摘要： 致密低渗气藏开发过程中储集层存在应力敏感,不同的试验方法评价结果差异很大。用3种不同的试验方法分别对大牛地致密低渗气藏5个储集层岩心进行应力敏感性试验评价,通过对试验结果和气藏实际生产过程中应力变化规律的综合分析,选定了比较能够反映致密低渗气藏开采过程中储集层应力敏感变化特征的两种试验评价方法。

Abstract: There exist big differences in studied result with different test methods for dense reservoir rock in low permeability gas pool is sensitive to the stress. In this paper, three different test methods are applied to five core samples from Daniudi gas pool, respectively, and their stress changes between the test results and real production performances are analyzed in detail. Finally, two of three methods are selected, which are better reflecting the stress sensitivity variation rules.

Key words: dense reservoir rock, low permeability, stress sensitivity, overburden pressure, fluid pressure
