Description

[0002] Crude oil extracted from oil wells contains oil, gas, water, and small amounts of mud and other substances. Most existing oil wells use a method of separating oil, gas, and water at various levels of transportation stations and then transporting them separately, or using a gas-liquid mixing transportation device for gas-liquid mixing transportation.

[0003] In the field of oil and gas transportation, the accurate transport and metering of gas-liquid mixtures is crucial. However, how to simultaneously achieve precise measurement of oil and gas during transportation has been a persistent challenge for existing technologies.

[0047] Figure 1 This diagram illustrates a gas-liquid metering and mixing conveying system according to an embodiment of the present invention. Figure 1 As shown, the gas-liquid metering and mixing conveying system includes:

[0048] First container 101;

[0049] Second container 102;

[0050] The medium inlet pipe 103 is connected to the first container 101 and the second container 102 respectively, and is used to input the oil-gas mixture into the first container 101 and the second container 102;

[0051] The medium outlet pipe 103 is connected to the first container 101 and the second container 102 respectively, and is used to output the oil-gas mixture from the first container 101 and the second container 102.

[0052] The first solenoid valve 107 and the third solenoid valve 109 are connected to the medium inlet pipe 103.

[0053] The second solenoid valve 108 and the fourth solenoid valve 110 are connected to the medium outlet 104.

[0054] The oil-gas separator 113 is connected to the medium outlet pipe 104 and is used to separate the oil-gas mixture into liquid and gas.

[0055] A first gas metering sensor 114 and a first liquid metering sensor 115 are respectively installed at the output end of the oil-gas separator 113. The first gas metering sensor 114 is used to measure the volume of the output gas, and the first liquid metering sensor 115 is used to measure the volume of the output liquid.

[0056] The first power mechanism 105 is connected to the first container 101;

[0057] The second power mechanism 106 is connected to the second container 102;

[0058] The first container 101, the first power mechanism 105, the second power mechanism 106, and the second container 102 are connected by pipelines;

[0059] The first container 101 and / or the second container 102 also contain a kinetic fluid;

[0060] The first power mechanism 105 is used to transport the power fluid in the first container 101 to the second container 102 through a pipeline; the second power mechanism 106 is used to transport the power fluid in the second container 102 to the first container 101 through a pipeline;

[0061] The control unit (not shown in the figure) is connected to and controls the operation of the first power mechanism 105, the second power mechanism 106, the first solenoid valve 107, the second solenoid valve 108, the third solenoid valve 109, the fourth solenoid valve 110, the oil-gas separator 113, the first gas metering sensor 114, and the first liquid metering sensor 115.

[0062] This invention provides a gas-liquid metering and mixing conveying system. By configuring gas flow meters and liquid flow meters, it can accurately measure the volume of the gas-liquid mixture, ensuring metering accuracy during the conveying process and avoiding the errors of traditional post-separation metering. The system simplifies equipment complexity, reduces the use of mechanical equipment, and lowers failure rates and maintenance costs through the cooperation of solenoid valves, power mechanisms, and control units. The oil-gas separator effectively separates the oil-gas mixture into gas and liquid, ensuring that the flow rate of each substance can be independently measured, providing accurate data for subsequent processing. By optimizing the coordinated operation of the pump and solenoid valves, the system can reduce energy consumption and environmental impact while maintaining conveying efficiency. This invention enables gas-liquid mixing and conveying with low cost, high efficiency, and long service life.

[0063] In one embodiment, a first solenoid valve 107 and a second solenoid valve 108 are disposed in the pipeline connecting to the first container 101. The first solenoid valve 107 controls the input of the oil-gas mixture into the first container 101, and the second solenoid valve 108 controls the output of the oil-gas mixture into the first container 101. In this embodiment, the control unit (not shown in the figure) precisely controls the input and output of the oil-gas mixture by disposing of the first solenoid valve 107 and the second solenoid valve 108 in the pipeline connecting to the first container 101. The first solenoid valve 107 is located at the inlet end of the pipeline and controls the input of the oil-gas mixture. When injection is required, the control unit sends a signal to drive it to open; when the input stops, the valve closes. The second solenoid valve 108 is disposed at the outlet end and controls the output of the oil-gas mixture. The control unit drives it to open or close as needed. This system, through intelligent solenoid valve control, adjusts the input and output in real time to ensure that the oil-gas mixture in the container is always maintained at a predetermined level, thereby improving the operating efficiency of the system.

[0064] In one embodiment, a third solenoid valve 109 and a fourth solenoid valve 110 are disposed in the pipeline connecting to the second container 102. The third solenoid valve 109 is used to control the input of the oil-gas mixture in the second container 102, and the fourth solenoid valve 110 is used to control the output of the oil-gas mixture in the second container 102. In this embodiment, the system achieves precise control of the oil-gas mixture in the second container 102 by distributing the third solenoid valve 109 and the fourth solenoid valve 110 in the pipeline connecting to the second container 102. The third solenoid valve 109 is located at the inlet end of the pipeline and is mainly used to control the input of the oil-gas mixture. The control unit (not shown in the figure) sends a signal according to system requirements to drive the third solenoid valve 109 to open or close, so as to precisely adjust the input amount. When the input is complete or no more oil-gas mixture is needed, the valve closes. The fourth solenoid valve 110 is disposed at the outlet end and controls the output of the oil-gas mixture. The control unit ensures that the output of the oil-gas mixture meets the predetermined requirements by adjusting the opening and closing of the fourth solenoid valve 110. Through this precise solenoid valve control, the system can dynamically adjust the flow of the oil-gas mixture in the second container 102, optimize the system's working efficiency, ensure that the material in the container is kept at an appropriate level, and avoid unstable operation caused by excessive input or uneven output.

[0065] Figure 2 This diagram illustrates a gas-liquid metering and mixing conveying system according to another embodiment of the present invention. Figure 2 As shown, the driving fluid in the gas-liquid metering and mixing conveying system is water; the oil-gas separator 113 includes an oil-gas-water three-phase separator for separating oil, gas, and water output from the medium outlet pipe; the first gas metering sensor 114 is used to measure the volume of the output gas; the first liquid metering sensor 115 is used to measure the volume of the output oil; the oil-gas-water three-phase separator also includes a second liquid metering sensor 119 for measuring the volume of water discharged from the medium outlet pipe. In this embodiment, the driving fluid of the gas-liquid metering and mixing conveying system is water, and the stability and reliability of the system operation are ensured through precise flow control and monitoring. The oil-gas separator 113 in the system adopts an oil-gas-water three-phase separator, which can effectively separate oil, gas, and water output from the medium outlet pipe. The first gas metering sensor 114 is used to measure the volume of the output gas in real time, while the first liquid metering sensor 115 is used to accurately measure the volume of the output oil. In addition, the oil-gas-water three-phase separator is also equipped with a second liquid metering sensor 119 for monitoring and measuring the volume of water discharged from the medium outlet pipe. Through the precise coordination of these sensors, the system can efficiently and accurately separate three-phase media and accurately measure the volume of each medium, thereby ensuring the flow control of the gas-liquid mixture and the high efficiency of system operation.

[0066] In one embodiment, such as Figure 2As shown, the gas-liquid metering and mixing conveying system includes: a first motive fluid level sensor 116, connected to the first container 101, for detecting whether there is motive fluid in the first container 101 and for measuring the level of the motive fluid in the first container 101; and a second motive fluid level sensor 117, connected to the second container 102, for detecting whether there is motive fluid in the second container 102 and for measuring the level of the motive fluid in the second container 102. Figure 2 As shown, the system is equipped with a first power fluid level sensor 116 and a second power fluid level sensor 117 to ensure the normal supply and monitoring of power fluid within the system. The first power fluid level sensor 116 is connected to the first container 101 and is responsible for detecting whether there is power fluid in the first container 101 and measuring the power fluid level in the container in real time to prevent the normal operation of the system from being affected by excessively low or high levels. Similarly, the second power fluid level sensor 117 is connected to the second container 102 and is responsible for detecting the state of the power fluid in the second container 102 and measuring changes in level to ensure that the power fluid in the second container is always within a suitable level range. Through the combined use of these two level sensors, the system can monitor the status of the power fluid in real time, ensuring that the level in each container remains within a safe operating range, thereby improving the operational stability and reliability of the gas-liquid mixing and conveying system.

[0067] In one embodiment, the control unit (not shown) is further configured to activate the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110, and close the second power mechanism 106, the second solenoid valve 108, and the third solenoid valve 109 if the power fluid in the first container 101 is detected to be higher than a first set value.

[0068] In one embodiment, the control unit (not shown) is also configured to shut down the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110, and start the second power mechanism 106, the second solenoid valve 108, and the third solenoid valve 109 if the power fluid in the first container 101 is detected to be lower than a second set value.

[0069] The control unit (not shown in the figure) has intelligent monitoring and regulation functions to ensure the stable operation of the gas-liquid metering and mixing conveying system. When the power fluid level in the first container 101 is detected to be higher than the first set value (e.g., 70% of the total liquid level), the control unit will activate the first power mechanism 105 and open the first solenoid valve 107 and the fourth solenoid valve 110 to ensure that the power fluid can be conveyed through the set path. At the same time, to avoid system overload operation, the control unit will close the second power mechanism 106, the second solenoid valve 108, and the third solenoid valve 109 to reduce unnecessary flow and prevent the container liquid level from being too high. Conversely, when the power fluid level in the first container 101 is detected to be lower than the second set value (e.g., 10% of the total liquid level), the control unit will automatically adjust the system state. At this time, the control unit will close the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110 to prevent excessive input. Simultaneously, the control unit activates the second power mechanism 106, opening the second solenoid valve 108 and the third solenoid valve 109 to guide more power fluid into the first container 101, thereby maintaining the normal operation of the system and ensuring the liquid level remains within a safe range. Through this dynamic adjustment, the system can achieve automated management, optimize resource utilization, and ensure the efficiency and safety of the conveying process.

[0070] In one embodiment, the control unit (not shown in the figure) is also used to shut down the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110, and start the second power mechanism 106, the second solenoid valve 108, and the third solenoid valve 109 if the power fluid in the second container 102 is detected to be higher than a third set value.

[0071] In one embodiment, the control unit (not shown) is also configured to activate the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110, and close the second power mechanism 106, the second solenoid valve 108, and the third solenoid valve 109 if the power fluid in the second container 102 is detected to be lower than a fourth set value.

[0072] The control unit (not shown in the figure) monitors the power fluid level in the second container 102 in real time and automatically adjusts it according to the set level threshold. When the power fluid level in the second container 102 is detected to be higher than a third set value (e.g., 70% of the total liquid level), the control unit automatically shuts off the first power mechanism 105, the first solenoid valve 107, and the fourth solenoid valve 110, stopping the input of power fluid into the first container 101. At the same time, the control unit activates the second power mechanism 106 and opens the second solenoid valve 108 and the third solenoid valve 109 to guide the power fluid into the second container 102, ensuring that the power fluid in the second container is maintained at a suitable level, thereby preventing the liquid level in the second container from being too high and affecting the stability of the system. Conversely, when the power fluid level in the second container 102 is detected to be lower than a fourth set value (e.g., 70% of the total liquid level), the control unit activates the first power mechanism 105 and opens the first solenoid valve 107 and the fourth solenoid valve 110 to inject more power fluid into the first container 101, keeping the liquid level within a safe range. At the same time, the control unit will shut down the second power mechanism 106, the second solenoid valve 108 and the third solenoid valve 109, and stop the delivery of power fluid in the second container 102 to avoid system instability or failure to operate normally due to low liquid level.

[0073] Through this intelligent liquid level regulation mechanism, the control unit can automatically adjust the working status of the first and second power mechanisms, as well as the switching of related solenoid valves, according to the changes in the liquid level in the second container 102. This ensures that the system can operate in the best working condition, avoids the adverse effects of excessively high or low liquid levels on the system, and improves the system's safety, stability, and automation level.

[0074] In one embodiment, the first power fluid level sensor 116 and / or the second power fluid level sensor 117 are provided with a heat insulation structure. According to the concept of this utility model, the provision of the heat insulation structure is not limited.

[0075] In one embodiment, the insulation structure is an insulation material layer covering the outer periphery of the first power fluid level sensor 116 and the second power fluid level sensor 117. Providing an insulation material layer can prevent crude oil from entering the level gauge and solidifying due to ambient temperature, thus preventing the level gauge from accurately reflecting the level of the power medium in the first container 101 and the second container 102.

[0076] In one embodiment, a third liquid metering sensor 118 is installed on the pipeline connecting the first power mechanism 105 and the second power mechanism 106 to detect the flow direction and flow rate of the power fluid in the pipeline connecting the first power mechanism 105 and the second power mechanism 106.

[0077] Specifically, a third liquid metering sensor 118 is installed on the pipeline connecting the two power mechanisms. This sensor can monitor the flow direction and flow rate of the liquid in the pipeline in real time and feed the data back to the control unit (not shown in the figure). The control unit receives the detection data from the third liquid metering sensor 118 and judges the liquid delivery status in the pipeline based on a set flow rate threshold. When it is detected that the liquid flow rate from the first container 101 to the second container 102 via the first power mechanism 105 exceeds the preset flow rate threshold, the control unit can switch to shutting off the first power mechanism 105 and activating the pipeline channel of the second power mechanism 106 to change the liquid flow direction, so that the second power mechanism 106 draws the power fluid from the second container 102 and transfers it to the first container 101. Similarly, if it is detected that the liquid flow rate from the second container 102 to the second container 101 via the first power mechanism 106 exceeds the preset flow rate threshold, the control unit can switch to shutting off the second power mechanism 106 and activating the pipeline channel of the first power mechanism 105 to change the liquid flow direction. The control unit (not shown in the figure) monitors the flow rate or velocity of the power fluid in the pipeline connecting the first container 101 and the second container 102 via a third liquid metering sensor 118. It can adjust the operating status of the first power mechanism 105 or the second power mechanism 106, such as reducing its operating power or suspending operation, to reduce the liquid flow rate in the pipeline and ensure delivery stability. When an abnormal increase in flow rate may lead to excessive pipeline load or unstable delivery pressure, the control unit can trigger an emergency response mechanism, such as temporarily stopping pipeline operation to prevent system overload.

[0078] In one embodiment, the control unit (not shown in the figure) includes a timer for precisely controlling the operating time of the first and second power mechanisms. This timer allows the control unit to control the start and stop operations of the first and second power mechanisms in a time-triggered mode according to a preset trigger time. This time-controlled method can precisely manage the delivery process of the power fluid according to different operational requirements, ensuring the efficient operation of the system.

[0079] Specifically, the control unit sets a trigger time, which is typically set to be less than the time required for the power medium to completely flow out of the first container 101 or the second container 102. For example, if it takes 3 minutes for the power medium to completely flow out of the first container 101 or the second container 102, the control unit can set the trigger time to between 165 and 170 seconds. Within this time period, the control unit determines whether to start or stop the corresponding power mechanism based on information such as liquid level and flow rate, ensuring that the power fluid in the container flows out within the specified time and avoiding over-transmission.

[0080] This time-based control mode allows the system to precisely regulate the liquid flow time, avoiding excessive or insufficient liquid delivery, thereby optimizing delivery efficiency and improving the overall system stability. Furthermore, the introduction of this timer significantly enhances the system's automation level, reducing the need for manual intervention and enabling the system to operate efficiently and stably without human intervention.

[0081] According to one embodiment of this utility model, a first pressure sensor 111 is installed on the first container 101, and a second pressure sensor 112 is installed on the second container 102. The pressure sensors can monitor the pressure changes inside the first container 101 and the second container 102 to ensure that the system is within a safe range. When an abnormal pressure (too high) is detected, an alarm system can be triggered to remind the operator to take appropriate measures. The first container 101 and the second container 102 are respectively connected to drain pipes (not shown in the figure) to periodically discharge impurities or sediments in the pressure tanks during system operation, ensuring long-term stable operation of the equipment. To ensure the safety and efficiency of the draining process, one-way drain valves are respectively installed at the connection points of the first container 101 and the second container 102 with the drain pipes. The function of the one-way drain valve is to only allow liquid or gas in the drain pipe to flow to the external discharge system, preventing liquid or gas from flowing back into the pressure tank, thereby avoiding unnecessary pollution or pressure fluctuations in the system. This design improves the automation level and ease of operation of the system, making equipment maintenance and cleaning simpler and safer, effectively extending the service life of the equipment and ensuring the stable operation of the entire gas-liquid metering and mixing conveying system.
