Abstract
A pump-cylinder-enhanced small-pump-diameter whole cylinder oil well pump is mainly composed of a plunger open valve cover, traveling valve balls, traveling valve bases, a plunger closed valve cover, a plunger valve cover connector, pump connectors, righting rings, a short pump cylinder, a long plunger, a pump outer cylinder, a lower pump cylinder and an oil inlet valve. The pump-cylinder-enhanced small-pump-diameter whole cylinder oil well pump is characterized in that the two sets of traveling valve balls and traveling valve bases are arranged in the plunger open valve cover and the plunger closed valve cover respectively, internal threads at the lower end of the plunger open valve cover are connected with the plunger closed valve cover, the plunger closed valve cover is connected with the plunger valve cover connector which is connected with the upper end of the long plunger, and no traveling valves are arranged at the lower end of the long plunger; internal threads are arranged at the two ends of the pump connectors, and the two ends of the pump outer cylinder are connected with the pump connectors respectively. According to the pump-cylinder-enhanced small-pump-diameter whole cylinder oil well pump, downhole crude oil can be lifted, the strength and the stiffness of the pump cylinders are improved, bending and deformation of the pump cylinders in the transport and use processes of the oil well pump are reduced, the pump inspection period of a production oil well is prolonged, and production cost is lowered.
Description
Technical field
The utility model relates to petroleum industry mechanical oil recovery field, particularly the reinforced small pump diameter integeral tube pumping pump of a kind of pump barrel.
Background technique
At present, at low permeability oil field, along with Oil in Super-low Permeability block large size exploitation, individual well production fluid amount low with the large unmatched contradiction of pump displacement.In recent years, along with the large-scale popularization of Φ 28mm small pump diameter oil well pump is used, alleviation to a certain degree large the and low unmatched contradiction of individual well production fluid amount of pump displacement, but for the lower abandoned wells of production fluid amount, large and the low unmatched contradiction of individual well production fluid amount of pump displacement still exists, therefore, also need to promote the use of the less integeral tube pumping pump in pump footpath to improve pump efficiency, extend the working life of oil well pump.
Chinese patent ZL99207197.6 solid plunger oil pump has proposed the oil well pump of solid plunger structure, the pump footpath of oil well pump further can be dwindled, thereby pump displacement is mated more with the production fluid amount of oil well.
But solid plunger structure oil well pump exists the pump lower end cannot supporting hammering oil discharger; In pump dirty cannot excavationg pump outside, easily oil flow channel in block pumps; The pump barrel of small pump diameter is difficult to the problems such as processing, has had influence on promoting the use of of solid plunger oil pump.
The integeral tube pumping pump that 2 0746297.2 one kinds of integeral tube pumping pumps of Chinese patent ZL2012 have proposed long-plunger short pump barrel structure preferably resolves the deficiency that solid plunger oil pump exists aspect small pump diameter oil well pump Design and manufacture, the application of small pump diameter oil well pump is obtained further and promote.But the small pump diameter integeral tube pumping pump of long-plunger short pump barrel structure is because Diameter of pump tube is less than normal, rigidity and intensity difference, easily bend in transport with in using, the problem such as distortion, causes oil well pump normally to work.
Summary of the invention
The purpose of this utility model is: provide a kind of pump barrel reinforced small pump diameter integeral tube pumping pump, can realize hoisting of downhole crude, improve the strength and stiffness of pump barrel, reduce the generation of oil well pump pump barrel bending in transport and use, problem on deformation, the pump detection period that extends production well, reduces production costs.
The technical solution of the utility model is, the reinforced small pump diameter integeral tube pumping pump of a kind of pump barrel, mainly by plunger open type valve cover, valve ball moves about, valve seat moves about, plunger closed cage, plunger valve shield joint, pump joint, righting circle, short pump barrel, long-plunger, pump urceolus, lower pump barrel, oiling valve composition, it is characterized in that: two overlap the valve ball that moves about is placed in respectively in plunger open type valve cover and plunger closed cage with the valve seat that moves about, the internal thread of plunger open type valve cover lower end is connected with plunger closed cage, plunger closed cage is connected with plunger valve shield joint, plunger valve shield joint is connected with the upper end of long-plunger, long-plunger lower end is without traveling valve, there is internal thread at the two ends of pump joint, connect respectively a pump joint at the two ends of pump urceolus, have short pump barrel and lower pump barrel in pump urceolus internal sleeve, one end of short pump barrel and lower urceolus interconnects by screw thread, the other end by end face respectively with the interior edge face press seal of pump joint, in annular space between pump urceolus and short pump barrel and lower pump barrel, have righting circle, righting circle is socketed on respectively on short pump barrel and lower pump barrel, on the pump joint of pump urceolus lower end, be connected with oiling valve.
The beneficial effects of the utility model: the reinforced small pump diameter integeral tube pumping pump of a kind of pump barrel of the utility model, can realize hoisting of downhole crude, improve the strength and stiffness of pump barrel, reduce the generation of oil well pump pump barrel bending in transport and use, problem on deformation, the pump detection period that extends production well, reduces production costs.
