2014年8月2日凌晨,由中国石油川庆钻探工程公司川西钻探公司川庆70601队承钻的塔中超深水平井ZG13-3H井,历经7个月施工,安全钻至井深7 849m顺利完钻,创我国陆上最深水平井完钻新纪录。ZG13-3H井是中国石油塔里木油田公司部署在塔中北斜坡40号构造带上的1口开发超深水平井。根据塔中区块钻井作业过程高井控风险和大型交叉作业的特点,川庆70601队强化工艺安全分析,提前编制超深水平井的作业技术规程和安全预案。
Early in the morning of August 2, 2014, the Tazhong ultra-deep horizontal well ZG13-3H drilled by the Chuanqing 70601 team of Chuanxi Drilling Company of Chuanqing Drilling Engineering Company of China Petroleum Company completed the construction in 7 months and the safety drill was completed to a well depth of 7,849m , Creating the deepest horizontal well in land drilling a new record in China. ZG13-3H well is an ultra-deep horizontal well developed by PetroChina Tarim Oilfield Company at No. 40 Tazhong North Slope. According to the risk control of high-well control and the characteristics of large-scale cross-operation during block drilling operation in Block Tazhong, ChuanQing 70601 Team intensified the process safety analysis and worked out the technical specifications and safety preplan of the ultra-deep horizontal well in advance.
