Description

Technical Field

[0001] This utility model relates to the field of oilfield technology, and in particular to an intelligent remote-controlled automatic dosing device. Background Technology

[0002] Waxing, scaling, and corrosion are common phenomena in oil wells. Waxing and scaling can increase the load on pumping units, or even reduce flow channels or cause pump jamming. The presence of corrosive media such as water, H2S, and CO2 in crude oil in oil wells can easily cause rod string corrosion. At present, chemical wax removal and prevention technology is widely used in oil fields. Usually, the agent is added from the annular space without affecting the normal production and other operations of the oil well. In addition to the wax removal and prevention effect, the use of certain agents can also achieve the effects of pour point reduction, viscosity reduction, and unclogging.

[0003] Currently, for chemical dosing operations in oil wells, simple wellhead dosing devices are mainly used. These devices consist of a storage tank and inlet / outlet valves, and dosing is achieved by opening and closing the gate valves. This requires manual control, which results in high labor and vehicle costs. There are also dosing devices based on remote communication control, but during long-term dosing operations, the pipelines transporting the chemicals are prone to blockage. When a blockage occurs during remote-controlled dosing operations, it is necessary to wait for maintenance personnel to arrive by vehicle for inspection and maintenance, which can easily lead to untimely dosing.

[0004] Therefore, to address the above issues, an intelligent remote-controlled automatic dosing device can be designed. By providing redundant dosing pipelines for the metering pump, remote operation switching can be performed, ensuring that if the normal dosing pipeline becomes blocked unexpectedly, the backup dosing pipeline can take over in time to complete the dosing operation, thus ensuring timely dosing. Utility Model Content

[0005] To overcome the problem that current remote-controlled dosing devices are prone to blockages in the pipelines transporting chemicals during long-term dosing operations, and that when an accidental blockage occurs during remote-controlled dosing operations, maintenance personnel must be waited for to arrive, which can easily lead to untimely dosing.

[0006] The technical solution of this utility model is as follows: an intelligent remote control automatic dosing device, including a storage tank and an output pipe installed at the outlet end of the storage tank, and a backup pipe installed at the other outlet end of the storage tank. Both the output pipe and the backup pipe are equipped with remotely controllable control valves, which are respectively connected to the two inlet ends of a three-way connector. The control valves adopt an interlock control method. When one set of control valves is in the open state, the other set of control valves simultaneously switches to the closed state. The outlet end of the three-way connector is sequentially equipped with a pumping component, another three-way connector, and an output component, forming a dual-channel dosing system.

[0007] Preferably, a storage tank is provided to store the chemicals to be added, a control component is provided to operate the entire device, a control valve is provided to control the backup and output pipelines, a set of T-joints connects the pumping component to the output and backup pipelines, and another set of T-joints connects the pumping component to the two output components. The pumping component provides kinetic energy for the delivery of chemicals, thereby drawing chemicals from the storage tank through the output pipelines and adding them to the oil wells through the output components. When the output pipeline is accidentally blocked, the backup pipeline can take over the output pipeline to promptly deliver chemicals from the storage tank, ensuring timely chemical addition and preventing disruption to normal oilfield production.

[0008] Preferably, the pumping assembly includes a metering pump and a safety valve arranged in series, with the metering pump and safety valve forming a through flow path with two sets of three-way connectors.

[0009] Preferably, the output component includes two sets of parallel check valves and auxiliary pipelines. The input end of each check valve is connected to a downstream tee pipe, and the output end is connected to an auxiliary pipeline, which is a high-pressure steel wire hose.

[0010] Preferably, the control components include an electrical control box, a level transmitter, and a pressure transmitter. The level transmitter is located on one side of the storage tank, the pressure transmitter is located at the output end of the metering pump, and the electrical control box is fixedly installed on one side of the storage tank. The electrical control box integrates a remote controller.

[0011] Preferably, the medicine storage tank has a square structure, and the inner wall of the medicine storage tank is coated with an epoxy resin coating.

[0012] Preferably, the medicine storage tank is equipped with a filling port, and a protective cap is snapped onto the upper end of the filling port.

[0013] Preferably, a motor is fixedly installed at the upper end of the medicine storage tank, and a stirring shaft is rotatably connected inside the medicine storage tank. The stirring shaft is fixedly connected to the output end of the motor.

[0014] The beneficial effects of this utility model are:

[0015] The entire unit is controlled via an electrical control box, which integrates a remote controller that can communicate with a cloud control platform via a 4G network. This eliminates the need for on-site visits for chemical dosing and equipment inspections, significantly reducing labor and vehicle costs. A backup pipeline is also provided. If the output pipeline becomes blocked, operators can remotely control the backup pipeline to open and close it via a control valve, allowing for switching between the output and backup pipelines connected to the metering pump. The backup pipeline can promptly take over from the output pipeline to deliver chemicals from the storage tank, ensuring timely dosing and preventing disruption to normal oilfield production.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment: an intelligent remote-controlled automatic dosing device, including a storage tank 1 and an output pipe 2 installed at the outlet end of the storage tank 1, and a backup pipe 3 installed at the other outlet end of the storage tank 1. Both the output pipe 2 and the backup pipe 3 are equipped with remotely controllable control valves 4, which are respectively connected to the two inlet ends of a three-way connector 5. The control valves 4 adopt an interlock control method; when one set of control valves 4 is in the open state, the other set of control valves 4 simultaneously switches to the closed state. The outlet end of the three-way connector 5 is sequentially equipped with a pumping component, another three-way connector 5, and an output component, forming a dual-channel dosing system. By setting up the storage tank 1, the required dosing agent can be dispensed... The system is designed for storage and operation. A control component allows for the overall control of the device. A control valve 4 controls the backup pipeline 3 and the output pipeline 2. A set of three-way connectors 5 connects the pumping component to the output pipeline 2 and the backup pipeline 3. Another set of three-way connectors 5 connects the pumping component to both output components. The pumping component provides kinetic energy for the delivery of chemicals, allowing chemicals to be drawn from the storage tank 1 through the output pipeline 2 and added to the oil well through the output component. If the output pipeline 2 becomes blocked, the backup pipeline 3 can promptly take over, ensuring timely chemical delivery and preventing disruption to normal oilfield production.

[0023] Please see Figure 1 and Figure 2In this embodiment, the pumping component includes a metering pump 801 and a safety valve 802 connected in series. The metering pump 801 and the safety valve 802 form a through flow path with two sets of three-way connectors 5. By setting the metering pump 801, the agent can be precisely and quantitatively pumped from the storage tank 1. By setting the safety valve 802, the metering pump 801 can be prevented from being damaged by equipment pressure due to misoperation. The output component includes two sets of parallel check valves 6 and auxiliary pipelines 7. The input end of each check valve 6 is connected to the downstream three-way connector 5, and the output end is connected to the auxiliary pipeline 7. The auxiliary pipeline 7 adopts a high-pressure steel wire hose. By setting the auxiliary pipeline 7, the agent can be output to the oil well. The auxiliary pipeline 7 adopts a high-pressure steel wire hose for easy adjustment. By setting the check valves 6, the gas and liquid in the oil well can be prevented from entering the well. Overflow and backflow can affect the overall device. The control components include an electrical control box 901, a level transmitter 902, and a pressure transmitter 903. The level transmitter 902 is located on one side of the storage tank 1, and the pressure transmitter 903 is located at the output end of the metering pump 801. The electrical control box 901 is fixedly installed on one side of the storage tank 1, and a remote controller is integrated inside the electrical control box 901. The entire device can be controlled by the electrical control box 901. The remote controller integrated inside the electrical control box 901 can communicate with the cloud control platform through a 4G network to achieve remote control. The level transmitter 902 can monitor the amount of medicine in the storage tank 1 in a timely manner, and the output pressure of the metering pump 801 can be monitored to ensure that the metering pump 801 can operate normally.

[0024] Please see Figure 3 and Figure 4 In this embodiment, the medicine storage tank 1 has a square structure, and the inner wall of the medicine storage tank 1 is coated with epoxy resin. The square structure of the medicine storage tank 1 is convenient for welding and easy to maintain. The epoxy resin coating inside can prevent the medicine from corroding the medicine storage tank 1 from the inside. The medicine storage tank 1 is provided with a filling port 101, and a protective cover 102 is snapped onto the upper end of the filling port 101. The medicine can be added into the medicine storage tank 1 through the filling port 101, and the protective cover 102 can cover and protect the filling port 101 when no medicine is being added. A motor 103 is fixedly installed at the upper end of the medicine storage tank 1, and a stirring shaft 104 is rotatably connected inside the medicine storage tank 1. The stirring shaft 104 is fixedly connected to the output end of the motor 103. By setting the motor 103 to drive the stirring shaft 104 to rotate, the medicine in the medicine storage tank 1 can be stirred to ensure that the medicine is mixed evenly.

[0025] During operation, the entire device is controlled using an electrical control cabinet. The cabinet integrates a remote controller that can communicate with the cloud control platform via a 4G network. The main functions of the remote controller are analog signal acquisition, relay output, and wireless data transmission. The analog signal acquisition is connected to the lower-level machine through the I / O interface, and the source 4-20mA variable is converted into digital data through A / D conversion. The relay output port can control the start and stop of the pump by controlling the AC contactor. The wireless data part packages the converted data into TCP or UDP packets and sends them to the remote central server, thereby realizing remote monitoring and control of the cloud platform.

[0026] During normal dosing operations, the internal control valve 4 of the backup pipeline 3 is closed, and one set of check valves 6 is closed. The metering pump 801 accurately and quantitatively draws the agent from the storage tank 1 through the output pipeline 2, and then adds the agent to the oil well through the auxiliary pipeline 7. The safety valve 802 can prevent the equipment from being pressurized and damaged by misoperation. The liquid level transmitter 902 can monitor the agent level in the storage tank 1 in a timely manner. By setting the output pressure of the metering pump 801 for monitoring, it is ensured that the metering pump 801 can operate normally.

[0027] If the output pipeline 2 becomes blocked, the backup pipeline 3 is opened by the control valve 4 and the output pipeline 2 is closed. The backup pipeline 3 can take over from the output pipeline 2 to output the agent in the storage tank 1 in a timely manner, ensuring the timeliness of the agent addition and preventing the impact on the normal production of the oil field. When the auxiliary pipeline 7 becomes blocked, the other set of auxiliary pipelines 7 is switched to transport the agent to ensure that the agent can be injected into the oil well normally.

[0028] Through the above steps, the pumping component provides kinetic energy for the delivery of the chemical agent, thereby drawing the chemical agent from the storage tank 1 through the output pipe 2 and adding it to the oil well through the output component. When the output pipe 2 is accidentally blocked, a backup pipe 3 can be set up to take over the output of the chemical agent from the storage tank 1 in a timely manner, ensuring the timeliness of chemical dosing and preventing the impact on normal oilfield production. This solves the problem that in current remote communication controlled chemical dosing devices, the pipelines delivering the chemical agent are prone to blockage during long-term chemical dosing operations. When an accidental blockage occurs during remote control chemical dosing operations, it is necessary to wait for maintenance personnel to drive over for inspection and maintenance, which can easily lead to untimely chemical dosing.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
