该技术目的是进入原完井层段以上、油管以下的储层,以便在原有采油封隔器和地面之间形成新的环空隔板。主要在新产层之上无法下入采油封隔器时应用。该项新技术通过在生产井、注水井、斜井套管内目的油层以上或以下设水泥循环孔,然后用电缆或钢丝以及泵送设备来进行水泥封隔重完井作业。成功进行了几口井的现场试验,证明该项技术完全可行。
The technology aims to reach reservoirs above the original completion section and below the tubing to create a new annulus between the original production packer and the ground. Mainly in the new production layer above the oil packer can not be applied. The new technology works by cement-plugging well completion by providing cement circulation holes above or below the target formation in production wells, water injection wells, off-set casing, and then with cables or wires and pumping equipment. The successful field trials of several wells proved the technology is completely feasible.
