摘　　要：异常高压气藏往往存在着应力敏感，在开采过程中，随着累积采气量的增加，地层压力下降，孔隙度渗透率下降，逐渐影响到气田的开发与管理。本文从异常高压气藏的渗流机理入手，建立异常高压气藏应力敏感数值试井模型，采用差分法求解，得到了异常高压气藏开采的压差、压力导数典型曲线。有利于指导异常高压气藏开发方案的部署与优化，具有重要的理论意义和实际意义。Abnormally high pressure gas reservoir often is stress-sensitive, In the development process, with the increase of the cumulative gas produce, the formation pressure drop, Porosity and permeability decline gradually affect the gas field development and management. This paper from the filtration mechanism of abnormally high pressure gas reservoir with the Stress sensitive and establishing numerical well test mode. We solve the equation with differential method; we get the type curve of the pressure, the pressure derivative of the high-pressure gas reservoir, Guidance of the abnormally high pressure gas reservoir development and optimization of the deployment of the programmer, of great theoretical and practical significance.
