摘要: 以云南陆良、保山盆地第三系浅层气田为例,结合国内外浅层气田的开发经验,探讨浅层气田的开发规律,以指导同类气田的开发。浅层气田一般气藏规模小,气柱高度小;产层疏松,大部分气藏为有水气藏;生产时气藏无水生产时间短、稳产时间短,气井容易出水、出砂,其开发规律明显区别于中深层整装构造型气藏。针对陆良、保山浅层气田生产表现的“三低”(低单井日产水平、低采气速率、低采出程度),气井见水快,井筒容易积液,产层容易出砂,出水大则出砂也大等特点,提出以下对策: (1)依据多井小压差原则,进一步完善井网,避免频繁激动气井; (2)严格按规定压差生产,及时确定气井“三稳定”的最佳工作制度,生产中; (3)尽量减少或杜绝井口气量调节,更不能轻易关井;(4)一旦发生气井水淹,尽快采取措施,避免造成井底或地层的严重污染,给复产带来困难; (5)加强气田生产测井、试井、产能测试,取全取准各项资料,及时进行动态分析与动态监测,对生产中出现的问题做到早发现、早解决。从而保证气田平稳、正常开采。

Abstract: Shallow gas formation production law is probed by taking the shallow Tertiary gas formation production as example, as well as combining the experiences of shallow gas formation production from home and abroad, to guide the production correspondingly. Gener-ally, the shallow gas formations are of smaller size, lower gas col-umn, loose pay zone and water production; in production, the reservoirs have a very shorttime inwithoutwater production and stable production, and they are easy to produce water and sands, the
production law clearly differs frommiddle-deepwhole package structure gas reservoirs. Aimed at“the three-low characteristics”(lowdaily output, lowgas production rate and lowgas recovery), quick-er water production easier well bore liquids accumulation and sands production, the principle is put forward to improve well pattern and avoid continuously stimulating gas well.
