Abstract
In order to improve the fracturing success rate and modification effect of multistage and multiple cluster volume fracturing in horizontal wells. This paper studies the theoretical model of crustal stress change caused by a single artificial fracture and also considers the superposition distribution model of the stress field. With the increasing net stress, the decrease of Poisson’s ratio, the degree of interference between fractures will become more significant. When fractures reach a certain period, the interference degree remains unchanged. The emphasis of the study lies in the basis for the optimization method of forming active volumetric fractures and establishes a reservoir.
