[0002] As the exploration and development of carbonate oil and gas reservoirs deepens, the Ming River has seriously restricted the success rate of exploration. The exploration experience of Tarim Oilfield over the years shows that most of the first and second-level river channels obviously control the development of water systems, and the third-level and lower river channels control the development of reservoirs. Therefore, the depiction of the Ming River channel is an important support for exploration.

[0003] In the actual application process, on the one hand, the paleo-geomorphology of the late sedimentation of the research target layer that geologists are concerned about is mostly unconformity surface, which generally undergoes weathering and erosion. In this case, the paleo-geomorphology restored by seismic data and residual thickness method alone will have more or less deviations, and it is difficult to find a suitable maximum flooding surface as a standard layer due to the influence of erosion, which makes the calculation relatively complicated; on the other hand, although it is relatively direct to use the current structure to depict the river channel, it still needs to be picked up manually, and the efficiency and accuracy will inevitably be limited by the level. Therefore, how to avoid the errors caused by erosion and human intervention and further improve the efficiency and accuracy of Minghe river channel depiction has become the key to exploration.

[0027] Embodiment 1

[0028] Figure 1 A flow chart of a method for determining the grade distribution of a carbonate rock river channel is provided for the first embodiment of the present invention. This embodiment can be applied to accurately identify carbonate rock river channels, thereby determining the grade distribution of carbonate rock river channels. The method can be executed by a device for determining the grade distribution of carbonate rock river channels. 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:

[0029] S110, determining the spatial distribution of the target layer in the target detection area based on the drilling data, logging data, seismic data and sequence stratigraphic analysis results of at least one well in the target detection area.

[0030] Drilling data can be a series of data obtained during the drilling process, including but not limited to drilling time, mud and the location of the emptying lost section. Logging data can be data measured by instruments after drilling is completed, including but not limited to logging curves, imaging logging and P-wave logging curves. Seismic data can be data obtained by monitoring earthquakes in the target detection area, including but not limited to earthquake magnitude, earthquake depth, earthquake location, earthquake time and earthquake waveform. The target detection area can be the spatial range of the spatial distribution of the monitoring target layer. The results of sequence stratigraphic analysis can be a study of the sedimentary sequence of the region, single well and connected wells based on drilling, logging and seismic data to clarify the distribution law of sedimentary phases. The spatial distribution of the target layer can be the three-dimensional distribution of the target layer in the target detection area, including but not limited to depth, width and height. The target layer can be an oil and gas reservoir in the target detection area.

[0031] By using the drilling data, logging data, seismic data and sequence stratigraphic analysis results of different wells in the target monitoring area, the length, width and depth of the target layer in the target monitoring area can be determined, thereby determining the spatial distribution of the target layer in the target detection area.

[0032] In an optional solution, determining the spatial distribution of the target layer in the target detection area based on drilling data, logging data, seismic data and sequence stratigraphic analysis results of at least one well in the target detection area may include steps A1-A3:

[0033] Step A1: Determine the maximum flooding surface, the top isochronous reflection surface and the bottom formation reflection surface of the target layer based on the drilling data, logging data, seismic data and sequence stratigraphic analysis results of at least one well in the target detection area.

[0034] Step A2: Determine the seismic profile information of the target detection area according to the maximum flooding surface, the top isochronous reflection surface and the bottom stratum reflection surface of the target layer.

[0035] Step A3: Obtain the spatial distribution of the target layer based on the seismic profile information.

[0036] The maximum flooding surface may be the interface formed when the maximum transgression in the sequence can reach the position. The isochronous reflection surface may be the response of the equipotential surface on the seismic profile. The isochronous surface may be the boundary between any two stratigraphic biles. The top isochronous reflection surface may be the isochronous reflection surface at the top of the target layer. The bottom stratigraphic reflection surface may be the isochronous reflection surface at the bottom of the target layer. The seismic profile information may be the calibration result of the seismic profile, including position information, depth information, width information, etc.

[0037] When determining the spatial distribution of the target layer, it is necessary to determine the maximum flooding surface, the top isochronous reflection surface and the bottom formation reflection surface of the target layer based on the drilling data, logging data, seismic data and sequence stratigraphic analysis results of different wells in the target monitoring area, and then determine the boundary of the target layer.

[0038] By using the maximum flooding surface, top isochronous reflection surface and bottom stratum reflection surface of the target layer, the seismic profile in the target monitoring area is calibrated to obtain the seismic profile information in the target monitoring area, thereby determining the specific positions of the maximum flooding surface, the top isochronous reflection surface and the bottom stratum reflection surface on the seismic profile, and using the determined specific positions to determine the spatial distribution of the target layer in the target monitoring area.

[0039] S120. Determine the sedimentary phase development distribution map based on the spatial distribution of the target layer.

[0040] The sedimentary facies development distribution map can be the topography of carbonate rocks formed and remaining during the geological history period.

[0041] After determining the spatial distribution of the target layer, the topography of the carbonate rock can be marked according to the spatial distribution of the target layer, thereby drawing a sedimentary phase development distribution map.

[0042] In an optional solution, determining the sedimentary facies development distribution map according to the spatial distribution of the target layer may include steps B1-B5:

[0043] Step B1, calibrating the maximum flooding surface of the target layer according to the seismic data, and determining the first spatial distribution of the maximum flooding surface; wherein the first spatial distribution is the distribution of the maximum flooding surface in three-dimensional space;

[0044] Step B2: calibrate the top isochronous reflection surface of the target layer according to the seismic data to determine the second spatial distribution of the top isochronous reflection surface; wherein the second spatial distribution is the distribution of the top isochronous reflection surface in three-dimensional space;

[0045] Step B3: calibrate the bottom stratum reflection surface of the target layer according to the seismic data to determine the third spatial distribution of the bottom stratum reflection surface; wherein the third spatial distribution is the distribution of the bottom stratum reflection surface in three-dimensional space;

[0046] Step B4, determining micro paleo-geomorphology restoration data according to the first spatial distribution, the second spatial distribution, the third spatial distribution and the drilling data of at least one well in the target detection area;

[0047] Step B5: Determine the sedimentary phase development distribution map based on the micro-paleomorphological restoration data.

[0048] The first spatial distribution can be the distribution of the maximum flooding surface in the target monitoring area in three-dimensional space. The second spatial distribution can be the distribution of the top isochronous reflection surface in the target monitoring area in three-dimensional space. The third spatial distribution can be the distribution of the bottom stratum reflection surface in the target monitoring area in three-dimensional space.

[0049] By using seismic data, the maximum flooding surface, the top isochronous reflection surface and the bottom stratum reflection surface of the target layer are interpreted in three-dimensional space, and the distribution of the large flooding surface, the top isochronous reflection surface and the bottom stratum reflection surface of the target layer in three-dimensional space can be determined, including but not limited to length, width and depth, so as to obtain the first spatial distribution, the second spatial distribution and the third spatial distribution respectively. After determining the first spatial distribution, the second spatial distribution and the third spatial distribution, the location of the Minghe River channel in the first spatial distribution, the second spatial distribution and the third spatial distribution can be determined according to the drilling data of at least one well in the target detection area, so as to determine the micro paleo-geomorphology restoration data, and finally, according to the micro paleo-geomorphology restoration data, the sedimentary phase development distribution map can be drawn.

[0050] The Minghe river channel can be the river channel exposed on the upper surface of carbonate rocks. The micro-paleomorphological restoration data can be the specific data used to construct the sedimentary phase development distribution map.

[0051] In an optional solution, determining micro paleo-geomorphology restoration data according to the first spatial distribution, the second spatial distribution, the third spatial distribution and the drilling data of at least one well in the target detection area may include steps C1-C2:

[0052] Step C1, according to the drilling data of at least one well in the target detection area, determine the target layer layer data corresponding to at least one well and the Minghe drilling data.

[0053] Step C2: Determine the micro paleo-geomorphology restoration data according to the first spatial distribution, the second spatial distribution, the third spatial distribution, the target layer stratification data and the Minghe drilling data.

[0054] The target layer stratification data can be used for the wells that have been drilled, and the target layer system is clarified through logging and other data. The Minghe drilling data can be the stratification data of the target layer in the wells that drilled into the Minghe River.

[0055] Since not every well in the target monitoring area can reach the carbonate rock river, it is necessary to determine each well in the target monitoring area to obtain the corresponding target layer stratification data and the river encounter data. At this time, the wells that drilled to the carbonate rock river in the target monitoring area can be determined, and according to the corresponding target layer stratification data and the river encounter data, the first spatial distribution, the second spatial distribution and the third spatial distribution are corrected to determine the micro paleo-geomorphology restoration data.

[0056] In an optional solution, determining the sedimentary phase development distribution map based on micro-paleomorphological restoration data may include steps D1-D3:

[0057] Step D1: construct an initial sedimentary phase development distribution map based on micro-paleomorphological restoration data.

[0058] Step D2: According to the initial trend surface of the target layer and the drilling data, the initial sedimentary phase development distribution map is fitted to determine the target trend surface.

[0059] Step D3: Process the initial sedimentary facies development distribution map according to the target trend surface to obtain a sedimentary facies development distribution map.

[0060] The initial sedimentary facies development distribution map may be a sedimentary facies development distribution map directly drawn from micro-paleomorphological restoration data. The initial trend surface may be a trend surface determined based on the initial sedimentary facies development distribution map. The target trend surface may be a trend surface obtained by smoothing the initial regional surface.

[0061] After obtaining the micro-paleomorphology restoration data and constructing the initial sedimentary facies development distribution map, since there is a certain fluctuation at the top of the initial sedimentary facies development distribution map, it is necessary to use the initial trend surface and drilling data to perform multiple fittings on the top of the initial sedimentary facies development distribution map, so as to reduce the fluctuations and obtain the target trend surface. The initial sedimentary facies development distribution map is subtracted from the target trend surface to obtain the sedimentary facies development distribution map.

[0062] S130. Determine the level distribution of carbonate river channels in the target detection area based on the sedimentary phase development distribution map and drilling data.

[0063] The grade distribution can be used to describe the graded distribution of different open river channels of carbonate rocks in the target monitoring area.

[0064] After obtaining the sedimentary facies development distribution map, the sedimentary facies development distribution map and drilling data can be used to determine the spatial distribution of different Minghe channels, and then determine the levels of different Minghe channels, and then determine the level distribution of carbonate Minghe channels in the target detection area.

[0065] According to the technical solution of the embodiment of the present invention, the spatial distribution of the target layer in the target detection area is determined based on the drilling data, logging data, seismic data and sequence stratigraphic analysis results of at least one well in the target detection area; the sedimentary phase development distribution map is determined based on the spatial distribution of the target layer; the level distribution of the carbonate Minghe river channel in the target detection area is determined based on the sedimentary phase development distribution map and the drilling data, thereby realizing the hierarchical characterization of the Minghe river channel, improving production efficiency and providing support for the optimization of carbonate karst reservoirs.

[0066] Embodiment 2

[0067] Figure 2 The present invention provides a flowchart of another method for determining the level distribution of carbonate rock river channels. Based on the above embodiment, this embodiment further optimizes the process of determining the level distribution of carbonate rock river channels in the target detection area according to the sedimentary phase development distribution map and drilling data in the above embodiment. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method for determining the level distribution of a carbonate rock river channel in this embodiment may include the following steps:

[0068] S210, determining the spatial distribution of the target layer in the target detection area based on the drilling data, logging data, seismic data and sequence stratigraphic analysis results of at least one well in the target detection area.

[0069] S220. Determine the sedimentary phase development distribution map based on the spatial distribution of the target layer.

[0070] S230, the sedimentary phase development distribution map is enlarged to a preset multiple, and the interval contour lines are marked to obtain an interval contour line map.

[0071] The preset multiple may be a multiple determined based on historical experience. The interval contour line may be a contour line used to represent terrain height or other attributes. The interval contour line map may be an image obtained by annotating the sedimentary facies development distribution map using interval contour lines.

[0072] Since the size of the sedimentary facies development distribution map is often small, it is necessary to enlarge the sedimentary facies development distribution map so that it can be accurately marked with interval contour lines to obtain an interval contour line map.

[0073] S240. Determine the level distribution of carbonate river channels in the target detection area based on the drilling data and the interval contour map.

[0074] According to the drilling data and the interval contour map, different bright river channels of the carbonate rocks in the target detection area can be marked in the interval contour map, and then the outlines of different bright river channels can be determined, and then the level distribution of the bright river channels of the carbonate rocks in the target detection area can be determined.

[0075] In an optional solution, the level distribution of the carbonate river channel in the target detection area can be determined based on the drilling data and the interval contour map, which may include steps E1-E3:

[0076] Step E1: Determine the spatial distribution of the carbonate rock river channel based on the drilling data and the interval contour map.

[0077] Step E2: Determine the channel interval contour lines corresponding to the channel spatial distribution according to the channel spatial distribution and the interval contour line map.

[0078] Step E3: Determine the level distribution of the carbonate rock river channels in the target detection area based on the channel interval contour lines and the target trend surface.

[0079] The spatial distribution of the river channel may be the distribution of the river channel of a bright river in three-dimensional space. The interval contour lines of the river channel may be interval contour lines that coincide with the contour of the river channel.

[0080] After obtaining the drilling data and interval contour map, the drilling data can be used to determine the wells that have been drilled into the Ming River, and the spatial distribution of the carbonate rock Ming River channel can be determined based on the drilling data and interval contour map of the wells that have been drilled into the Ming River. Based on the spatial distribution of the channel and the interval contour map, the interval contour lines of the channel that overlap with the Ming River channel outline can be determined, and finally the classification of different Ming River channels can be determined based on the height changes of the target trend surface, the width and depth of the Ming River channel, and finally the level distribution of the carbonate rock Ming River channel in the target detection area can be determined.

[0081] According to the technical solution of the embodiment of the present invention, the sedimentary phase development distribution map is magnified to a preset multiple, and the interval contour lines are marked to obtain an interval contour line map, and the level distribution of the carbonate river channel in the target detection area is determined based on the drilling data and the interval contour line map. The determination process of the carbonate river channel classification can be clarified, thereby ensuring the accuracy of the determination result.
