钻孔水压致裂法测地应力的探讨

Discussion on Geostationary Stress Induced by Hydraulic Fracturing

水压致裂法测量地应力具有测量深度很大的优点,在地质工程中应用广泛,为解决传统水压致裂法的不足,一些学者提出了三维地应力测量理论,采用最小主应力破坏准则进行水压致裂法三维地应力测量,对地质条件比较复杂的地区可以用该方法进行测量,但水压致裂三维地应力测量方法还需改进和完善。传统的水压致裂法理论和三维地应力测量理论各有优缺点。

The measurement of in-situ stress by hydraulic fracturing has the advantages of great depth of measurement, and it is widely used in geological engineering. In order to solve the shortcomings of the tradition- al hydraulic fractur/ng method, some scholars have proposed three-dimensional stress measurement theory, using the minimum principal stress failure criterion for hydro-static fracturing three-dimensional in-situ stress measure- ment.The method can be measured by the method in which the geological conditions are more complicated, but the method of measuring the three-dimensional stress of hydraulic fracturing needs to be improved and perfected. The traditional theory of hydro-cracking and three-dimensional stress testing have their own advantages and dis- advantages.
