摘　　要：针对江陵凹陷新沟嘴组深井地层温度高、应力高、施工压力高等导致的压裂改造困难等问题,选用先进射孔烊复射孔,优化压裂管柱组合降低摩阻,优化液体配方适应储层及精选支撑剂组合匹配裂缝系统,前置酸降低破裂压力,多级粉陶段塞打磨降低近井裂缝弯曲摩阻,提高压裂设备等级等措施,加大了深井的改造强度,提高了泄油面积,取得了一定压裂效果。Given the difficulties in fracturing stimulation caused by high formation temperature,high stress and high operation pressure in a deep well of the Xingouzui Formation in Jiangling sag,such strategies were employed as the selection of sophisticated perforating charges for reperforation,the optimized fracturing string assembly for reducing friction,the optimized fluid recipe for the reservoir and the selection of the proppant combo for the fracture network,the prepad acid for reducing fracturing pressure,the multi-stage powdered ceramic slug milling for reducing near-well fracture bending friction,improving the grade of fracturing equipment,etc.,so as to intensify the stimulation of the deep well and increase the oil drainage area,achieving a certain fracturing effect.
