Abstract
The utility model discloses an oil field efficiency-enhancing special pump. The pump comprises a pump body (1), a connecting rod (2), an air inlet (3), an air outlet (4) and a safety valve (9). The connecting rod (2), the air inlet (3), the air outlet (4) and the safety valve (5), serving as a whole body, are connected to the lower end of the pump body (1). A piston rod (6) is arranged inside the pump body (1), and the piston rod (6) is matched with a piston of the pump body (1). By adopting the structure, since the structure is simple, the additionally provided power drive is not needed. The pump can work only when the pump is arranged on a force arm of an oil exploitation machine. The energy consumption is saved, and the cost is reduced. In addition, a grease cup is arranged on the piston rod so that the pump does not need to be dismounted when lubricant is added, and thus the lubricant addition is more convenient and quicker.
Description
Technical field
The utility model relates to a kind of air extractor of oil field, especially relates to a kind of dedicated pump that is used for oil field synergy.
Background technique
At present, lower or do not have the oil well of casing pressure for casing pressure in the oil well operation, often because gas discharge is not enough, influenced the output of crude oil and rock gas.Casing pressure is the oil well of 0.02Kpa/cm2, and crude oil yield generally has only 0.2 ton/day.Existing oil field synergy dedicated pump is extracted gas out often by a driven by motor extraction pump from sleeve pipe, send into that oil transport pipeline finishes, and this apparatus structure complexity possesses power source, thereby has wasted the energy, has increased cost.
Summary of the invention
The purpose of this utility model provides a kind of oil field synergy dedicated pump, and this oil field synergy dedicated pump is simple in structure, does not need the optional equipment motivational drive.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises the pump housing, connecting rod, suction port, air outlet and safety valve, connecting rod, suction port, air outlet and safety valve are as a whole fastening pump housing lower end that is connected in, be provided with piston rod in the described pump housing, piston rod cooperates with pump housing piston.
Piston rod described in the utility model is provided with lubricating cup.
The said structure that the utility model adopts because simple in structure, does not need the optional equipment motivational drive, just can work as long as be contained on the arm of force of oil pumping unit, has saved energy consumption, has reduced cost yet; In addition, on piston rod, be provided with lubricating cup, make when adding lubricant oil, to need not dismounting, convenient rapid.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing as can be known, this oil field synergy dedicated pump comprises the pump housing 1, connecting rod 2, suction port 3, air outlet 4 and safety valve 5, connecting rod 2, suction port 3, air outlet 4 and safety valve 5 are as the whole fastening pump housing 1 lower end that is connected in, be provided with piston rod 6 in the described pump housing 1, piston rod 6 cooperates with the pump housing 1 piston.As to a kind of improvement of the present utility model, can on described piston rod 6, be provided with lubricating cup 7.During work, as long as with the upper end of piston rod 6 spreading on demand, fastening multi pack is just passable on the arm of force of oil pumping unit.Piston rod 6 is along with the action of the arm of force of oil pumping unit, just in time can cooperate as piston with the pump housing 1, can improve the casing pressure of oil well by continuous operation.When needing to lubricate, only need in lubricating cup 7, to inject lubricant oil.Prove that by experiment former casing pressure is the oil well of 0.02Kpa/cm2, after using this oil field synergy dedicated pump, casing pressure rises to 0.3Kpa/cm2, and crude oil yield increases to 5 tons/day from 0.2 ton/day.
Claims (2)
1, a kind of oil field synergy dedicated pump, comprise the pump housing, connecting rod, suction port, air outlet and safety valve, connecting rod, suction port, air outlet and safety valve are as a whole fastening pump housing lower end that is connected in, it is characterized in that: be provided with piston rod in the described pump housing, piston rod cooperates with pump housing piston.
