Description

Technical Field

[0001] The utility model relates to the field of measurement technology, in particular to a multi-well electric choke manifold wireless networking monitoring system. Background Art

[0002] During the oil and gas extraction process, the high-pressure fluid at the wellhead needs to be pressure controlled. The wellhead surface process requires the use of a throttle manifold for effective throttling and pressure control operations. The throttle manifold is generally equipped with gate valves and throttle valves for operation and control, as well as pressure, flow, and temperature instruments or sensors. During the operation, it is necessary to accurately monitor the pressure, flow, and temperature data in real time around the clock to ensure the well control pressure balance and the smooth progress of production operations.

[0003] In the past, choke manifold valves were mostly hydraulically controlled, and on-site manifold fluid data such as pressure, flow, and temperature were primarily monitored by field instruments. This required on-site operator inspections, which was time-consuming and labor-intensive, resulting in inaccurate recording, errors, and incomplete storage. An alternative approach, using a single-well choke manifold control cabinet for monitoring and display, allows for real-time monitoring with minimal errors. However, this also requires operators to regularly visit the wellsite to inspect the control cabinet's monitoring data and report the recorded data back to the wellsite's central control station. Choke manifolds are typically used by multiple wells in a single oil and gas production area. Flow, pressure, and temperature data must be accurately monitored and recorded in real time, with additional functionality such as regular storage, abnormality alarms, and data upload and sharing with a higher-level management center. With existing technology and equipment, wellsite operators face a heavy workload, low efficiency, inaccurate data recording, missed inspections, and inadequately scheduled inspections. Furthermore, in the event of an emergency, the central control station cannot simultaneously monitor the operational data of multiple choke manifolds in real time, immediately open and close the electric choke valves, and record and share the data. Another aspect of the problem is that if multiple throttling manifold control cabinets are connected to the central control station with communication cables, a large number of cables will be required to cover a distance of several kilometers in multiple directions. The labor intensity of operators laying and installing cables will increase, and the outdoor site environment and working conditions are harsh, which can easily lead to control cable damage and signal interruption. If not discovered in time, it can easily lead to data loss, shutdown and production, and even safety accidents. Utility Model Content

[0027] like Figure 3As shown, the pressure transmitter includes an inlet side pressure transmitter, a first-level pressure transmitter, a second-level pressure transmitter and an outlet side pressure transmitter; the temperature transmitter includes an inlet side temperature transmitter, a first-level temperature transmitter and a second-level temperature transmitter; the flow transmitter includes an inlet side flow transmitter, a first-level flow transmitter and a second-level flow transmitter; the electric gate valve is an inlet side electric gate valve; the electric throttle valve includes an inlet side electric throttle valve, a first-level electric throttle valve, a second-level electric throttle valve and an outlet side electric throttle valve; the first-level pipeline and the second-level pipeline are connected in parallel to form a parallel pipeline, and one end of the parallel pipeline is connected to the The inlet pipeline is connected, and the other end of the parallel pipeline is connected to the outlet pipeline.

[0029] like Figure 1 As shown, the structures of the first to tenth electric throttling manifold units are the same, and the structures of the first to tenth terminal electric control cabinets are the same.

[0030] Details are as follows:

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, the controlled objects include the first terminal electric control cabinet, the second terminal electric control cabinet, the third terminal electric control cabinet to the Nth terminal electric control cabinet.

[0032] Each electric throttle manifold unit is equipped with a terminal electrical control cabinet. The central control station is equipped with a central integrated electrical control cabinet. When the entire control system is powered on and the communication and control programs programmed for the master controller are executed, the master controller of the central integrated electrical control cabinet connects to the terminal-side wireless communication units of the terminal electrical control cabinets via the master wireless communication unit to control the terminal-side controllers of the terminal electrical control cabinets, forming a stable wireless communication framework for exchanging digital signals.

[0033] The central control integrated electrical control cabinet can wirelessly control up to 10 single-well electric choke manifolds. This solution enables precise throttling control of multiple wells in a single oil and gas production area. Pressure, flow, and temperature data can be accurately monitored, recorded, regularly stored, and alarmed 24 / 7 in real time.

[0034] The central control station uses an integrated host computer and large-screen monitoring system. Running the pre-programmed host computer control program, the system connects to the main controller via open-user TCP communication to monitor all intelligent transmitter data and control all intelligent electric valves. The host computer also shares interface data with the central control screen via a TV-BOX connection. If abnormal data is detected, emergency opening and closing of electric gate valves or adjustment of the percentage opening of electric throttle valves can be implemented to meet the control requirements of the electric throttle manifold production process.

[0035] The electric throttle manifold central control integrated monitoring system can also independently control one set of electric throttle manifold units. All monitoring and control functions are the same. When monitoring and controlling multiple sets, it is only necessary to expand the central control integrated electric control cabinet and write the CPU and host computer software.

[0036] like Figure 3 and Figure 4 As shown, the electric throttling manifold unit is provided with a high-pressure fluid inlet, a first-stage throttling, a second-stage throttling and an outlet.

[0037] The wireless modules configured in the central integrated electrical control cabinet and the terminal electrical control cabinet are paired and use external antennas to amplify the signal transmission and reception power to ensure stable wireless communication.

[0038] Both the central control integrated electrical cabinet and the terminal electrical cabinet are equipped with surge protectors. They prevent damage to electrical equipment by quickly directing surge voltages or currents in the electrical system to the ground, preventing these surges from passing through the equipment and protecting it from damage. They also protect human safety by effectively reducing surge voltages in the electrical system and alleviating threats to personal safety from electric shock. They improve system stability and reliability by reducing surge voltages and currents in the electrical system, reducing the probability of system failures, extending equipment life, and ultimately improving overall system stability and reliability. They also protect data and information security by preventing surge voltages from damaging sensitive electronic equipment such as computers, servers, and communications equipment, thereby safeguarding data and information.

[0039] The terminal electrical control cabinet is equipped with explosion-proof isolation gratings for analog signal inputs. This serves to isolate the analog input and output signals of the explosion-proof electrical control cabinet from those of on-site explosion-proof electrical equipment, preventing hazardous energy from non-intrinsically safe circuits from entering intrinsically safe circuits and ensuring that the energy transmitted to on-site explosion-proof electrical equipment is intrinsically safe.

[0040] The terminal electrical control cabinet of the electric throttle manifold controls each electric gate valve and electric throttle valve through bus communication, including executing switch commands and receiving status signal feedback. The terminal electrical control cabinet controls each pressure transmitter, flow transmitter, and temperature transmitter through analog monitoring.

[0041] like Figure 2 and Figure 4 As shown, the central control integrated electric control cabinet and the terminal electric control cabinet are equipped with UPS power supply. This function is to automatically start the UPS power supply as an emergency power supply to supply power to the central control station integrated electric control cabinet, the on-site terminal electric control cabinet and the intelligent transmitter in the event of a sudden power outage at the central control station and the on-site AC220V power supply, ensuring that the monitoring system can work in an emergency for about two hours, so that the pressure, flow and temperature parameters can continue to be monitored and used, further ensuring the operation safety of the electric throttle manifold.

[0042] The electric throttling manifold operates in real time, with inlet-side pressure and flow transmitters monitoring high-pressure fluid pressure and flow around the clock. Operating in a primary throttling channel, the high-pressure fluid flows through multiple throttling and pressure reduction mechanisms, including electric and manual throttle valves, reducing pressure and flow to pre-set values. These values ​​are set by the central control station or local controls. The primary pressure and flow transmitters monitor low-pressure and low-flow data in real time. The secondary throttling channel operates on the same principle, with different throttling and pressure reduction values ​​set according to production conditions. All data values ​​monitored at each level are transmitted in real time to the central control station's integrated electrical cabinet CPU system and the station-side management terminal. The operation of this process flow is determined based on actual production pressures on site.

[0043] Based on the pressure and flow parameters monitored by the transmitters, the central control station can issue instructions for the corresponding electric valves to switch or adjust their opening ratios. Temperature transmitters in each link monitor the temperature parameters of the fluid in the corresponding pipeline. The configuration of multiple intelligent transmitters and intelligent electric valves ensures the accuracy and real-time nature of various data monitoring and acquisition, as well as the rapid and stable output of each switch valve instruction. Both single-well and multi-well electric choke manifolds offer complete closed-loop control capabilities.

[0044] The electric gate valve and electric throttle valve installed in the electric throttle manifold have the function of on-site operation of opening, closing or percentage opening, and can switch between local and remote control modes.

[0045] The control accuracy of the percentage opening of the electric throttle valve set in the electric throttle manifold reaches 1%, thereby performing precise throttling and pressure reduction to accurately control the fluid in the throttle manifold.

[0046] Technical improvements:

[0047] The throttle manifolds are all electrically controlled, featuring electric gate valves and electric throttle valves, equipped with advanced intelligent electric actuators. They feature bus and analog control functions, and fully digitized control and feedback information, improving control accuracy and reducing failure rates. These features comply with national standards for explosion-proof protection levels. These replace the hydraulic controls used in most previous throttle manifold valves, which were characterized by heavy and cumbersome hydraulic lines, noisy electric pumps, and the potential for widespread hydraulic oil leakage and environmental pollution over time. Furthermore, these controls address the growing trend of electrified control for electromechanical equipment in the oil and gas industry.

[0048] This system enables wireless, automated, and intelligent monitoring of electric choke manifold parameters at multiple well sites. The single-well electric choke manifold is equipped with a pressure transmitter, flow transmitter, temperature transmitter, electric gate valve, and electric throttle valve on the inlet side; a pressure transmitter, flow transmitter, temperature transmitter, and electric throttle valve on the primary throttle pressure-reducing side; a pressure transmitter, flow transmitter, temperature transmitter, and electric throttle valve after the secondary throttle pressure-reducing side; and a pressure transmitter and electric throttle valve on the outlet side. The configuration of multiple intelligent transmitters and intelligent electric valves ensures the accuracy and real-time nature of all types of monitoring and data collection, as well as the rapid and stable output of each on-off valve command. Both single-well and multi-well electric choke manifolds possess complete closed-loop control capabilities.

[0049] Each electric throttle manifold is equipped with a terminal electrical control cabinet. The central control station is equipped with a central integrated electrical control cabinet. When the entire control system is powered on and the communication and control programs programmed for the master controller are executed, the master controller in the central integrated electrical control cabinet connects to the terminal-side wireless communication units of the terminal electrical control cabinets via the master wireless communication unit to control the terminal-side controllers of the terminal electrical control cabinets, establishing a stable wireless communication framework for exchanging digital signals. The overall communication range is within 10 kilometers in an open, unobstructed environment.

[0050] The central control integrated electrical control cabinet can wirelessly control up to ten single-well electric choke manifold terminal cabinets. This ensures precise throttling control for multiple wells within a single oil and gas production area. Pressure, flow, and temperature data are accurately monitored, recorded, and regularly saved in real time around the clock, providing alarms for abnormalities. The central control station utilizes an integrated host computer and large-screen display for monitoring. The host computer control program runs via open-user TCP communication with the main controller, monitoring all intelligent transmitter data and controlling all intelligent electric valves. The host computer shares interface data with the central control screen via a TV-BOX connection. In the event of abnormal data, emergency opening and closing of electric gate valves or adjustment of the percentage opening of the electric choke valves can be implemented to meet the control requirements of the electric choke manifold production process. This ensures that wellhead throttling and pressure control requirements are met, ensuring long-term safe operations. This reduces operator workload, ensures accurate and timely operation data for the wellhead choke manifold, and enables unified monitoring, management, and scheduling of multi-well operations.

[0051] The host computer control interface software, through the cloud platform control box's communication connection, can upload and share data with the upper-level management server, enabling information and data sharing. The cloud platform control box is internally equipped with cloud mobile communication capabilities. Further explanation is that this function uses third-party cloud platform software.

[0052] Beneficial technical effects:

[0053] The throttle manifolds are all electrically controlled and are equipped with electric gate valves, electric throttle valves, pressure transmitters, flow transmitters, and temperature transmitters, all of which comply with relevant national standards for explosion-proof protection levels.

[0054] It realizes wireless automation and intelligent monitoring of electric choke manifold parameters in multiple well sites. It configures the electric choke manifold of a single well with pressure transmitter, flow transmitter, temperature transmitter, electric gate valve and electric throttle valve at the inlet, pressure transmitter, flow transmitter, temperature transmitter and electric throttle valve for the first-level throttling and pressure reduction, pressure transmitter, flow transmitter, temperature transmitter and electric throttle valve after the second-level throttling and pressure reduction, and pressure transmitter and electric throttle valve at the outlet.

[0055] Each electric throttle manifold unit is equipped with a terminal electric control cabinet. The central control station is equipped with a central control integrated electric control cabinet. The terminal electric control cabinet is connected to the main wireless communication unit of the central control integrated electric control cabinet through the terminal-side wireless communication unit.

[0056] The central control integrated electrical control cabinet can wirelessly control up to 10 single-well electric choke manifolds. This ensures accurate, real-time monitoring, recording, regular storage, and abnormality alarms for choke manifolds across multiple wells within a single oil and gas production area. All data, including throttling, pressure, flow, and temperature, can be accurately monitored, recorded, and regularly stored at the central control station. An integrated host computer and large screen monitor can be used to monitor and view all data. If abnormal data is detected, emergency opening and closing of electric gate valves or adjustment of the electric choke valve opening percentage can be implemented to meet wellsite production process requirements and maintain long-term safe operations.

[0057] Data can be uploaded and shared with the upper-level management server, reducing the workload of operators and ensuring accurate and timely operation data of the wellhead choke manifold. Multi-well operations can be uniformly monitored, managed, and dispatched without laying a large number of communication cables.

[0058] Land oil and gas fields are located in the wilderness, deserts and Gobi, and the open-air field environment and working conditions are very harsh. With the implementation of this technical solution, a large amount of work can be completed in the central control station, reducing the labor intensity for oil and gas field operators and improving a certain degree of work comfort.
