Description
Technical field
This utility model relates to a kind of multifunctional oil-well pump.
Background technology
Along with oil exploitation enters the intermediary and later stages, oil well condition becomes increasingly complex, harshness.In the pumpingh well that shakes out, it may appear that sand grains worn piston and pump barrel, pump efficiency is caused to decline, oil well pump service life reduction, sand card phenomenon occurs time serious.For the oil well big at oil-gas ratio, fluid full level is poor, and pump efficiency is low, sometimes there is also gas lock, makes oil well pump normally to work.For inclined shaft, it may appear that valve ball is closed delayed, will also result in plunger and increase with pump barrel frictional force, make plunger to move.
For the machine-pumped oil well of above-mentioned Complex Blocks, when using conventional oil well pump exploitation, the faults such as sand card, gas lock often occur, simultaneously as the impact such as hole deviation, cause valve to close not in time, reduce pump efficiency, affect yield, increase cost for oil production.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of multifunctional oil-well pump.
For solving above-mentioned technical problem, this utility model one multifunctional oil-well pump, including pump barrel joint, pump barrel, the assembly for plunger being placed in pump barrel and the standing valve assembly being loaded on pump barrel lower end；Described assembly for plunger has plunger, and the upper end of plunger is connected with oil-release valve cover, lower end is connected with lower travelling valve, and lower travelling valve includes lower travelling valve seat, lower travelling valve ball and lower contact, and lower travelling valve is threadeded with described plunger lower end to move valve seat downstream；Described standing valve assembly includes oil-feed valve bonnet, the upper end of oil-feed valve bonnet is connected with delivery connection by connecting tube, lower end is connected with standing valve lower contact, in oil-feed valve bonnet, there is fixed valve ball, the inwall of oil-feed valve bonnet has fixed valve base, described assembly for plunger also includes that two ends have externally threaded pull bar, this pull bar sequentially passes through described oil-release valve cover, plunger and lower travelling valve seat and threadeds with described lower travelling valve ball and lower contact, and the pull bar threaded upper ends of assembly for plunger is rotary with top connection.
Using the multifunctional oil-well pump of said structure, the lower travelling valve of assembly for plunger is to be driven pull bar machinery to open and close by sucker rod, changes the delivery valve of tradition oil well pump by the fluid pressure opening/shutting mode in pump.During upstroke, sucker rod drives and moves on pull bar, and lower travelling valve is closed, and the fluid of plunger upper part is given rise to ground, and plunger lower pumping chamber is oil-filled simultaneously；During down stroke, sucker rod drives pull bar to move down, and promotes plunger descending, is opened by force by valve, and the gas mixture of pump cavity of resorption can enter oil pipe by plunger smoothly, thus reaches the effect of gas-tight.It addition, the pull bar of assembly for plunger and plunger are floating connections, can relatively rotate, make plunger wear uniform, improve wearability.
It is screwed union as improvement of the present utility model, described top connection and lower contact.At upper and lower stroke liquid stream by producing spiral flow after upper and lower screwed union, improve whole liquid stream and carry the ability of sand, beneficially sand along outside the helicla flute excavationg pump of screwed union.
As further improvement of the utility model, described assembly for plunger is made up of first paragraph assembly for plunger, second segment assembly for plunger and three sections of assembly for plunger of the 3rd section of assembly for plunger, second segment assembly for plunger is threadeded with the lower contact of first paragraph assembly for plunger with the threaded upper ends of its pull bar, and the 3rd section of assembly for plunger is threadeded with the lower contact of second segment assembly for plunger with the threaded upper ends of its pull bar.The frictional force using three stage ram assembly can solve owing to hole deviation causes increases the problem making plunger to move.
