Description

Technical Field

[0001] This invention relates to the field of intelligent linkage system technology for skid-mounted processes, and more particularly to intelligent linkage system and linkage method for skid-mounted processes. Background Technology

[0002] Skid-mounted intelligent linkage systems are mainly used to realize the intelligent collaborative work of multiple devices or units in the process flow, so as to improve production efficiency, reduce energy consumption, and enhance safety and flexibility. Specifically, the system can be applied to multiple industries and fields, including but not limited to petroleum, chemical, natural gas, pharmaceutical, and food processing, for handling the transportation, mixing, separation, and reaction of fluids or solids. However, when using skid-mounted intelligent linkage systems, they usually only include basic modules such as data acquisition, signal transmission, wellhead high-pressure throttling, chip removal, and outlet valve groups, for basic processing and transportation of natural gas. Furthermore, they cannot effectively remove moisture and heavy hydrocarbons during the natural gas processing, resulting in relatively low natural gas quality. Summary of the Invention

[0003] To overcome the problem that when using skid-mounted intelligent linkage systems, they typically only include basic modules such as data acquisition, signal transmission, wellhead high-pressure throttling, chip removal, and outlet valve groups for basic natural gas processing and transportation, and cannot effectively remove moisture and heavy hydrocarbons during the natural gas processing, resulting in relatively low natural gas quality.

[0004] The technical solution of this invention is: a skid-mounted intelligent linkage system and linkage method, comprising: Data acquisition module: used to acquire data from oil and gas field wellheads; Signal transmission module: Used to transmit oil and gas field wellhead data acquired by the data acquisition module; Wellhead high-pressure throttling module: used to throttle and reduce the pressure of high-pressure natural gas produced from the wellhead; High-efficiency chip remover module: used to remove solid impurities carried in natural gas; Integrated heating, separation, and metering module: used to remove moisture and heavy hydrocarbons from natural gas; Outbound valve assembly module: used to transport processed natural gas to downstream pipelines or user terminals; Chemical dosing module: Used to add various chemical agents to the system; Venting and separating module: Used to vent the gas in the system.

[0005] Preferably, the data acquisition module includes multiple types of sensors, such as pressure sensors, temperature sensors, and flow sensors. These sensors are used to collect various data from oil and gas wells in real time, including key parameters such as pressure, temperature, flow rate, liquid level, and power, as well as indicators related to potential safety risks.

[0006] Preferably, the information transmission module includes a 3G information transmission module, a 4G signal transmission module, a Bluetooth transmission module, and a GPS signal module. The data transmission module intelligently judges the signal strength and uses the 3G information transmission module, 4G signal transmission module, Bluetooth transmission module, and GPS signal module to establish a stable signal transmission chain, transmitting the data collected by the data acquisition module to the wellhead high-pressure throttling module.

[0007] As a preferred option, the wellhead high-pressure throttling module is used to throttle and reduce the pressure of the high-pressure natural gas produced at the wellhead. By using the wellhead high-pressure throttling module, it can be ensured that the pressure of the natural gas is reduced to a safe range before entering the subsequent processing flow, thereby protecting the downstream equipment from high-pressure impact and improving the safety and stability of the system.

[0008] As a preferred option, the high-efficiency chip remover module is installed after the high-pressure throttling module at the wellhead to remove solid impurities carried in natural gas, such as sand and rust. If these impurities enter subsequent equipment, they may cause wear and blockages, affecting the normal operation of the system. The high-efficiency chip remover module can effectively protect the system equipment and extend its lifespan.

[0009] Preferably, the high-efficiency chip remover module reduces the number of impurities entering the system, thereby reducing the equipment failure rate caused by impurities, thus improving the stability and reliability of the entire system. At the same time, it reduces the equipment cleaning and maintenance work caused by impurity accumulation, further reducing the system's maintenance costs.

[0010] As a preferred option, the integrated heating, separation, and metering module is used to heat natural gas, which can remove moisture and heavy hydrocarbon components, thereby improving the quality of natural gas. At the same time, the integrated heating, separation, and metering module also has a precise flow metering function, which can provide accurate data support for production management and help achieve refined management.

[0011] Preferably, the integrated heating, separation, and metering module effectively removes moisture and heavy hydrocarbon components from natural gas by heating it. This not only improves the quality of the natural gas but also prevents moisture and heavy hydrocarbons from condensing and clogging subsequent pipelines and equipment, ensuring smooth system operation. Furthermore, the natural gas with removed moisture and heavy hydrocarbons is of higher quality, better meeting the needs of downstream users, thereby enhancing the product's market competitiveness.

[0012] As a preferred option, the outgoing valve assembly module is used to transport the processed natural gas to the downstream pipeline network or user end. Through precise control of the valve assembly, the direction and flow rate of natural gas can be flexibly adjusted to ensure a stable supply of natural gas and safe operation of the system.

[0013] Preferably, the chemical refueling module is used to refuel the system with various chemical agents, such as corrosion inhibitors and inhibitors. These agents play an important role in maintaining the normal operation of the system and extending the life of the equipment. For example, corrosion inhibitors can prevent equipment corrosion and extend the service life of the equipment; inhibitors can prevent certain components in natural gas from reacting under specific conditions, which could lead to system failure.

[0014] Preferably, the venting and liquid separation module is used to vent the gas in the system and separate and discharge any liquid that may accumulate. The venting and liquid separation module can ensure the safety of the system under abnormal operating conditions and prevent system failures caused by gas accumulation or liquid blockage.

[0015] The intelligent linkage method for skid-mounted processes includes the following steps: S11: Real-time acquisition of various data from oil and gas wells via the data acquisition module, such as key parameters like pressure, temperature, flow rate, liquid level, and power consumption; S12: Establish a stable signal transmission chain using the signal transmission module to transmit the data acquired by the data acquisition module to the subsequent processing module; S13: The high-pressure natural gas produced from the wellhead is throttled and depressurized using the wellhead high-pressure throttling module to ensure that the pressure of the natural gas is reduced to a safe range before entering the subsequent processing flow; S14: The high-efficiency chip remover module removes solid impurities such as sand and rust carried in natural gas, protecting downstream equipment from the effects of these impurities. S15: The integrated heating, separation, and metering module is used to heat natural gas, remove moisture and heavy hydrocarbon components, improve natural gas quality, and perform accurate flow metering; S16: Various chemical agents, such as preservatives and inhibitors, are added to the system through the agent dispensing module to maintain the normal operation of the system and extend the equipment life; S17: The final outgoing valve group module delivers the processed natural gas to the downstream pipeline network or user end. Through precise control of the valve group, the direction and flow rate of natural gas can be flexibly adjusted.

[0016] The beneficial effects of this invention are: 1. Compared to traditional skid-mounted intelligent linkage systems, which typically only include basic modules such as data acquisition, signal transmission, wellhead high-pressure throttling, chip removal, and outlet valve groups for basic natural gas processing and transportation, and which cannot effectively remove moisture and heavy hydrocarbons during natural gas processing, resulting in relatively low natural gas quality, this skid-mounted intelligent linkage system adds a heating, separation, and metering integrated module. This module can heat the natural gas to effectively remove moisture and heavy hydrocarbon components, while providing accurate flow metering functions, providing more comprehensive and accurate data support for production management. 2. The integrated heating, separation, and metering module effectively removes moisture and heavy hydrocarbon components from natural gas by heating it. This not only improves the quality of the natural gas but also prevents moisture and heavy hydrocarbons from condensing and clogging subsequent pipelines and equipment, ensuring smooth system operation. Furthermore, the natural gas after removing moisture and heavy hydrocarbons is of higher quality and better meets the needs of downstream users, thereby enhancing the product's market competitiveness. 3. The high-efficiency chip remover module reduces the number of impurities entering the system, thereby reducing the equipment failure rate caused by impurities, which improves the stability and reliability of the entire system. At the same time, it reduces the equipment cleaning and maintenance work caused by impurity accumulation, further reducing the system's maintenance costs. Attached Figure Description
