地应力与岩石力学参数密切相关,在进行地应力计算时必须对岩石力学参数进行研究。本文首先分别应用动态法和静态法对岩石力学参数进行研究,得到了西峰地区岩石力学参数范围。在此基础上,综合利用该区块的测井、压裂资料,分别对该区块的构造应力系数、地应力、破裂压力进行了研究,并将理论破裂压力与实际施工破裂压力进行了比较,验证了利用动态法求地应力的准确性。
The in-situ stress is closely related to the rock mechanics parameters. Therefore, the rock mechanics parameters must be studied when calculating the geostress. In this paper, the dynamic mechanics and static methods are used to study the rock mechanics parameters respectively, and the range of rock mechanics parameters in Xifeng area is obtained. Based on this, the logging and fracturing data of this block are comprehensively used to study the tectonic stress coefficient, in-situ stress and rupture pressure of this block respectively, and compare the theoretical rupture pressure with the actual construction rupture pressure , Verified the accuracy of using dynamic method to find the ground stress.
