Abstract
The oil well gas-liquid mixture conveyer consists of gas-liquid mixture conveying pump and gas-liquid separator connected via pipes. Oil well gas-liquid mixture entered by the inlet pipe is pressure raised in the pump before entering the gas-liquid separator by the outlet pipe. Partial liquid from the gas-liquid separator is returned via the lower outlet and reflux pipe to the inlet of the gas-liquid mixture conveying pump, and the separated gas and the other part of the liquid are output via the upper outlet and outer pipe. The reflux liquid flow rate is adjusted by the adjusting valve. The present invention has lowered gas/liquid ratio into the pump to avoid gas lock and to ensure the normal operation of the pump.
Description
Technical field
The present invention relates to a kind of device that is used to carry oil well gas-liquid mixture.
Background technique
In the oil field operation, the fluid that pumping goes out from oil well is a kind of mixing gas-liquid that is mixed with water and rock gas, and its gas liquid ratio (volume ratio of promptly mixing gas phase and liquid phase in the gas-liquid) is constantly to change.In the prior art, the mixing gas-liquid of oil well output is delivered to transfer station or Combined Treatment station after generally directly utilizing gas fluid mixture pump to boost.Above-mentioned gas fluid mixture pump is a kind of by the pump housing and the displacement pump that is installed in the pump housing and parts such as engaged screw rod and mechanical seal constitute, and it utilizes the mode of axial compression that the mixing gas-liquid is boosted.When the gas liquid ratio that mixes gas-liquid raises when more (contain gas), be easy to form vent plug in the pump housing of gas fluid mixture pump, make the mechanical seal and the screw rod of gas fluid mixture pump produce dry friction and a large amount of heating, and then cause the damage of mechanical seal and leakage of oil occurs or cause screw rod to damage and pump efficiency is sharply descended, when serious even can cause whole gas fluid mixture pump to damage fully and can't work.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of oil well gas-liquid mixing conveyance, preventing forming vent plug in gas fluid mixture pump, thereby guarantees the proper functioning of gas fluid mixture pump.
To achieve these goals, the present invention sets up a gas-liquid separator and makes a part of liquid that gas-liquid separator separates goes out be transmitted back to the import of gas fluid mixture pump by the following outlet of gas-liquid separator through reflux pipeline in the outlet line of existing gas fluid mixture pump, the gas that gas-liquid separator separates goes out and another part liquid are then exported through external transport pipeline by the upper outlet of gas-liquid separator.
In above-mentioned oil well gas-liquid mixing conveyance, can effectively reduce the gas liquid ratio of the mixing gas-liquid that enters in the gas fluid mixture pump from the reflux liquid of gas-liquid separator, even when the gas liquid ratio of oil well gas-liquid mixture raises, still can avoid forming vent plug in the gas fluid mixture pump, thereby guarantee the proper functioning of gas fluid mixture pump.
Be described in further detail below in conjunction with the technical characteristics of specific embodiment oil well gas-liquid mixing conveyance of the present invention.
Four, description of drawings
Fig. 1 is the schematic representation of oil well gas-liquid mixing conveyance of the present invention.
Fig. 2 and Fig. 3 are the positive view and the A-A sectional views of slack tank formula gas-liquid separator.
Five, embodiment
As Figure 1-3, oil well gas-liquid mixing conveyance of the present invention mainly utilizes pipeline to connect and compose by gas fluid mixture pump and gas-liquid separator.The advancing of slack tank formula gas-liquid separator 6 that the top is provided with safety valve 12 4 is communicated with the outlet line 7 of gas fluid mixture pump 2, the following outlet 8 of gas-liquid separator 5 links to each other with the inlet line 1 of gas fluid mixture pump 2 by reflux pipeline 11, is provided with solenoid valve 9 and modulating valve 10 in the reflux pipeline 11.
When the present invention works, the mixing gas-liquid of oil well output is entered gas fluid mixture pump 2 and entered gas-liquid separator 5 by outlet line 3 after gas fluid mixture pump 2 boosts by inlet line 71, gas-liquid separator 5 isolated a part of liquid go out 8 by gas-liquid separator 5 following and are transmitted back to the import of gas fluid mixture pump 2 through reflux pipeline 11, gas-liquid separator 5 gas separated and another part liquid then by the upper outlet 6 of gas-liquid separator 5 through external transport pipeline 7 outputs.The flow of withdrawing fluid can be determined and utilizes modulating valve 10 to regulate according to the output situation of oil well; When gas fluid mixture pump 2 stalls, solenoid valve 9 will cut out automatically, to prevent to cause because of reflux liquid the inlet line 1 pressure rising of gas fluid mixture pump 2.
In sum as can be known, the present invention is simple in structure, easy to connect, can effectively reduce the gas liquid ratio of the mixing gas-liquid that enters gas fluid mixture pump, prevents to form vent plug in the gas fluid mixture pump, thereby guarantees the proper functioning of gas fluid mixture pump.Therefore, the present invention is specially adapted to carry oil well gas-liquid mixture.
Claims (3)
1, a kind of oil well gas-liquid mixing conveyance that comprises gas fluid mixture pump, it is characterized in that being provided with a gas-liquid separator in the outlet line of described gas fluid mixture pump, a part of liquid that gas-liquid separator separates goes out exports under gas-liquid separator and reflux pipeline is transmitted back to the gas-liquid delivery pump inlet, and the gas that gas-liquid separator separates goes out and another part liquid are then through gas-liquid separator upper outlet and external transport pipeline output.
2, oil well gas-liquid mixing conveyance according to claim 1, the modulating valve that it is characterized in that being provided with solenoid valve in the described reflux pipeline He be used to regulate the reflux liquid flow.
