摘　　要：中1H井是塔中卡塔克1区块的一口侧钻短半径水平井,先后采用了多种较为先进的生产工艺,如锻铣开窗技术、定向侧钻技术、小井眼短半径水平井技术、欠平衡钻井技术、高钙盐钻井液体系的推广应用等,施工程序复杂。历时142.75 d完成了这口技术密集的评价井,试油见到了良好的油气显示,社会效益、经济效益显著。Well Middle 1H is a sidetracking horizontal well with short radius sited in the middle area of Tarim,Katac block 1.Several kinds of advanced techniques were used in this well such as forge milling side opening technology,directional sidetracking technology,small hole short radius horizontal well drilling technology,underbalance drilling technology and spreading application of high calcium salt mud system.The operation process is very complicated.After 142.75 days′ hard working of several technicians,the well is completed.Oil and gas show is good after oil test and the social and economic benefit is obvious.
