双孔复合储层中井底压力的求解分析

针对双孔复合储层模型,研究了两种内边界条件下、变流率问题的无因次井底压力的Laplace 空间解,在深入剖析了解的结构和相互联系的基础上,找出了它与常见的复合、双孔、均质储层井底压力间的相互关系,并简要地引导了相应的应用。该研究无疑是对试井分析理论的一种完善,其试井分析软件更具有深远的应用价值。

SOLUTION ANALYSIS OF THE BOTTOM PRESSURE IN DUAL POROUS COMPOSITE RESERVOIR

This paper studies the solution of dimensionless bottom ressure in LaplacOspace about variable rate under two inner oundary conditions. On the base of the structure and relation of the solutions analysis , the relation of bottompressure is found out in common composite reservoir , dual porous reservoir and homogeneous reservoir , and corresponding application of the solution is simply introduced. The research makes well test theory perfect , and makes well test software have more application value.
