Integrated Geology-Engineering Early Warning Technologies for Lost Circulation of Fractured Reservoirs in Bohai Oilfield

  • 摘要:

    为了解决渤海油田裂缝性油藏钻井过程中因断层、裂缝引起的井下漏失等问题,提出了地质工程一体化井漏预警技术。在叠后地震大中尺度断层刻画的基础上,通过滤波、断裂增强等特殊处理,进行属性优选及多属性融合,精细刻画中小尺度裂缝,建立了多尺度裂缝三维空间分布模型,设计井眼轨道时避开漏层,进行钻前风险提示,指导钻井作业采取相应的防漏堵漏措施;钻进过程中开展井漏风险随钻跟踪,实时调整并反馈井漏风险预测结果,及时优化井眼轨道,形成了随钻过程中漏层动态避钻技术,以充分保障钻井作业安全,降低钻井成本。钻前风险预测、钻进中井漏跟踪及随钻井眼轨迹实时优化等技术在旅大X油田应用后,实现了一趟钻规避断层漏失段。地质工程一体化井漏预警技术能够降低钻井风险,保障裂缝性油藏的钻井安全,为渤海油田增储上产提供了技术支撑。
