摘    要:本文针对目前变井储试井分析基本上仍停留于理论研究,还不能适应油气田生产需要的现状,建立了一个新的变井储试井模型,并在提出一种新的导数计算法基础上,研制出了适合各类变井储情况的驼峰型、台阶型和拟标准型典型曲线理论图版。结合一种新的变井储早期近似解解决了新图版应用中的多参数问题。最后分析了一个气井实例。

关 键 词:井筒储存  试井  试井解释  典型曲线拟合

Abstract:In view of the present situation that the current analysis of well-testing with changing wellbore storage (CWS) is still at the theoretical research stage, and that it cannot suit the needs of oil and gas oilfield production, this paper establishes a novel model for welltesting with changing wellbore storage, and develops a theoretical plate for typical curves,such as hump-type curve, step-type curve and pseudo-standard-type curve, which are suitable for various changing well storage on the basis of a new method of calculating pressure derivate. This paper, by using a new CWS early-time approximate ,solves the parameter problem in the applicatiin of this novel plate, and in the end, make an analysis of an actual gas well.
Keywords:Wellbore storage  Well-testing  Well test interpretation  Typical curve
