[0002] Since 2015, reservoir geologists have generally believed that strike-slip faults have a significant control on oil and gas accumulation, especially in the carbonate rock field of the Tarim Basin, where the control of reservoirs by strike-slip faults is particularly critical. Therefore, the study of the boundary of ultra-deep strike-slip faults controlling reservoirs is very important.

[0003] At present, the research on carbonate oil and gas accumulation mainly focuses on the accumulation process, accumulation period and accumulation dynamic mechanism, and is mainly applied in the field of oil and gas exploration, while there is less research on oil fields that are currently in the middle and late stages of development. Therefore, there is an urgent need for a method to determine the boundary of ultra-deep strike-slip faults to control the accumulation, so as to provide technical support for the efficient exploration and development of carbonate oil reservoirs. Summary of the invention

[0036] Embodiment 1

[0037] Figure 1A flowchart of a method for determining the boundary of an ultra-deep strike-slip fault controlled reservoir is provided for the first embodiment of the present invention. This embodiment can be applied to determine the boundary of an ultra-deep strike-slip fault controlled reservoir in an oil field in the middle and late stages of development. The method can be executed by a device for determining the boundary of an ultra-deep strike-slip fault controlled reservoir. The device can be implemented in the form of hardware and / or software. The device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0038] S110. Determine the distribution of the fracture plane of the target layer fault zone in the mining area based on the seismic coherence body and reservoir inversion interpretation results.

[0039] Seismic coherence body can be the data obtained by detecting the mining area using coherence body technology. Among them, coherence body technology is a technology that uses the change of coherence value of seismic signals to describe the lateral heterogeneity of strata, lithology, etc., and then studies the spatial distribution of faults and microfractures, geological structural anomalies and the overall spatial distribution characteristics of lithology. The reservoir inversion interpretation results can be the results of determining the reservoir distribution in the mining area using seismic inversion technology. Among them, seismic inversion technology can be a method of imaging the spatial structure and physical properties of underground rock formations using surface seismic observation seismic data, with known geological laws and drilling and logging data as constraints. The distribution of fracture planes can be the distribution of fault zones in oil and gas reservoirs in the mining area. The mining area can be an area where oil and gas exist near the drilling. The target layer fault zone can be a fault zone in the oil and gas reservoir in the mining area.

[0040] When detecting the mining area, the coherence technology is used to detect the mining area, and based on the seismic coherence body obtained by the detection, it is determined whether there is a fault zone in the mining area and the distribution of the fault zone in the mining area.

[0041] In addition to using coherent volume technology to detect the mining area, seismic inversion technology is also used to detect the mining area to determine the distribution of the target layer in the mining area.

[0042] After determining the distribution of the target layer and the distribution of the fault zones in the mining area, the distribution of the fault zones in the target layer can be determined based on the distribution of the target layer and the distribution of the fault zones in the mining area, thereby determining the distribution of the fault plane.

[0043] By determining the fault plane distribution of the target layer fault zone in the mining area based on the seismic coherence body and reservoir inversion interpretation results, the determined fault plane distribution can be more accurate.

[0044] In an optional solution, the distribution of the fracture plane of the target layer fracture zone in the mining area is determined based on the seismic coherence volume and the reservoir inversion interpretation results, which may include steps A1-A3:

[0045] Step A1: Determine the horizontal distribution image of the fault zone in the mining area based on the seismic coherence volume.

[0046] Step A2: Determine the target layer distribution image in the mining area based on the reservoir inversion interpretation results.

[0047] Step A3: Determine the fracture plane distribution of the target layer fracture zone in the mining area according to the fracture zone horizontal distribution image and the target layer distribution image.

[0048] The horizontal distribution image of the fault zone can be a distribution image of the fault points in the mining area in the horizontal direction. The target layer distribution image can be the distribution of the target layer in the mining area. Among them, the target layer can be the distribution of oil and gas in the mining area.

[0049] After the mining area is detected by coherence technology and the seismic coherence body is obtained, in order to better facilitate the understanding of the staff, the horizontal distribution of the fault zone in the mining area can be drawn according to the seismic coherence body, thereby obtaining a horizontal distribution image of the fault zone.

[0050] Similarly, after obtaining the reservoir inversion interpretation results, the target layer distribution image in the mining area can be drawn based on the reservoir inversion interpretation results.

[0051] After obtaining the horizontal distribution image of the fault zone and the target layer distribution image, the target layer distribution image can be fitted with the horizontal distribution image of the fault zone to obtain the distribution of the fault plane.

[0052] S120. Determine vertical distances of drilling fault zones corresponding to different wells based on the distribution of fracture planes and single well drilling and completion data of at least two wells in the mining area.

[0053] The single well drilling and completion data can be the detection of a single well, so as to determine the formation pressure, formation temperature and single well production of the well. The vertical distance of the drilling fault zone can be the vertical distance between the bottom coordinate of the well and the fault zone closest to the bottom coordinate of the well.

[0054] After determining the planar distribution of the fault zone, the drilling trajectories of at least two wells can be determined through the single well drilling and completion data of at least two wells in the mining area, and then the specific locations of the wells in the mining area can be determined.

[0055] Based on the determined position and the distribution of the fracture plane, the positional relationship between the drilling trajectory of the well and the fracture zone can be determined, and then the fracture zone closest to the drilling trajectory can be determined, and the vertical distance between the fracture zone and the drilling fracture zone of the drilling trajectory can be determined.

[0056] By determining the vertical distances of the drilling fault zones corresponding to different wells based on the distribution of the fault plane and the single-well drilling and completion data of at least two wells in the mining area, the drilling trajectory determined by the single-well drilling and completion data is more consistent with the situation in the actual environment, thereby improving the accuracy of the vertical distance determination results of the fault zone and reducing the error of the system calculation.

[0057] S130. Determine the oil and gas production data of at least two wells in the production area based on the actual drilling dynamic and static data of the single well.

[0058] The dynamic and static data of a single well can be monitoring data of formation pressure, formation temperature, single well production, etc. during the oil well production process, including daily oil production, daily gas production, cumulative gas production in a stage, and cumulative oil production in a stage. The oil and gas production data can be daily oil production, daily gas production, cumulative gas production in a stage, and cumulative oil production in a stage.

[0059] Well logging is performed on at least two wells in the production area to obtain the actual drilling dynamic and static data of the single well corresponding to the well, and the daily oil production, daily gas production, cumulative gas production in a stage and cumulative oil production in a stage corresponding to the well are screened out from the actual drilling dynamic and static data of the single well as the oil and gas production data of the well.

[0060] By determining the oil and gas production data of at least two wells in the production area based on the actual drilling dynamic and static data of a single well, the oil and gas production data of the wells can be determined to be more in line with the actual situation, providing a certain guarantee for the accuracy of the system calculation results.

[0061] S140, determining a distance oil-gas relationship diagram group of different wells in the production area according to the vertical distance of the drilling fault zone and the oil and gas production data.

[0062] Among them, the distance oil and gas relationship diagram group includes the relationship between the vertical distance of the drilling fault zone and the oil and gas production data of the drilling.

[0063] After obtaining the vertical distances of the drilling fault zones of different wells and the corresponding oil and gas production data, the correspondence between the vertical distances of the drilling fault zones and the oil and gas production data can be determined, and a distance oil and gas relationship diagram group can be drawn according to the correspondence to represent the correspondence.

[0064] By determining a group of distance oil and gas relationship diagrams of different wells in the exploitation area based on the vertical distance of the drilling fault zone and the oil and gas production data, the correspondence between the vertical distance of the drilling fault zone and the oil and gas production data can be represented in a clearer manner, thereby making it easier for staff to understand the correspondence between the vertical distance of the drilling fault zone and the oil and gas production data corresponding to different wells in the exploitation area.

[0065] S150. Determine the reservoir-controlling boundary of ultra-deep strike-slip faults based on the distance oil-gas relationship diagram group.

[0066] After obtaining the oil and gas relationship map group, the vertical distance of the drilling fault zone of different wells and the corresponding relationship of oil and gas production data can be determined in the fault plane distribution, and the ultra-deep strike-slip fault control reservoir boundary can be determined based on the position area of ​​the corresponding relationship in the fault plane distribution.

[0067] According to the technical solution of the embodiment of the present invention, the distribution of the fracture plane of the target layer fault zone in the mining area is determined according to the seismic coherence body and the reservoir inversion interpretation results, so that the determined distribution of the fracture plane can be more accurate. By determining the vertical distance of the drilling fault zone corresponding to different wells according to the distribution of the fracture plane and the single well drilling and completion data of at least two wells in the mining area, the drilling trajectory determined by the single well drilling and completion data is more consistent with the situation in the real environment, thereby improving the accuracy of the vertical distance determination result of the fault zone, and then reducing the error of the system calculation. By determining the oil and gas production data of at least two wells in the mining area according to the actual drilling dynamic and static data of the single well, the oil and gas production data of the determined drilling can be more consistent with the real situation, providing a certain guarantee for the accuracy of the system calculation results. By determining the distance oil and gas relationship diagram group of different wells in the mining area according to the vertical distance of the drilling fault zone and the oil and gas production data, the corresponding relationship between the vertical distance of the drilling fault zone and the oil and gas production data can be expressed in a clearer way, so that the staff can more easily understand the corresponding relationship between the vertical distance of the drilling fault zone and the oil and gas production data corresponding to different wells in the mining area. By determining a group of distance oil and gas relationship diagrams of different wells in the exploitation area based on the vertical distance of the drilling fault zone and the oil and gas production data, the correspondence between the vertical distance of the drilling fault zone and the oil and gas production data can be represented in a clearer manner, thereby making it easier for staff to understand the correspondence between the vertical distance of the drilling fault zone and the oil and gas production data corresponding to different wells in the exploitation area.

[0068] Embodiment 2

[0069] Figure 2The present invention provides another flowchart of a method for determining the boundary of an ultra-deep strike-slip fault-controlled reservoir. Based on the above embodiments, this embodiment further optimizes the process of determining the vertical distance of the drilling fault zone corresponding to different wells according to the distribution of the fault plane and the single well drilling and completion data of at least two wells in the mining area in the above embodiments. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method for controlling reservoir boundaries by ultra-deep strike-slip faults in this embodiment may include the following steps:

[0070] S210. Determine the distribution of the fracture plane of the target layer fault zone in the mining area based on the seismic coherence body and reservoir inversion interpretation results.

[0071] S220. Determine the bottom hole coordinates corresponding to at least two wells according to the single well drilling and completion data of different wells in the mining area.

[0072] The bottom hole coordinates may be coordinate positions on a horizontal plane of the bottom hole of the well.

[0073] Based on the single well drilling and completion data of different wells in the mining area, the position of the well at the bottom of the well and the coordinates of the position on the horizontal plane can be determined.

[0074] S230, according to the bottom hole coordinates and the distribution of the fracture plane, determine the vertical distance of each bottom hole coordinate to the nearest target layer fracture zone as the vertical distance of the drilling fracture zone of the well corresponding to the bottom hole coordinate.

[0075] After obtaining the bottom hole coordinates corresponding to at least two wells, the fault zone closest to the bottom hole coordinates can be determined according to the distribution of the fracture plane, and then the vertical distance of the fault zone from the bottom hole coordinates can be determined as the vertical distance of the drilling fault zone corresponding to the bottom hole coordinates.

[0076] S240, determining the first single well daily oil production and the first single well daily gas production of the first well drilled in the production area according to the single well actual drilling dynamic and static data.

[0077] Among them, the drilling includes the first drilling and the second drilling, the first drilling is the other drilling other than the long-stop well, and the second drilling is the long-stop well. The oil and gas production data at least include the daily oil production of the first single well, the daily gas production of the first single well, the cumulative oil production of the second single well in a stage, and the cumulative gas production of the second single well in a stage.

[0078] S250, determining the second single well cumulative oil production and the second single well cumulative gas production in the second stage of the second well in the production area according to the actual drilling dynamic and static data of the single well.

[0079] S260, determining oil and gas production data according to the daily oil production of the first single well, the daily gas production of the first single well, the cumulative oil production of the second single well during the period, and the cumulative gas production of the second single well during the period.

[0080] A long-stop well may be an oil or gas well that has been shut down for more than one year or a well whose water content is too high and the oil and gas production is less than a preset value. The first well may be a well other than the long-stop well in the production area. The second well may be a long-stop well in the production area. The daily oil production of the first well may be the daily oil production of the first well. The daily production of the first well may be the daily gas production of the first well. The cumulative oil production of the second well in the stage may be the cumulative oil production of the long-stop well from the start of production to the current moment. The cumulative gas production of the second well in the stage may be the cumulative gas production of the long-stop well from the start of production to the current moment.

[0081] When determining the drilling oil and gas production data, different wells may have different calculation methods for the oil and gas production output, so different drilling oil and gas production data need to be determined for different wells.

[0082] For the first well, since the well is being produced or about to be produced, the daily production of the first well can be determined. For the second well, since the well is a long-stop well, the cumulative production of the second well can be determined. Thus, the first single well daily oil production and the first single well daily gas production of the first well, and the second single well stage cumulative oil production and the second single well stage cumulative gas production of the second well can be determined.

[0083] After obtaining the first single well daily oil production, the first single well daily gas production, the second single well stage cumulative oil production and the second single well stage cumulative gas production, the production of different wells in the production area can be determined, and then the oil and gas production data can be determined.

[0084] S270, determining a distance oil and gas relationship diagram group of different wells in the production area according to the vertical distance of the drilling fault zone and the oil and gas production data.

[0085] Among them, the distance oil and gas relationship diagram group includes the relationship between the vertical distance of the drilling fault zone and the oil and gas production data of the drilling.

[0086] In an optional solution, determining a distance oil-gas relationship diagram group of different wells in the production area according to the vertical distance of the drilling fault zone and the oil and gas production data may include steps B1-B5:

[0087] Step B1, determining a first distance oil-gas relationship diagram according to a first single well daily oil production corresponding to a first drilling well and a corresponding vertical distance of a drilling fault zone.

[0088] Step B2: determining a second distance oil-gas relationship diagram according to the first single well daily gas production corresponding to the first drilling well and the vertical distance of the corresponding drilling fault zone.

[0089] Step B3: determining a third distance oil-gas relationship diagram according to the second single well stage cumulative oil production corresponding to the second drilling well and the corresponding vertical distance of the drilling fault zone.

[0090] Step B4: determining a fourth distance oil-gas relationship diagram according to the second single well stage cumulative gas production corresponding to the second drilling well and the corresponding vertical distance of the drilling fault zone.

[0091] Step B5: determining a distance oil-gas relationship graph group according to the first distance oil-gas relationship graph, the second distance oil-gas relationship graph, the third distance oil-gas relationship graph and the fourth distance oil-gas relationship graph.

[0092] When determining the distance oil and gas relationship diagram group, since different wells determine different oil and gas production, different wells need to be determined separately.

[0093] Figure 3 This is a schematic diagram of a first distance oil-gas relationship diagram applicable to an embodiment of the present invention. Figure 3 , it is necessary to draw a first distance oil-gas relationship diagram according to the first single well daily oil production corresponding to the first drilling well and the corresponding vertical distance of the drilling fault zone.

[0094] Figure 4 This is a schematic diagram of a second distance oil-gas relationship diagram applicable to an embodiment of the present invention. Figure 4 , it is necessary to determine the second distance oil-gas relationship diagram according to the first single well daily gas production corresponding to the first drilling well and the vertical distance of the corresponding drilling fault zone.

[0095] Figure 5 Schematic diagram of the third distance oil-gas relationship diagram applicable to the embodiment of the present invention. Figure 5 , it is necessary to determine the third distance oil-gas relationship diagram based on the second single well stage cumulative oil production corresponding to the second drilling well and the corresponding vertical distance of the drilling fault zone.

[0096] Figure 6 Schematic diagram of the fourth distance oil-gas relationship diagram applicable to the embodiment of the present invention. Figure 6 , it is necessary to determine the fourth distance oil-gas relationship diagram based on the second single well stage cumulative gas production corresponding to the second drilling well and the corresponding vertical distance of the drilling fault zone.

[0097] The determined first distance oil-gas relationship graph, second distance oil-gas relationship graph, third distance oil-gas relationship graph and fourth distance oil-gas relationship graph are integrated to obtain a distance oil-gas relationship graph group.

[0098] S280. Determine the vertical depths of the bottom hole coordinates corresponding to the different wells according to the single well drilling and completion data of the different wells in the mining area.

[0099] The vertical depth can be the height difference between the bottom coordinate of the well and the ground.

[0100] When determining the bottom hole coordinates based on the single well drilling and completion data of different wells in the mining area, the vertical depth corresponding to the bottom hole coordinates can also be determined based on the single well drilling and completion data.

[0101] S290. Determine the reservoir-controlling boundary of ultra-deep strike-slip faults based on the distance oil-gas relationship diagram.

[0102] In an optional scheme, the ultra-deep strike-slip fault reservoir-controlling boundary is determined based on the distance oil-gas relationship graph group, including steps C1-C4:

[0103] Step C1: Determine at least one target oil and gas detection layer based on the unconformity surface in the production area.

[0104] Step C2: screening the distance oil-gas relationship graph group according to the vertical depth corresponding to at least one target oil-gas detection layer to obtain at least one target oil-gas relationship graph group.

[0105] Step C3: screening the distance oil-gas relationship graph group according to the vertical depth corresponding to the unconformity surface to obtain the unconformity surface oil-gas relationship graph group.

[0106] Step C4: Determine the reservoir-controlling boundary of the ultra-deep strike-slip fault based on at least one target oil-gas relationship graph group and an unconformity surface oil-gas relationship graph group.

[0107] The target oil and gas detection layer can be the stratum for determining the oil and gas relationship. The unconformity surface can be the surface where the sedimentary area was once uplifted, and then sedimentation occurred after sedimentation and / or denudation.

[0108] Figure 7 Schematic diagram of the ultra-deep strike-slip fault controlling the reservoir boundary used in the embodiments of the present invention. Figure 7 The horizontal solid line in the figure is the unconformity surface. The horizontal dotted line is the target oil and gas detection layer, and the position circled by the vertical dotted line is the boundary controlled by the ultra-deep strike-slip fault.

[0109] When determining the reservoir-controlling boundary of ultra-deep strike-slip faults based on the distance oil-gas relationship diagram group, it is necessary to determine the specific location of the unconformity surface in the mining area and divide at least one target oil and gas detection layer downward according to the specific location of the unconformity surface.

[0110] Since the vertical depths of the bottom hole coordinates of different drilling wells are different, the distance oil and gas relationship graph group can be screened according to the vertical depth of the divided target oil and gas detection layer, so as to obtain the target oil and gas relationship graph group on different target oil and gas detection layers.

[0111] According to the vertical depth corresponding to the unconformity surface, the distance oil-gas relationship diagram group is screened to obtain the unconformity surface oil-gas relationship diagram group, and the unconformity surface oil-gas relationship diagram group and the target oil-gas relationship diagram group are fitted to obtain the ultra-deep strike-slip fault controlled reservoir boundary.

[0112] According to the technical solution of the embodiment of the present invention, the distribution of the fracture plane of the target layer fault zone in the production area is determined based on the seismic coherence body and the reservoir inversion interpretation results. According to the single well drilling and completion data of different wells in the production area, the bottom hole coordinates corresponding to at least two wells are determined. According to the bottom hole coordinates and the distribution of the fracture plane, the vertical distance of each bottom hole coordinate from the nearest target layer fault zone is determined as the vertical distance of the drilling fault zone of the well corresponding to the bottom hole coordinate. According to the actual drilling dynamic and static data of the single well, the first single well daily oil production and the first single well daily gas production of the first well in the production area are determined. According to the actual drilling dynamic and static data of the single well, the second single well stage cumulative oil production and the second single well stage cumulative gas production of the second well in the production area are determined.
