摘要
渤海南部海域的B油田断层较发育,水平井着陆难度大且容易出现着陆失败的问题,通过对相关资料归纳总结,并结合断层对地层的影响以及与井轨迹的相互关系,梳理出水平井过断层着陆的下降盘着陆模式和上升盘着陆模式,并建立相应的导向方法。实践证明,该方法在渤海B油田水平井过断层着陆实施中成功率达100%,对油田后续地质导向工作具有一定的借鉴意义。
The faults of B oilfield located in southern Bohai Sea are relatively developed,and therefore,the horizontal well landing is not easy and prone to landing failure.Based on the analysis of relevant data,combined with the influence of fault on formation and the relationship between well trajectory,two fault-crossing landing modes and their corresponding mode-oriented methods have been established.The application results indicate by using these methods the success rate in Bohai B Oilfield is up to 100%,which is good for the follow-up geo-steering.
