Abstract
An energy-saving hydraulic oil pumping unit comprises a hydraulic pump, an overflow valve, a one-way valve, an energy accumulator, an electro-hydraulic directional valve, an assembled oil cylinder and other parts, wherein the assembled oil cylinder comprises a piston cylinder and a plunger type cylinder, a plunger piston of the plunger type cylinder is used as a cylinder barrel of the piston cylinder, and a piston rod of the piston cylinder is fixed on a bottom cover of the plunger type cylinder to cause the assembled oil cylinder to form three oil chambers. The energy-saving hydraulic oil pumping unit can recover the gravitational potential energy released during descending of a sucker rod, and reutilize the energy generated during rising of the sucker rod, thereby achieving the energy-saving effect. The assembled oil cylinder can realize both operating function and balance function; therefore, the utility model has the advantages of compact structure, small occupied area and the like.
Description
(1) technical field
The utility model relates to oil exploration equipment, is a kind of energy-conserving hydraulic pumping unit specifically.
(2) background technology
Along with continually developing of China oil field, the most of oil field of east China has entered the middle and later periods of waterflooding extraction, in order to improve the production efficiency of viscous crude well yield and oil reservoir, requires oil production equipment must have the characteristics of long stroke, low jig frequency.At present, beam pumping unit remains the main force of pumping unit, but there are shortcomings such as stroke can not increase substantially in it.Characteristics such as hydraulic pumping unit is because have compact integral structure, and is in light weight, and length of stroke and number of strokes are easy to adjust will be developed in the oil producing operation in oil field faster.But general hydraulic pumping unit also will dispose balancing cylinder, so structure is not compact except that the main operating cylinder of configuration, floor space is big.
(3) summary of the invention
Problem to be solved in the utility model is the shortcoming and defect that overcomes and avoid existing in the above-mentioned prior art, and a kind of long stroke, compact conformation, energy-conserving hydraulic pumping unit that floor space is little are provided.
The technical scheme that its technical problem that solves the utility model adopts is: energy-conserving hydraulic pumping unit, comprise hydraulic pump 1, overflow valve 2 and 3, one way valve 4, accumulator 5 and electro-hydraulic reversing valve 6, its special character is also to comprise combined oil cylinder 7, combined oil cylinder 7 is combined by a piston rod and a plunger case, the cylinder barrel of the plunger 74 double as piston rods of plunger case, the piston rod of piston rod is fixed on the bottom of plunger case.Combined oil cylinder 7 has three oil pockets 71,72 and 73, and the hydraulic fluid port of oil pocket 71 links to each other with accumulator 5, and the hydraulic fluid port of oil pocket 72,73 links to each other with two hydraulic fluid ports of electro-hydraulic reversing valve 6 respectively.Pulley yoke 8 is equipped with on plunger 74 tops of combined oil cylinder 7, and pulley 9 and 10 is installed on the pulley yoke 8, and wire rope 11 1 ends link to each other with sucker rod 12, and the other end fixes on the ground after walking around pulley 9 and 10.Oil pocket 71 plays the function of general hydraulic pumping unit balancing cylinder, and oil pocket 72 and 73 plays the function of general hydraulic pumping unit operating cylinder.
The utility model compared with prior art has can realize advantages such as long stroke oil pumping, compact conformation, floor space be little.
(4) description of drawings
Fig. 1 is a fundamental diagram of the present utility model;
Fig. 2 is a surface structure schematic diagram of the present utility model.
(5) specific embodiment
As shown in Figure 1 and Figure 2, combined oil cylinder 7 is combined by a piston rod and a plunger case, the cylinder barrel of the plunger 74 double as piston rods of plunger case, and the piston rod of piston rod is fixed on the bottom of plunger case.Like this, combined oil cylinder 7 is divided into three oil pockets 71,72 and 73, and the hydraulic fluid port of oil pocket 71 links to each other with accumulator 5, and the hydraulic fluid port of oil pocket 72,73 links to each other with two hydraulic fluid ports of electro-hydraulic reversing valve 6 respectively.By the commutation of electro-hydraulic reversing valve 6, oil pocket 72,73 is alternately logical with the high-low pressure oil phase.The commutation of electro-hydraulic reversing valve 6 be by control sucker rod about in the of 12 two travel switches of stroke handle.Overflow valve 2 plays the safeguard protection effect, this opening of valves overflow when oil pumper transships.Hydraulic pump 1 can be by one way valve 4 to the 5 oil circuit repairings of oil pocket 71-accumulator.The maximum pressure of overflow valve 3 control oil pocket 71-accumulators 5 oil circuits.Pulley yoke 8 is equipped with on plunger 74 tops of combined oil cylinder 7, and pulley 9 and 10 is installed on the pulley yoke 8, and wire rope 11 1 ends link to each other with sucker rod 12, and the other end fixes on the ground after walking around pulley 9 and 10.Just can drive sucker rod 12 like this and realize up stroke when plunger 74 moves upward, sucker rod 12 is realized down stroke when plunger 74 moves downward.The oil well pump oil pumping that pumps and further drive the down-hole of sucker rod 12.
When moving first, electro-hydraulic reversing valve 6 switches to position, a left side, hydraulic pump 1 is to oil pocket 73 fuel feeding, oil pocket 72 oil returns, this moment is not owing to charge into hydraulic oil in the accumulator 5, oil pocket 71-accumulator 5 loops are in low-pressure state, and hydraulic pump 1 makes plunger 74 up drive sucker rods 12 realize up stroke also to oil pocket 71 fuel feeding.When sucker rod 12 went upward to terminal point, travel switch sent the signal of telecommunication, made the outage of electro-hydraulic reversing valve 6 left end electromagnet, the energising of right-hand member electromagnet, and electro-hydraulic reversing valve 6 switches to right position.Hydraulic pump is to oil pocket 72 fuel feeding, oil pocket 73 oil returns move downward at the effect lower plunger 74 of sucker rod 12 gravity and oil liquid pressure, and sucker rod 12 is realized down strokes, fluid in the oil pocket 71 is squeezed in the accumulator 5 simultaneously, and the gas in the accumulator 5 is compressed and has stored energy.When sucker rod 12 came downwards to terminal point, travel switch sent the signal of telecommunication, made the outage of electro-hydraulic reversing valve 6 right-hand member electromagnet, the energising of left end electromagnet, and electro-hydraulic reversing valve 6 switches to position, a left side.Hydraulic pump is to oil pocket 73 fuel feeding, oil pocket 72 oil returns, and accumulator 5 discharges the energy that reclaimed last time to oil pocket 71 simultaneously, and the oil pressure active force in oil pocket 73 makes plunger 74 up drive sucker rods 12 realize up strokes.Like this, by the continuous reciprocating motion of sucker rod stroke about in the of 12, thereby the oil well pump that can drive the down-hole is realized the operation of pumping crude oil.When two ends, electro-hydraulic reversing valve 6 left and right sides electromagnet all cut off the power supply, sucker rod 12 stopped at an arbitrary position.
The position that changes static position switch is with regard to adjustable stroke length, and regulated variable hydraulic pressure pump delivery just can be regulated jig frequency.
The utility model has utilized the combined oil cylinder of special construction and accumulator to combine, and can reclaim the gravitional force that sucker rod discharges when descending, utilizes again when sucker rod is up, has obvious energy-saving effect.
