Abstract
The utility model belongs to a stator of a screw pump used for oil production in an oil field, which is composed of a screw pump barrel 1, a rubber bushing 2, a cavity 3 and the like. The rubber bushing 2 is of an equal-wall thick rubber with same distribution. The utility model is developed to extend working life of the screw pump, the purpose of energy saving and consumption reduction can also be achieved, and further the economic profit of oil production with the screw pump can be raised. The utility model is mainly used for oil production of the screw pump in the oil field, and has the advantages of high bearing, low torque, short pump body, lower needed power supply, large output volume and the like.
Description
Belong to oil field oil recovery screw pump stator Deng wall thickness rubber screw pump stator.
Recover the oil and use screw pump stator in existing oil field, as shown in Figure 3, cast in steel body pump barrel 1 ' interior formation by nitrile butadiene rubber, lining 2 ' internal surface be the double helix curved surface, when its became uneven, this screw pump stator rotary work, in the thickest part of spiral, heat is assembled easily, causes the stator premature failure easily, has shortened the working life of screw bolt well.
The purpose of this utility model is to improve the deficiency of conventional screw pump stator technology, prolongs the operating life of screw pump, reaches energy-saving and cost-reducing, improves the screw pump oil production economic benefit and a kind of wall thickness rubber screw pump stator that waits of developing.
The utility model is made up of spiral pump barrel, rubber bushing, cavity etc.
Wherein rubber bushing evenly sulfuration on the inwall of spiral pump barrel, rubber bushing be thickness equate wait wall thickness rubber, and its inner and outer surface distorted shape in the shape of a spiral, the inside of rubber bushing is cavity.
The outer surface of spiral pump barrel can be straight, and the internal surface of spiral pump barrel can be and vulcanize the same distorted shape in the shape of a spiral of rubber bushing of wall within it.
The inner and outer surface of spiral pump barrel can also be the same helically twisted shape of wall thickness such as be with the rubber bushing inner and outer surface that vulcanizes wall within it.
The utility model compared with prior art has following advantage:
1, good heat dissipation characteristics makes stator in the running, has better mechanical property, and the damage that stress or wearing and tearing cause is also less.
2, rubber changes uniformly, because rubber thickness is even, rubber is subjected to external force and medium to do the time spent, and performance variation is also consistent, is more convenient for joining pump.
3, pressure-bearing height, moment of torsion is low, and the pump housing is short, and power demand is lower, discharge capacity is bigger, can use in worse environment.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is an another kind of structure diagram of the present utility model;
Fig. 3 is existing conventional screw pump stator structure diagram;
Fig. 4 is a The field sketch of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
The utility model is made up of spiral pump barrel 1, rubber bushing 2, cavity 3 etc.
Wherein rubber bushing 2 evenly sulfuration on the inwall of spiral pump barrel 1, the rubber such as wall thickness such as grade that rubber bushing 2 equates for thickness, and its inner and outer surface distorted shape in the shape of a spiral, the inside of rubber bushing 2 is cavity 3.
The outer surface of spiral pump barrel 1 can be straight, and the internal surface of spiral pump barrel 1 can be and vulcanize the rubber bushing 2 the same distorted shapes in the shape of a spiral of wall within it.
The inner and outer surface of spiral pump barrel 1 can also be the same helically twisted shape of wall thickness such as be with rubber bushing 2 inner and outer surface that vulcanize wall within it.
During site operation, at first by working design assembly tubing string, then according to the order of plug tail pipe 10, screen casing 9, wax control device 8, anchor tool 7, the utility model 6, tubing centrilizer 5, oil pipe 4 successively down to the design pump setting depth, by working design assembly roofbolt, drive unit and automatically controlled part are installed, open the machine running.The pump pressure that this new screw pump produces allows on the length to shorten greater than several times more than of conventional pumps, can finish the lifting work of same discharge capacity, and its transmission power obviously reduces.
