Cable type electric measuring and sealing integrated intelligent separate injection instrument

Abstract

The invention relates to the technical field of oil field intelligent water injection, in particular to a cable type electric measuring and sealing integrated intelligent separate injection instrument. The cable type electric measuring and sealing integrated intelligent separate injection instrument comprises an upper end portion, the upper end portion comprises an upper connector, the upper connector is of a cylindrical structure with a cavity inside, and the upper end portion further comprises a first cable head; the packing part is connected with the upper end part, the packing part comprises a rubber sleeve, one end of the rubber sleeve abuts against the end, away from the cable head, of the upper connector, and the packing part further comprises a thrust cylinder and a power mechanism; the separate injection part comprises a pile casing, and the packing part further comprises a nut; the lower end part is connected with the dispensing part, and the lower end part comprises a lower joint; and the central pipe sequentially penetrates through the packing part and the separate injection part, and the other end of the central pipe is inserted into the lower connector. The cable type electric measuring and sealing integrated intelligent separate injection instrument meets the requirement of a small-clamping-distance multi-layer fine separate injection process, meanwhile, the electric setting mode is adopted, sealing of a pipe column does not need to be considered, and the possibility of setting failure is avoided.

Description

technical field [0001] The invention relates to the technical field of oil field intelligent water injection, in particular to a cable-type electric measuring and sealing integrated intelligent dispensing instrument. Background technique [0002] The fine layered water injection technology has played a great role in increasing the production of oil fields, so the fine layered water injection technology has been promoted and popularized. In the related technology, the traditional layered water injection method of mechanical packer and water distributor needs to connect short joints of tubing between the two, which makes the traditional water injection process tool section longer and cannot meet the level of small jigs. Water injection needs. In addition, since the setting and unsealing of the packer are both one-time actions, after the failure of setting, it is necessary to start the new construction, which wastes manpower and material resources. Contents of the invention ...
