用目前常规的测试资料解释方法很难对PG气田的非常规测试资料进行评价。在PG气田有限元数值试井方法,通过一系列网格划分的方式,使复杂的地质问题得以简化,从而能够实现复杂油藏动态变化特性的精细描述,达到解释PG气田的非常规测试的目的。
It is difficult to evaluate the unconventional test data of PG gas fields by using the conventional interpretation method of test data. In the PG gasfield numerical well test method, a series of gridding methods are adopted to simplify the complex geological problems so as to be able to describe the dynamic characteristics of complex reservoirs accurately and to achieve the purpose of explaining unconventional testing of PG gas fields .
