摘　　要：本文介绍了胜利油田欠平衡钻井完井液技术的室内研究 ,以及欠平衡钻井液在罗 15 1 11井、商 741平 1井、王平 1井的成功应用。三口井的应用证明 ,合理选择钻井完井液体系是实现欠平衡钻井成功的关键 ;在欠平衡钻井完井的施工中 ,采用合理的保护油气层措施 ,提高油井产能 ,是欠平衡钻井的宗旨。本文介绍的欠平衡钻井实践 ,为今后同一地区类似储层或其它地区类似储层的欠平衡钻井提供了宝贵的经验。Several drilling/completion fluids are formulated and developed for use in underbalanced drilling and their performance properties are evaluated in laboratory. These fluids are: a repeatly formable foam; polymer/MMH and polymer/BPS lightened water base fluids; saturated salt fluid with oil emulsified, etc. The drilling in every reservoir section(including two horizontal) in three wells at underbalanced conditions by using proper drilling in fluids is depicted in some detail with well description and productivity data presented.
