Detailed Description
As shown in fig. 1, an embodiment of the present invention provides a multi-parameter mobile measurement device for measuring the hydrocarbon water content in a production fluid discharged through a christmas tree connected to a wellhead, comprising:
the liquid inlet of the liquid inlet pipe 1 is connected with the christmas tree through a quick connector 2;
the jet pump 3 is connected with a liquid outlet of the liquid inlet pipe 1;
a separation tank 4 in which an electric flocculation device 5 is arranged; the electric flocculation device 5 includes: a case 51, a positive electrode 52 and a negative electrode 53 provided in the case 51; the housing 51 has an inlet and an outlet provided at two opposite ends, the inlet being connected to the outlet end of the jet pump 3 through a jet pipe 6 penetrating the side wall of the separation tank 4, the outlet being connected to a first oil storage tank (not shown) through a first oil pipe 7 penetrating the side wall of the separation tank 4, the first oil pipe 7 being provided with an oil flow meter 8; the positive electrode 52 and the negative electrode 53 are provided at positions near the inlet and are respectively located at the top wall and the bottom wall of the case 51; the bottom wall of the housing 51 is also provided with a spillway plate 54 extending vertically upwards into the housing 51, the spillway plate 54 being located between the negative electrode 53 and the outlet; a drain hole 55 is formed in the bottom wall of the shell 51 in a penetrating manner, and the drain hole 55 is positioned between the negative electrode 53 and the overflow weir plate 54;
a flash tank 10 communicated with the bottom of the separation tank 4 through a water pipe 9, wherein the bottom of the flash tank 10 is connected with a second oil pipe 11, and the second oil pipe 11 is connected to a second oil storage tank;
an electric heater 12 provided on the water pipe 9 for heating the liquid in the water pipe 9 to more than 100 ℃;
the condenser 14 is communicated with the flash tank 10 through the flash pipe 13, the outlet end of the condenser 14 is connected with a condenser pipe 15, and the condenser pipe 15 is provided with a water flowmeter 16.
In a further embodiment, the liquid inlet pipe 1 is wrapped with a heating component 17, which is used for heating and reducing the viscosity of the output liquid entering the liquid inlet pipe 1, so that the fluidity is substantially increased. The heating component 17 can adopt an electric heating device, such as a heating wire, which is wound outside the liquid inlet pipe 1 to realize heating.
The liquid inlet pipe 1 is provided with a dosing system 18 for adding a demulsifier into the liquid inlet pipe 1, so that oil and water in the produced liquid are fully mixed to form small liquid drops, and the jet pump 3 can assist in improving the mixing of the oil and the water. Further, a concentration monitoring element 19 for monitoring the concentration of the demulsifier is arranged in the separation tank 4, the concentration monitoring element 19 is a concentration sensor, and is in signal connection with the dosing system 18, so as to realize automatic replenishment dosing according to the concentration of the stored liquid in the separation tank 4.
Specifically, the bottom of the separator tank 4 is connected to the inlet end of the jet pump 3 via a return pipe 20, and the return pipe 20 is provided with an air flow pump 21. Before the separation operation starts, a liquid storage tank 4 is preset in the separation tank for ensuring the normal operation of the jet pump 3. When the separation operation starts, as the oil-water separation of the produced liquid continues, the water in the separation tank 4 (in fact, the water in the separation tank 4 is still mixed with a small amount of oil, which is why the flash tank 10 is arranged behind the separation tank 4) continues to increase, and the air flow pump 21 pumps the water in the separation tank 4 into the jet pump 3 as the jet medium of the jet pump 3, so that the closed circulation is realized, and the self-sufficient separation circulation of the device is realized under the condition of no participation of external medium.
Dosing system 18 includes a control module in signal communication with concentration monitoring element 19, a dosing pump controlled by the control module. When the concentration monitoring element 19 detects that the concentration of the demulsifier in the liquid in the separation tank 4 is lower than the set value, the demulsifier is consumed, the control module controls the start of the dosing pump, and the demulsifier is added into the liquid inlet pipe again.
In this embodiment, the control module may be implemented in any suitable manner. In particular, for example, the control module may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the microprocessor or processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers (Programmable Logic Controller, PLC) and embedded micro control units (Microcontroller Unit, MCU), examples of which include, but are not limited to, the following micro control units: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, silicone Labs C8051F320. It will also be appreciated by those skilled in the art that the control units can be implemented entirely by logic programming method steps to cause the control units to be implemented as logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded micro control units, etc., in addition to the functionality of the control modules being implemented as pure computer readable program code. The control module can transmit data to the mobile phone of the user by means of GRPS, so that remote data can be transmitted in time.
During the above cycle, it is ensured that the liquid level in the separator tank 4 is always maintained at a set level. In view of the above description, in the case of shaving off the stock solution preset in the separation tank 4 at the beginning, the water discharged from the electric flocculation device 5 into the separation tank 4 during the subsequent separation, the water phase pumped by the air flow pump 21, etc., are ideal or desired results. In this way, the water inflow is the same as the water outflow, and the liquid level in the separator tank 4 remains approximately equal all the time.
Therefore, in order to achieve the above object, a liquid level monitoring element 22 for monitoring the liquid level is provided in the separator tank 4, and the liquid level monitoring element 22 is connected to the air flow pump 21. The air flow pump 21 controls the rotation speed of the liquid level in the separation tank 4 based on the liquid level monitoring element 22, and further controls the water outlet speed of the pump.
The liquid level monitoring element 22 is a liquid level sensor, and when the liquid level monitoring element 22 monitors that the liquid level in the separation tank 4 is lower than or higher than a set value, the rotation speed of the air flow pump 21 is correspondingly reduced or increased, so that the pumping speed of water is reduced or increased, and the liquid level in the separation tank 4 is gradually recovered. When the liquid level is restored to the set value, the air flow pump 21 maintains its current rotation speed so that the liquid level in the separator tank 4 is maintained at the current value. Through the above-mentioned real-time monitoring and feedback, the liquid level in the separator tank 4 can be kept in dynamic balance all the time.
From the above, the demulsified output liquid enters the shell 51 of the electric flocculation device 5 through the jet pump 3, and the oil, gas and water three phases in the output liquid are separated by adopting a high-voltage pulse electric flocculation process through the positive electrode 52 and the negative electrode 53 arranged in the shell 51. The top wall of the housing 51 is connected with a gas pipe 23, and the other end of the gas pipe 23 extends to the outside of the separation tank 4 through the top wall of the separation tank 4. The gas pipe 23 is provided with a gas flow meter 24, and the other end is connected with a sampling unit 25, and the sampling unit 25 comprises a sampling bag 251 connected with the gas pipe 23 and a hydrogen sulfide detecting element 252 positioned near the sampling bag 251. The separated gas phase enters the sampling unit 25, is collected by the sampling bag 251 and is subsequently subjected to assay, and the hydrogen sulfide detection element 252 displays and alarms on line in real time. The sampling bag 251 and the hydrogen sulfide detecting element 252 are provided together in the housing 253 of the sampling unit 25.
The bottom of the separating tank 4 is provided with circulating produced water, and the circulating produced water enters the jet pump 3 for recycling through the air flow pump 21. The water separated by the electric flocculation device 5 enters the flash tank 10 for thorough oil-water separation after being heated by the electric heater 12, the produced water enters the condenser 14 for condensation and then is measured, and a small amount of crude oil is discharged from the flash tank 10 and enters the second oil storage tank.
The working principle of the multi-parameter mobile measuring device for the oil well produced liquid in the embodiment of the invention is described as follows:
the produced liquid of the oil well enters the liquid inlet pipe 1, the viscosity of the produced liquid is reduced after the produced liquid is heated, and the fluidity is enhanced. And then the demulsifier added by the dosing system 18 changes the produced liquid into small liquid drops, and the small liquid drops enter the electric flocculation device 5 under the auxiliary action of the jet pump 3. The positive and negative electrodes 53 in the electric flocculation device 5 separate the positive and negative electrodes of the electrode high-voltage power supply, and the three-phase separation of oil, gas and water is realized through a high-voltage pulse electric flocculation process. The gas phase is discharged through the gas pipe 23, the flow of the gas is measured by the gas flowmeter 24, and is collected by the sampling bag 251 for subsequent tests, and the hydrogen sulfide detection element 252 detects whether gas leakage exists, so that the safety of equipment is ensured.
The separated oil and water is then temporarily stored in the space to the left of the overflow weir 54. Since the density of water is greater than the density of oil, water is in the lower layer and oil is in the upper layer. After the upper layer of oil exceeds the overflow weir plate 54, the oil overflows to the space on the right side of the overflow weir plate 54, is discharged through the first oil pipe 7, and is measured in flow by the oil flow meter 8. The water flows into the separation tank 4 through the drain hole 55 and flows into the water pipe 9, and is heated to 100 ℃ or higher (typically 103 ℃) by the electric heater 12. Subsequently, the heated water enters the flash tank 10, and the water is flashed, and the oil remains in a droplet state due to the difference in boiling point of the oil and water. So that the water becomes flash steam and enters the condenser 14, the oil is deposited at the bottom of the flash tank 10 and finally discharged through the second oil pipe 11 and metered (the second oil pipe 11 may be provided with an oil flow meter for metering the discharged oil content as well). The flash steam entering the condenser 14 is condensed and then re-condensed into liquid water, which is discharged through a condensing pipe 15 and the flow rate of which is measured by a water flow meter 16. Thus, the measurement of the oil, gas and water three phases in the produced liquid is completed.
Therefore, the invention realizes the separation of oil, gas and water of the produced liquid by arranging the electric flocculation device 5 and adopting a high-voltage pulse electric flocculation process, and realizes the thorough separation of the oil and the water by heating the separated water to more than 100 ℃ and then flashing, thereby ensuring that the metering of the oil and the water is more accurate.
In addition, the embodiment of the invention realizes the detachable connection with the Christmas tree through the quick connector, thereby realizing the movable measurement of the produced liquid of the oil well and having better convenience. And moreover, the content of oil gas and water in the produced fluid can be measured simultaneously through one-time operation, and the measurement efficiency is higher.
The foregoing is merely a few embodiments of the present invention and those skilled in the art, based on the disclosure herein, may make numerous changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the invention.
