Description

[0002] At present, in understanding the geometry and extension of horizontal well fracturing cracks, commonly used fracture monitoring methods include well test analysis, well temperature logging, radioactive tracer logging, microseismic method, etc. Radioactive tracer logging requires the use of radioactive tracer ceramsite, which has certain radioactive pollution to humans and the environment and is inconvenient to use. The microseismic method requires the deployment of a large number of geophones on the ground or underground, and the construction process is complex, the cycle is long, and the price is expensive. In addition, the method itself has certain uncertainties and lacks the necessary comparative verification methods. The interpretation of data errors needs to be further understood.

[0010] In one embodiment of the present application, based on the aforementioned scheme, before obtaining the initial acceleration data, the method also includes: controlling the pressure corresponding to the target layer segment by closing the wellhead of the horizontal well; based on the pressure corresponding to the target layer segment, the density of the produced fluid corresponding to the target layer segment, and the density corresponding to the micro-logging instrument, controlling the micro-logging instrument to return to the wellhead of the horizontal well, the density of the produced fluid being the mixed density of the fracturing fluid and formation water.

[0011] In one embodiment of the present application, based on the above-mentioned solution, the micro logging instruments are evenly distributed on the two end surfaces of the soluble bridge plug.

[0012] According to one aspect of an embodiment of the present application, a horizontal well logging device is provided, characterized in that the device includes: a first acquisition unit, used to acquire first temperature data and first pressure data corresponding to a target layer segment through a micro-logging instrument, the first temperature data and the first pressure data being the temperature data and the pressure data corresponding to a process of injecting fracturing fluid into the target layer segment; a second acquisition unit, used to acquire second temperature data and second pressure data corresponding to the target layer segment through the micro-logging instrument, the second temperature data and the second pressure data being the temperature data and the pressure data corresponding to a process of fracturing fluid diffusion in the target layer segment; a third acquisition unit, used 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 the wellhead of the horizontal well; a calculation unit, used to calculate, for each layer segment, fracture parameters and reservoir parameters corresponding to each of the target layer segments 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 implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0032] According to one aspect of the present application, a horizontal well logging method is provided. Figure 1 The flowchart of the horizontal well logging method according to the embodiment of the present application is shown. The horizontal well logging method can be performed by a device with a computing and processing function. The horizontal well logging method includes at least steps 110 to 140, which are described in detail as follows:

[0033] In step 110, first temperature data and first pressure data corresponding to the target layer segment are obtained by using a micro logging instrument. The first temperature data and the first pressure data are the temperature data and the pressure data corresponding to the process of injecting fracturing fluid into the target layer segment.

[0034] In the present application, in order to improve the accuracy of fracture parameters and reservoir parameters corresponding to each layer section in the horizontal well, and to improve the accuracy of pressure recovery data corresponding to each layer section in the horizontal well during and after the fracturing of the horizontal well, firstly, by placing a soluble bridge plug in the target layer section, controlling the cable and the perforating gun to leave the wellhead of the horizontal well, and setting the soluble bridge plug in the target layer section. Then, the perforating gun is separated from the soluble bridge plug by controlling the cable, and the perforating gun is controlled to move to a preset position in the target layer section to perform a perforating operation on the target layer section. After the perforating gun perforates, the perforating gun is again controlled by the cable to leave the wellhead of the horizontal well, and 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 during the fracturing process can be performed on the target layer section.

[0035] The soluble bridge plug includes 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, logging analysis can be performed on the target layer section during the fracturing process.

[0036] Furthermore, in one embodiment of the present application, before obtaining temperature data, pressure data and acceleration data corresponding to the micro-logging instrument through the micro-logging instrument, the following steps may also be included: setting a start time and a data sampling period corresponding to the micro-logging instrument, wherein the start time is used to control the micro-logging instrument to obtain the temperature data, pressure data corresponding to the target layer segment and the acceleration data corresponding to the micro-logging instrument according to the data sampling period.

[0037] Further, in one embodiment of the present application, the micro logging instruments are evenly distributed on the two end surfaces of the soluble bridge plug. Figure 2 , is a soluble bridge plug distribution diagram according to an embodiment of the present application. Figure 2-1 In the example, three micro-logging instruments are placed on one end face of the soluble bridge plug, and the angle between adjacent micro-logging instruments is 120°. Figure 2-2 In the present invention, three micro-logging instruments are embedded in both end faces of the soluble bridge plug, and a screw with a pressure-conducting hole is provided on one end face of the micro-logging instrument, and the screw with a pressure-conducting hole is used to fix the micro-logging instrument on the perforating gun.

[0038] Continue to refer to Figure 1 In step 120, the second temperature data and the second pressure data corresponding to the target layer segment are obtained through 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 diffusion process of the fracturing fluid in the target layer segment.

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

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

[0041] In this application, in order to be able to perform post-fracture logging analysis and pressure recovery data analysis on the target layer section of the horizontal well from the flow level of the horizontal wellhead. 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 through a 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, and then based on the flow data, the post-fracture logging analysis and pressure recovery data of the target layer section can be analyzed.

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

[0043] Step 131, for each target layer segment, obtain the corresponding moving distance and moving time of the micro logging instrument in the target layer segment, wherein the moving distance is the distance difference between adjacent target layer segments, and the moving time is the time difference between the micro logging instruments in adjacent target layer segments returning to the wellhead of the horizontal well.

[0044] Step 132, calculating the average moving speed of the micro logging instrument corresponding to the target layer segment according to the moving distance and the moving time.

[0045] Step 133: correcting the initial acceleration data based on the average moving speeds.

[0046] In this embodiment, since the initial acceleration data of the horizontal well is directly obtained through the micro-logging instrument, the initial acceleration data obtained will produce errors. Therefore, the moving distance and moving time corresponding to the micro-logging instrument in the target layer section can be obtained according to the distance difference between adjacent target layers and the time difference of the micro-logging instrument in adjacent target layers returning to the wellhead of the horizontal well. The average moving speed of the micro-logging instrument in the target layer section can be accurately calculated by the obtained moving distance and moving time. Based on the calculated average moving speed, the initial acceleration data obtained by the micro-logging instrument is corrected.

[0047] Reference Figure 3 , is a schematic diagram of a horizontal well 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 layer segment, taking the first target layer segment and the second target layer segment as examples, the distance S1 and the time T1 of the micro-logging instrument corresponding to the first target layer segment back to the wellhead of the horizontal well are obtained. The distance S2 and the time T2 of the micro-logging instrument corresponding to the second target layer segment back to the wellhead of the horizontal well are obtained. Therefore, the distance difference between the first target layer segment and the first target layer segment is S1-S2, and the time difference between the first target layer segment and the first target layer segment is T1-T2. That is, the moving distance corresponding to the first target layer segment is S1-S2, and the moving time corresponding to the first target layer segment is T1-T2. Based on the moving distance S1-S2 and the moving time T1-T2, the average moving speed corresponding to the first target layer segment is calculated as V1, so as to correct the initial acceleration data according to the average moving speed corresponding to the first target layer segment.

[0048] By analogy, the moving distance corresponding to the second target layer segment is S2-S3, and the moving time corresponding to the second target layer segment is T2-T3. Among them, S2 is the distance of the micro-logging instrument corresponding to the second target layer segment returning to the wellhead of the horizontal well, and S3 is the distance of the micro-logging instrument corresponding to the third target layer segment returning to the wellhead of the horizontal well. T2 is the time for the micro-logging instrument corresponding to the second target layer segment to return to the wellhead of the horizontal well, and T3 is the time for the micro-logging instrument corresponding to the third target layer segment to return to the wellhead of the horizontal well. Based on the moving distance S2-S3 and the moving time T2-T3, the average moving speed corresponding to the second target layer segment is calculated as V2, so that the initial acceleration data is corrected according to the average moving speed corresponding to the second target layer segment.

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

[0050] Step 134, based on the initial acceleration data, obtaining the initial moving speed corresponding to each target layer segment, wherein the initial moving speed is the moving speed of the micro logging instrument in the target layer segment obtained by the acceleration sensor.

[0051] Step 135: Using the average moving speed as the initial moving speed corresponding to the target layer segment to correct the initial acceleration data.

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

[0053] Continue to refer to Figure 1 In step 140, for each layer segment, based on 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 reservoir parameters corresponding to each target layer segment are calculated.

[0054] In the present application, first, by placing a soluble bridge plug carrying a micro-logging instrument in the target layer segment, the first temperature data and the first pressure data in the target layer segment are obtained during the injection of the fracturing fluid. Then, during the diffusion of the fracturing fluid, the second temperature data and the second pressure data in the target layer segment are obtained by the micro-logging instrument. Wherein, before obtaining the initial acceleration data, the pressure corresponding to the target layer segment is controlled by closing the wellhead of the horizontal well. Based on the pressure corresponding to the target layer segment, the density of the produced fluid corresponding to the target layer segment, 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 fluid is the mixed density of the fracturing fluid and the formation water. Therefore, the initial acceleration data of the micro-logging instrument returning from the target layer segment to the wellhead of the horizontal well 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 reservoir parameters corresponding to the target layer segment can be calculated, so as to perform logging analysis and pressure recovery analysis during the fracturing process and fracturing diffusion of the target layer segment based on the fracture parameters and the reservoir parameters.

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