摘　　要：针对大庆油田海拉尔地区部分井试完一层油后,上返压裂第2层时,不下桥塞封闭已试层,直接利用水力泵求产管串中的封隔器暂时封闭已试层,进行上部压裂层排液求产存在砂卡管柱的问题,开发了跨隔压裂层与水力泵返排联作工艺,并研制了和该工艺管柱配套使用的短型水力喷射泵,优选了跨隔用封隔器。经现场应用表明,该施工工艺在缩短施工周期的同时,实现了封层、求产一体化施工,避免了砂卡现象,操作过程安全、可靠。Some wells confine bed of completed interval when fracturing the second interval after testing the first interval in Hailaer. That is, packer of hydraulic jet pump production string con-fine completed layer temporarily, then top fractured interval begin unloading and production.However, the above technology has problem of string sanding in. So we developed the combination technology of straddle fractured interval and hydraulic jet pump flowback, short hydraulic jet pump to match the technology string, and straddle packer. Field application shows that the technology not only shortens operation period but also realizes integrated operation of seal coat and production and avoids sanding in.
