Description

Technical Field

[0001] This utility model relates to a multi-mode liquid level sensing oil well multi-storage device, belonging to the field of oil extraction equipment technology. Background Technology

[0002] In the field of oilfield development, remote oil wells lack supporting pipelines for transporting produced fluids. They need to use multiphase storage devices to separate, store, and heat the mixed produced fluids of crude oil, water, and gas. The produced fluids are then transported by tanker trucks. The separated gas can be used as fuel to provide energy for heating the device.

[0003] Existing multiphase storage devices for oil wells mainly consist of a horizontal container, burner, fire tube, chimney, and pointer level indicator system. After the produced fluid enters the horizontal container, it undergoes storage and gas-liquid separation. The burner combusts the separated gas to heat the fire tube, thereby increasing the temperature of the produced fluid and reducing its viscosity. However, this device has the following technical defects in practical use:

[0004] 1. Poor environmental performance: The burner directly uses untreated separated gas as fuel, and the smoke and dust produced after combustion contains excessive levels of harmful gases such as nitrogen oxides, which cannot meet the current environmental emission standards.

[0005] 2. Low reliability of liquid level measurement: Existing multiphase storage devices for oil wells use mechanical pointer liquid level indication systems for liquid level measurement. This method has a high failure rate and is prone to liquid level detection distortion, which can lead to excessively high liquid levels and cause produced fluid overflow, resulting in pollution of the surrounding ecological environment.

[0006] 3. Low monitoring efficiency: The equipment is mostly used in remote oil wells with inconvenient transportation and communication, relying on manual on-site monitoring and operation, which not only has high labor costs, but is also prone to equipment failure and safety accidents due to human error. Utility Model Content

[0007] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an oil well multi-mode liquid level sensing device that solves the problems of environmentally unfriendly combustion, high failure rate of liquid level measurement, and low efficiency of manual monitoring in existing devices.

[0008] The oil well multi-storage device integrating multi-mode liquid level sensing described in this utility model includes a base, on which an oil collector is installed. The oil collector is connected to an oil inlet pipeline, an oil outlet pipeline, and an exhaust pipeline. The oil collector is equipped with a magnetic float level gauge, a differential pressure level gauge, and an inclination level gauge. It measures the liquid level through multiple modes, eliminating the risk of overflow caused by liquid level measurement failure and avoiding environmental accidents.

[0009] The oil collector is also equipped with an electric heater mounting flange. The electric heater is fixedly connected to the oil collector through the electric heater mounting flange, and the heating end of the electric heater extends into the oil collector. The electric heater is used to heat the liquid inside the oil collector, replacing the burner to achieve combustion-free heating and eliminating the environmental problems caused by gas combustion.

[0010] Preferably, the oil collector is equipped with a cyclone separator and a wire mesh demister inside. The cyclone separator is connected to the outlet end of the oil inlet pipeline to achieve efficient gas-liquid separation of the produced fluid. The wire mesh demister is located in the gas phase zone of the oil collector and is connected to the inlet end of the exhaust pipeline to remove small droplets from the gas.

[0011] Furthermore, the oil collector is also equipped with a temperature transmitter and a pressure transmitter, both of which have their detection ends extending into the oil collector to enable real-time monitoring of the temperature and pressure of the extracted liquid inside the device.

[0012] Preferably, a combustible gas detector and a hydrogen sulfide gas detector are also fixedly installed on the base to realize real-time monitoring of toxic and explosive gas leaks.

[0013] Preferably, the tilt level gauge is equipped with a float ball, which is installed inside the oil collector. The tilt level gauge obtains the liquid level height data by detecting the angle change of the float ball. The magnetic level gauge detects the liquid level based on the principle of buoyancy and magnetic coupling, and the differential pressure level gauge detects the liquid level based on the change of static pressure. The three form a multi-dimensional liquid level detection system.

[0014] Furthermore, the bottom of the oil collector is also connected to a drain line; before transferring the oil collector, the liquid inside the oil collector is drained through the drain line.

[0015] Furthermore, control valves are installed on the drain line, oil inlet line, and oil outlet line.

[0016] Furthermore, this device is also equipped with a data acquisition box, which is electrically connected to the magnetic float level gauge, differential pressure level gauge, tilt level gauge, electric heater, temperature transmitter, pressure transmitter, combustible gas alarm, and hydrogen sulfide gas alarm. The data acquisition box integrates a data processing unit, a power supply unit, and a remote communication module, which can transmit various detection data and fault signals to the monitoring room in real time to realize remote monitoring and early warning.

[0017] The advantages of this utility model compared with the prior art are:

[0018] 1. This utility model constructs a multi-mode liquid level detection system by using a magnetic float level gauge, a differential pressure level gauge, and an incline level gauge. The liquid level height is detected based on three different principles: buoyancy, static pressure, and float angle. The failure of any detection component will not affect the overall liquid level monitoring, thus completely solving the problem of high failure rate of mechanical pointer level gauges. It effectively prevents the overflow of produced liquid caused by liquid level detection distortion and avoids pollution of the surrounding environment.

[0019] 2. This utility model heats the liquid inside the oil collector with an electric heater, which can achieve combustion-free heating and eliminate the environmental problems caused by gas combustion.

[0020] 3. The oil collector is equipped with a cyclone separator and a wire mesh demister, and introduces centrifugal separation technology to separate the gas into gas and liquid, which improves the processing efficiency.

[0021] 4. This utility model integrates all detection data from multi-mode liquid level detectors, temperature and pressure transmitters, combustible and hydrogen sulfide gas alarms through a data acquisition box, and transmits the data to the remote monitoring room in real time. It has a fault early warning function and can send early warning signals in a timely manner when the detection data exceeds the standard or the device malfunctions. No manual on-site monitoring is required, which greatly improves monitoring efficiency, reduces the risk of human error, and is suitable for the operating environment of remote oil wells.

[0022] 5. This utility model integrates components such as oil collector, data acquisition box, various alarms, level gauge and heater on the base to form an integrated skid-mounted device. The overall structure is compact and does not require complicated on-site assembly. It can be directly transported to remote oil well operation sites by vehicle, which greatly reduces transportation and installation costs. Attached Figure Description

[0027] The present invention will be further described below with reference to specific embodiments.

[0028] like Figure 1-3 As shown, this embodiment is achieved through the following technical solution: It includes a base 4, on which an oil collector 1 is mounted. The oil collector 1 is connected to an oil inlet pipe 3, an oil outlet pipe 8, and an exhaust pipe 2. The oil collector 1 is equipped with a magnetic level gauge 6, a differential pressure level gauge 7, and an inclination level gauge 12. Multiple modes are used to measure the liquid level, eliminating the risk of overflow due to level measurement malfunctions and preventing environmental accidents. The oil collector 1 is also equipped with an electric heater mounting flange 101, which is fixedly connected to the oil collector 1. The heating end of the electric heater extends into the interior of the oil collector 1. The electric heater is used to heat the liquid inside the oil collector 1, replacing the burner to achieve combustion-free heating and eliminating environmental problems caused by gas combustion.

[0029] In this embodiment, the oil collector 1 is equipped with a cyclone separator 103 and a wire mesh demister 102. The cyclone separator 103 is connected to the outlet end of the oil inlet pipeline 3 to achieve efficient gas-liquid separation of the produced fluid. The wire mesh demister 102 is located in the gas phase zone of the oil collector 1 and is connected to the inlet end of the exhaust pipeline 2 to remove small droplets from the gas. The exhaust pipeline 2 is equipped with a self-regulating valve, which can keep the pressure of the oil collector 1 constant and automatically discharge excess gas.

[0030] The oil collector 1 is also equipped with a temperature transmitter 9 and a pressure transmitter 5, both of which have their detection ends extending into the oil collector 1 to achieve real-time monitoring of the temperature and pressure of the extracted liquid inside the device. The base 4 is also fixedly equipped with a combustible gas alarm 10 and a hydrogen sulfide gas alarm 11 to achieve real-time monitoring of leaks of toxic and explosive gases.

[0031] The tilt level gauge 12 is equipped with a float 104, which is installed inside the oil collector 1. The tilt level gauge 12 obtains liquid level data by detecting the angle change of the float 104. The magnetic level gauge 6 detects the liquid level based on the principle of buoyancy and magnetic coupling. The differential pressure level gauge 7 detects the liquid level based on the change of static pressure. The three form a multi-dimensional liquid level detection system.

[0032] The bottom of the oil collector 1 is also connected to a drain line 13; before transferring the oil collector 1, the liquid inside the oil collector 1 is drained through the drain line 13. Control valves are installed on the drain line 13, the oil inlet line 3, and the oil outlet line 8.

[0033] This device is also equipped with a data acquisition box, model FBK-53-125. The data acquisition box is electrically connected to the magnetic float level gauge 6, differential pressure level gauge 7, tilt level gauge 12, electric heater, temperature transmitter 9, pressure transmitter 5, combustible gas alarm 10, and hydrogen sulfide gas alarm 11. The data acquisition box integrates a data processing unit, a power supply unit, and a remote communication module, which can transmit various detection data and fault signals to the monitoring room in real time to realize remote monitoring and early warning.

[0034] The working process of this utility model is as follows:

[0035] The produced fluid from the oil well enters the oil collector 1 through the inlet pipeline 3. Inside the oil collector 1, gas-liquid separation is performed in the cyclone separator 103. The separated liquid flows to the lower part of the oil collector 1, while the separated gas rises into the gas phase zone of the oil collector 1. Small droplets in the gas are removed by the wire mesh demister 102 and discharged through the exhaust pipeline 2. At the same time, due to the pressure inside the oil collector 1, the liquid separated by the cyclone separator 103 is automatically discharged through the outlet pipeline 8.

[0036] Throughout the process, the electric heater installed on the electric heater mounting flange 101 heats the liquid inside the oil collector 1 to reduce its viscosity; when the device needs to be transported, the liquid inside the oil collector 1 is drained through the drain line 13 to facilitate transportation.

[0037] This device is equipped with an incline level gauge 12, a magnetic float level gauge 6, and a differential pressure level gauge 7, which together form a multi-dimensional level detection system to detect the liquid level. It is also equipped with a temperature transmitter 9, a combustible gas alarm 10, a hydrogen sulfide gas alarm 11, and a pressure transmitter 5, which can detect the temperature and pressure of the device, as well as whether there is any overflow of combustible gas or hydrogen sulfide gas. The relevant measured data can be transmitted to the monitoring room through the data acquisition box to realize remote monitoring and early warning.
