用干扰试井方法研究鄂尔多斯盆地上古生界地层有效连通井距

Researching on Effective Communicated Well Spacing in Erdos Upper Paleozoic Strata with Interference Test Method

鄂尔多斯盆地上古生界地层是一个范围宽广的低丰度气田区,自从上世纪90年代逐步投入开发以来,合理的开发井距一直是困扰开发方案设计的关键问题。从苏14井区干扰试井设计入手,介绍了开展干扰试井研究时采取的方法,以及成果和经验。由于执行了缜密的干扰试井设计思路,采取了切实、合理的资料录取和分析方法,紧密跟踪、调整现场测试进程,使干扰试井研究工作获得成功,为这一地区开发方案设计时确定临界连通井距,提供了明确无误的标尺。

Erdos Upper Paleozoic strata is a broad range of low abundance gas field area,since the 90's of the last century gradual putting into development,reasonable developing well spacing is always the key problem plagued designing development plan.Starting from the interference testing design of Su 14 well area,the method,achievement and experience of interference test are introduced.Due to the careful implementation of the interference test design,taking the practical,reasonable data acquisition and analysis method,closely tracking the adjustment process,field test,the research work of the interference test is successful,which provides the unmistakable scale to determine the critical communicated well spacing designed in development program.
