Abstract
The utility model relates to screw pump oil exploitation equipment without an oil pumping rod used in oil exploitation. A rotor (4) is directly driven to rotate by an oil pipe (1) through a high pressure sealing device (2) and a gimbal joint (3), and a stator is connected with a locking device (7) and a friction device (8) by a tail pipe (6), and is locked on a sleeve pipe wall. The screw pump oil exploitation equipment without an oil pumping rod used in oil exploitation is mainly characterized in that the screw pump oil exploitation equipment without an oil pumping rod used in oil exploitation is not provided with an oil pumping rod. The rotor which rotates and the stator which is locked to be stationary form cavity chamber effect to generate an oil pumping function. The crude oil under a well is pressurized, and is raised onto the well by the oil pipe to enter an oil transport pipeline. The screw pump oil exploitation equipment without an oil pumping rod used in oil exploitation has novel design, reasonable structure, convenient work, and low cost. The screw pump oil exploitation equipment without an oil pumping rod used in oil exploitation is oil exploitation equipment for wide oil fields.
Description
The utility model relates to the no sucker rod screw pump mechanical oil recovery equip ment that uses in a kind of oil exploitation.During this oil production equipment is specially adapted to, the viscous crude of deep fat, the exploitation of sandy crude.At present, the single screw pump that use in the oil field is by ground drive system, it is rotatablely moved be delivered to the down-hole rotor by the oil pumping leverage, with is connected with oil pipe system, be suspended on the fixed down-hole of opening stator generation chamber effect, down-hole crude oil is lifted to the aboveground oil pipeline that enters.Every mouthful of oil well uses the sucker rod and the annex thereof of over thousands of rice, expense reaches surplus the 2.5-4 ten thousand yuan, in order to save oil field user's fund, reduce the operating cost of going into the well, structure and driving principle to existing screw-pump oil-extraction equipment are improved, and the cancellation sucker rod is not only saved operating cost, but also strengthened pump setting depth, make screw pump oil production enter the deep-well oil reservoir.
The purpose of this utility model provides a kind of screw pump oil production device that does not have sucker rod.In being applicable to, the oil exploitation of deep layer. promptly can be used for thin oil, also can be used for viscous crude, the exploitation of sandy crude.
The purpose of this utility model is achieved in that rotatablely moving by oil pipe of surface drive, and the core barrel of high pressure sealing, universal joint are delivered to the down-hole rotor, make rotor rotation.Connect tail pipe under the stator, stator is fixed on the casing wall, be maintained fixed motionless by the lock friction, like this, rotor rotated and motionless stator relatively rotate, and form the chamber effect and produce pumping effect, and down-hole crude oil supercharging is lifted to the aboveground petroleum pipeline that enters.
Owing to adopt technique scheme, under situation, obtained the oil recovery effect without sucker rod.And owing to adopt oil pipe to drive rotor, because of its torsional stiffness is big, supporting capacity is strong, and has deepened pump setting depth greatly, but mining depth reaches the crude oil of oil reservoir more than 2000 meters.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the longitudinal sectional view of the utility model embodiment.Figure is: 1 oil pipe, 2 high pressure sealing devices, 3 universal joints, 4 rotors, 5 stators, 6 tail pipes, 7 locks, 8 frictions.
Oil pipe (1) upper end is connected with the reducer output shaft of ground drive system, and the lower end is connected with the rotatable hollow shaft of high pressure sealing device upper end, and its effect is rotating speed and the moment of torsion that transmits ground drive system output. and the Crude Oil Transportation that pumps is extremely aboveground.The hollow mandrel upper end of high pressure sealing device (2) is connected with oil pipe, and its lower end is connected with universal joint.Its shell body links to each other with stator, constitutes the high pressure sealing chamber, prevents that the crude oil leakage that pumps from entering in the sleeve pipe, and crude oil is entered in the oil pipe by the hollow mandrel that has the side direction slotted hole.Universal joint (3) upper end connects the axle of high pressure sealing.The lower end is connected with rotor.Be used to absorb the eccentric motion of rotor and rotatablely move and be delivered to rotor.Rotor (4) and fixed stator (5) relative motion, the generation pumping effect enters high-pressure sealing chamber with down-hole crude oil pump to stator upper end and supercharging is lifted to well head.Tail pipe (6) upper end is connected with stator, and the lower end connects lock, and its side direction is offered slotted hole, is used for the down-hole crude oil in the sleeve pipe is entered into the stator tail end.Lock (7) is used to lock stator, makes its maintenance motionless, and friction (8) is connected with lock, when well operations under the pump and down to giving the whole devices that are used to hold when depthkeeping is spent on it, prevents the landing shaft bottom.
Characteristics of the present utility model are to piece together to abandon conventional screw and adopt the driving sucker rod that there is not pump , lock motionless deciding and directly adopt oil pipe to drive rotor with adopting lock Son forms the chamber effect, reaches the purpose of oil recovery. Its compact conformation, cost saving , operation is convenient, is the desirable oil production equipment in vast oil field.
