钻井工程设计优化与应用

为适应油田勘探开发要求,按照钻井工程设计优化原则,在借鉴国内外一些成功经验的基础上,提出了应用不同钻井条件的套管、钻头尺寸组合优化设计方案,并根据油气井类型、地层特点和储层性质,开展了钻井液优化设计和固井完井优化设计研究,同时将部分钻井新技术应用于油田勘探开发,取得了良好的应用效果。

Drilling engineering design optimization and application

In order to meet the requirements of oilfield explora- tion and development,on the basis of principles of drilling engineering design optimization,using domeslic and inter- national successful experiences for reference,the opti- mized design on casing and bit size under different drilling conditions is provided.According to well types,forma- tion characteristics and reservoir quality,the research on drilling fluid design,cementing and completion optimiza- tion has been developed.At the same time,some new drilling techniques have been put into practice and a- chieved great effect.
