Analysis of transient pressure behavior in linear composite reservoir with partially connected faults
摘要
Abstract
The application of presently existing models of well testing analysis to actual well testing data with partially connected fault boundary usually resulted in unsatisfactory consequences.Therefore,a concept of "boundary skin" is proposed in which the partially connected fault is considered as an infinite thin boundary skin and a new well testing model for partially connected fault in a two-zone,linear composite reservoir is established.Fourier and Laplace transformations are used to calculate and obtain the solution,and to plot the responding typical curves of well bottom pressure.It shows that large boundary skin leads to the upward of curve.When the boundary skin is large enough,the partially connected fault is characteristic of close fault.If the ratio of thickness and ratio of mobility become larger,the typical curve demonstrates a character of stable pressure boundary.It reveals that the smaller the pressure coefficient ratio,the greater the storage capacity of the zone Ⅱ,and the lower the corresponding pressure and pressure derivative curve position.关键词
