Abstract
An oil production device using flexible sucker rod comprises a ground driving device, a well head device, an underground fuel tube, a pumping rod and an oil-well pump. The pumping rod driving device is a roller hoisting unit, the pumping rod is a flexible lever, and the oil-well pump is a single circulating pump. The roller lifting apparatus comprises a machine frame, an electromotor, a decelerator, a sheave, a roller, a flexible lever and two connectors. Wherein, the electromotor, the decelerator, the sheave, the roller and the flexible lever are provided on the machine frame, one connector is arranged between the electromotor and the decelerator, and the other connector is arranged between the decelerator and the roller. One part of the flexible lever is enwound on the roller, and the other part is connected with the single circulating pump in the underground fuel tube through the sheave and the well head device. The oil extraction device adopts the oil extraction manner that roller hoisting driving flexible rod and the oil-well pump do reciprocating motion from the fuel tube bottom to the well head. The scale formation and paraffin deposit are not easy to happen, which reduces the amount of work of cleaning and preventing the dirt and the wax. The pump can be lifted to the well head for repairing conveniently. In particular, the start of the oil pumping is easy, which can realize intermittent pumping.
Description
Technical field
The utility model relates to a kind of plant equipment of oil well oil pumping.
Background technology
Well recovery mode on the present oil field, the overwhelming majority are to use the extracting device of oil of beam type rigidity sucker rod.This device is made up of ground sucker rod drive unit, wellhead assembly, down-hole oil tube, rigidity sucker rod and oil well pump, and rigidity oil pick-up tube during work in the sucker rod drive unit drive beam hanger and oil pump pump and finish oil pumping process.
This weak point that has public oil rig now is:
1, the haul distance of beam hanger is restricted.Can only move back and forth in oil pipe focal length section.Therefore, the easy fouling of inside pipe wall.Clear antiscale, anti-clearly cured work operations amount are big, the expense height.
2, the rigidity sucker rod unloads, the packing technique difficulty is big, complexity, and it is inconvenient to take out the oil pump maintenance.
3, fluid stops to flow to cause to open taking out difficulty when avoiding resting, and though in the oil pipe fuel delivery what, the general frequent start of equipment, the invalid serious wear of waste of energy and equipment like this.For the stripper well of down-hole supply capability, be difficult to adopt the mode of production of intermittent pumping less than pump discharge opeing ability.
The utility model content
The technical problems to be solved in the utility model is the deficiency that overcomes above-mentioned existing extracting device of oil, a kind of extracting device of oil that uses flexible rod is provided, its adopt cylinder elevator drive flexible rod together with oil well pump from the oil pipe bottom to the reciprocating oil production method of well head.Less scaling and the paraffin wax deposition of tube inner wall reduces clear antiscale, anti-clearly cured workload; Can easily pump be promoted to wellhead maintenance.Particularly this mode is pumped to open and is taken out easily, can realize intermittent pumping.
The extracting device of oil of the use rods that provides according to the utility model, it is by ground sucker rod drive unit, and wellhead assembly and down-hole oil tube and sucker rod and oil well pump are formed, and the sucker rod drive unit is the cylinder winding plant, sucker rod is a rods, and oil well pump is the single current pump; Described cylinder winding plant is by frame and be installed on motor, reducer, pulley, cylinder, rods and motor on the frame and the connector between connector, reducer and cylinder between reducer is formed; The part of described rods is wrapped on the cylinder, and another part enters in the down-hole oil tube through pulley, wellhead assembly and is connected with the single current pump.
The extracting device of oil of the use flexible rod that provides according to the utility model also has following attached technical characterictic:
In a kind of scheme that the utility model provides, described rods is a wire rope.
In the another kind of scheme that the utility model provides, described rods is a steel band.
In above-mentioned two kinds of schemes, described reducer is gear reduction unit or worm type of reduction gearing; Also can be belt reducer or chain reducer.
Connector between described reducer and cylinder is coaxial connector or chain link remover.
Connector between described motor and reducer is belt connector or chain link remover or coaxial connector
The utility model has following advantage compared to existing technology:
1, flexible rod can curl, and the specific rigidity pole technology requires low, easy to loading and unloading.
2, flexible rod specific rigidity bar reciprocating motion length is long, can carry out from the shaft bottom to the oil pumping operation of well head.
3, oil well pump can be dragged to wellhead maintenance by rods, needn't go up operation troop and trip out the rigidity rod string, can save a large amount of inspection pump expenses.
4, by whole oil pipe, operating distance is long, makes the paraffin wax in the oil be difficult to deposit on tube inner wall in oil pumping process for pump, can save clear antiscale and clear anti-cured expense.
5, it is empty finishing in each reciprocal back oil pipe in the oil pumping operation, does not have crude oil condensation problem in pipe.Stripper well to the feed flow deficiency can be realized intermittent pumping.Therefore energy conservation reduces production costs significantly.
