Prediction method, equipment and system for distribution law of shale oil and gas reservoir bedding fractures

Abstract

The invention provides a method, a system, a computer device and a computer-readable storage medium for predicting the distribution law of shale oil-gas reservoir bedding fractures, and relates to the technical field of oil-gas exploration. The method includes identifying the developmental section of the lamina fractures in a single well shale oil and gas reservoir; evaluating the development intensity of the identified shale oil and gas reservoir lamina fractures in a single well, and obtaining the development intensity of the lamella fractures in a single well; Clarify the main controlling factors of bedding fractures, and establish the relationship information between them and the development intensity of bedding fractures of a single well; predict the bedding fractures of shale oil and gas reservoirs according to the development intensity of bedding fractures of the single well and the relationship information distribution rule. The invention can predict the distribution law of shale oil and gas reservoir shale fractures, provide geological basis for prediction of shale oil and gas sweet spot and reservoir fracturing, thereby reducing the risk cost of shale oil and gas exploration, and has a certain value for guiding the production and development of shale oil and gas. Significance.

Description

technical field [0001] The present invention relates to the technical field of oil and gas exploration, in particular to the exploration technology of shale oil and gas reservoirs, specifically a method, system, computer equipment and computer-readable storage medium for predicting the distribution law of shale oil and gas reservoirs . Background technique [0002] The lamellation fracture mainly refers to the fracture formed during the deposition and diagenesis process along or parallel to the bedding surface. The matrix physical properties of shale oil and gas reservoirs are poor, and lamellar fractures are generally developed. Lamellar fractures are important storage spaces and seepage channels for shale oil and gas, which affect the accumulation, enrichment, single well productivity and development effect of shale oil and gas. The distribution of shale fractures is an important geological basis for the exploration and development of shale oil and gas, and is of great si...
