摘要： 数值模拟是确定油气藏采收率的有效方法, 这一方法已广泛地应用来评价不同开发方式对不同类型、不同原油性质和储集层物性油藏最终采收率的影响, 并定量给出不同开发方式下油藏的最终采收率。然而, 很少采用数值方法评价气藏的采收率。通常是采用公式法、气藏驱动类型法或类比法等来确定气藏的废弃压力或采收率。现以数值模拟为研究手段, 以川西某气藏为研究对象, 对影响废弃压力和采收率因素进行敏感性评价。

Abstract: Numerical simulation as an effective method for determination of recovery of oil-gas reservoirs has been widely used to evaluatethe effects of different development schemes on the ultimate recovery of reservoirs with different types, different crude oil andpetrophysical properties. However, this method is scarcely used to estimate the recovery of a gas reservoir. Usually, formula method, gasreservoir driving type method and analogy method, etc., are used to determine the abandonment pressure or recovery. This paper, bymeans of numerical simulation study, evaluates the sensitivities of different factors affecting the abandonment pressure and recovery of agas reservoir in western Sichuan.

Key words: gas reservoir, abandonment pressure, recovery, numerical simulation
