摘要: 本文内容:(1)给出了恢复试井确定总导压能力系数θ方法,见方程(16).其优点是不需要依赖压降试井数据,而直接利用恢复试井本身的资料即可;(2)给出了压降试井确定窜流系数λ的一个方法,见方程(22);(3)给出了恢复试井确定窜流系数λ的两个方法,见方程(24)和(36).此二方法的优点在于:它们不需要压降试井数据,而只用恢复试井本身的资料,这就比已有的某些方法更加有用;(4)为检验方法进行了实例计算.

Abstract: This paper gives following results.(1) A method is presented to deter-mine total pressure transmissibitity θby pressure build-up data from a well.Its advantage is that only pressure build-up data are required without pressure drawdown testing data,(2) A mehtod is presented to determine cross flow coefficient λ from pressuredrawdown data;(3) Two methods are presented to determine the crossflow coefficient λfrom pressure build-up data.Their advantages are that only data of build-upwell testing is required without pressure drawdown testing data.Thus they are better than the methods now in use.practical examples are given to demonstrate these methods.
