| 摘 要： | 低渗透储层具有应力敏感性、启动压力等极其复杂的渗流特征，不宜采用衰竭方式进行开发。也不宜采用大压差进行生产。本文通过一个实例验证得出，无论是否考虑应力敏感，随着初始产能的增加，稳产期和稳产期采收率都会下降，只是，考虑应力敏感比不考虑应力敏感时下降的幅度更大。并且，考虑到应力敏感效应，气井的配产不宜过大，否则会影响稳产期采出程度。

| Abstract: | Due to produced gases,reservoir pressure declines,and permeability and productivity of wells decrease correspondingly,which is called stress sensibility.The flow characterist-ics in low-permeability reservoirs are extremely complex due to their stress-sensitivity and starting pressure,etc.it can not be developed by depletion and also not be produced thr-ough using high pressure difference.This paper describes a result from an example,wheth-er consider stress sensibility or not,with the increasing of initial... |
