提高低压易漏井固井质量研究

Improving cementing quality for the absorption wells of low pressure

主要阐述了目前应用于低压易漏井的主要固井技术:高强低密度水泥浆技术、前置低密度钻井液固井技术以及双级固井技术。在此基础上,综合分析了目前提高固井质量的主要措施。

This paper illustrates the cementing techniques for the absorption wells of low pressure,which include high strength and low density cement slurry,pre pumping low density drilling fluid and two-steps cementing. Then comprehensive analysis are carried out on the main measures of improving cementing quality.
