Wang Chen, Gao Xuezhen, Sun Chengyan, Wang Tingting, Zhao Wanchun

Abstract


In order to characterize the mechanical behavior of rock body damage evaluation and forming multiple fractures, in this paper in multiple fracturing, we have established rock body damage evaluation constitutive model, and given the point that the rock can bear secondary damage in multiple fracturing. Established the secondary damage evaluation model, and obtained the method for calculating the parameter of the crack in multiple fracturing. We have verified the model by an oil well in Jilin oilfield, the result has fitted well with the actual engineering.
Key words: Multiple fracturing; Damage evaluation; Secondary damage


Keywords


Multiple fracturing; Damage evaluation; Secondary damage
