One, technical field
The present invention relates to a kind of oil production equipment that belongs to the petroleum industry field, specifically a kind of ultra long stroke beam-pumping unit that is applicable to deep mining.
Two, background technology
Oil pumper is the capital equipment in the oil exploitation, and the existing oil pumper of using all has huge fuselage, and the elder of stroke is also all less than 10 meters.High-strength flexible coiled rod and flexible traction piece technical development are very fast in recent years.As the carbon fiber flexible coiled rod, the tensile strength height, the pump degree of depth is increased greatly, but owing to be subjected to the restriction of existing oil pumper length of stroke, still need to adopt the short stroke of the invalid stroke of easy generation, high jig frequency oil pumping mode, can not give full play to the technical advantage of flexible continuous pumping rod, limit the development of deep mining technology.
Three, summary of the invention
The purpose of this invention is to provide a kind of ultra long stroke beam-pumping unit, solve the problem that deep mining increases the oil recovery stroke, reach the purpose of simplifying pumping unit, saving steel, reduce cost and improve crude oil production.
Technical scheme of the present invention realizes in the following manner:
A kind of ultra long stroke beam-pumping unit comprises bearing, counterweight traction piece, flexible rod traction piece, deceleration electric cylinder, shaft coupling, motor, Based Intelligent Control cabinet, base, basis, brake system, the wheel that rises, rises and take turns bridge, counterweight pit shaft, counterweight.It is characterized in that the motorized pulleys two ends are by bearing support, be installed on the base and link to each other with motor on being installed in base by shaft coupling, flexible continuous pumping rod traction piece one end fixedly is wrapped in the centre of electric drum barrel, the other end links to each other with oil well pump by the coiled rod in the pumpingh well again, the counterweight traction piece is made up of two wire rope non-metal ropes, an end fixedly is wrapped in the two ends of the cylindrical shell of deceleration electric cylinder separately, the other end links to each other with counterweight in placing underground counterweight pit shaft separately, the wheel that rises is installed on the preceding wing base by the wheel bridge supporting of rising, can be by the adjusting wheel bridge that rises, make flexible rod centering well head, brake system, the Based Intelligent Control cabinet is installed on the base, and base is installed on the basis.
The basis is a concrete block, and seat is in a side of oil well; The counterweight pit shaft is positioned at the rear side of bearing, and parallel with oil well, but counterweight pit shaft non-metallic pipe or metal tube hang down and insert in the open hole well; Traction piece is also by high-strength flexible nonmetals rope or composite material rope; Motorized pulleys can adopt fixed axis gear transmission motorized pulleys or involute planet gear transmission motorized pulleys or cycloidal-pin wheel transmission motorized pulleys or the non-fitted outside motorized pulleys of motor; Brake system can adopt mechanical brake or aerodynamic brake or electromagnetic brake; The governing system that motor and Based Intelligent Control cabinet constitute can be switched reluctance machines governing system or dc motor speed drive system or ac motor speed control by variable frequency system.
Compared with the prior art the present invention has the following advantages:
1, provides a kind of stroke can sufficiently long extracting device of oil, satisfy an urgent demand of high-strength flexible coiled rod and deep-well oil-extraction technical development.
2, long stroke has reduced the reciprocation cycle number of times of the required oil well pump of unit crude output, thereby has reduced invalid stroke, has improved overall efficiency, tired and the wearing and tearing of rod string have been reduced, prolong the application life of rod string, improved being excused from a college course the phase of oil well, reduced the operation number of times.
3, no frame structure is saved steel, and machine volume is little, and is rational in infrastructure, and is simple compact.
4, adopt the motorized pulleys of the electromechanical integration of speed governing commutation Based Intelligent Control, can realize speed governing rotating commutation, but stroke jig frequency step-less adjustment, and the uplink and downlink speed of polished rod can be distinguished independent control, transfers ginseng convenient and swift, can adapt to various hole conditions.
5, accurate counterweight balance mode, balanced ratio can reach more than 95%.
6, articulating with breaking away from of sucker rod and counterweight do not need work high above the ground, can finish on ground, and it is reliable to install and use maintenance safe.
Four, description of drawings
