摘要
进行地层三个压力预测对钻井施工十分重要 ,它是确定合理钻井液密度图版和井身结构的基础。利用自适应井壁稳定技术、邻井测井资料和钻井资料 ,系统分析了海南福山凹陷地层的三个压力剖面 ,并在花 X4井中进行了应用。现场施工结果表明 ,该方法有效地解决了流二段泥页岩地层的坍塌问题 ,该井与邻井相比钻井周期缩短 65 d。
Estimates of three pressures is very important for drilling operations. It is the base of deciding reasonable mud density diagram and well configuration. Three pressure profiles are systematically analyzed in Fushan depression formation in Hainan, using self adapting well stabilizing technique, adjacent well logging data and drilling data are applied in well Hua X4. The field operation shows that this method can effectively solve shale sloughing in Liuer formation. The drilling cycle is decreased by 65 day...
