摘要
塔里木盆地储层埋藏深,地层压力系数高,地层破裂压力梯度高。由于施工井口压力高,常规加砂压裂工艺无法实施作业。塔里木油田野云2井通过采用加重压裂液体系和2000型压裂车组更换泵头及高压管线的方法,成功实施了加砂压裂作业,为国内类似井储层改造提供了经验。
Tarim oilfield has features of deeply buried reservoir, high formation pressure coefficient and high pressure gradient of stratum broken. For high well head pressure, the operation of conventional adding sand fracture treatment tech can not fulfilled. By utilizing the method of heavy weight fractured fluid system,2000 model fracturing track unit and high pressure pipe lines to Yeyun2 well in Tarim oilfield, adding sand fracture work has been conducted successfully which provides an experience for reservoir treatment to domestically similar wells.
