[0002] As global resources become increasingly valuable, oil, as the lifeline of the national economy, is becoming increasingly important to ensure its stable production. With the continuous advancement of modern technology and the continuous improvement of the level of automation in production management, the industry's requirements for the digitalization and automation of oilfield pressure-driven operations are becoming increasingly higher, and the original on-site manual water injection work mode can no longer meet the needs of work. This mode is not only noisy, has a poor environment, is not conducive to long-term manual operations, but also cannot meet the requirements of online monitoring of water injection equipment. Therefore, the development of a remote control system based on PLC and mobile networks that can adapt to the needs of oilfield development and water injection, and in which each operation link supports and relies on each other, has very high practical application value and practical significance for real-time monitoring of the operating status, working parameters and status changes of water injection site equipment, and rapid scientific judgment.

[0003] In the Chinese patent application with application number: 202010233697.2, a DMZ-based oil and gas industrial Internet data processing system is involved, including multiple DTU acquisition and transmission units, DMZ subsystem and industrial control subsystem. The multiple DTU acquisition and transmission units collect data signals from remote well stations in oil and gas fields, and interact with the DMZ subsystem through the communication operation network. The DMZ subsystem is deployed in the isolated service area of ​​the communication operator. On the one hand, it communicates with the multiple DTU acquisition and transmission units, and on the other hand, it responds to data acquisition requests and remote control requests from the intranet of the oil and gas field enterprise. The industrial control subsystem is deployed inside an industrial control network of the oil and gas field, and communicates with the office network and the DMZ subsystem through a network switch or firewall to collect, monitor and control all well station data. The system fully takes into account the network security and data transmission rate of data processing, and ensures the information privacy, high speed and industrial control security of remote data acquisition in oil and gas fields.

[0004] In the Chinese patent application with application number: CN202110017627.8, a data acquisition and access system is involved, which belongs to the field of oilfield information technology. The system includes a data acquisition part, a cloud server, a DMZ channel and an intranet server. The data acquisition part is located at the acquisition site, the cloud server is located outside the enterprise, and the intranet server is located inside the enterprise. The cloud server is used to send a data acquisition request to the data acquisition part when the data acquisition conditions are met, receive the target data sent by the data acquisition part, and send a first message including the target data to the DMZ server through the address information of the DMZ server in the DMZ channel. The DMZ server is used to determine the address information of the intranet server according to the correspondence between the stored address information of the DMZ server and the address information of the intranet server, and send a second message including the target data to the intranet server through the address information of the intranet server. Using this application, a system for accessing the collected data to the intranet of an oilfield enterprise is provided.

[0005] In the Chinese patent application with application number: CN202010227981.9, an oil and gas IoT data acquisition system based on NBIoT technology is involved, including NB-IoT area, DMZ area, oilfield industrial network area and oilfield office network area. The NB-IoT area collects and stores real-time data of the oil and gas production site and transmits it to the DMZ area. The DMZ area collects and stores data of wireless communication equipment, and transmits the data of the site and the data of wireless communication equipment to the oilfield industrial network area.
