渤海M油田预防划出新井眼技术研究

Research on the prevention and demarcation of new boreholes in Bohai M Oilfield

渤海M油田钻井作业中由于需要进行预斜防碰,导致划出新井眼问题时有发生,严重影响了钻井成效。文章通过描述M油田划出新井眼的问题,在分析了问题产生原因的基础上,分别从钻具优选、钻进节点控制、倒划眼及下钻3个方面就预防划出新井眼的技术措施进行了重点阐述,从而彻底避免了油井划出新井眼问题的发生,应用前景广阔。

By describing the problem of new wellbore delineation in Bohai M Oilfield and analyzing the causes of the problem,the technical measures to prevent new wellbore delineation were emphasized from three aspects:drilling tool optimization,drilling node control,reverse drilling,and drilling down.This completely avoided the occurrence of new wellbore delineation in oil wells and has broad application prospects.
