Abstract
The utility model relates to an oil pumping unit, in particular to a single-cylinder hydraulic reciprocating type oil pumping unit. The single-cylinder hydraulic reciprocating type oil pumping unit comprises a hydraulic cylinder, a hydraulic piston and a hydraulic station. The hydraulic cylinder is fixedly arranged on a well mouth in a sitting mode. The number of the hydraulic cylinder is one. The hydraulic piston is arranged in the hydraulic cylinder. The hydraulic piston is connected and fixed with a sucker rod through threads. The sucker rod is connected with an oil well pump. An input pipeline and an output pipeline are arranged between the hydraulic cylinder and the hydraulic station. The single-cylinder hydraulic reciprocating type oil pumping unit has the advantages of being fixed on the well mouth, being small in occupied area and simple in the transmission method, eliminating a large machine body of a huge walking-beam type oil pumping unit, reducing energy loss distributed by mechanical transmission, improving efficiency, and being free of frequent balance adjustment due to the fact that a hydraulic system is adopted to directly eliminate the unbalance phenomenon generated from load changes.
Description
Technical field
The utility model relates to a kind of oil pumper, relates in particular to a kind of single-cylinder hydraulic reciprocating beam-pumping unit.。
Background technology
The high mechanical loss of beam pumping unit cost is large at present, floor space is large, efficient is low, and inertia is unfavorable for greatly controlling, and the balance of whole traditional beam pumping unit just will be affected in case downhole load changes.The phenomenon that runs to topmost and easily freely swing bottom the time at sucker rod, i.e. the oil pumper driving electric machine situation of rotation rapidly.Shorten the life-span of motor or directly damage motor, the disconnected situation of taking off of oil pumper also can occur when serious.
Summary of the invention
Provide a kind of single-cylinder hydraulic reciprocating beam-pumping unit in order to solve the problems of the technologies described above the utility model, purpose is to solve that cost is high, floor space large, big energy-consuming, be not suitable with the problem of load variations.
For reaching above-mentioned purpose single-cylinder hydraulic reciprocating beam-pumping unit, comprise hydraulic cylinder, hydraulic piston and Hydraulic Station, hydraulic cylinder fixedly is sitting on well head, hydraulic piston is one, hydraulic piston is located in hydraulic cylinder, hydraulic piston is connected and fixed by screw thread and sucker rod, and sucker rod is connected with oil well pump, is provided with intake pipeline and export pipeline between hydraulic cylinder and Hydraulic Station.
Hydraulic cylinder is bolted on well head.
Sucker rod between well head below and oil well pump is located in oil pipe.
Hydraulic cylinder is provided with position sensor and pulling force sensor.
The utility model has the advantages of: the utility model is fixed on well head, the little large-scale fuselage that has saved huge beam pumping unit of floor space, the kind of drive has simply reduced the energy loss that machine driving divides and has improved efficient, owing to having adopted hydraulic system directly to eliminate often adjustment of energy imbalance that load variations produces.The low yield oil well that suitable load is lighter.Simple in structure, easy to operate hydraulic piston drives sucker rod and pumps.Sucker rod connecting downhole oil well pump can reach the oil recovery purpose.And being equipped with pulling force sensor and position sensor monitors also and can carry out the intelligence adjusting to the stroke jig frequency as required the operation of oil pumper.
