一种胶筒锚定分层注水管柱及方法
摘要：
本发明公开了一种胶筒锚定分层注水管柱及方法，分层注水管柱包括油管，在所述油管上自上而下设置有上配水器、中配水器、下配水器，在所述油管上还设置有上锚定封隔器、分层封隔器、下锚定封隔器，所述上配水器、中配水器之间以及中配水器、下配水器之间都设置有分层封隔器，所述上锚定封隔器位于上配水器的上方，所述下锚定封隔器位于下配水器的下方。所述上配水器、中配水器之间以及中配水器、下配水器之间都设置有层间锚定封隔器。锚定封隔器的配合应用有效锚定分层注水管柱，保障分层密封效果，延长管柱有效期，同时，避免了对套管的损伤及消除后期检管遇卡交大修的风险。
摘要（英）：

The invention discloses a rubber sleeve anchoring and layering water injection tubular column and method. The layering water injection tubular column comprises an oil pipe, wherein an upper water distributor, a middle water distributor and a lower water distributor are arranged on the oil pipe from top to bottom; an upper anchoring packer, layered packers and a lower anchoring packer are also arranged on the oil pipe; the layered packers are arranged between the upper water distributor and the middle water distributor and between the middle water distributor and the lower water distributor; the upper anchoring packer is located above the upper water distributor; and the lower anchoring packer is located below the lower water distributor. The interlayer anchoring packers are arranged between the upper water distributor and the middle water distributor, and between the middle water distributor and the lower water distributor. By virtue of the cooperative application of the anchoring packers, the layered sealing effect of the anchoring and layering water injection tubular column can be ensured, the validity period of the tubular column can be prolonged, in the meantime, the damage toa casing pipe can be avoided, and the risk of pipe blockage and major repair in later period can be eliminated.
