[0029] Embodiment 1

[0030] Figure 1 A flowchart of a method for displaying the spatial distribution of oil and gas reservoirs is provided for the first embodiment of the present invention. This embodiment is applicable to displaying the spatial distribution of deep or ultra-deep carbonate oil and gas reservoirs. Figure 1 As shown, the method can be performed by an oil and gas reservoir spatial distribution display device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method specifically comprises the following steps:

[0031] S110, spatially locate, volumetrically determine and quantitatively process the carbonate reservoir to determine spatial distribution information of the carbonate reservoir.

[0032] Among them, carbonate rock can refer to the general term for rocks composed of carbonate minerals formed by sedimentation, mainly limestone and dolomite. Reservoir can refer to pores that can be used as a space for storing oil and gas and are not distributed in layers but form irregular combinations within and between layers. Reservoir can refer to a reservoir in carbonate rock. Spatial distribution information can include spatial distribution position information and spatial distribution porosity information.

[0033] Specifically, the seismic sensitivity attribute of the carbonate reservoir is determined based on the well logging data, and the seismic sensitivity attribute parameter of the core corresponding to the critical porosity (such as 2%) between the reservoir and the non-reservoir is obtained according to the seismic sensitivity attribute, and the seismic sensitivity attribute parameter is used as the seismic sensitivity attribute threshold corresponding to the carbonate reservoir, and the carbonate reservoir is spatially located based on the seismic sensitivity attribute threshold of the carbonate reservoir. The forward model is re-established according to the seismic sensitivity attribute, stratigraphic structure, and well logging information of the carbonate reservoir, and the correction coefficient is determined according to the difference between the simulated seismic response result and the actual model volume. The carbonate reservoir is volume-fixed based on the correction coefficient to obtain the carbonate reservoir volume close to the real value. The porosity data body of the carbonate reservoir is obtained by the methods of prestack inversion, rock physics analysis, and rock physics modeling, and the spatial distribution information of the porosity information of the carbonate reservoir is determined. Based on the spatial position distribution information of the carbonate reservoir, the volume after volume fixing, and the spatial distribution information of the porosity information, a 3D visualization carving map of holes and caves is obtained, and the 3D visualization carving map of holes and caves is determined as the spatial distribution information of the carbonate reservoir.

[0034] S120, detecting and predicting the spatial distribution of the fluid in the reservoir, and determining the spatial distribution information of the fluid in the reservoir.

[0035] The fluid in the reservoir may be a general term for gas and liquid, for example, water, natural gas or oil.

[0036] Specifically, the fluid properties are qualitatively detected based on the AVO (Amplitude variation with offset) attribute and seismic dispersion attribute of the reservoir under seismic waves. The constraints of macroscopic geochemical conditions such as the filling height of the reservoir, the tracing of the oil and gas migration path, and the detection of the plane filling strength of the reservoir determined by the precise tracing technology of the whole process of oil and gas accumulation are used to ensure accurate fluid property detection results. The prestack seismic longitudinal and transverse wave joint inversion is carried out on the fluid in the reservoir to obtain the longitudinal wave impedance, transverse wave impedance and density body. Then, the quantitative interpretation standard is established through detailed rock physics modeling, and the distribution range of the reservoir is quantitatively obtained using the inversion results. The spatial distribution range of the fluid is constrained according to the distribution range of the reservoir, and the distribution range of the reservoir is coupled with the fluid detection to determine the spatial distribution information of the fluid in the reservoir.

[0037] S130. Determine the spatial distribution information of carbonate rock fractures and cavities based on the spatial distribution information of the reservoir and the spatial distribution information of carbonate rock fractures.

[0038] Among them, carbonate rock fractures and caves can refer to reservoir spaces composed of caves, cracks and dissolution pores of varying sizes.

[0039] Specifically, the seismic attributes related to carbonate rock fractures are used to select thresholds to determine the spatial distribution information of carbonate rock fractures. Based on the spatial distribution information of the reservoir body and the spatial distribution information of carbonate rock fractures, the spatial distribution information of the reservoir body and the spatial distribution information of carbonate rock fractures are positionally fused to determine the spatial distribution information of carbonate rock fractures and cavities.

[0040] Exemplarily, S130 may include: dividing the seismic sensitivity attribute values ​​of carbonate rock fractures based on the seismic sensitivity attribute thresholds of the fractures to determine the spatial distribution information of the carbonate rock fractures; and positionally fusing the spatial distribution information of the reservoir and the spatial distribution information of the fractures to obtain the fused spatial distribution information of carbonate rock fractures and cavities.

[0041] Specifically, the seismic sensitivity attribute value interval corresponding to the carbonate rock fracture is determined based on the seismic sensitivity attribute threshold of the fracture. The spatial distribution information of the carbonate rock fracture is obtained according to the seismic sensitivity attribute value interval corresponding to the carbonate rock fracture. Based on the spatial distribution information of the reservoir, a pore-cavity three-dimensional data body corresponding to the spatial distribution of the reservoir with the three-dimensional spatial coordinates (x, y, z) as the position function is obtained. Based on the spatial distribution information of the carbonate rock fracture, a fracture three-dimensional data body corresponding to the spatial distribution of the carbonate rock fracture with the three-dimensional spatial coordinates (x, y, z) as the position function is obtained. The fracture three-dimensional data body is positionally fused with the pore-cavity three-dimensional data body to obtain a three-dimensional data body corresponding to the spatial distribution of carbonate rock fractures and caves. The spatial distribution information of carbonate rock fractures and caves is obtained based on the three-dimensional data body. It should be noted that the three-dimensional data body refers to a data set with the three-dimensional spatial coordinates (x, y, z) as the position function.

[0042] S140. Based on the spatial distribution information of fractures and cavities and the spatial distribution information of fluids, the spatial distribution information of carbonate oil and gas reservoirs is rendered and displayed.

[0043] Specifically, based on the spatial distribution information of fractures and holes and the spatial distribution information of fluids, a three-dimensional fracture data body corresponding to the spatial distribution information of fractures and holes and a three-dimensional fluid data body corresponding to the spatial distribution information of fluids are obtained, the three-dimensional fracture data body and the three-dimensional fluid data body are positionally fused, the spatial distribution information of carbonate oil and gas reservoirs is determined, the fused three-dimensional data body is three-dimensionally carved, and different rendering methods are selected to render and display the spatial distribution information of carbonate oil and gas reservoirs, thereby obtaining a three-dimensional sculptured image of the reservoir and oil and gas reservoir in the carbonate rock.

[0044] Exemplarily, S140 may include: based on the fluid spatial distribution information, determining the spatial distribution information of carbonate oil and gas reservoirs that meets the preset distribution conditions; based on the first rendering method, rendering the spatial distribution information of fractures and caves, and displaying the reservoir spatial distribution in a three-dimensional visualization map; based on a second rendering method different from the first rendering method, rendering the spatial distribution information of the oil and gas reservoirs, and displaying the spatial distribution of the oil and gas reservoirs in the three-dimensional visualization map.

[0045] Among them, the preset distribution conditions may refer to the pre-set calibration conditions that the spatial distribution of carbonate oil and gas reservoirs needs to meet. Exemplarily, the preset distribution conditions may include: the spatial distribution of oil and gas reservoirs conforms to the calibration law of oil and gas accumulation paths in the horizontal direction, and conforms to the natural differentiation law of fluids and the calibration of well data in the vertical direction. The first rendering method and the second rendering method refer to two different display styles, so as to clearly distinguish the spatial distribution of reservoirs and the spatial distribution of oil and gas reservoirs. For example, the first rendering method may refer to marking the spatial distribution information of fractures and caves in black and white. The second rendering method may refer to marking the spatial distribution information of carbonate oil and gas reservoirs in color.

[0046] Specifically, based on the fluid spatial distribution information, the fluid three-dimensional data body corresponding to the fluid spatial distribution information is obtained, the fracture-hole three-dimensional data body is positionally fused with the fluid three-dimensional data body, and the carbonate oil and gas reservoir spatial distribution information that meets the preset distribution conditions is determined according to the position coordinates in the fused three-dimensional data body, and the fused three-dimensional data body is three-dimensionally engraved, and different rendering methods are used to render and display the carbonate oil and gas reservoir spatial distribution information. Figure 2 As shown in Figure 1, the spatial distribution information of fractures and caves is rendered using grayscale values ​​at different depths, and the spatial distribution of reservoirs is displayed in a three-dimensional visualization diagram; Figure 3 As shown, different colors are used to render the spatial distribution information of oil and gas reservoirs, and the spatial distribution of oil and gas reservoirs is displayed in the three-dimensional visualization map. Therefore, the spatial distribution of oil and gas reservoirs in the reservoir can be clearly viewed in the three-dimensional visualization map, realizing the visualization and transparency of the spatial distribution of carbonate oil and gas reservoirs, making the drilling target clearer and more specific.

[0047] The technical solution of the embodiment of the present invention can obtain a reservoir volume close to the actual value and realize quantitative characterization of the reservoir by spatially positioning, volume determination and quantitative processing of the carbonate reservoir, and determining the spatial distribution information of the carbonate reservoir; detect and predict the spatial distribution of the fluid in the reservoir to obtain more accurate fluid property prediction results and fluid spatial distribution information; determine the spatial distribution information of carbonate fractures and holes based on the spatial distribution information of the reservoir and the spatial distribution information of carbonate fractures; render and display the spatial distribution information of carbonate oil and gas reservoirs based on the spatial distribution information of fractures and holes and the spatial distribution information of fluids, thereby obtaining a three-dimensional visualized spatial distribution of oil and gas reservoirs, realizing three-dimensional transparent characterization and quantitative characterization of deep carbonate oil and gas reservoirs, and further realizing reservoir carving on the basis of carbonate reservoir carving, making the drilling target more specific and clear.

[0048] Embodiment 2

[0049] Figure 4 This is a flow chart of a method for displaying the spatial distribution of oil and gas reservoirs provided in Example 2 of the present invention. Based on the above embodiments, this embodiment optimizes the step of "spatial positioning, volume determination and quantitative processing of carbonate reservoirs to determine spatial distribution information of carbonate reservoirs". Explanations of terms that are the same or corresponding to the above embodiments are not repeated here.

[0050] See also Figure 4 Another method for displaying the spatial distribution of oil and gas reservoirs provided in this embodiment specifically includes the following steps:

[0051] S210: Determine a seismic sensitivity attribute threshold of the reservoir, and divide the seismic sensitivity attribute values ​​of the carbonate rock based on the seismic sensitivity attribute threshold to determine initial distribution position information of the carbonate rock reservoir.

[0052] Among them, the seismic sensitive attribute may refer to the rock physical attribute that can clearly distinguish the reservoir from the non-reservoir. It should be noted that the reservoir may refer to the reservoir layer, and the non-reservoir layer may refer to the non-reservoir layer. The reservoir layer may refer to the rock layer with a core porosity greater than 2%. The non-reservoir layer may refer to the rock layer with a core porosity less than or equal to 2%.

[0053] Specifically, the seismic sensitivity attributes of the reservoir are determined based on the logging data, the seismic sensitivity attribute value corresponding to the rock layer with a porosity of 2% is used as the seismic sensitivity attribute threshold of the reservoir, the seismic sensitivity attribute values ​​of the carbonate rock are divided based on the seismic sensitivity attribute threshold, and the reservoir is spatially located based on the seismic sensitivity attribute threshold of the reservoir to determine the initial distribution position information of the carbonate rock reservoir.

[0054] Exemplarily, "determining the seismic sensitivity attribute threshold of the reservoir" in S210 may include: obtaining the seismic sensitivity parameter value of the reservoir under each reflection type, wherein the reflection types include: beaded reflection, flaky reflection and messy reflection; comparing the seismic sensitivity parameter values ​​under all reflection types to determine the seismic sensitivity attribute threshold of the reservoir.

[0055] Specifically, the seismic, well logging, and mud logging information are integrated to determine the different types of reservoir sensitive seismic parameters corresponding to the beaded reflection, sheet reflection, and chaotic reflection of the reservoir under seismic waves. The seismic sensitivity parameter values ​​under all reflection types are compared, and the seismic sensitivity attribute value that can distinguish between reservoirs and non-reservoirs is determined as the seismic sensitivity attribute threshold of the reservoir.

[0056] S220, determining a volume correction coefficient of the reservoir, and correcting the volume of the reservoir under the initial distribution position information based on the volume correction coefficient to obtain spatial distribution position information of the carbonate reservoir.

[0057] The volume correction factor may refer to the scaling ratio between the seismic representation of the reservoir obtained by seismic wave reflection and the actual reservoir volume.

[0058] Specifically, the forward model is re-established according to the seismic attributes, stratigraphic structure and logging information of the reservoir, the correction coefficient is determined according to the difference between the simulated seismic response results and the actual model volume, the volume of the reservoir under the initial distribution position information is corrected based on the volume correction coefficient to obtain a reservoir volume close to the actual value, and the spatial distribution position information of the carbonate reservoir is obtained based on the spatial positioning of the reservoir and the corrected reservoir volume.

[0059] S230, quantifying the porosity of the carbonate reservoir to determine spatially distributed porosity information of the carbonate reservoir.

[0060] Among them, porosity can refer to the ratio of the sum of the volumes of all pore spaces in a rock sample to the volume of the rock sample, which is called the total porosity of the rock and is expressed as a percentage.

[0061] Specifically, based on the address data of the carbonate reservoir, the porosity data body corresponding to the reservoir is obtained by using prestack inversion, rock physics analysis, rock physics modeling and other methods. The porosity data body is analyzed, and the carbonate reservoir is quantified based on the analysis results to determine the spatial distribution porosity information of the carbonate reservoir.

[0062] Exemplarily, S230 may include: performing reservoir parameter inversion based on post-stack seismic data to obtain reservoir parameter inversion results at each location of the carbonate reservoir; based on the conversion relationship between porosity and inversion parameters, converting the reservoir parameter inversion results at each location into corresponding porosity to obtain spatially distributed porosity information.

[0063] Specifically, based on the wave impedance, transverse and longitudinal wave velocities, porosity, resistivity and other parameters corresponding to the reservoir in the post-stack seismic data, the reservoir parameters are subjected to band-limited inversion or broadband inversion to obtain the reservoir parameter inversion results at each position of the carbonate reservoir; the inversion results are analyzed to obtain the original distribution of parameters such as wave impedance in the underground, and based on the conversion relationship between porosity and inversion parameters, the reservoir parameter inversion results at each position are converted into corresponding porosity to obtain spatially distributed porosity information.

[0064] S240: Detect and predict the spatial distribution of the fluid in the reservoir to determine the spatial distribution information of the fluid in the reservoir.

[0065] S250: Determine the spatial distribution information of carbonate rock fractures and cavities based on the spatial distribution information of the reservoir and the spatial distribution information of carbonate rock fractures.

[0066] S260: Based on the spatial distribution information of fractures and cavities and the spatial distribution information of fluids, the spatial distribution information of carbonate oil and gas reservoirs is rendered and displayed.

[0067] The technical solution of the embodiment of the present invention determines the seismic sensitivity attribute threshold of the reservoir, divides the seismic sensitivity attribute value of the carbonate rock based on the seismic sensitivity attribute threshold, obtains the spatial distribution result of the carbonate reservoir by using the seismic sensitivity attribute and seismic inversion, and determines the initial distribution position information of the carbonate reservoir; determines the volume correction coefficient of the reservoir, and corrects the volume of the reservoir under the initial distribution position information based on the volume correction coefficient to obtain the spatial distribution position information of the carbonate reservoir that is close to the real value; performs porosity quantification processing on the carbonate reservoir to determine the spatial distribution porosity information of the carbonate reservoir, thereby realizing quantitative characterization of the spatial distribution of the carbonate reservoir by using porosity data.
