摘　　要：地层测试管柱中的漏失判别已成为不容忽视的问题。以往初终静液柱压力差法 (A -E法 )及二开井初与初开井末压力差法 (B2 -C1法 )都各有利弊 ,均不能准确判别漏失与否。在对以往测试资料的综合分析研究基础上 ,提出了B1法。将此三种方法结合应用 ,制定出适合目前测试需要的漏失判别标准。Judging leakage in well testing string has become a noticeable problem.The former methods which are the difference pressure between initial and final static liquid head (A-E method ) and the difference pressure between initial period of the second time open well and final period of the first time open well (B 2-C 1 method) have some advantages and disadvan tages respectively,that can not define whether the leak-off is exist or not.Based on comprehensive study and analysis to former testing data,the paper suggests the B 1 method.By synthetically utilizing this three kinds of methods,a criterion of leakage judgment which is suit for the need of well testing at present has been set up.
