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

Abstract:

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.
