[0002] This application claims priority to Chinese patent application No. 202410186373.6 filed on February 19, 2024, and cites the contents disclosed in the above patent application as part of this application. Technical Field

[0003] The embodiments of the present disclosure relate to the field of oil and gas well fracturing, and in particular, to a fracturing method, apparatus, equipment, and storage medium for horizontal wells. Background Art

[0004] Existing horizontal well fracturing technology mainly uses the same fracturing method and concept, that is, the fracturing method of each horizontal well on the platform to be fractured is the same. Although differentiated designs are made based on the heterogeneity of the horizontal section reservoir, the design parameters of different sections may vary, but the overall strength remains unchanged. This identical fracturing method does not fully consider the impact of reservoir heterogeneity on the uneven distribution of hydraulic fractures, resulting in mutual interference and pressure channeling between wells.

[0005] Therefore, there is an urgent need for a fracturing method for horizontal wells that can reduce inter-well interference and pressure channeling of horizontal wells on the platform to be fractured, thereby increasing production and efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0058] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the embodiments of the present disclosure.

[0059] Existing horizontal well fracturing technology mainly uses the same fracturing method and concept, that is, the fracturing method of each horizontal well on the platform to be fractured is the same. Although differentiated designs are made based on the heterogeneity of the horizontal section reservoir, the design parameters of different sections may vary, but the overall strength remains unchanged. This identical fracturing method does not fully consider the impact of reservoir heterogeneity on the uneven distribution of hydraulic fractures, resulting in mutual interference and pressure channeling between wells.

[0060] In order to solve the above problems, the embodiments of the present disclosure provide a fracturing method for horizontal wells. Figure 1 is a flow chart of a fracturing method for horizontal wells provided by the embodiments of the present disclosure. The present disclosure provides method operation steps such as the embodiments or flow charts, but based on conventional or non-creative work, more or fewer operation steps may be included.

[0061] It should be noted that the terms "first", "second", etc. in the description and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

[0062] 1 , an embodiment of the present disclosure provides a fracturing method for a horizontal well, comprising:

[0063] S101: Determine a horizontal well fracturing pattern consisting of at least one structural framework well and at least one enhanced production well based on reservoir heterogeneity and natural fracture conditions of the platform to be fractured, wherein the structural framework wells and the enhanced production wells in the horizontal well fracturing pattern are arranged in an intersecting manner;

[0064] S102: Evaluate the three-dimensional reservoir quality of the structural framework well through well logging curves, and select and obtain the fracturing and perforation sections of the structural framework well based on the three-dimensional reservoir quality and natural fracture conditions of the structural framework well;

[0065] S103: Evaluate the three-dimensional reservoir quality of the enhanced production well through well logging curves, and select the fracturing and perforation sections of the enhanced production well based on the three-dimensional reservoir quality and natural fracture conditions of the enhanced production well;

[0066] S104: setting the fracturing mode and fracturing parameters of the fracturing perforation section of the structural framework well, and the fracturing mode and fracturing parameters of the fracturing perforation section of the enhanced production well;

[0067] S105: Fracturing the fracturing perforation section of the structural framework well based on the fracturing method and fracturing parameters of the fracturing perforation section of the structural framework well, and obtaining the distribution of the fractures during the fracturing process;

[0068] S106: Based on the distribution of the fractures in the fracture perforation section of the structural framework well, optimizing the fracturing mode and fracturing parameters of the fracture perforation section of the enhanced production well adjacent to the structural framework well;

[0069] S107: Fracturing the perforation section of the enhanced production well according to the optimized fracturing method and fracturing parameters.

[0070] A horizontal well fracturing pattern includes framework wells and enhanced production wells. Based on the reservoir heterogeneity and natural fractures of the platform to be fractured, horizontal wells with weak reservoir heterogeneity and no natural fractures are selected as framework wells, while horizontal wells adjacent to the framework wells are selected as enhanced production wells. Weak heterogeneity refers to a horizontal well's weaker heterogeneity than its adjacent horizontal wells, and lack of natural fractures refers to the absence of natural fractures or a number of natural fractures less than a preset number, which can be determined based on actual needs. The framework wells and enhanced production wells in the horizontal well fracturing pattern are arranged in an interleaved pattern. This interleaved pattern means that the framework wells are spaced apart from the enhanced production wells, for example, ABABA..., where A is the enhanced production well and B is the framework well. As shown in Figure 10, in one example, enhanced production well A and framework well B are arranged in an interleaved pattern. The present disclosure no longer uses the same fracturing strategy for horizontal wells on the same platform to be fractured. Instead, the horizontal wells are differentiated. The structural framework wells play a role in large-scale fracture creation and framework construction during fracturing, while the reinforced production wells play a role in detecting and repairing leaks and assisting production. Different fracturing methods, fracturing parameters, and implementation sequences are adopted for the structural framework wells and the reinforced production wells. The fracturing method of the present invention is applicable to platforms to be fractured with 5 or more horizontal wells, generally 5-9 wells, including 2-4 structural framework wells and 3-5 reinforced production wells, to achieve fracture control and inter-well energy replenishment and oil recovery on the platform to be fractured.

[0071] For structural framework wells and enhanced production wells, not all well sections need to be fractured. Instead, the fracturing and perforation sections need to be screened and only the fracturing and perforation sections need to be fractured. The selection of fracturing and perforation sections is related to the three-dimensional reservoir quality and natural fracture conditions. It should be noted that the three-dimensional reservoir quality refers to the three-dimensional reservoir quality of the three-dimensional geology where the structural framework well or enhanced production well is located.

[0072] The fracturing methods and parameters for the structural framework well and the enhanced production well's fracturing perforation sections are different and need to be set separately. Furthermore, the implementation order for the structural framework well and the enhanced production well is different. Specifically, the structural framework well's fracturing perforation section is first fractured, and the distribution of the fracturing during the fracturing process is simultaneously obtained. To prevent the fracturing of the enhanced production well from colluding with the fracturing of the adjacent framework well, it is necessary to optimize the fracturing method and parameters of the adjacent enhanced production well's fracturing perforation section based on the distribution of the fracturing in the structural framework well's fracturing perforation section. The enhanced production well's fracturing perforation section is then fractured based on the optimized fracturing method and parameters.

[0073] Through the method of the embodiment of the present disclosure, it is possible to determine the horizontal well fracturing pattern produced by the cross-arrangement of the structural framework wells and the enhanced production wells according to the heterogeneity and natural fracture conditions of the platform to be fractured, evaluate the three-dimensional spatial reservoir quality of the structural framework wells and the enhanced production wells through the well logging curve, and further select the fracturing perforation section according to the three-dimensional spatial reservoir quality and the natural fracture conditions. After setting the fracturing method and fracturing parameters of the fracturing perforation section of the structural framework well and the fracturing method and fracturing parameters of the fracturing perforation section of the enhanced production well, the fracturing perforation section of the structural framework well is first fractured, and large-scale fractures are created and the framework is built. At the same time, the distribution of the fractures during the fracturing process is obtained. Based on the distribution of the fractures, the fracturing method and fracturing parameters of the fracturing perforation section of the enhanced production well adjacent to the structural framework well are optimized. Then, the fracturing perforation section of the enhanced production well is fractured to check for deficiencies and fill gaps and assist in production. In this way, the interference and pressure channeling between the horizontal wells on the platform to be fractured can be reduced, thereby increasing production and efficiency.

[0074] In an embodiment of the present disclosure, referring to FIG. 2 , evaluating the three-dimensional reservoir quality of a structural framework well by means of well logging curves, and selecting and obtaining the fracturing and perforating sections of the structural framework well according to the three-dimensional reservoir quality and natural fracture conditions of the structural framework well further includes:

[0075] S201: Obtaining lithologic data, physical data, and oil content data of the structural framework well through natural gamma ray logging curves, acoustic transit time logging curves, density logging curves, and resistivity logging curves;

[0076] S202: Obtaining a three-dimensional reservoir quality value of the structural framework well based on the lithology data, physical property data, and oil content data of the structural framework well;

[0077] S203: Eliminate the well section with natural fractures in the structural framework well to obtain the structural framework well after elimination;

[0078] S204: Screening the eliminated structural framework wells to obtain well sections with three-dimensional reservoir quality values ​​higher than a first set threshold value, and using them as fracturing and perforation sections of the structural framework wells.

[0079] Among them, the natural gamma logging curve can determine the lithologic data of the structural framework well or the enhanced production well, and the lithologic data is specifically the mud content. The sonic time difference logging curve can determine the physical property data of the structural framework well or the enhanced production well. The density logging curve can also determine the physical property data of the structural framework well or the enhanced production well, and the physical property data is specifically the porosity. The resistivity logging curve can determine the oil content data of the structural framework well or the enhanced production well, and the oil content data is specifically the resistivity.

[0080] The 3D reservoir quality of the framework well is calculated based on the shale content, porosity, and resistivity of the framework well. The 3D reservoir quality of the enhanced production well is calculated based on the shale content, porosity, and resistivity of the enhanced production well. Since 3D reservoir quality refers to the 3D reservoir quality of the geology within the framework or enhanced production well, the shale content, porosity, and resistivity mentioned above all refer to the geology within the framework or enhanced production well.

[0081] Because artificial fractures are required in the fracturing perforation sections, the screened fracturing perforation sections must not contain natural fractures, otherwise the artificial fractures will not be fully covered during the subsequent fracturing process. Further, the well sections containing natural fractures in the structural framework wells are eliminated to obtain the eliminated structural framework wells. For the eliminated structural framework wells, it is necessary to screen the well sections whose three-dimensional reservoir quality values ​​exceed a first set threshold. Specifically, the average of the three-dimensional reservoir quality values ​​of the eliminated structural framework wells can be used as the first set threshold. The three-dimensional reservoir quality value at the current depth position is determined one by one along the well depth direction to determine whether it exceeds the first set threshold. If so, the current depth position is used as the first position. Starting from the first position, the three-dimensional reservoir quality values ​​of other depth positions are compared with the first set threshold. If the three-dimensional reservoir quality value of any other depth position is not greater than the first set threshold, the other depth position is used as the second position, and the well section from the first position to the second position is used as the fracturing perforation section of the structural framework well. The fracturing perforation section includes the first position and does not include the second position. The other depth positions are positions located after the first position along the well depth direction. Whether the three-dimensional spatial reservoir quality value of each depth position is greater than a first set threshold value is determined one by one along the well depth direction. If not, whether the three-dimensional spatial reservoir quality value of the depth position after the current depth position is greater than the first set threshold value is determined along the well depth direction. The above determination steps are repeated until the three-dimensional spatial reservoir quality values ​​of all depth positions along the well depth direction are determined. In this way, at least one fracturing perforation section can be obtained.

[0082] The first set threshold value can be the average value of the three-dimensional reservoir quality value of the structural framework well after elimination, or it can be other reasonable values ​​such as the median value. The present disclosure does not limit this. The fracturing perforation section obtained by quantitative characterization can achieve precise fracturing and improve reservoir utilization.

[0083] Similarly, referring to FIG3 , the three-dimensional reservoir quality of the enhanced production well is evaluated by the well logging curve, and the fracturing and perforation section of the enhanced production well is screened based on the three-dimensional reservoir quality and natural fracture conditions of the enhanced production well, further including:

[0084] S301: Obtaining lithologic data, physical data, and oil content data of the enhanced production wells through natural gamma ray logging curves, acoustic transit time logging curves, density logging curves, and resistivity logging curves;

[0085] S302: Obtaining a three-dimensional reservoir quality value of the enhanced production well based on the lithology data, physical property data, and oil content data of the enhanced production well;

[0086] S303: Eliminate the well section with natural fractures in the enhanced production well to obtain the enhanced production well after elimination;

[0087] S304: Screening the eliminated enhanced production wells to obtain well sections with three-dimensional reservoir quality values ​​higher than a second set threshold value, and using them as fracturing and perforation sections for the enhanced production wells.

[0088] The method for determining the fracturing and perforation sections of the enhanced production wells is similar to that of the structural framework wells and will not be further described in this disclosure. The second threshold is used for determination. The second threshold can be the average of the three-dimensional reservoir quality values ​​of the enhanced production wells after elimination, or another reasonable value such as the median value, which is not limited in this disclosure.

[0089] In the embodiment of the present disclosure, setting a fracturing method for a fracturing perforation section of a structural framework well includes: setting an operation process and a fracture layout strategy for the fracturing perforation section of the structural framework well; setting fracturing parameters for a fracturing perforation section of the structural framework well includes: setting fracture parameters, operation displacement, and operation parameters for the fracturing perforation section of the structural framework well;

[0090] Setting the fracturing method of the fracturing perforation section of the enhanced production well includes: setting the operation process and fracture layout strategy of the fracturing perforation section of the enhanced production well; setting the fracturing parameters of the fracturing perforation section of the enhanced production well includes setting the fracture parameters, construction displacement and construction parameters of the fracturing perforation section of the enhanced production well.

[0091] Among them, the operating process of the fracturing and perforating section of the structural frame well is continuous fracturing with bridge plug / ball seat perforation, and the seam layout strategy is single-section multi-cluster seam layout. For example, a single fracturing section is generally perforated in 3 to 5 clusters, with a section length of 30 to 50 meters. The fracture parameters include the number of fracturing sections and fracturing clusters, and the construction parameters include the amount of liquid injected into the ground, the amount of fracturing fluid and the amount of added sand, so as to achieve energy replenishment and inter-well oil displacement.

[0092] The operating process for strengthening the fracturing and perforating section of production wells is continuous fracturing with bridge plug / ball seat perforation, or hydraulic jet fracturing with coiled tubing and bottom seal dragging. The seam layout strategy is single-segment multi-cluster seam layout. For example, a single fracturing section is generally perforated in one cluster, with a section length of 10 to 30 meters. The fracture parameters include the number of fracturing sections and the number of fracturing clusters. The construction parameters include the amount of liquid injected into the ground, the amount of fracturing fluid and the amount of added sand. In this way, every seam can be exploited to maximize the utilization of the reserves of the platform to be fractured.

[0093] Based on the fracturing mode and fracturing parameters of the structural framework well's fracturing perforation section, the structural framework well's fracturing perforation section is fractured, and the distribution of the fractures during the fracturing process is obtained. It should be noted that only the fracturing perforation section is fractured, and the other sections of the structural framework well are not fractured. In the disclosed embodiment, the fracture distribution is obtained by combining the effective coverage of the fracture on the reservoir represented by the microseismic monitoring results and the reservoir pressure change data represented by the pressure monitoring results. Specifically, refer to the fracture distribution diagram of Figure 9. The fracture distribution is obtained based on the microseismic monitoring results (Figure 8) and the pressure monitoring results. All points in Figure 8 represent the range that the fracture may cover. The pressure monitoring results indicate whether the fracture is opened through pressure changes. According to the fracturing construction, the construction pressure will change accordingly during the process of increasing the displacement, increasing the liquid volume, and pumping the proppant. Combined with the pressure change characteristics obtained based on the pressure monitoring results, the length and width of the fracture extension can be predicted, and the coverage of the fracture on the reservoir can be evaluated.

[0094] Furthermore, based on the distribution of the hydraulic fractures in the structural framework well, optimizing the hydraulic fracturing mode and hydraulic fracturing parameters of the hydraulic perforation section of the enhanced production well adjacent to the structural framework well further includes:

[0095] Based on the distribution of the hydraulic fractures in the structural framework wells, the operation process is optimized, and the pre-fluid is controlled by the end-sanding technology, so that the pre-fluid is completely lost before the sand-carrying fluid reaches the dynamic fracture tip of the enhanced production well. The sand-carrying fluid is desanded to form sand plugs, which prevent the hydraulic fractures of the enhanced production wells from being connected with the hydraulic fractures of the adjacent structural framework wells. By quickly reducing the displacement, the amount of liquid entering the formation and the amount of fluid lost to the formation through the fracture are balanced or underbalanced, so that the liquid (including the pre-fluid and the sand-carrying fluid) at the front end / tip of the fracture injected by the pre-pump is completely lost, which is not enough to make the fracture further expand and extend, thereby achieving the purpose of controlling the end of the fracture. Both the fluid and the pre-fluid are fracturing fluids. The fracturing fluid pumped into the formation includes pre-fluid and sand-carrying fluid. The pre-fluid refers to the liquid without sand that is pumped into the formation in the early stage of fracturing. The sand-carrying fluid refers to the period after the pre-fluid pumping stage is completed, when cracks with a certain opening and length have been formed, which can meet the requirements of the liquid carrying sand to enter and use the sand to support the cracks. In this stage, the sand-carrying fluid is used to mix sand with a certain solid concentration and inject it into the formation to continue to complete the further expansion and support of the cracks; optimize the construction displacement, and when sand is continuously added, control the fracture length of the enhanced production well to remain unchanged, and increase the fracture width to form a short and wide fracture in the enhanced production well.

[0097] Referring to Figure 6, there are six horizontal wells in the platform to be fractured, including the structural framework wells EC1 and EC2, and the adjacent enhanced production wells RP1, RP2, and RP3. The figure shows the cross-arrangement of the structural framework wells and the enhanced production wells. Referring to Figure 7, the well logging curves and calculated three-dimensional reservoir quality (GQ) values ​​for the structural framework wells and the enhanced production wells are shown. Referring to Table 1, the fracturing method and parameters for the fracturing perforation section of the structural framework wells, as well as the fracturing method and parameters for the fracturing perforation section of the enhanced production wells, are shown.

[0098] Table 1

[0099] Figure 8 shows the effective reservoir coverage of the fractures, as measured by microseismic monitoring during the fracturing process in the perforated section of the structural framework well. Figure 9 shows the comprehensive distribution of the fractures. Based on this distribution, the fracturing method and parameters for the perforated section of the production well were optimized.

[0100] The structural framework well (EC) was completed in the first round of implementation. Through multi-cluster, large-scale fracturing and oil displacement fracturing fluid, the fracturing parameters were a fracture density of 5 to 8 per 100 meters and a fluid strength of 15 to 20 m 3 / m, and implement appropriate monitoring measures to evaluate the effective coverage of the current fractures. The second round of enhanced production wells (RP) was implemented through precise segmentation, scale control, fiber fracturing fluid, and fracturing parameters of 2 to 3 fractures per 100 meters and 8 to 12m 3 / m, the design target is the remaining volume of fine fracturing.

[0101] Referring to Figure 11, the left figure is a comparison of the average production of the test well A1 using the structured oil recovery fracturing method according to the embodiment of the present disclosure and the comparison well B1 using the conventional fracturing method for 30 consecutive days. The right figure is a comparison of the average production of the test well A2 using the structured oil recovery fracturing method according to the embodiment of the present disclosure and the comparison well B2 using the conventional fracturing method for 90 consecutive days. Among them, structured oil recovery fracturing is fracturing using the horizontal well fracturing well network of the embodiment of the present disclosure; conventional fracturing is fracturing in the same way for each horizontal well on the platform to be fractured. It can be seen that after adopting the structured oil recovery fracturing method of the embodiment of the present disclosure, the average daily oil production is significantly improved.

[0102] Furthermore, as shown in Figures (a) to (d) of Figure 12, Figure (a) shows a comparison of the sand addition intensity of the test well A1 of the structured oil displacement fracturing according to the embodiment of the present disclosure and the comparison well B1 using conventional fracturing methods, Figure (b) shows a comparison of the fluid intensity of the test well A1 of the structured oil displacement fracturing according to the embodiment of the present disclosure and the fluid intensity of the comparison well B1 using conventional fracturing methods, Figure (c) shows a comparison of the sand volume of the test well A1 of the structured oil displacement fracturing according to the embodiment of the present disclosure and the sand volume of the comparison well B1 using conventional fracturing methods, and Figure (d) shows a comparison of the fluid volume of the test well A1 of the structured oil displacement fracturing according to the embodiment of the present disclosure and the comparison well B1 using conventional fracturing methods. It can be seen that after adopting the structured oil displacement fracturing according to the embodiment of the present disclosure, the sand addition intensity, fluid intensity, sand volume, and fluid volume all decreased. Therefore, the use of structured oil displacement fracturing can reduce costs while increasing the average daily oil production.
