摘　　要：阿克莫木气田克孜勒苏群砂岩储层以长石岩屑砂岩及岩屑砂岩为主,储层物性较差,为低孔、低渗储层。自2013年以来,中国石油塔里木油田库车项目部已尝试在喀什凹陷阿克莫木构造上部署的两口水平开发井AK1-H3井和AK1-H6井运用选择性固井完井工艺技术,成功实现了油气层保护和提高了产量。以AK1-H6井127 mm选择性尾管固井工艺为例,介绍了这种技术的工艺原理、管串结构、技术措施以及现场的应用情况。通过该项工艺措施的运用,避免了井下产层污染,提高了单井产量。As a sandstone reservoir in Akmomu gasfield, Kizilsu Member is mainly dominated by both feldspathic litharenite and litharenite, and is characterized by poor physical properties with low porosity and permeability. Since 2013, the Kuche Project Department of Petro China Tarim Oilfield Company has applied some selective cementing and completion technologies to two horizontal development wells, AK1-H3 and AK1-H6, which are situated in Akmomu structure of Kashgar Depression. After that, this reservoir was successfully protected and its production increased. Taking127 mm selective drilling liner cementing technology for AK1-H6 well as an example, this paper presents its principle, string structure, technical measures and field application. This technology can prevent a payzone from contamination and increase production.
