粘土矿物在页岩储层当中非常丰富,然而,页岩储层很容易受到损害,其中最主要的两个因素就是应力敏感性和流体敏感性损害。当耦合现象发生于以上两者之中时,渗透率在储层当中将明显下降,这将导致页岩气在开发过程中工程质量的明显下降。在非常规油气资源重要性越来越突出的背景下,本文通过实验,对流体损害对页岩储层应力敏感性的影响进行了深入分析,希望对我国非常规尤其资源的开发起到促进作用。 Clay minerals are abundant in shale reservoirs. However, shale reservoirs are highly susceptible to damage. Two of the most important of these are stress-sensitivity and fluid-sensitivity damage. When the coupling occurs in the above two cases, the permeability will obviously decrease in the reservoir, which will lead to the obvious decline of the quality of shale gas during the development process. Under the background that the importance of unconventional oil and gas resources is more and more prominent, this paper analyzes the influence of fluid damage on the stress sensitivity of shale reservoirs through experiments, hoping to promote the development of unconventional and special resources in our country .
