The piston divides each oil cylinder into an oil cylinder upper cavity and an oil cylinder lower cavity, and both ends of the hydraulic oil pipe are respectively connected with every two adjacent oil cylinder lower cavities. The utility model implements balance among multi-well loads by using the multi-well or double-well machine, thereby implementing efficient production and satisfying the demand of energy-saving consumption-reduction production for the multiwell cluster and infill well cluster.
Description
Technical field
The utility model relates to oil rig, specifically hydro-cushion oil rig between a kind of well factory well.
Background technology
" well factory " is widely used in a kind of mass of petrol resources exploitation, intensive exploitation theory or pattern both at home and abroad at present, but reducing development cost, increases economic efficiency.At present, " well factory " theory is multiplex in the operations such as the drilling well of cluster well group, completion, pressure break." well factory " oil well well spacing is nearer, suitable unification engine twin-well or gang pumping, but the still individual well oil pumping that the oil field is commonly used at present.Not only efficient is low for the individual well oil pumper, cost is large, and energy loss is serious, has not satisfied the needs of current oil exploitation.
For this reason, carried out the research of many wells or twin-well pumping technology both at home and abroad since the eighties in last century, mainly contained abroad the U.S. and Russia, domestic have the large Khanh Hoa Liaohe River, but all be in the development phase, can only use at offset well, and the well spacing bad adaptability.
Summary of the invention
The purpose of this utility model provides a kind of machine that makes between many wells or twin-well and realizes each other balance of many wells load, thereby realize High-efficient Production, cost, energy-saving and cost-reducing design object, satisfy the cluster well group and encrypt hydro-cushion oil rig between the well factory well of the energy-saving and cost-reducing exploitation of well group needs.
The purpose of this utility model can be achieved by the following technical measures:
The hydro-cushion oil rig comprises the reciprocating type oil cylinder of at least two covers between this well factory well, every suit oil cylinder is corresponding with independent separately oil well, described reciprocating type oil cylinder comprises oil cylinder and is arranged on the piston of oil cylinder inside and reciprocating type stretching motion, described piston lower end connects oil pumping polish rod by piston rod, and oil pumping polish rod connecting downhole roofbolt load, described all reciprocating type oil cylinders interconnect by hydraulic oil pipe, are provided with two-way hydraulic motor or bidirectional hydraulic pump on the described hydraulic oil pipe.
The purpose of this utility model also can be achieved by the following technical measures:
Described piston is divided into cylinder upper cavity oil chamber and oil cylinder lower chambers to oil cylinder, and described hydraulic oil pipe two ends are connected with adjacent two oil cylinder lower chambers respectively; The hydraulic oil that drives usefulness is housed in above-mentioned two lower chambers that are communicated with and hydraulic oil pipe; Described two-way hydraulic motor is connected with motor, the operation of Motor Drive two-way hydraulic motor; Described bidirectional hydraulic pump is connected with motor, Motor Drive bidirectional hydraulic pump operation.
The utlity model has following beneficial effect:
1, load balance each other between well has reduced moving-mass, has reduced inertial load, and energy-saving effect is remarkable;
2, cancelled accumulator or counterweight, reliability is high, and cost of investment is low.
3, two wells needn't be adjacent well, and the well spacing strong adaptability.
Description of drawings
Fig. 1 is the structure principle chart of the utility model embodiment.
Among the figure: the first oil well 1, the second oil well 2, the first oil cylinder 3, the second oil cylinder 4, first piston 5, the second piston 6, the first polished rod 7, the second polished rod 8, oil pipe 9, two-way hydraulic motor or bidirectional hydraulic pump 10, motor 11.
The specific embodiment
Referring to shown in Figure 1, the first oil cylinder 3 and first piston 5 form the reciprocating type oil cylinder of first set of the first oil well 1, and the second oil cylinder 4 and the second piston 6 form the reciprocating type oil cylinder of the second cover of the second oil well.The first polished rod 7 tops connect with first piston 5, and the bottom connects the first oil well 1 down-hole roofbolt load, and the second polished rod 8 tops connect with the second piston 6, and the bottom connects oil well 2 down-hole roofbolt load.Two-way hydraulic motor 10 connects respectively the lower chambers of the first oil cylinder 3, the second oil cylinder 4 by oil pipe 9, and motor 11 is as 10 operations of power drive two-way hydraulic motor.
The course of work of the present utility model is: when the first oil well 1 is descending, first piston 5 is under the roofbolt load, produce high pressure in the first oil cylinder 3 bottom chamber, promote to drive liquid and provide auxiliary torque by 9 pairs of two-way hydraulic motors 10 of oil pipe, cooperate motor 11, with the driving liquid of the first oil cylinder 3 lower chambers, be pumped into the lower chambers of the second oil well 2 second oil cylinders 4, it is up to drive the second oil well 2; When the first oil well 1 arrived bottom dead centre, control system control motor 11 drove two-way hydraulic motor 10 counter-rotatings, and the first oil well 1 becomes up, and the second oil well 2 becomes descending; At this moment, the second piston 6 is under the roofbolt load, produce high pressure in the second oil cylinder 4 bottom chamber, promote to drive liquid and provide auxiliary torque by 9 pairs of two-way hydraulic motors 10 of oil pipe, cooperate motor 11, with the driving liquid of the second oil cylinder 4 lower chambers, be pumped into the lower chambers of the first oil cylinder 3 of the first oil well 1, it is up to drive the first oil well 1.Thus, by two-way hydraulic motor, load balance each other drives polished rod and moves reciprocatingly between well between two well wells, realizes the production of normally pumping of each well.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
