Abstract
The in-stiu stress is the foundation of all kinds of engineering design,such as drilling and fracturing.It is very difficult to measure a lot of in-situ stress,and it is very important to establish an effective method to predict the stress field.Taking the SX deep formation as the research object,rock mechanical property evaluation experiments,paleomagnetism experi-ments and differential strain experiments were carried out to determine the rock mechanical parameter information of the regional formation and the geostress information of the well point.Combined with the geological structure information,the finite element simulation method was used to fuse multiple information,and the distribution nephogram and contour map of the regional geostress field were obtained by inversion.The simulation results showed that the three principal stresses in the region were mainly distributed in the range of 87.4～113.8,75.6～104.8 and 67.6～78.1 MPa.This method has small test volume and low cost,and can provide reliable basic data for mining engineering design.关键词
