| 中文摘要:针对渤海油田L井存在异常高压、三压力窗口窄、在高压区域存在断层等作业难点，通过应用精细控压地面设备，控制合理的钻井参数，形成精细控压钻井技术，降低了在L井钻井过程中发生喷漏同层的风险，实现了溢流早预防，早发现，早解决。结合控压钻进、接立柱、起下钻等安全作业措施，成功实施L井侧钻井眼作业，为渤海油田异常高压地层的勘探开发奠定了技术基础。 |

| Abstract:In view of abnormal high pressure， the narrow three-pressure window and faults in the high-pressure zone in Well L in Bohai Oilfield， fine pressure-control drilling technology was developed through use of fine pressure control surface equipment and proper control of drilling parameters to reduce the risk of both leakage and blowout in the same layer during well drilling， and achieved early prevention， early discovery and early settlement of overflow. In combination with safe operation measures such as pressure-controlled drilling， connecting drill pipe stands， and tripping of drilling strings， Well L was successfully side-tracked， laying a technical foundation for the exploration and development of the abnormal high-pressure area in Bohai Oilfield. |
