Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of horizontal well logging, in particular, to a horizontal well logging method, device, system, medium and electronic equipment. BACKGROUND

[0002] At present, when the geometry and extension of the horizontal well fracturing fracture are known, the commonly used fracture monitoring methods include well testing analysis, well temperature logging, radioactive tracer logging, microseismic method, etc. Radioactive tracer logging needs to use radioactive tracer ceramic particles, which has certain radioactive pollution to people and environment, and is inconvenient to use.

[0011] In an embodiment of the present application, based on the foregoing scheme, the micro logging instruments are uniformly distributed on the two end faces of the dissolvable bridge plug.

[0012] According to an aspect of the embodiments of the present application, a horizontal well logging device is provided, characterized in that the device comprises: a first acquisition unit configured to acquire, by a micro logging instrument, first temperature data and first pressure data corresponding to a target interval, the first temperature data and the first pressure data being temperature data and pressure data corresponding to the target interval during injection of a fracturing fluid; a second acquisition unit configured to acquire, by the micro logging instrument, second temperature data and second pressure data corresponding to the target interval, the second temperature data and the second pressure data being temperature data and pressure data corresponding to the target interval during diffusion of the fracturing fluid; a third acquisition unit configured to acquire initial acceleration data corresponding to the micro logging instrument, the initial acceleration data representing acceleration data of the micro logging instrument returning to a wellhead of the horizontal well; and a calculation unit configured to calculate, for each interval, a fracture parameter and a reservoir parameter corresponding to each target interval based on the first temperature data, the first pressure data, the second temperature data, the second pressure data, and the initial acceleration data.

[0031] The following describes in detail the implementation of the technical solutions of the embodiments of the application:

[0032] According to an aspect of the application, a horizontal well logging method is provided, Figure 1 For the flow chart of the horizontal well logging method shown in the embodiments of the application, the horizontal well logging method can be executed by a device with computing processing function, and the horizontal well logging method at least includes steps 110 to 140, which are described in detail as follows:

[0033] In step 110, a micro logging instrument is used to obtain first temperature data and first pressure data corresponding to a target interval, wherein the first temperature data and the first pressure data are temperature data and pressure data corresponding to the target interval during injection of fracturing fluid.

[0034] In the present application, in order to improve the accuracy of the fracture parameters and reservoir parameters corresponding to each layer section in the horizontal well, and improve the accuracy of the pressure recovery data corresponding to each layer section in the horizontal well during and after the fracturing process of the horizontal well, firstly, the soluble bridge plug can be placed in the target layer section, the control cable and the perforating gun are moved away from the wellhead of the horizontal well, and the soluble bridge plug in the target layer section is set. Then, the perforating gun is separated from the soluble bridge plug by the control cable, and the perforating gun is moved to a preset position in the target layer section to perform the perforating operation on the target layer section. After the perforating gun perforates, the perforating gun is moved away from the wellhead of the horizontal well by the control cable, and the fracturing fluid is injected into the horizontal well to complete the fracturing operation of the target layer section. During the fracturing process, the first temperature data and the first pressure data corresponding to the target layer section are obtained by the micro logging instrument on the soluble bridge plug. Based on the first temperature data and the first pressure data, the logging analysis of the target layer section during the fracturing process can be performed.

[0035] The soluble bridge plug comprises a single or multiple micro logging instruments, and the micro logging instruments are used to obtain temperature data, pressure data and acceleration data. Based on the first temperature data and the first pressure data, the logging analysis of the target layer section during the fracturing process can be performed.

[0036] Further, in an embodiment of the present application, before the temperature data, the pressure data and the acceleration data corresponding to the micro logging instrument are obtained by the micro logging instrument, the following step can be further included: setting the start time and the data sampling period corresponding to the micro logging instrument, the start time being used to control the micro logging instrument to obtain the temperature data, the pressure data corresponding to the target layer section and the acceleration data corresponding to the micro logging instrument according to the data sampling period.

[0037] Further, in an embodiment of the present application, the micro logging instruments are uniformly distributed on the two end faces of the soluble bridge plug. Referring to Figure 2 , a distribution diagram of the soluble bridge plug according to the embodiment of the present application is shown. In Figure 2-1 , three micro logging instruments are placed on one end face of the soluble bridge plug, and the included angle between adjacent micro logging instruments is 120°. In Figure 2-2 , three micro logging instruments are embedded on the two end faces of the soluble bridge plug, and a pressure guide hole screw is arranged on one end face of the micro logging instrument, and the pressure guide hole screw is used to fix the micro logging instrument on the perforating gun.

[0038] Continuing to refer to Figure 1 , in step 120, the second temperature data and the second pressure data corresponding to the target layer section are obtained by the micro logging instrument, and the second temperature data and the second pressure data are the temperature data and the pressure data corresponding to the target layer section during the diffusion process of the fracturing fluid.

[0039] In the present application, after obtaining the first temperature data and the first pressure data corresponding to the target interval, the second temperature data and the second pressure data corresponding to the target interval are obtained, wherein the second temperature data and the second pressure data are corresponding temperature data and pressure data in the diffusion process of the fracturing fluid. By analyzing the second temperature data and the second pressure data, the pressure recovery condition in the target interval can be understood.

[0040] With reference to the foregoing Figure 1 In step 130, the initial acceleration data corresponding to the micro logging instrument is obtained, and the initial acceleration data represents the acceleration data of the micro logging instrument returning to the wellhead of the horizontal well.

[0041] In the present application, in order to analyze the logging analysis and pressure recovery data of the target interval of the horizontal well after fracturing from the flow level of the wellhead of the horizontal well, the initial acceleration data of the micro logging instrument returning to the wellhead of the horizontal well under the action of the produced fluid can be obtained by the micro logging instrument. Specifically, based on the known wellhead area in the actual production process and the initial acceleration data obtained by the micro logging instrument, the flow data of the wellhead of the horizontal well can be calculated, so that the logging analysis and pressure recovery data of the target interval after fracturing are analyzed based on the flow data.

[0042] In one embodiment of the present application, after obtaining the initial acceleration data, the method specifically further includes steps 131 to 133:

[0043] Step 131: For each target interval, the moving distance and the moving time of the micro logging instrument corresponding to the target interval are obtained, wherein the moving distance is the distance difference between adjacent target intervals, and the moving time is the time difference of the micro logging instrument returning to the wellhead of the horizontal well in adjacent target intervals.

[0044] Step 132: According to the moving distance and the moving time, the average moving speed of the micro logging instrument corresponding to the target interval is calculated.

[0045] Step 133: Based on each average moving speed, the initial acceleration data is corrected.

[0046] In this embodiment, the initial acceleration data of the horizontal well is directly obtained by the micro logging instrument, which may cause errors in the obtained initial acceleration data. Therefore, the distance difference between adjacent target intervals and the time difference between adjacent target intervals can be used to obtain the moving distance and moving time of the micro logging instrument in the target interval. The average moving speed of the micro logging instrument in the target interval can be accurately calculated based on the obtained moving distance and moving time. The initial acceleration data obtained by the micro logging instrument is corrected based on the calculated average moving speed.

[0047] Referring to Figure 3 , a schematic diagram of a horizontal well downhole is shown according to an embodiment of the present application. After obtaining the first temperature data, the first pressure data, the second temperature data, the second pressure data and the initial acceleration data corresponding to each target interval, the distance S1 and the time T1 of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the first target interval are obtained. The distance S2 and the time T2 of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the second target interval are obtained. Therefore, the distance difference between the first target interval and the first target interval is S1-S2, and the time difference between the first target interval and the first target interval is T1-T2. That is, the moving distance corresponding to the first target interval is S1-S2, and the moving time corresponding to the first target interval is T1-T2. Based on the moving distance S1-S2 and the moving time T1-T2, the average moving speed V1 corresponding to the first target interval is calculated, and the initial acceleration data is corrected according to the average moving speed corresponding to the first target interval.

[0048] By analogy, the moving distance corresponding to the second target interval is S2-S3, and the moving time corresponding to the second target interval is T2-T3. Wherein, S2 is the distance of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the second target interval, and S3 is the distance of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the third target interval. T2 is the time of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the second target interval, and T3 is the time of the micro logging instrument returning to the wellhead of the horizontal well corresponding to the third target interval. Based on the moving distance S2-S3 and the moving time T2-T3, the average moving speed V2 corresponding to the second target interval is calculated, and the initial acceleration data is corrected according to the average moving speed corresponding to the second target interval.

[0049] In one embodiment of the present application, the initial acceleration data is corrected based on each average moving speed, specifically including steps 134 to 135:

[0050] In step 134, initial moving speeds corresponding to each target layer section are obtained based on the initial acceleration data, wherein the initial moving speed is the moving speed of the micro logging instrument in the target layer section obtained by the acceleration sensor.

[0051] In step 135, the average moving speed is taken as the initial moving speed corresponding to the target layer section to correct the initial acceleration data.

[0052] In this embodiment, the initial acceleration data of the micro logging instrument returning to the wellhead of the horizontal well from the target layer section is obtained based on the three-axis acceleration sensor and the three-axis gyroscope in the micro logging instrument, so as to obtain the initial moving speed of the micro logging instrument returning to the wellhead of the horizontal well from the target layer section. Since the three-axis acceleration sensor and the three-axis gyroscope will cause signal loss and signal error due to interference of various factors in the process of obtaining the acceleration signal and the micro logging instrument deviation signal, the accuracy of the obtained initial acceleration is affected. Therefore, the average moving speed corresponding to the target layer section can be calculated by obtaining the moving distance and the moving time of the micro logging instrument returning to the wellhead of the horizontal well from the target layer section. Then, the average moving speed is taken as the initial moving speed corresponding to the target layer section to correct the initial acceleration data. Continue to refer to the first target layer section as an example. Figure 3 After the average moving speed V1 corresponding to the first target layer section is calculated, the initial moving speed V01 corresponding to the first target layer section is obtained according to the initial acceleration data, so that the average moving speed V1 is taken as the initial moving speed corresponding to the first target layer section to correct the initial acceleration data.

[0053] Continue to refer to Figure 1 In step 140, for each layer section, the fracture parameters and the reservoir parameters corresponding to each target layer section are calculated based on the first temperature data, the first pressure data, the second temperature data, the second pressure data and the initial acceleration data.

[0054] In this application, first, the first temperature data and the first pressure data in the target layer section are obtained by placing the soluble bridge plug carrying the micro logging instrument in the target layer section during the process of injecting the fracturing fluid. Then, the second temperature data and the second pressure data in the target layer section are obtained by the micro logging instrument during the process of fracturing fluid diffusion. Before the initial acceleration data is obtained, the pressure corresponding to the target layer section is controlled by closing the wellhead of the horizontal well. Based on the pressure corresponding to the target layer section, the density of the produced liquid corresponding to the target layer section, and the density corresponding to the micro logging instrument, the micro logging instrument is controlled to return to the wellhead of the horizontal well, and the density of the produced liquid is the mixed density of the fracturing fluid and the formation water. Therefore, the initial acceleration data of the micro logging instrument returning to the wellhead of the horizontal well from the target layer section can be obtained.

[0055] According to the first temperature data, the first pressure data, the second temperature data, the second pressure data and the initial acceleration data, the fracture parameters and the reservoir parameters corresponding to the target layer section can be calculated, so as to perform logging analysis and pressure recovery analysis in the fracturing process and fracturing diffusion of the target layer section based on the fracture parameters and the reservoir parameters.

[0056] The above steps are repeated to obtain the first temperature data, the first pressure data, the second temperature data, the second pressure data and the initial acceleration data corresponding to each target layer section, so as to calculate the fracture parameters and the reservoir parameters corresponding to each target layer section. Based on the fracture parameters and the reservoir parameters, the accuracy of analyzing the pressure recovery of each layer section can be improved, and multi-layer section analysis of the horizontal well can be realized.
