宁夏固原采卤井施工技术
|
摘要
结合宁夏固原采卤井的地质概况、盐井技术参数及要求、钻探设备、钻井工艺等方面对采卤井施工进行了介绍,重点阐述了钻井液、固井、水平井对接施工等关键工艺技术措施,并列举了施工中出现的粘土侵、含石膏泥岩缩径垮塌、大斜度井段沉砂等突出问题,并就其处理方法进行了分析探讨,总结了采卤井施工经验。
Based on geological survey,salt well technical parameters and requirements,drilling equipments,drilling technology and other aspects in the brine well in Guyuan of Ningxia,this paper introduces the brine well construction,focuses on the key technical measures of drilling fluid,cementing and butt construction,etc.and lists the outstanding issues appeared in the construction,such as clay mixing into drilling fluid,gypsum-containing shale necking collapse and sand setting in high angle wells segment,the processing methods are analyzed and the experiences and lessons of brine well construction are summarized.
