Abstract

The invention discloses a ground stress data prediction method, comprising: constructing a three-dimensional geological frame model of the target area according to the three-dimensional seismic interpretation horizon data of the target area and fault data of the target area; Combine pre-stack rock mechanics parameter inversion to generate a 3D rock mechanics parameter data volume in the target area; integrate the rock mechanics measured data in the target area, the rock mechanics logging interpretation results of a single well in the target area, and the 3D rock mechanics parameter data volume in the target area , to obtain a three-dimensional rock mechanics model; based on the three-dimensional rock mechanics model, a three-dimensional finite element numerical simulation calculation is performed to obtain three-dimensional geostress data in the target area. This method establishes a high-precision three-dimensional rock mechanics model, improves the accuracy of numerical simulation of in-situ stress, and predicts the three-dimensional in-situ stress field more accurately.

Description

Technical field [0001] The present invention relates to the field of geological exploration techniques, and more particularly to a ground stress data prediction method, a device, a storage medium, and an electronic device. Background technique [0002] The ground stress research is an important job in oil and gas exploration and development, widely used in geological structural analysis, gathered gas transfer aggregation, reservoir natural crack formation and distribution, drilling completion, hydraulic fracture, well network deployment, sleeve deformation, Exploration and development areas such as sand forecasting. [0003] The ground stress research method can be divided into three categories: one is the stress measurement method, including hydraulic fracturing method, well wall collapse method, differential variable analysis method, etc., this type of method is directly measured by the field test or rock heart directly measure the stress size or direction of the rock. However,...
