大庆油田浅井地层测试工艺浅议

针对超浅井地层测试中因环空压力小、管柱重量轻、封隔器坐封难、开关井操作难的问题,分析了各测试工具的性能特点,设计出一套解决测试工具性能、管柱结构和工作制度的超浅井地层测试工艺技术。认为计算好封隔器所需钻压及油管、钻杆数量,保证封隔器坐封严密,减少开关井次数是测试成功的关键。

Discussion on Daqing Oilfield Low Test Layer Testing Process

Basing on the small annulus pressure,lightweight string,packer operation difficult of ultra-shallow well layer test,the paper analyzes all kinds of testing tools' features and designed a set of testing process technology to test tool performance,column structure,and working system.The author holds that the pressure of the packer and tubing required to drill;drill number are the key for testing.
