Embodiment Construction

[0020] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0021] like figure 1 as shown, figure 1 It is a flow chart of a specific embodiment of the sandy conglomerate comprehensive geological modeling method of the present invention.

[0022] In step 101, basic data is prepared and loaded. Through the analysis and sorting of drilling, seismic, logging and stratigraphic correlation information, the accurate basic data of the geological model is screened out. In a specific embodiment, by summarizing and analyzing previous geological knowledge, data including oilfield well positions, well trajectories, stratigraphic stratification data, logging curves, seismic structural interpretation data, and lithology curves are collected. In addition, various test data (such as: well test and oil test), fluid prop...

Abstract

The invention provides a glutenite comprehensive geologic modeling method. The method comprises step1, performing analysis and arrangement on drilling well, earthquake, logging and stratigraphic correlation information to screen geologic model basic data; step2, building a stratum and tectonic framework model through single-well fine stratigraphic correlation, fine earthquake explanation and fine inter-bed and fracture system description; step3, recognizing and determining lithologic characteristics; step4, building a sedimentary facies model; step5, building an attribute model through a pore penetration model. By the aid of the method, the lithology identification accuracy is improved, and rapid division of the sedimentary facies is achieved through man-machine interaction.

Description

technical field [0001] The invention relates to the technical field of oil field development, in particular to a sandy conglomerate comprehensive geological modeling method. Background technique [0002] Reservoir geological modeling is an effective technical means to characterize reservoir heterogeneity in reservoir research or reservoir prediction. Oilfield development practice has proved that the reliability of reservoir numerical simulation results largely depends on the reliability of reservoir geological model provided by reservoir description. [0003] Glutenite reservoirs are mainly near-shore subaqueous fan deposits formed by the slump and re-transportation of sandy gravel sediments. Glutenite bodies have the characteristics of near provenance, large thickness, and rapid phase change, showing various depositional types and complex spatial distribution. , poor reservoir stratification, and serious heterogeneity reservoir characteristics. Based on the above charact...
