探索川东地区石炭系气藏完井方法

An Exploration of the Well Completion Method for Carboniferous GasReservoir in East Sichuan Region

将川东石炭系气藏50口井的完井方法归纳为三类。本文从产层的单位厚度产量宏观分析出发,推荐出比较适合于该区的完井井身结构,并推荐改善尾管固井的措施。

Merging the completion methods of 50 gas wells in Carboniferous gas reservoirs in East Sichuan into three types, this paper recommends a casing program for well completion more suit-able to this region, starting from macroscopic analysis of the yield per unit thickness of the pay. In addition, the measure for improving the cement job quality of extension pipe are recommended.
