5G+ Intelligent Oilfield System Monitoring Solution

I. Existing difficulties in oilfield management

1、Difficult to unify management

　　The requirements of how the management personnel can achieve real-time monitoring of oil wells, RTU management information, angular displacement sensors, pressure sensors, load sensors, broadcast lighting information, emergency adjustments, as well as part of the WiFi LAN coverage and other diversified businesses through the system backend vary greatly, and it is impossible to achieve unified management.

　　2、Massive transformation project

　　Most of the sites such as oil wells and pressure stations that have been constructed at present have a huge demand for renovation, and how enterprises can quickly deploy and reasonably realise the purpose of intelligent renovation is the existing problem.

　　3、Complex operating environment

　　Oilfield is usually distributed in sparsely populated swamps, deserts, basins and shallow seas and other areas, the working environment is relatively special, the site guards and maintenance personnel less, staff inspection sites are farther away, resulting in inspection work; and the oilfield working environment has a high degree of risk, once leaked, will have a significant impact on the human body and the surrounding environment, the traditional operating environment is immeasurable harm.

　　4、Inefficient management

　　Well patrol, well data entry, wellhead machinery start and stop work requires a large number of personnel to complete, management difficulties, high manpower costs, how to improve the production management efficiency, to solve the oilfield field manpower input is limited; to reduce the number of experts to run wells, wells to carry out on-site technical support to reduce costs and improve efficiency is a modern intelligent oilfield need to consider the factors.

II. Construction Objectives

As an important link in the oil gathering system, the importance of stable operation is self-evident. It is a major initiative to improve the level of safety production management to establish an integrated monitoring system covering all oilfields using an integrated data network, with video monitoring as the core to promote visual production management.

In view of the system status quo in oilfields, ChenAnIoT uses 5G industrial routers, 5G industrial CPE, 5G IoT RTU network cameras and other monitoring terminal equipment to establish a modern integrated monitoring system adapted to the safety production of oilfields, to manage the front-end operation, business, and equipment, etc., and to satisfy the needs of centralised management, hierarchical viewing, and graded supervision of the higher-level platforms, and to realise multilevel networking and cross-region Monitoring

III. Programme introduction

The combination of ChenAnIoT 5G industrial router and intelligent oilfield is to combine automation control, information collection, transmission and processing technology, remote monitoring and control, wireless information transmission, big data transmission and processing, etc., to realise the intelligent oilfield exploitation, improve the efficiency of oilfield exploitation, reduce the cost and add value, and improve the safety of personnel operation.

　　2.1 System Composition

　　ChenAnIoT 5G Intelligent Oilfield System mainly consists of wellhead monitoring terminal, ChenAnIoT 5G industrial router and system management platform. Through real-time detection of wellhead parameters, well status parameters collected by well RTU collector are sent to the database server of the oil extraction plant through ChenAnIoT 5G industrial router, so that each department of production management can grasp the working status of wells in time, shorten the well fault It can shorten the processing time, improve the rate of opening wells, increase the crude oil production, improve the working efficiency, provide a brand new means for the fine management of pumping wells, and is the ideal production automation product for the oilfield.

2.2 System engineering equipment composition

　　(1) Sensor components: tensile force sensor, angular displacement sensor, temperature sensor, pressure sensor and so on.

　　(2) Wellhead monitoring terminal: power supply module, acquisition module, Siksin 5G industrial router

　　(3) System management platform

　　2.3 System Functions

　　The system mainly collects parameters such as pumping unit three-phase voltage, current, active power, power factor, daily power consumption, cumulative power consumption, oil wellhead back pressure, wellhead temperature, light pole load and power diagram, shutdown, etc., and carries out corresponding data processing and storage.

　　(1)Give alarm information for abnormal conditions such as pumping well shutdown, parameter overrun, pumping rod break-off, pumping rod jamming, and so on.

　　(2)With data power-down protection function, it can save the set parameters and historical data for a long time. Remotely realise load overload shutdown control and timed start-up control of the pumping machine.

　　(3)Remotely realise parameter configuration and setting of over-limit value for monitoring terminal.

　　(4)Automatically record the working process of the oil pumping machine, accumulate the start-up time and shutdown time, and save the historical information.

　　(5)With functions such as static data browsing and editing: including data on pumping machine model, configured motor model, oil well number, stroke, line name, range, alarm upper and lower limits, oil well condition, etc. It can also add newly opened oil wells, delete shutdown oil wells, and modify the basic data of operating wells.

　　(6)It has the functions of real-time trend and historical trend monitoring of parameters such as schematic diagram, current diagram (or power diagram), current, voltage, temperature, pressure, etc., which makes it easy to understand the parameter changes over a long period of time, and facilitates quick analysis.

　　(7) Protection design can be carried out according to user needs . For example: by analysing the pressure gauge data of each transmission link, the phenomenon of theft can be effectively avoided.

IV. Advantages of the programme

Combining 5G with smart oilfield, using big data + AI technology, it realises the rapid transmission and intelligent processing of data in the oil field and the sharing of oil data, which is conducive to guiding the practical problems of today and the development of the oil field in the future, broadening the field of petroleum, realising the innovation and creativity of petroleum equipment and technology, realising the modernisation of the petroleum industry, and reducing the gap in petroleum development, as well as contributing to the world’s petroleum development Make contribution to the world’s oil development.
