摘要:

塔里木盆地H油田,整体采用超深水平井开发,近年套损现象呈增加趋势,给生产造成被动。针对该现状,实施多学科协作攻关,系统研究套损平面与纵向分布规律,重点开展物理与化学机理研究,明确提出油藏与钻井、测井、井下技术相结合的套损“防诊治”一体化研究思路。经实践证明,预测的套损隐患井与实际吻合程度及套损井恢复率均较高,成功探索了超深水平井套损对策技术,为其他类似油田提供了有益借鉴

Abstract:

The H Oil Field of the Tarim Basin is developed with the ultra deep horizontal well.In recent years,the phenomena of the casing failure has been increasing,resulting in the difficulties for the production.Pointing to the situation,effort is made to conduct multidisciplinary research on the damaged casing plane and the law of the longitudinal distribution.Research is also done on the physical and chemical mechanism in priority,the research clue of the casing damage "precaution,diagnose,treatment" technology is proposed by combining the reservoir engeneering,drilling,logging and down hole operation technology.The practice demonstrates that the forecasted casing damage wells are unanimous with the actual wells,and the recover ratio is high,which successfully seeks for the countermeasure technology for the casing failure in the ultra deep horizontal well,offeres the consults for other oilfields which have the analogous problems.

Key words: Tarim, horizontal well, casing failure, mechanism, precaution, diagnose and treatment
