完井是高温超低压气田开发的关键环节。文章针对崖城13-1气田调整井高温、超低压、井深大、水平位移大的完井难点,通过对储层保护、完井液技术、完井管柱和连续油管诱喷工艺为一体的综合性研究及成功应用,形成了具有南海西部油田特点的高温超低压井的完井系列技术,为类似海上和陆地高温超低压井的田完井提供借鉴。
Completion is the key to the development of high temperature and ultra-low pressure gas fields. In this paper, aiming at the difficulties of well completion in Yacheng 13-1 gas field, such as high temperature, ultra-low pressure, well depth and large horizontal displacement, the reservoir protection, completion fluid technology, completion string and coiled tubing decoying process are integrated Comprehensive research and successful application have resulted in the completion series of HTHP wells with the characteristics of western South China Sea oilfield, which can be used as a reference for the field completion similar to offshore and terrestrial UHT wells.
