Description
Affiliated technical field
The utility model relates to a kind of oil rig that is used for oil field development, especially is fit to the hydraulic pressure walking beam clump formula multiple well interactive self-balancing pumping unit of cluster well crude oil lifting.
Background technology
At present, oil well crude oil lifting equipment all adopts the configuration mode of a motor of a bite oil well, and not only the equipment installation is big, and power consumption is big, and land occupation is many, has improved cost for oil production, has reduced economic benefit.
Summary of the invention
Big in order to overcome existing crude oil lifting equipment installation, the deficiency that power consumption is big, the utility model provides a kind of hydraulic pressure multiple well interactive self-balancing pumping unit that is used for the platform cluster well, more this device utilizes a driven by motor to overlap oil production equipment adjacent many mouthfuls of wells is recovered the oil simultaneously, not only make full use of equipment, improved system mechanics efficient, energy-saving and cost-reducing, and also land occupation is few.
The technical scheme that its technical problem that solves the utility model adopts is: this oil pumper is by horse head, preposition cylinder, and support, walking beam, balance weight, rearmounted cylinder, Stroke Control guiding valve, time-delay overflow shutoff valve, overflow valve, fuel tank, oil pump, variable speed energy saving motor, hydraulic control system, sucker rod, connector, overload protection arrangement and rope are formed.Wherein, horse head, preposition cylinder; support, walking beam, balance weight, rearmounted cylinder, Stroke Control guiding valve, time-delay overflow shutoff valve, connector, overload protection arrangement and sucker rod are formed a cover oil production equipment, and every cover oil production equipment is connected with oil pump with the hydraulic drive parallel way.When the hydraulic control system power switch is connected, variable speed energy saving motor-driven oil pump drives hydraulic work system, under the effect of the power of surging, the plunger of preposition cylinder and rearmounted cylinder pumps respectively, thereby driving walking beam rotates around the walking beam fulcrum, the sucker rod that drives many mouthfuls of wells is simultaneously done and is pumped, and reaches in-place oil is drawn into ground purpose.The variable speed energy saving motor is finished once positive and negative rotation, then drives horse head and once pumps.The stroke of horse head is controlled by the Position Control processor in the hydraulic control system, jig frequency is adjusted the variable speed energy saving rotating speed of motor by hydraulic control system and is adjusted, when the variable speed energy saving rotating speed of motor increases, the jig frequency of horse head also increases, when the variable speed energy saving rotating speed of motor reduced, the jig frequency of horse head also reduced.The Position Control processor that is provided with in the hydraulic pressure level controlling system can be controlled and respectively overlap oil production equipment, and the polished rod load that makes the down stroke oil well is the balance weight of up stroke oil well; When it can not complete equipilibrium, can utilize balancing in situ recanalization balance.Above the connector between sucker rod and the rope, be provided with overload protection arrangement; when polished rod load being increased suddenly because of reasons such as holddowns, surpass the safe load that overload protection arrangement is set, overload protection arrangement just starts; discharge polished rod load, guarantee the safety of equipment such as frame and sucker rod.Time-delay overflow shutoff valve, overflow valve are with effective control oil pressure, and the assurance hydraulic system is normally moved.If every mouthful of oil well condition differs bigger, can the employing ratio join the pump method, promptly according to different well ' s conditions, guaranteeing the pump footpath of arranging in pairs or groups in proportion under identical jig frequency and the stroke situation, to satisfy the requirement of oil pumper to different output oil well synchronous working.
This oil pumper has adopted variable speed energy saving motor, hydraulic drive, realized the design of the shortest transmission combination and the many wells of a machine, the different potential variation that produce with the suspension point change in location of each well polished rod load have been made full use of, greatly improved system mechanics efficient, reduced capital investment, energy consumption and management and maintenance expense, can increase economic efficiency significantly, and it is easily manufactured, safe and reliable, being easy to adjust running parameter, operating simple and easyly, is a kind of high-efficiency and energy-saving type oil production equipment.
