Abstract
The utility model relates to a rod-type thermal recovery oil well pump for recovering thick oil. The utility model is composed of an outer working barrel portion and an oil well pump portion arranged in the outer working barrel portion, wherein, a positioning pawl spring (29) is pressed between a lower contact (26) of an outer barrel and an outer barrel (30) of the pawl spring of the outer working barrel portion; an outside between an oil outlet valve cover joint (5) of the fixed part of the oil well pump and a pump barrel upper coupling (10) is sheathed with a sand blocking ring (9); the outside of a sealing spindle (34) is shaethed with a sealing ring (25), a sealing body (23) and a sealing spacing ring (24) at intervals. The utility model has the advantages of reasonable structure and reliable work; the utility model can be utilized to well recover the thick oil under the condition of thermal recovery, particularly relieve the working capacity of lifting and lowering oil pipes during pump inspection operation and reduce operators' labor intensity and production cost.
Description
The utility model relates to a kind of downhole hardware that is used for the heating exploitation viscous crude: rod-type oil recovery by heating oil well pump.
The existing oil well pump that is used for oil recovery by heating is tubing pump.This kind oil well pump is made up of pump barrel, plunger, hollow draw-bar, standing valve, traveling valve etc., in the oil pump tubular column lower going-into-well, when finishing the oil pumping action, allow cable or viscosity depressant from the hollow stem of pump, to pass through, enter heating in crude oil under the pump, reduce crude oil and advance pump viscosity.Must remove tubing string when the major defect of tubing pump is pump detection and workover, thereby bring adverse effect for thick oil thermal extraction pump detection and workover cost and exploitation effect.
Thereby being to provide a kind of, the purpose of this utility model can when pump detection and workover, needn't remove the rod-type oil recovery by heating oil well pump that oil pipe can significantly reduce the underground work workload, reduce operating worker labor intensity and cost for oil production.
The utility model is to realize like this.This kind rod-type oil recovery by heating oil well pump is by outer working tube and place the oil well pump two-part in it to form, and the outer working tube part is made up of urceolus upper connection, urceolus, tubing coupling, sealed outer cylinder, urceolus lower contact, pawl spring urceolus, location pawl spring and tubing nipple.The oil well pump part is made of standing part, active part, wherein, standing part comprises box cupling on oil-release valve cover, valve bonnet joint, delivery valve seat, sand stop ring, the pump barrel, pump barrel, pump barrel lower contact, sealing mandrel, seal ring, seal, sealing spacer ring, alignment axis; Active part comprises hollow stem upper connection, locking nut, upward hollow draw-bar, outlet valve, plunger pressure ring, plunger pull bar, plunger upper connection, plunger, oil-feed valve seat, oiling valve, hollow stem are set upright joint, hollow stem pipe nipple and hollow stem lower contact.During pump, the outer working tube part is lowered to the oil well pump part in the tubing string with hollow-rod string then earlier with in the tubing string lower going-into-well under the first time.When oil well pump enters outer working tube, alignment axis and urceolus lower contact are that the conical surface seals firmly, the alignment axis lower convex platform enters pawl spring lower end, location, the oil well pump pump barrel is not blocked and can move by pawl spring when guaranteeing normal the oil pumping, simultaneously seal, sealing spacer ring, seal ring enter sealed outer cylinder and with its sealing, make to be pumped into that the liquid in the tubing string is unlikely on the pump drains under the pump, sand stop ring then enters urceolus upper connection middle part and blocks sand in the tubing string.During afterwards pump detection and workover, needn't remove tubing string, only need rod string oil well pump can be tripped out, more renew to be lowered in the tubing string with rod string again behind the pump and get final product.
The utility model is rational in infrastructure, and reliable operation is utilized its not only heavy crude producing under the condition of oil recovery by heating preferably, particularly can remove removing in applying when pump detection and workover from.
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is a black box position partial structurtes enlarged diagram.
Below in conjunction with accompanying drawing enforcement of the present utility model is further specified.
As shown in the figure, the utility model is made up of outer working tube and oil well pump two-part.The outer working tube part is followed successively by urceolus upper connection 8, urceolus 11, tubing coupling 21, sealed outer cylinder 22, urceolus lower contact 26, pawl spring urceolus 30, tubing nipple 32 from top to bottom, has compressed location pawl spring 29 between urceolus lower contact 26 and the pawl spring urceolus 30.The oil well pump part is made up of standing part and active part, standing part is followed successively by box cupling 10 on oil-release valve cover 4, oil-release valve cover joint 5, the pump barrel, pump barrel 19, pump barrel lower contact 21, sealing mandrel 34, alignment axis 27 from top to bottom, on oil-release valve cover joint 5 and the pump barrel between the box cupling 10 inside compress delivery valve seat 7, outer cover is equipped with sand stop ring 9, and sealing mandrel 34 outside spacer sleeves are equipped with 25,2 seals 23 of 2 seal rings and 1 sealing spacer ring 24 (see figure 2); Active part is followed successively by hollow stem upper connection 1, locking nut 2 from top to bottom, upward hollow draw-bar 3, plunger pressure ring 12, plunger pull bar 15, oiling valve 17, hollow stem are set upright joint 18, hollow stem pipe nipple 28, hollow stem lower contact 31, last hollow draw-bar 3 outer cover are equipped with outlet valve 6, be Spielpassung between two, be set with the plunger upper connection 13, plunger 14, the oil-feed valve seat 16 that fuse between plunger pull bar 15, plunger pressure ring 12 and the oiling valve 17 from top to bottom.More than all links be and be threaded.In the above-mentioned parts, except that seal 23, seal ring 25 materials are that thermostable fluorine rubber, location pawl spring 29 materials are that all the other are Steel Work the spring steel.Wherein, pawl spring 29 tops, location are positioning ring, and the bottom is along circumferential 3-6 uniform elasticity pawl spring.
