在本文中,对消除井筒储存影响(续流)提出了一些新的试井解释方法。这些新方法都使用了同时测量层面流量和井筒压力的数据,并且证明了,如果没有井筒储存效应(单位响应或影响函数),能从层面流量和井筒压力数据的反褶积中获得地层动态。分析无储存效应的地层动态,可以确定正在测试的系统(油藏流动模式)以及估计它的油藏参数。本文也介绍了估计油藏参数的褶积法(径向多次流动法)以及反褶积和褶积法的一些综合例子。
In this paper, we propose some new well interpretation methods to eliminate the influence of wellbore storage (freewheeling). Both of these new methods use data that measure both layer flow and wellbore pressure at the same time and demonstrate that without wellbore storage effects (unit response or impact function), the formation dynamics can be derived from deconvolution of layer flow and borehole pressure data. Analyzing the stratum dynamics without storage effects can determine the system under test (reservoir flow pattern) and estimate its reservoir parameters. This article also presents some examples of convolution (radial multiple-flow method) and deconvolution and convolution methods that estimate reservoir parameters.
