摘　　要：低渗透储集层在开采过程中,随着流体的采出而使地层有效应力升高,从而导致储集层岩石发生变形,渗透率随之发生变化,呈现出应力敏感的特征。低渗透储层是否存在较强的应力敏感性,对此国内外研究尚未达成共识。针对这一问题对应力敏感性实验的影响因素以及评价方法进行归纳总结,并提出符合实际油藏开发的实验规范和评价准则。In the mining process of the low-permeability reservoir,with the recovery of the fluid,the effective stress will increase,resulting the deformation of the reservoir and the change of the permeability.This phenomenon called ＂stress sensitivity＂.It has been studied at home and abroad,but there is still no consensus whether the stress sensitivity is high or not in the low-permeability reservoir.For this reason,the influencing factors and the evaluation method of stress sensitivity experiments are summarized in this paper,and experimental reservoir and evaluation criteria more coincident to the actual reservoir development are put forward.
