摘　　要：干扰试井设计参数选择误差较大导致干扰时间估算不准确是干扰试井测试失败的主要原因。针对影响干扰试井设计的各影响因素,统计整理了近几年胜利油区干扰试井测试资料,分析了压力计分辨率、激动量、有效厚度、渗透率参数及非均质性对干扰试井设计结果的影响,经过统计回归分析,得到了测井渗透率与干扰试井解释井间渗透率之间的相关性,得出了干扰试井设计参数选取中的一般规律和综合考虑各种影响因素的方法,实例应用取得较好效果。Inaccurate interference time estimates due to the interference well testing design parameter selection error is the main reason for interfering test fails.For the influencing factors that affect the interference test design,well testing data ofwells in recentyears are sorted out statistically,the impact of the pressure gauge resolution,the amount of excitement,the effective thickness,the permeability and sub-homogeneous to interference well testing design are analyzed.Through statistics,regression and analysis,the relativity of logging permeability and interference well testing permeability is acquired and the general laws of interference testing design parameters are selected and the method of comprehensive consideration of various factors affecting is obtained.Applied examples are obtained better results.
