抽汲井恢复资料校正

Correction for Build-up Data of Swabbing Well.

抽汲井压力恢复曲线存在关井早期压力数据丢失、井筒储集时间长等问题。本文从油井压裂后抽汲求产的井底压力分析出发 ,对压力恢复资料进行校正处理 ,得到了较好的恢复曲线 ,取得了准确的地层参数。

The problem of data loss during closure period of buildup curves and long time for well-bore storage in swabbing well is existed.From analyzing the down hole pressure to calculate flow rate,by correction and process for these data,a better build up curves and accurate formation parameters are achieved.
