Detailed Description
As shown in fig. 1, an embodiment of the present invention provides a multi-parameter mobile measurement apparatus for oil well production fluid, for measuring oil, gas and water content in production fluid discharged through a christmas tree connected to a wellhead, comprising:
the liquid inlet pipe 1 is connected with the Christmas tree through a quick connector 2;
the jet pump 3 is connected with the liquid outlet of the liquid inlet pipe 1;
a separation tank 4, in which an electric flocculation device 5 is arranged; the electrocoagulation device 5 includes: a case 51, a positive electrode 52 and a negative electrode 53 provided inside the case 51; the housing 51 has an inlet and an outlet at two opposite ends, the inlet is connected with the outlet end of the jet pump 3 through a jet pipe 6 penetrating the side wall of the separation tank 4, the outlet is connected to a first oil storage tank (not shown) through a first oil pipe 7 penetrating the side wall of the separation tank 4, and an oil flow meter 8 is arranged on the first oil pipe 7; the positive electrode 52 and the negative electrode 53 are disposed near the inlet, respectively on the top wall and the bottom wall of the case 51; the bottom wall of the shell 51 is also provided with an overflow weir plate 54 vertically extending upwards into the shell 51, and the overflow weir plate 54 is positioned between the negative electrode 53 and the outlet; a draining hole 55 is arranged on the bottom wall of the shell 51 in a penetrating way, and the draining 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 ℃;
and a condenser 14 communicated with the flash tank 10 through a flash pipe 13, wherein the outlet end of the condenser 14 is connected with a condensing pipe 15, and the condensing pipe 15 is provided with a water flow meter 16.
In a further embodiment, the liquid inlet pipe 1 is wrapped with a heating assembly 17 for heating the produced liquid entering the liquid inlet pipe 1 to reduce viscosity, thereby substantially increasing fluidity. The heating assembly 17 may be an electric heating device, such as a heating wire, wound outside the liquid inlet pipe 1 to achieve heating.
The liquid inlet pipe 1 is provided with a dosing system 18 for adding a demulsifier into the liquid inlet pipe 1 to ensure that oil and water in the produced liquid are fully mixed to form small droplets, and the jet pump 3 can assist in improving the mixing of the oil and the water. Further, be equipped with the concentration monitoring element 19 that is used for monitoring demulsifier concentration in the knockout drum 4, concentration monitoring element 19 is concentration sensor, with charge 18 signal connection of system for according to the stock solution concentration in the knockout drum 4, realize automatic supplementary medicine that adds.
Specifically, the bottom of the separation tank 4 is connected to the inlet end of the jet pump 3 through a return pipe 20, and an air flow pump 21 is provided on the return pipe 20. Before the separation operation starts, a liquid storage is preset in the separation tank 4 for ensuring the normal operation of the jet pump 3. When the separation operation is started, as the oil-water separation of the produced liquid is continuously carried out, 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 also the reason for arranging the flash tank 10 behind the separation tank 4 in the device) is continuously increased, and the air flow pump 21 takes the water pump incident flow pump 3 in the separation tank 4 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 that no external medium participates.
The dosing system 18 comprises a control module in signal connection with the concentration monitoring element 19 and 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 a set value, indicating that the demulsifier is consumed, the control module controls the dosing pump to be started, and the demulsifier is added into the liquid inlet pipe again.
In this embodiment, the control module may be implemented in any suitable manner. Specifically, 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, an Application Specific Integrated Circuit (ASIC), a Programmable Logic Controller (PLC), and an embedded micro-Controller Unit (MCU), examples of which include, but are not limited to, the following: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F 320. It will also be appreciated by a person skilled in the art that instead of implementing the functionality of the control module in the form of pure computer readable program code, it is entirely possible to logically program the method steps such that the control unit implements the same functionality in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded micro control units, etc. The control module can transmit data to the mobile phone of the user by means of GRPS, and 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 kept at a set level. As described above, in the case of removing the stock solution preset in the separation tank 4 from the beginning, the water discharged from the electrocoagulation device 5 into the separation tank 4, the water pumped by the air pump 21, and the like are desirable or desired results in the subsequent separation process. Thus, the water inflow is the same as the water outflow, and the liquid level in the separation tank 4 remains approximately equal throughout.
Therefore, in order to achieve the above object, a liquid level monitoring element 22 for monitoring the liquid level is provided in the separation tank 4, and the liquid level monitoring element 22 is connected to the air flow pump 21. The air pump 21 controls the rotation speed of the separator 4 based on the level of the liquid in the separator 4 monitored by the liquid level monitoring unit 22, and thus controls the speed of the pumped water.
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 rotating 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 restored. When the liquid level height returns to the set value, the air flow pump 21 maintains its current rotational speed to maintain the liquid level height in the separation tank 4 at the current value. By the above real-time monitoring and feedback, the liquid level in the separation tank 4 can be kept in dynamic balance all the time.
As can be seen from the above, the produced fluid after demulsification enters the shell 51 of the electric flocculation device 5 through the jet pump 3, and the oil, gas and water phases in the produced fluid 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. An air pipe 23 is connected to the top wall of the housing 51, and the other end of the air pipe 23 extends through the top wall of the separation tank 4 to the outside of the separation tank 4. The gas pipe 23 is provided with a gas flow meter 24, the other end is connected to a sampling unit 25, and the sampling unit 25 includes a sampling bag 251 connected to the gas pipe 23 and a hydrogen sulfide detecting element 252 located 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 meanwhile, the hydrogen sulfide detection element 252 displays and alarms in real time on line. 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 separation tank 4 is stored with recycled produced water which enters the jet pump 3 through the air flow pump 21 for recycling. The water separated by the electric flocculation device 5 enters an electric heater 12 for heating and then enters a flash tank 10 for complete oil-water separation, the produced water enters a condenser 14 for condensation and then is measured, and a small amount of crude oil is discharged from the flash tank 10 and enters a second oil storage tank.
The working principle of the oil well output liquid multi-parameter mobile measuring device of the embodiment of the invention is described as follows:
the oil well output liquid enters the liquid inlet pipe 1, the viscosity of the output liquid is reduced after heating, and the fluidity is enhanced. And the demulsifier added in the dosing system 18 changes the produced liquid into small liquid drops, and then 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. Wherein, the gas phase is discharged through the gas pipe 23, the flow of the gas is measured by the gas flowmeter 24, the gas is collected by the sampling bag 251 for subsequent test, and the hydrogen sulfide detection element 252 detects whether gas leakage exists or not, thereby ensuring the safety of the equipment.
The separated oil and water is then temporarily stored in the space to the left of the weir plate 54. Since water has a higher density than oil, water is in the lower layer and oil is in the upper layer. When the oil in the upper layer 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 the flow rate of the oil is measured by the oil flow meter 8. The water flows into the separation tank 4 through the draining hole 55 and flows into the water pipe 9, and is heated to 100 ℃ or higher (generally 103 ℃) by the heating action of the electric heater 12. Subsequently, the heated water enters the flash tank 10, the water is flashed, and the oil is still in a liquid droplet state due to the difference of the oil-water boiling points. The water thus becomes flash steam into the condenser 14 and the oil settles at the bottom of the flash tank 10 and is finally discharged through the second oil pipe 11 and metered (the second oil pipe 11 may also be provided with an oil flow meter for metering the discharged oil content). The flash steam entering the condenser 14 condenses and condenses again to liquid water, which is discharged through the condenser tube 15 and the flow rate of which is measured by the water flow meter 16. Therefore, the measurement of oil, gas and water three phases in the produced liquid is completed.
Therefore, the invention realizes the separation of oil, gas and water phases 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 oil and water by heating the separated water to more than 100 ℃ and then carrying out flash evaporation, thereby ensuring that the metering of oil and water is more accurate.
In addition, the detachable connection with the Christmas tree is realized through the quick connector, so that the mobile measurement of the oil well output liquid can be realized, and the convenience is better. And moreover, the content of oil, gas and water in the produced fluid can be measured simultaneously by one-time operation, and the measurement efficiency is higher.
The above description is only a few embodiments of the present invention, and those skilled in the art can make various changes or modifications to the embodiments of the present invention according to the disclosure of the application document without departing from the spirit and scope of the present invention.
