Abstract
The utility model discloses a prevent air-lock hydraulic feedback oil-well pump is designed for solving the air-lock problem of oil-well pump and improving oil pumping efficiency. An oil outlet valve set and an oil inlet valve set which are connected with a large plunger cylinder and a small plunger cylinder are respectively arranged at the upper part and the lower part in the pump body, and a gas-liquid displacement cavity and a pump cavity are formed between the plunger cylinders and the pump body. The plunger cylinder of the oil well pump carries gas into the gas-liquid displacement cavity to be displaced with oil through an upper stroke and a lower stroke, then the gas is discharged into the oil cavity, and partial gas is discharged once per stroke, so that the oil well pump cannot be locked by gas. The oil well pump provides a rising and discharging channel for gas entering the pump, thereby reducing the gas-liquid ratio in the pump, preventing the air lock of the oil well pump, improving the efficiency of the oil well pump, reducing the labor intensity of frequent bumping of workers and reducing the damage of the oil well pump caused by bumping.
Description
Technical field
The utility model relates to a kind of anti-gas lock fluid power feedback oil well pump, belongs to technical field of petroleum extraction.
Background technique
At the notes that are used for viscous crude production, take out two-purpose pump, fluid power feedback oil well pump is widely used because of having downstream feedback power and can overcoming the descending resistance of rod string.But fluid power feedback oil well pump self does not possess degassing function, and Chang Yin " gas lock " and cause operational failure influence the normal production continuously of oil well.After " gas lock " takes place, can only lean on the artificial terrestrial operation release of " bumping pump ", prolong the oil pumping time, increase hand labor intensity, also can damage oil well pump because of frequent " bumping pump ".
Summary of the invention
The purpose of this utility model is to provide a kind of anti-gas lock fluid power feedback oil well pump, and " gas lock " problem that it can solve conventional feedback oil well pump improves pumping efficiency.
Concrete technological scheme of the present utility model is as follows:
Pump barrel box cupling I internal upper part is the oil pipe chamber, and the bottom connects goes up pump barrel; Last pump barrel lower end connects hollow tube upper-end surface center hole, and hollow tube lower end surface center hole connects pump barrel down; Following pump barrel outer wall bottom connects pump barrel box cupling II, and following pump barrel box cupling inwall bottom connects pump barrel, and pump barrel outer wall bottom connects pump barrel box cupling III.
In set out fuel tap ball and delivery valve seat oil-release valve cover be located in the pump barrel, the valve bonnet sidewall is provided with radial direction through hole, the valve bonnet bottom outlet connects the big plunger tube that runs through in hollow tube center hole and the following pump barrel, the formation gas-liquid is replaced the chamber between hollow tube inwall and the big plunger tube; Establish the oil-feed valve bonnet of oil-feed valve ball and oil-feed valve seat in big plunger drum outer wall bottom connects, the valve bonnet sidewall is provided with radial direction through hole, and the valve bonnet bottom outlet connects the small plunger tube that runs through in the pump barrel tube, forms pump chamber between following pump barrel inwall and oil-feed valve bonnet and the small plunger tube.
This oil well pump provides the passage that rises and discharge for the gas that enters in the pump, thereby can reduce the gas liquid ratio in the pump, prevents the oil well pump gas lock, improves the oil pumping pump efficiency, alleviates the labor intensity of workman's frequent " bumping pump ", reduces and damages oil well pump because of " bumping pump ".
Description of drawings
Fig. 1 is anti-gas lock fluid power feedback oil well pump structural representation.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
This oil well pump is made up of pump barrel box cupling I 1, oil-release valve cover 2, fuel-displaced valve ball 3, delivery valve seat 4, last pump barrel 5, big plunger tube 6, hollow tube 7, following pump barrel 8, oil-feed valve bonnet 9, oil-feed valve ball 10, oil-feed valve seat 11, small plunger tube 12, pump barrel box cupling II 13, pump barrel 14 and pump barrel box cupling III 15:
Pump barrel box cupling I 1 internal upper part is oil pipe chamber A, and lower thread connects upward pump barrel 5; The last pump barrel 5 lower ends hollow tube 7 upper-end surface center holes that are threaded, the hollow tube 7 lower end surface center holes pump barrel 8 that is threaded down; Following pump barrel 8 outer wall bottom thread connect pump barrel box cupling II 13, and following pump barrel box cupling 13 inwall bottom thread connect pump barrel 14, and pump barrel 14 outer wall bottom thread connect pump barrel box cupling III 15.
In set out fuel tap ball 3 and delivery valve seat 4 oil-release valve cover 2 be located in the pump barrel 5, the valve bonnet sidewall is provided with radial direction through hole, the valve bonnet bottom outlet is threaded and runs through big plunger tube 6 in hollow tube 7 center holes and the following pump barrel 8, and the formation gas-liquid is replaced chamber B between hollow tube 7 inwalls and the big plunger tube 6; In being threaded, big plunger tube 6 outer wall bottoms establish the oil-feed valve bonnet 9 of oil-feed valve ball 10 and oil-feed valve seat 11, the valve bonnet sidewall is provided with radial direction through hole, the valve bonnet bottom outlet is threaded and runs through small plunger tube 12 in 14 of the pump barrels, forms pump chamber C between following pump barrel 8 inwalls and oil-feed valve bonnet 9 and the small plunger tube 12.
The working principle of anti-gas lock fluid power feedback oil well pump is as follows:
The oil pumping principle: during upstroke, big plunger tube 6 is up, and it is big that pump chamber C volume becomes, and pressure reduces, and OIH liquid backs down oil-feed valve ball 10, enters pump chamber C through oil-feed valve bonnet 9 radial direction through hole; During down stroke, big plunger tube 6 is descending, pump chamber C smaller volume, and pressure increases, and the fluid in the pump chamber C backs down fuel-displaced valve ball 3 in oil-feed valve bonnet 9 radial direction through hole enter big plunger tube 6, enter oil pipe chamber A through oil-release valve cover 2 radial direction through hole again.
Anti-gas lock principle: during near upper dead center, pump chamber C communicates with gas-liquid displacement chamber B in upstroke, and the gas in the pump chamber C enters gas-liquid and replaces chamber B; Down stroke is during near lower dead centre, and gas-liquid displacement chamber B communicates with oil pipe chamber A, and the oil pipe inner fluid enters gas-liquid displacement chamber B, and the gas in the chamber B of gas-liquid displacement simultaneously enters oil pipe chamber A, and every stroke is discharge section gas all once, makes the oil well pump just can not be by " gas lock ".
