Currently, the analytical flow models for multistage fractured horizontal well that describe seepage laws in unconventional tight oil and gas reservoirs mostly assume traditional idealized reservoir outer boundaries, which are closed, constant pressure, or infinite. However, these three types of boundaries cannot adapt to some actual situations engineering, boundary can show an elastic feature. To address this issue, based on engineering background shale development, conception condition is introduced first time, a novel physical model its mathematical wells with established. Through defining pseudo linearized, then, semi-analytical solution obtained by using Laplace transform. Finally, was applied analyze production data from parent reservoirs, suffer energy replenishment through fluid injection into infill wells. The results typical curve fitting improved our model. It largely increases accuracy forecast. Moreover, cover all boundaries. research greatly improves applicability All all, it provides important theoretical foundation mechanics dynamic analysis testing technologies development fields.
