The utility model mainly comprises an upper joint 1, an outer casing pipe 2, a hollow transmission shaft 3, a bearing seat 4, an O-shaped sealing ring 11, an anti-rotating pin 12, a spacer sleeve 13, a deep groove ball bearing 14, a lower joint 15, etc. The utility model is mainly used for the oil/water separation of screw pump wells, is convenient in construction operation as well as flexible in rotation, and simultaneously has the advantage of better oil/water separation effect.
Description
Technical field: the utility model relates to oil field development oil production technology technical field, belongs to a kind of oil field screw bolt well oily-water seperating equipment.
Background technology: oily water separation technique under the screw bolt well, be that screw pump and oil water separator are used, make the crude oil mixed liquor in the pit shaft directly realize water-oil separating in the down-hole, isolated low wet crude is given rise to ground, and isolated water is injected into the water filling layer.This technological requirement oil water separator can be done synchronously in company with rod string and rotatablely move, and the energy transfer torque, drives the rotor rotation, realizes that underground oil-water separates.In addition, before screw pump oil production well is gone into operation, need to carry dead space, therefore require downhole separation system in pit shaft, to move up and down.
Existing hydrocyclone, as shown in Figure 2, it is made up of eliminator overflow end cap 5, separator inlet 6, eliminator overflow lip 7, separator main body 8, shell separator 9, eliminator lower contact 10.Wherein eliminator overflow lip 7 is welded on the endoporus of eliminator overflow end cap 5, separator inlet 6 welds together with eliminator overflow end cap 5, separator main body 8 is welded on the endoporus of separator inlet 6, shell separator 9 welds together with separator inlet 6, and eliminator lower contact 10 is welded on the endoporus of shell separator 9.Existing hydrocyclone can not rotate with sucker rod, does not satisfy the requirement of water-oil separating technology under the screw bolt well.
Summary of the invention: the purpose of this utility model be overcome the weak point of prior art and provide a kind of can be before screw bolt well be gone into operation, can move axially and carry dead space, during the screw bolt well running, can rotate synchronously in company with rod string, and the energy transfer torque drives removable, the rotary downhole separation system that rotor rotates.The utility model is made up of top connection, outer tube, Hollow Transmission Shafts, bearing support, eliminator overflow end cap, separator inlet, eliminator overflow lip, separator main body, shell separator, eliminator lower contact, O RunddichtringO, stop pin, spacer, deep groove ball bearing, lower contact.Wherein top connection connects with outer sleeve upper by screw thread, and the outer tube lower end connects with lower contact by screw thread.Be with deep groove ball bearing and spacer on the Hollow Transmission Shafts, Hollow Transmission Shafts and deep groove ball bearing interference fit, deep groove ball bearing is sitting in the bearing support simultaneously.The Hollow Transmission Shafts lower end is with the O RunddichtringO, and Hollow Transmission Shafts connects with eliminator overflow end cap by screw thread.Be with the O RunddichtringO with the Hollow Transmission Shafts upper end of eliminator lower contact lower end by thread connection, also be with deep groove ball bearing and spacer simultaneously, Hollow Transmission Shafts and deep groove ball bearing interference fit, deep groove ball bearing is sitting in the bearing support.Bearing support external diameter sidewall is milled with an elongated slot, is drilled with through hole on the sleeve outer wall outside, and stop pin one end extend into by through hole in the elongated slot of bearing support, and other end weldering is extremely outside on the sleeve outer wall.The utlity model has following advantage: it can move axially carries dead space; During the screw bolt well running, rotate synchronously, drive the screw pump rotor rotation in company with rod string, easy to operate during construction, rotate flexibly, have oil-water separation preferably simultaneously.
Description of drawings: Fig. 1 is the utility model structure diagram;
Fig. 2 is existing hydrocyclone structure diagram.
The specific embodiment: the utility model is made up of top connection 1, outer tube 2, Hollow Transmission Shafts 3, bearing support 4, eliminator overflow end cap 5, separator inlet 6, eliminator overflow lip 7, separator main body 8, shell separator 9, eliminator lower contact 10, O RunddichtringO 11, stop pin 12, spacer 13, deep groove ball bearing 14, lower contact 15.Wherein top connection 1 connects with outer tube 2 upper ends by screw thread, and outer tube 2 lower ends connect with lower contact 15 by screw thread.Be with deep groove ball bearing 13 and spacer 13 on the Hollow Transmission Shafts 3, Hollow Transmission Shafts 3 and deep groove ball bearing 14 interference fit, deep groove ball bearing 14 is sitting in the bearing support 4 simultaneously.Hollow Transmission Shafts 3 lower ends are with O RunddichtringO 11, Hollow Transmission Shafts 3 connects with eliminator overflow end cap 5 by screw thread, be with O RunddichtringO 11 with Hollow Transmission Shafts 3 upper ends of eliminator lower contact 10 lower ends by thread connection, also be with simultaneously deep groove ball bearing 14 and spacer 13, Hollow Transmission Shafts 3 and deep groove ball bearing 14 interference fit, deep groove ball bearing 14 is sitting in the bearing support 4.Like this, hydrocyclone can rotate in company with sucker rod in bearing support 4 synchronously.Simultaneously, bearing support 4 external diameter sidewalls are milled with an elongated slot, are drilled with through hole on outer tube 2 outer walls, and stop pin 12 1 ends extend into by through hole in the elongated slot of bearing support 4, and the other end welds extremely on outer tube 2 outer walls.Hollow Transmission Shafts 3 drive hydrocyclones, deep groove ball bearing 14 and bearing support 4 can move up and down together when carrying dead space, and when cyclone rotated, stop pin 12 can prevent that bearing support 4 from rotating.
The crude oil mixed liquor of screw pump pumping tangentially enters from separator inlet 6, and isolated low wet crude is given rise to ground by eliminator overflow lip 7, and isolated water is injected into the water filling layer downwards along separator main body 8.
When going into the well, the utility model is connected in above the screw pump.Removable, rotary downhole separation system top connection 1 links with oil pipe, and lower contact 15 links with screw pump stator.Removable, rotary downhole separation system upper end connects with sucker rod by Hollow Transmission Shafts, and the lower end connects with screw pump rotor by Hollow Transmission Shafts.Before screw bolt well was gone into operation, downhole separation system can move axially together in company with rod string and carry dead space.During the screw bolt well running, downhole separation system can rotate synchronously in company with rod string, and can drive the screw pump rotor rotation by transfer torque.
The crude oil mixed liquor of screw pump pumping tangentially enters from removable, rotary downhole separation system inlet, and isolated low wet crude is given rise to ground, and isolated water is injected into the water filling layer through Hollow Transmission Shafts.
