一种分层注水管柱
摘要：
本实用新型提供一种分层注水管柱，其包含有油管柱、补偿器、球座及多级封隔注水单元，所述补偿器位于所述油管柱的上端，所述球座连接于所述油管柱的底端，而各所述封隔注水单元依次设置于所述补偿器及球座之间，其中，各所述封隔注水单元分别由一水力锚定器、一逐级解封封隔器及一测调连动偏心配水器构成，所述水力锚定器、逐级解封封隔器及测调连动偏心配水器依次与所述油管柱相连接。本实用新型提出的分层注水管柱，能提高注水管柱工作可靠性，增加分注级数，进而提升细分注水技术水平。
摘要（英）：

The utility model provides a separated-layer water injection tubular column, which comprises an oil tubular column, a compensator, a ball seat and multistage packing water injection units. The compensator is located at the upper end of the oil tubular column, the ball seat is connected to the bottom end of the oil tubular column, and the packing water injection units are arranged between the compensator and the ball seat in sequence. Each packing water injection unit is respectively composed of a waterpower anchor, a step-by-step releasing packer and a test modification linkage eccentric water distributor which are connected with the oil tubular column in sequence. The separated-layer water injection tubular column can improve working reliability and increase the number of separated injection stages and further improve levels of subdivided water injection technology.
