chamber.

In embodiments of the present disclosure and other possible embodiments, the rotating accumulation cavity 7 is shaped as a regular quadrangular prism comprising: a liquid inlet 6 of the accumulation cavity, a sealing ring 9, a liquid outlet 10 of the accumulation cavity, an angle correction probe array 8 and an oil flow measurement probe array 11. The accumulation cavity liquid inlet 6 and the accumulation cavity liquid outlet 10 are distributed on the opposite side of the angle correction probe array 8, and the connecting line of the central points of the liquid inlet 6 and the liquid outlet 10 is parallel to the axial lead of the rotary accumulation cavity 7. The accumulation cavity liquid inlet 6 is used for introducing the fluid which is collected into the collecting channel by the umbrella-type current collector 4 into the accumulation cavity, and the accumulation cavity liquid outlet 10 is used for discharging the measured fluid flow in the accumulation cavity out of the accumulation cavity.

In an embodiment of the present disclosure, the tool body has a rotary accumulation cavity 7 on the inside, and a packing mechanism is provided between the tool body and the rotary accumulation cavity 7; and the sealing mechanism is used for isolating the liquid inlet space and the liquid outlet space of the rotary accumulation cavity 7.

In the disclosed embodiment and other possible embodiments, the sealing mechanism may be a sealing ring 9, and the sealing ring 9 is used for sealing the gap between the rotary accumulation cavity 7 and the combiner housing 5, so that the fluid in the collecting channel can only enter the flow accumulation cavity from the accumulation cavity liquid inlet 6.

The working principle of the present disclosure is further explained with reference to fig. 7: firstly, a logging instrument is input into a tested layer section in a highly-deviated well through tractor equipment, and after production is stable, a current collector is opened through ground control. The instrument starts to enter a working state, and the working process of the instrument mainly comprises two steps: the first step is an initialization stage of fluid in the rotary accumulation cavity 7, the ground drives the rotary cavity to rotate the driving motor 15, and simultaneously monitors the output value of the angle sensor 14, when the liquid inlet 6 and the liquid outlet 10 of the rotary accumulation cavity 7 are adjusted to the top of the cavity, the rotation is stopped, after the flowing oil-water mixed phase fluid in the sleeve 3 is collected by the current collector 4, the fluid firstly enters the logging instrument from the liquid inlet 2 of the combination instrument, and then the oil-water mixed phase fluid enters the rotary accumulation cavity 7 from the liquid inlet 6 of the accumulation cavity of the rotary accumulation cavity 7, at this time, because the oil-water mixed phase fluid is acted by gravity, oil-water separation can be generated after entering the rotary accumulation cavity 7, namely, the upper layer is an oil phase, and the lower layer is a water phase. The oil phase fluid will flow in the chamber along the inner wall of the top to exit at the outlet 10 of the rotating accumulation chamber at the top. In the process that the oil phase flow flows out from the inside of the rotary accumulation cavity 7, the array probe in the cavity can monitor the flowing condition of the oil phase, the oil phase enters a stable state when the response value of the probe array is not changed, at the moment, the maximum amount of water and the minimum amount of oil in the cavity are obtained, and initialization is completed. The second step is an oil flow measurement stage, the ground drives the rotatable cavity rotation driving motor 15 to rotate, the output value of the angle sensor 14 is monitored, the rotatable cavity rotation driving motor 15 stops working when the rotary accumulation cavity liquid inlet 6 and the rotary accumulation cavity liquid outlet 10 are adjusted to the bottom of the cavity, and the instrument enters a flow accumulation measurement working mode at the moment. Under the condition of oil-water stratified flow of a low-liquid-production high-gradient well, after flowing oil-water mixed phase fluid in a sleeve 3 flows through a current collector 4, the oil-water mixed phase fluid firstly enters a logging instrument from a liquid inlet 2 of a combination instrument, oil and water can be separated before entering a cavity under the influence of gravity, the oil phase can be accumulated for a period of time, when the oil phase is accumulated to a cavity liquid inlet at the bottom, the oil phase enters a rotary accumulation cavity 7 from a liquid inlet 6 of the accumulation cavity, at the moment, the oil-water mixed phase fluid can be subjected to oil-water separation after entering the rotary accumulation cavity 7 under the action of gravity, namely, the upper layer is the oil phase, and the lower layer is the water phase. The oil phase is accumulated in the rotary accumulation cavity 7, and does not flow out until the oil phase is accumulated to the liquid outlet 10 at the bottom of the rotary accumulation cavity 7. The angle correction probe array 8 and the positive angle oil flow measurement probe array 11 can record the whole process that the oil phase flows into the liquid inlet 6, accumulates in the cavity until the oil phase is full, and then flows out of the liquid outlet 10 at the bottom. During the process of accumulating the oil phase flow to outflow, the method works by recording the process of oil phase fluid flowing from the liquid inlet 6 of the rotatable cavity to the liquid outlet 10 of the accumulation cavity, and obtaining the volume flow of the oil phase according to the response time interval of each probe in the process.

After the test is finished, if the measurement result is not satisfactory, the rotatable cavity can be driven again to rotate the driving motor 15, the liquid inlet and the liquid outlet 610 are adjusted to the top of the rotary accumulation cavity 7 through the orientation sensor 14, the oil phase accumulated in the cavity is released, then the rotatable driving motor 15 is driven again to adjust the liquid inlet 6 and the liquid outlet 10 to the bottom of the rotary accumulation cavity 7, and the oil phase single-phase flow is measured repeatedly until an ideal test result is obtained. After the testing of the interval is finished, the logging combination instrument is conveyed to the next target interval by the tractor equipment to measure the flow and the water content. And finally, after the test is completely finished, lifting the cable, and recovering the logging instrument and the tractor.

In conclusion, the method has the advantages of low flow measurement lower limit, high test precision, basically no movable part of the sensor group and high reliability, can effectively correct the error caused by the inclination angle when the oil flow is measured in the highly-deviated well at present, is suitable for various well logging processes such as tractor conveying, oil pipe conveying and the like, can realize the accurate measurement of the highly-deviated well, and has wide application and development prospects.
