Abstract
A kind of gas-liquid displaced type gas prevention pump, belongs to the oil well pump technical field that is subject to gases affect well.The upper pump barrel top connection coupling of oil well pump, upper pump barrel lower end connects upper ventilation lumen joint, upper ventilation lumen joint lower end connects ventilation lumen, ventilation lumen lower end connects lower ventilation lumen joint, and lower ventilation lumen joint is connected with lower pump barrel, and lower pump barrel is connected with standing valve assembly by box cupling, long-plunger top in pump barrel connects upper travelling valve assembly, two tool joint pins upper end is threaded connection linkage connector, and lower end connects upper travelling valve assembly, and long-plunger lower end connects lower travelling valve assembly.The setting that the utility model has the advantages that ventilation lumen has been opened passage to gas in pump, thereby has increased the filling index of liquid in working barrel, has reduced the gas liquid ratio in pump, has got rid of the interference of gas, is conducive to the raising of pump efficiency.
Description
Technical field
The utility model relates to a kind of gas-liquid displaced type gas prevention pump, belongs to the oil well pump technical field that is subject to gases affect well.
Background technique
Oil well gases affect is a reasons that causes pump efficiency low, more harmful, and " liquid hammer " phenomenon often occurs in this oil well, has accelerated the damage of sucker rod, pump valve and valve bonnet.The conventional way that solves gases affect has two kinds, and the one, reduce clearance volume method, this method can not meet high gas-oil ratio (HGOR) oil well production demand completely; The 2nd, gas anchor separation method, the gas-liquid separation completely of this method, gas is by cover tube drainage, the wasting of resources.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of gas-liquid displaced type gas prevention pump.The problem existing for conventional way, the new approaches of casing head gas body impact are proposed to solve, to avoid gas to be left object at pump chamber internal memory, design gas-liquid displaced type gas prevention pump, its feature is exactly in the middle of the pump housing, to be provided with ventilation lumen, this ventilation lumen makes have enough liquid to open traveling valve in pump in the time of down stroke, can solve thoroughly finding time and gas lock phenomenon of pump, improve pump efficiency, have simple in structure, the feature that easy processing cost is low, has effectively alleviated the impact of gas on oilwell produced fluid amount, reaches the object that improves pump efficiency.
A kind of gas-liquid displaced type gas prevention pump, the upper pump barrel top connection coupling of oil well pump, upper pump barrel lower end connects upper ventilation lumen joint, upper ventilation lumen joint lower end connects ventilation lumen, ventilation lumen lower end connects lower ventilation lumen joint, lower ventilation lumen joint is connected with lower pump barrel, lower pump barrel is connected with standing valve assembly by box cupling, long-plunger top in pump barrel connects upper travelling valve assembly, two tool joint pins upper end is threaded connection linkage connector, lower end connects upper travelling valve assembly, and long-plunger lower end connects lower travelling valve assembly.
The setting that the utility model has the advantages that ventilation lumen has been opened passage to gas in pump, thereby has increased the filling index of liquid in working barrel, has reduced the gas liquid ratio in pump, has got rid of the interference of gas, is conducive to the raising of pump efficiency.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously the many modifications and variations that, those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of gas-liquid displaced type gas prevention pump, the upper pump barrel 2 top connection couplings 1 of oil well pump, upper pump barrel 2 lower ends connect changes ventilation lumen joint 6, upper ventilation lumen joint 6 lower ends connect ventilation lumen 8, ventilation lumen 8 lower ends connect lower ventilation lumen joint 9, lower ventilation lumen joint 9 is connected with lower pump barrel 11, lower pump barrel 11 is connected with standing valve assembly 12 by box cupling, long-plunger 7 tops in pump barrel connect upper travelling valve assembly 4, two tool joint pins 5 upper ends are threaded connection linkage connector 3, lower end connects upper travelling valve assembly 4, long-plunger 7 lower ends connect lower travelling valve assembly 10.
When long-plunger 7 is up while leaving lower pump barrel 11, in ventilation lumen 8, liquid falls into lower pump barrel 11, by gas displacement in lower pump barrel 11 to ventilation lumen 8; When plunger is descending, in lower pump barrel 11, liquid is opened traveling valve, and meanwhile, descending plunger 7 is crossed ventilation lumen 8, and in upper pump barrel 2, liquid enters ventilation lumen 8, and gas displacement in ventilation lumen to upper pump barrel 2 and enter oil pipe, is realized to oil gas and polyblends.
When up stroke, long-plunger 7 is up, and standing valve assembly 12 is opened oil-feed, and upper travelling valve assembly 4 and lower travelling valve 10 are closed oil extraction.In the time that long-plunger 7 lower ends are left lower pump barrel 11 and entered ventilation lumen, ventilation lumen 8 is communicated with lower pump barrel 11, and the gas in pump in well liquid rises, until upstroke finishes.
When down stroke, long-plunger 7 moves downward, standing valve is closed standing valve assembly 12, upper travelling valve assembly 4, lower travelling valve assembly 10 are opened fuel-displaced, and in the time that the upper end of long-plunger 7 enters ventilation lumen 8, ventilation lumen 8 is just communicated with oil pipe, at this moment be present on the gas in ventilation lumen 8 and escape, ventilation lumen 8 is full of by well liquid simultaneously, until down stroke finishes, has so just completed a pumping process.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
