摘要
开江区块地处四川东部高陡构造群边缘,地质情况复杂,在完钻的29口井中,多数井均遇井漏、井塌、高压、高含硫、多断层等复杂情况。文中分析开江地区地质特征,提出小间隙井身结构和小间隙小眼井井身结构的设计方案,并从钻井工艺技术角度等方面进行论证。
Kaijiang block is located on the edge of high dip structure group in east Sichuan,
where formation is complex in geology of 29 completed wells,most were involved in complex
problems, such as lost circulation,high pressure,high sulphur content,and many faults.This paper
analyses geologic features in Kaijing area and presents the small clearnce casing program design
and that for slim-holes.It has also been rectified in the aspect of drilling technology.
