| 摘 要： | 近几年来，川西蓬莱镇组浅层气藏滚动勘探开发已形成规模。以蓬莱镇（Ｊ３ｐ）为主要目的层的井已达１５０余口。油气层保护技术有了很大的发展，取得了显著的经济效益和社会效益。油气层保护技术是一项系统工程，它涉及到钻井、完井、井下多种作业的多项环节。通过对蓬莱镇组浅层气藏地质特征和施工井资料分析，从完井方式、钻井工艺和钻井液体系及配方、钻井液性能、浸泡时间等多方面探讨如何更好地保护油气层、防止油气层伤害，提出了油气层段钻井施工中必须严格控制的几项重要指标及评定质量等级标准。

| Abstract: | A large scale shallow gas progressive exploration and development of Penglaizhen formation in West Sichuan has been done in recent years.The wells of taking Penglaizhen (J 3 p ) formatoon as main target zone are over 150. Through analysing geological characteristics and well drilling data of the shallow gas reservoirs,the hydrocarbon bearing interval safeguards are discussed in the respects of well completion ways,drilling technology,drilling fluid systems,drilling fluid formulation and performances,soak time etc. Several important indexes and quality evaluation standars being had to control in drilling operation of oil gas formation are proposed out. |
