Description
Technical field:
The utility model relates to a kind of wellhead assembly that is used for the crude oil with high solidifying point exploitation.
Background technology:
Crude oil with high solidifying point is the higher petroleum resources of a kind of using value, this kind crude oil is because its high content of wax thereby freezing point are higher, in exploitation lifting process, the output liquid temp is constantly descended along the journey heat waste, crude oil condensation viscosity increases severely, flow resistance increases even can't flow, and must can lifting recover the oil by make temperature in wellbore be higher than the above uniform temperature of freezing point along Cheng Jiare after.At present, the oily with fixed attention heating exploitation method of the height of field by using mainly contains hollow stem cable hot line heating pour point depression and two kinds of methods of electric heating oil pipe heating viscosity reduction on the pump.The major defect of these methods is complex process, needs to be equipped with special-purpose electric equipment, and the energy consumption height, investment is big, the wherein preceding average individual well day power consumption of a kind of method 849KW.h, and individual well is invested 18.95 ten thousand yuan; The 2. average individual well day power consumption 740KW.h of method, individual well is invested 11.6 ten thousand yuan; Therefore, make height coagulate oily cost for oil production and heighten that economic benefit is had a strong impact on.
The utility model content:
The purpose of this utility model is to be to provide a kind of two-tube water mixing flange apparatus that height coagulates oily two-tube water mixing oil production technology that is used for.
The utility model is to realize like this.This device is by last, following tubing nipple, the high pressure flange dish, high pressure clip head, high pressure water mixing clip, high pressure elbow, the movable joint cap, packing ring, water mixing pipe pipe nipple, gland, on, the lower support ring, packing, taper location slips is formed, its structure, assembled relation is as follows: on the eccentric orfice of high pressure flange dish, the lower end is connected with following tubing nipple with last tubing nipple by screw thread respectively, last tubing nipple upper end and high pressure clamp connection, be provided with water mixing pipe pipe nipple in another eccentric orfice of high pressure flange dish, the outside, water mixing pipe pipe nipple bottom is provided with taper location slips, it is firmly blocked letter, be followed successively by the lower support ring on the slips of taper location, packing, upper support ring and gland, gland is regulated thrust to guarantee packing_seal by 2 bolts that are screwed into high pressure flange, water mixing pipe pipe nipple upper end is connected with movable joint cap on being enclosed within high pressure elbow, packing ring is housed therebetween, and the high pressure elbow other end is connected with high pressure water mixing clip.During work water mixing pipe pipe nipple lower end is connected with the water mixing tubing string, the high pressure water mixing clip other end is connected with the hot water piping of mixing of standing from oil recovery, hot water is imported oil well water mixing tubing string, to descend the tubing nipple lower end to be connected with flow string in the oil well, high pressure clip head upper end is connected the derivation that realizes down-hole extraction liquid with the little four-way of production tree.
The utility model is reasonable in design, and reliable operation utilizes it can the two-tube water mixing oil production technology of smooth implementation, cuts down the consumption of energy significantly, realizes that height coagulates oily low-cost viscosity reduction exploitation.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is by descending tubing nipple 1, high pressure flange dish 2, last tubing nipple 3, high pressure clip head 4, high pressure water mixing clip 5, high pressure elbow 6, movable joint cap 7, packing ring 8, water mixing pipe pipe nipple 9, gland 10, upper support ring 11, packing 12, lower support ring 13, taper location slips 14 to form.Wherein, high pressure flange dish 2 middle parts have eccentric orfice upper and lower end of two coequal eccentric orfices to be respectively equipped with tubing nipple 3 to be connected with following oil pipe short circuit 1 and to use internal thread, and the latter half of another eccentric orfice is that up big and down small bellmouth the first half is isometrical circular hole.High pressure elbow 6 upper ends are connected the step of using external screw thread, lower end to be provided with suit movable joint cap 7 with high pressure water mixing clip 5.Water mixing pipe pipe nipple 9 lower ends are provided with to be connected with the water mixing tubing string and use screw thread, upper end to be provided with step to use screw thread with being connected with the movable joint cap.
