国内尾管固井完井技术现状

Development Status of Liner Cementing and Liner Completion Technology in China

介绍了小井眼固井、尾管先期防砂完井、尾管回接固井、旋转尾管固井、膨胀套管完井和尾管钻井等6种新兴的尾管技术。分析了特殊卡瓦式悬挂器、尾管回接装置和膨胀式悬挂器等3大类尾管完井工具研究现状。建议在尾管完井中采用特殊尾管和新兴的完井方式,并采用多手段提高尾管固井质量。指出尾管悬挂器应向多功能化、简单化和可靠性方向发展。

Six types of liner completion technologies were introduced,such as slim hole cementing,liner advanced sand control completion,liner tieback cementing,rotating liner cementing,expandable casing completion and liner drilling.The development status of 3 types of liner completion tools were analyzed,which included special slip type hangers,liner tieback assemblies and expandable liner hanger.Moreover,the proposals were provided that the special liners and new completions can be used in the liner completion technology,more than one means were used to improve the quality of liner cementing,the development direction of liner hanger with multi-functional,simplicity and reliability was pointed out.
