摘要

介绍了针对制约涩北气田高效开发的防砂技术难题,通过综合采用“稳、固、防”等配套工艺,筛选出了较适合涩北气田高泥质粉细砂岩气藏防砂的高压一次充填防砂和纤维复合压裂防砂工艺。截止2005年10月该项工艺已推广应用到47口井,大多数防砂井日产气量有了明显的提高,单井日产气量平均增加40%以上,防砂有效期最长已达3年以上,满足了粉细砂岩气藏防砂和进一步提高气井单井产能的开发需要。

Abstract

This paper introduces sand-control  troubles that restrict efficient exploitation of Sebei Gas Field (SGF).Through  comprehensive utilizations of sand-stacilization, sand-consolidation and sand |control technologies, the HRWP and fibered Frac-Pack technologies are showed t he optimization solutions for sand-control jobs of high-clay fine siltstone in  SGF. These two technologies have been implemented on 47 wells until now. Most o f wells after sand-control job, with the average gas-production increase of 40  percents ,and the maximum effective period up to 3 years. These data show that  these two technologies can meet the sand-control demand of the fine-siltstone reservoir  and the demand of further promoting well production.
