Description
Technical field
It is the twin-well oil-pumping machine of power with the permanent magnetic linear synchronous motor that the utility model relates to a kind of, makes full use of the close characteristics of Liang Koujing, realizes that a machine two wells recover the oil simultaneously, the two wells mutual balance of loading.
Background technology
Maturation day by day along with petroleum exploration in China and drilling technology, the cluster well exploitation becomes the oil field development trend day by day, but cluster well has bar oil recovery machiner technology very backward, and improve oil pumping system efficient, reducing the oil pumping system energy consumption is again the effective way that reduces cost of crude oil production and improve the business economic benefit.Therefore, researching and developing the energy-efficient oil pumper that matches with the cluster wells production technology becomes inevitable.
At present domesticly aspect cluster well oil extractor, have breakthrough, multiple twin-well oil-pumping machines such as JPCYJC type cluster well intelligent long stroke oil pumping machine, beam type double-well pumping unit, the two pumping unit of well of broadband type ultra-long-stroke double pump, hydraulic cylinder type double-well oil pumping unit have been researched and developed in succession, all solved individual well unit problem to a certain extent, for recovering the oil with power, the oil twin-well made contribution, but exist shortcoming or weak point: though realized purpose of energy saving, effect is not fairly obvious yet.Tracing it to its cause is because the twin-well oil-pumping machine of present research all also can't be broken away from the restriction of mechanical mechanisms such as deceleration, commutation, and majority is based on the technological transformation of original oil pumper, and structure is complicated more, also becomes the factor of its popularization of restriction.The problem that exists at existing twin-well machine and should influence energy-conservation factor, at present domestic research dispute is also very big.
Summary of the invention
The purpose of this utility model is: change electric energy into rotating mechanical energy in order to overcome traditional twin-well oil-pumping machine, through slowing down and changement changes the sucker rod acting that pumps into, mechanical efficiency is lower, the point suspension movement rule is single, dynamic load is big, energy consumption is big and the shortcoming of stability of a system difference again; Overcome the shortcoming of existing twin-well oil-pumping machine workover treatment telephone-moving difficulty; Avoid existing twin-well oil-pumping machine one well stop pumping, the design defect that another well also can't be worked.The utility model provides a kind of bilateral linear motor twin-well oil-pumping machine.This bilateral linear motor twin-well oil-pumping machine has removed the deceleration changement, can directly utilize linear electric motors to pump and drive the sucker rod operation, not only the movement velocity pattern of suspension point is adjustable, and conveniently abdicate the well workover space, and solved under the well stop pumping situation, another well still can be adopted the problem of taking out operation.
The scheme that its technical problem that solves the utility model adopts is: the bilateral linear motor twin-well oil-pumping machine is by truss (1), linear motor stator electric (2), linear motor rotor (3), tandem-driving bogie (4), bottom commutation guide wheel group (5), polished rod eye A (6), flat rope A (7), the removable guide wheel group in top (8), flat rope B (9), top stator ring group (10), polished rod eye B (11) constitutes, with the double-flanged end permanent magnetic linear synchronous motor is power, utilize guide wheel group (5 respectively, 8) and guide wheel group (10) commutation, polished rod eye A (6) is directly linked to each other with the tandem-driving bogie bottom by flat rope A (7), and polished rod eye B (11) directly links to each other with tandem-driving bogie (4) top by flat rope B (9); The removable guide wheel group in top (8) can move forward and backward simultaneously, to adapt to different well spacing requirements.When linear motor rotor is up, polished rod eye A (6) locates to connect polished rod A and carries out upstroke, simultaneously polished rod eye B (11) locates to connect polished rod B and carries out down stroke, and polished rod eye A (6) locates thrust that polished rod load makes progress by bilateral linear motor (2,3) and polished rod eye B (11) and locates polished rod load and bear jointly; When electric mover was descending, polished rod A and polished rod B carried out down stroke and upstroke respectively, and polished rod eye B (11) locates polished rod load and locates polished rod load by downward thrust of bilateral linear motor (2,3) and polished rod eye A (6) and bear jointly; In the oil pumper running, realized that polished rod A is opposite with the polished rod B direction of motion, can make polished rod load reach the effect of mutual balance.
Effect of the present utility model is:
1. when two mouthfuls of similar wells of hole condition recover the oil, carry out the load at the suspension point place of upstroke and bear by linear motor pushing force and the suspension point place load of carrying out down stroke; Hole condition not simultaneously, the counterweight that adjustable and balancing case (4) is located is to realize the balance of oil pumper.
2. when well A needs well workover, by increasing tandem-driving bogie weight, but also operate as normal of well B.
3. adopt linear electric motors to drive, the overall efficiency height, noise is little, and the movement velocity pattern is adjustable, and oil production technology such as can realize that long stroke, low jig frequency, big pump are taken out deeply is applicable to the oil extraction of complex hole condition such as heavy oil wells, high-gas-contained well, high wax containing well.
