摘要
北12井是部署在松辽盆地长岭断陷的一口直探井,由于其目的层营城组下部整段裂缝发育,实际施工期间多次发生井漏,研究主要针对这几次井漏的处理过程进行详细探讨,总结出该区块后期应对裂缝性漏失的关键措施,以对长岭断陷后续钻井如何应对裂缝性漏失和有效处理裂缝性漏失具有重要的借鉴意义,同时该井的成功也为本区块其他井的施工提供了重要技术保障,能够有效促进该区块的勘探开发进程。
North 12 well is a direct exploration well deployed in the Changling Fault Depression of the Songliao Basin.Due to the development of fractures in the lower part of the Yingcheng Formation in its target layer,multiple well losses occurred during actual construction.This article mainly discusses the treatment process of these well losses in detail and summarizes the key measures to deal with fractured losses in the later stage of the block.It has important reference significance for the follow-up drilling of Changling Fault Depression on how to respond to and effectively deal with fractured leakage.At the same time,the success of this well also provides important technical support for the construction of other wells in this block,which can effectively promote the exploration and development process of this block.
