The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, provides a kind of reasonable in design, easy for installation and can realize the special-purpose diving electric pump of the oil recovery well head that electric pump and plain tubing hanger exchange.
The concrete technical scheme of the utility model is: comprise interconnective oil pipe four-way and upper cover flange, boll-weevil hanger is installed both, the inner surface of described oil pipe four-way upper end is provided with positioning groove, and described boll-weevil hanger lower edge is provided with the guide way that coordinates the location with described positioning groove.During installation, the guide way of boll-weevil hanger lower edge is embedded in the positioning groove of oil pipe four-way, can realizes the guide-localization effect, this design can also realize that the electric pump boll-weevil hanger is with the exchange of plain tubing hanger.
The lower end of described boll-weevil hanger is provided with pallet, and described guide way is arranged on the edge of pallet.Be boll-weevil hanger and pallet split-type design, will both be assembled into one during installation.
Described boll-weevil hanger is the eccentric oil pipe hanger, and its lower end is provided with lower interface channel; Described upper cover flange is provided with interface channel; Connect by connecting rod between described upper and lower interface channel, and the other end of upper and lower interface channel connects respectively outside hydraulic control wire terminal, bottom hydraulic control wire terminal; The hydraulic control line that is this electric pump well head adopts split-type structural, and two ends connect respectively the liquid controling pipe line of outside and bottom by short circuit, do not need threading, easy construction.Described connecting rod and lower interface channel are threaded connection, and described connecting rod and upper interface channel junction are provided with sealing device, connect Simple fast.
The internal diameter at installation boll-weevil hanger place, described oil pipe four-way upper end is 7 〞, with the electric pump well head by 11 " these are designed to 7 " but economical with materials, reduce production costs, dwindle the hanger size, can directly connect cable, easy to operate, and adopt cable sealing ring and cable pressing plate just can realize 7 " diving electric pump well head under the pressure of 35MPa, the temperature rank is at P.U(-29 ℃~121 ℃) sealing function under grade.
Described connecting rod and lower interface channel are threaded connection, and described connecting rod and upper interface channel junction be provided with sealing ring, prevent that hydraulic fluid from revealing; Be provided with sealing ring between described boll-weevil hanger and oil pipe four-way, prevent the leakage of extraction oil.
The utility model can be realized the electric pump boll-weevil hanger with the exchange of plain tubing hanger, and the wellhead fluid control line of split-type design does not need threading in addition, constructs very convenient; Fill up in addition the domestic situation of only having 11 〞 electric pump well heads at present, can reduce production costs, and not need the installing cables penetration device, construct convenient.
