Description
Technical field
The utility model relates to machine field, specifically refers to a kind of linear electric motors.
Background technology
At present, sucker rod pumping is that domestic and international petroleum industry applies largest mechanical oil production model.Sucker rod pump structure is simple, easy and simple to handle, easy to maintenance, and discharge capacity is moderate, is applicable to the capacity requirements of most oil well.
But along with the development of In Oil Field Exploration And Development, sucker rod pump exposes series of problems gradually: well rod and tube partial-wear is serious, reduces security of system, improves maintenance cost, had a strong impact on economic benefit; There is too much intermediate link in the beam type four-bar linkage structure generally adopted, causes system effectiveness low, be no more than 0.35; Long stroke pumping unit is bulky and heavy, uses material many, high cost etc.
At present, the approach solved the problem both at home and abroad mainly contains: improve and improve sucker rod pumping system.Bottom such as sucker rod, heavy bar increases the weight of or adopts glass fiber reinforced plastic oil pumping rod and carbon-fiber continuous rod etc., but these class methods are still kept away shortcomings such as unavoidable efficiency is low, failure rate is high, deficiency in economic performance.The linear motor oil pumping machine of rising in recent years is directly connected with sucker rod by flexible connecting member, directive wheel, reduces the power loss in power transmission process, improves system effectiveness, and energy-saving effect is remarkable, but does not break away from well bar eccentric wear problem yet.Another approach adopts the Rodless oil extraction mode such as electric submersible pump, hydraulic piston pump and hydraulic jet pump, although thoroughly break away from this weak link of sucker rod, or adaptability is limited, regulating parameter difficulty, otherwise invest high, the life-span is short, efficiency is low.
Generally the pumping unit utilizing rod string to pump to carry out driving is referred to as sucker rod pumping equipment (the many scales of well number are large); Every without rod string transferring energy, but utilize the pumping unit of cable or highly pressurised liquid transferring energy to be referred to as rodless pumping unit.Although the subsurface progressive cavity device utilizing sucker rod string rotating to move also has sucker rod, listed in rodless pumping unit traditionally.
Common equipment has submersible electric pump, screw pump, hydraulic jet pump and hydraulic piston pump oil rig.Submersible electric pump oil extraction system, submersible electric pump oil extraction system is primarily of parts compositions such as motor, protector, gas-liquid separator, centrifugal multistage pump multiple centrifugal pump, cable, terminal box, control flow and transformers.Except the above-mentioned basic element of character, also can select some appurtenances, as ball-and-seat, gate gurgle valve, centralizer, down-hole pressure measuring instrument and speed-changing driving device etc.The operation principle of this system be ground power supply by transformer, control flow and cable by power delivery to downhole electrical motor, drive centrifugal multistage pump multiple centrifugal pump vane rotary, convert electrical energy into mechanical energy, well liquid is given rise to ground.Electric Submersible Pump System parts have: motor, protector, gas-liquid separator, cable, control flow, transformer, terminal box, pressure sensor, ball-and-seat and gate gurgle valve, centralizer.A kind of novel mechanical extracting device of oil that screw pump is is pumping basis with the swing offset of liquid generation.Screw pump oil production system, screw pump oil production system can be divided into ground by type of drive and drive and the large class of down-hole drive two, and ground driving can be divided into belt transmission and direct-drive two kinds of forms by different driving form, down-hole drive also can be divided into electric drive and hydraulic-driven two kinds of forms.In whole screw pump oil production system, ground drive development comparatively early, also more ripe, but down-hole drive avoids the loss of ground driving torque, equipment is also fewer, has higher oil recovery efficiency.
Current oil pumping mode exists, expend power larger, ineffective systems, there is eccentric wear phenomenon in well rod tube, equipment loss is easily caused to scrap, each stroke acting is different, the power needing motor to provide is different, and the strength needed in the force feed stage is large, and in the oil suction stage hardly with acting, need power very little, if now current of electric size is identical, causes pump housing equipment and be hit larger in the stage needing power little, and two stage required times are different in size, when adopting the drive current of same frequency to control, require higher to control system.
Stroke, jig frequency are all non-adjustable, and discharge capacity adjustable range is narrow, not easily carry out tune ginseng according to oil well productivity.
Jig frequency is non-adjustable, can not adopt the working system of short stroke, high jig frequency, and conventional electric submersible pump captain degree is longer, and the radius of curvature of inapplicable high angle hole is less than electric submersible pump
