基岩水井压裂增水机理分析

Analysis on the Mechanism of Water Increase by Fracturing in Bedrock Well

基岩地层压裂增水与岩层性质密切相关,不同岩性其力学性质及其裂隙构造不同,压裂机理与工艺方法就不同。根据基岩地下水岩层特点,结合水力压裂增水试验,着重分析了水力压裂的形成机制,探寻了不同岩层及其力学性质与压裂的关系。

The water increase by fracturing in the bedrock strata is closely related to rock properties. Because of different mechanical properties and fracture structure of each lithology,the fracturing mechanism and process methods are also different. According to the strata characteristics of bedrock groundwater and combined with the water increasing test of hydraulic fracturing,this article focuses on the analysis on the formation mechanism of hydraulic fracturing and explores the relationship between different layers as well as their mechanical properties and the fracturing.
