大套管修井施工方案分析

Plan Analysis for Workover Operation with Large Radius Case.

因生产需要 ,有时要对大套管井筒进行修井。但因套管内径大 ,采用试油设备修井时难度很大。经对DS1井实际修井资料进行分析 ,对大套管井的修井方案及其影响因素进行了总结 ,制定出了科学的技术措施 。

Sometimes, the work over operation must be done to large diameter cased bore hole for the need of production of the well. It is very diffcult to complete it with well testing and early production equipment for large diameter of case, By analyzing on field work-over data of DS1 well, the design and influenced factors to woke over of large cased wells have been summarized, a scientific technology measure have been conducted to get a reasonable results.
