摘要

对水平井筒应力分布进行了系统研究，采用FLAC3D 数值模拟软件建立三维模型，综合考虑地层构造应力和储层岩石力学影响，模拟研究了不同原岩构造应力差和水平段深度对水平井筒附近应力分布特征的影响，为计算水平井压裂破裂压力、裂缝起裂方位角、优化射孔等工程优化提供理论依据。

Abstract

This paper studies the stress distribution in horizontal wellbore systematically, utilizes the numerical simulation software FLAC3D to build 3D model; simulates the effect of tectonic stress differences of different source rocks and the depth of horizontal hole on stress distribution characteristics near horizontal wellbore by fully considering the formation tectonic stress and impact of reservoir rock mechanics; provides theoretic basis for calculating the horizontal well fracturing pressure, the fracture initiation azimuth and perforation engineering optimization.
