Abstract
In-situ stress is the important basis for reservoir evaluation. Most of the in-situ stress solutions are based on well logging data and rock mechanics experiments. In fact, according to the actual geological condition, heterogeneity is an important factor affecting shale reservoir recovery. However, the effect of rock heterogeneity on stress is less considered. In this paper, taking well FY1 in block FY1 of Dongying depression as an example, the method of overall mechanical model analysis is used to analyze the in-situ stress of the study area, and the influence of rock heterogeneity on in-situ stress is studied, which reflects the true distribution of in-situ stress in shale reservoir. The research results show that, the minimum horizontal principal stress and the maximum horizontal principal stress increased slightly with the increase of depth, and the vertical stress increases gradually with depth, which is in direct proportion.
