摘要
采用预钻井方式开发的海上油气田,对水下钻井基盘钻井槽孔用完后增钻的调整井,可采用无基盘钻井方式作业。无基盘钻井技术在我国海上油气田开发中属首次应用。对无基盘钻井技术的特点,以及在东海平湖油气田应用该项技术时开眼钻井方式的选择、相应的技术措施作了详细阐述,并介绍了现场实施情况。无基盘钻井技术在平湖油气田的成功应用,对今后海上油气田开发中类似情况的解决具有借鉴和指导意义。
If pre-drilling mode was taken in an offshore oil development, PGB-free well drilling technology might be adopted for supplementary wells when the PGB slots were totally occupied. Such technology has been applied first in offshore oil and gas development in China. This paper describes in detail the characteristics of PGB-free drilling technology, selection of spud-in mode and related technical approach in application of the technology, as well as introduces the first practical implement case inCNOC＇ s Pinghu gas field in the East China Sea. It is hoped the experience and data acquired could be aguidance for a fterward application.
