Mud Loss Control while Drilling with Oil Base Drilling Fluid

  • 摘要: 针对在用油基钻井液钻进页岩气井水平段时井漏事故常有发生,造成严重的经济损失,研制了一种A型堵漏材料,对其进行了粒径分析,优选了最佳粒径范围,并在油基钻井液中评价了其堵漏性能。实验结果显示,A型堵漏剂的配伍性好,分散性好,吸油膨胀率高,抗150℃高温,砂床渗透侵入深度为1.0 cm,几乎是零滤失;与同类产品进行了对比,堵漏性能优于其他同类产品,具有好的防渗堵漏和裂缝堵漏效果;正向驱替压力为13 MPa,反向突破压力为1.2 MPa,承压强度高,反向驱替压力低,能够解决油基钻井液的渗透性漏失问题;A型堵漏剂与其他堵漏材料复配时能够有效解决1~3 mm裂缝漏失问题。形成了一套油基钻井液随钻堵漏技术,并在焦页195-1HF井进行现场应用,取得了良好的应用效果,不仅降低了焦页195-1HF井的钻井成本,同时缩短了钻井周期。
