Description
One, technical field
The present invention relates to oil exploitation, coal-bed gas exploitation apparatus field, especially relate to a kind of cluster well extended-range oil pumper.
Two, background technology
The application of China's cluster well in oil gas field, coal-bed gas exploitation in recent years obtained development fast.The characteristics of cluster well pumping technology: can satisfy some special requirement on the drilling engineering, as the well of speedily carrying out rescue work of uniform blowout; Can accelerate oilfield prospecting developing speed, save drilling cost; Help saving oil field land occupation area, better protection is ploughed and energy conservation; Be convenient to the centralized management of oil well after the completion, reduce gathering and transferring process, save the investment of human, financial, and material resources, and then improve low-permeability oil gas field development economic benefit or the like.But the mechanical oil recovery technology of cluster well is still very backward, does not also have a kind of feasible cluster well oil extractor so far.Present oil field and the coal-bed gas exploitation field exploitation pattern that still uses the unit list to adopt, the equipment input of oil well and normal operating cost are very high, cause the economic benefit of oil well production very low, have in addition approach zero.Main cause is exactly that the unit list is adopted the cluster well characteristics that can not satisfy many wells shared platform.
How to make full use of the little characteristics of cluster well well spacing, realize that a motor drags many mouthfuls of adjacent oil wells and recovers the oil simultaneously, satisfy the cluster wells production arts demand to greatest extent, conservation of power consumes, improve the application life and the pumping efficiency of oil pumper and oil pumping system, domestic and international many experts and scholars carried out deep research and had obtained relevant achievement.At present, domestic had some achievements in research at the specific technique aspect many well interlock oil recoveries of cluster well, but also existing many technical problems aspect oil recovery design for scheme and the reliability, therefore also do not obtain real practical application.
Three, summary of the invention
Technical problem to be solved by this invention is the problem that exists in the above-mentioned cluster well production technique, a kind of cluster well extended-range oil pumper is provided, realize that a motor drags many mouthfuls of adjacent oil wells and recovers the oil simultaneously, its compact conformation, safe and reliable during work, balance is good, and energy-saving effect is remarkable.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cluster well extended-range oil pumper, comprise motor, the belt gear that is connected and is driven by it with described motor, be connected the reducer on the output shaft of described belt gear, be connected on the output shaft of described reducer and drive the crank that rotates by this reducer, be connected the connecting rod on the crank, the slide block that is connected with connecting rod, can be for the guide rail of slide block slip, the chain that links to each other with described slide block two ends, the sprocket wheel that is meshed with described chain, and frame, it is characterized in that: sprocket wheel twines coaxial connection of wheel with steel cable, described steel cable twines many group steel cables is installed on the wheel, organizes steel cable more and passes through directive wheel, head sheave is connected with sucker rod with Rope rod connector.Motion driving sliding block by crank and connecting rod is slided on guide rail, the chain that is connected on the slide block moves with slide block, engaged transmission drive sprocket by chain and sprocket wheel rotates, sprocket wheel drives coaxial steel cable simultaneously and twines wheel rotation together, and many groups steel cable that steel cable twines on the wheel pumps by directive wheel, day wheel drive Rope rod connector and sucker rod.
Described steel cable twines the diameter of the diameter of wheel greater than sprocket wheel.
Described many group steel cables can be chain or belt.
Described guide rail is rail plate or rolling guide.
Described slide block adopts slide block or roller structure.
Described sprocket wheel and steel cable twine the two ends that wheel is installed in guide rail.
The present invention compared with prior art has the following advantages:
1, system effectiveness height.Realize that a motor drags many mouthfuls of adjacent oil wells and recovers the oil simultaneously.
2, the mutual balance sysmte of dual formula.Use the mutual balance mode of oil well and realize the balance of oil pumper, counterbalance effect is fine.
3, complete machine is in light weight.The not additional balance weight of whole oil pumper.
4, installed power is low.The cluster well oil extractor needed power that recovers the oil just is used for overcoming the resistance of motion and the uneven part required drive of antithesis oil well, and required power is very little.
5, energy-saving and cost-reducing.Adopt with respect to the unit list, unit is adopted more because system effectiveness improves, installed power significantly reduces, oil pumper load becomes the minor swing form, makes that the oil pumper energy consumption has obtained reducing significantly.
6, cost for oil production is low.Since the minimizing of weight, the many mouthfuls of shared cover power set of oil well, the equipment investment expense is lower, and cost for oil production reduces significantly.
7, the transportation of oil pumper and mounting cost are low.
