摘要
随着各大油田相继进入开发中后期,小井眼完井技术主要用于难采储量油田,或复杂油气藏地层条件下的水平井、大斜度井中,但涉及不深,技术还很不成熟。目前,国内小井眼完井试油工具主要以封隔器、桥塞和循环阀类3种类型为主。其中,封隔器一般与循环阀类配合使用,也可单独使用。塔里木油田分公司根据小井眼侧钻水平井完井施工要求,设计了小井眼配套完井管柱工艺,应用于45口井,成功率为95.6%,应用效果较好。
Slim-hole well completion technology is majorly used in the oilfields with reserves difficult to be recovered or in the horizontal wells and highly deviated wells with complex oil-gas formation condition.Now in China,slim-hole completed well testing tools have three types：packer,bridge plug and circulation valves.The packer is used together with circulation valves in general,but also used alone sometimes.Slim-hole-oriented completion pipe string technology has been designed out to satisfy the completion demand of slim-hole sidetrack horizontal wells in Tarim Oilfield.This technology has been applied to 45 wells with a good application result.
