Background and challenges:

When Hou Qijun, deputy general manager of PetroChina Changqing Oilfield, interpreted the "Thirteenth Five-Year Plan" for the second development plan of Changqing Oilfield in 2016, he has focused on analyzing the integrated, intelligent and scientific development route of oilfield exploitation.

On May 30, 2019, a large-scale central meeting with more than 200 people from Changqing Oilfield, Chang'an University, and Huawei was held. The core idea is "Big Data, Artificial Intelligence and Smart Oil and Gas Field Construction", which reflects oilfield companies’ Great attention and determination to construction.

The main problems facing the system at this stage:

1) There are many ways of equipment communication-although the unit intelligence has been realized, there are many single equipment manufacturers, which are unique, which causes the actual remote management to be chaotic, which is not conducive to the real intelligent production management. Through data integration The platform is compatible with all single devices and realizes intelligent management in the true sense.

2) Manual inspection is time-consuming and labor-intensive-this method will cost a lot of manpower, material resources and time, and later data query is also time-consuming and laborious;

3) Lack of an intuitive data display platform-the administrator needs to use multiple professional software to view the data separately during use. When there are errors in the data, there is a lack of comparison;

4) Slow response to emergencies-when the oil and gas pipeline leaks, the managers first need to check the pipeline design drawing, use experience to judge, analyze the cause of the accident, find out the treatment plan, and then arrange personnel to carry out emergency repairs, from the leak to closing the valve The longer the time, the greater the leakage, the greater the risk and the more economic losses;

5) Single inspection method-security inspections and the handling of security incidents have great blindness and uncertainty. Not only will there be situations that cannot be inspected, but even if inspections are made, there will still be errors in the judgment of security response strategies, Issues such as insufficient execution in time. This will not only cause irreparable economic losses, but also serious casualties.

The goal of building:

Compared with the traditional operation mode, it greatly reduces a lot of man-made operation links, and the control speed and control accuracy have also been significantly improved, and the work efficiency has been improved to ensure safety, stability and reliability during operation. The pipeline body and surrounding environment data are true and accurate throughout the life cycle, and the standards are unified. Accurate collection of pipeline information, data sharing, panoramic visualization display, accurate perception of pipeline security status Based on the pipeline full life cycle database, the pipeline business systems are integrated to eliminate information Isolated islands, to achieve coordinated linkage and precise identification of material demand information, implement the new model of "collection and storage + precise warehousing", create an intelligent, agile, lean and efficient supply chain operation plan that automatically optimizes in real time, improves operation efficiency, reduces operation costs, and implements integrity management , Timely maintenance and repair, early risk prediction, early warning of hidden dangers, automatic emergency triggering, automatic generation of emergency plans, active push of emergency resources, full utilization of accident cases, and realization of pipeline safety and controllable intelligent production management control system: remote monitoring and control system, wellhead production Data collection, storage, calculation, control (switch well), drainage and gas recovery, intelligent security video monitoring, data communication and energy consumption management functions are the management platform for the intelligent management production control system.

solution:

The oil and gas pipeline network full-time intelligent management system solution is mainly used in the construction and transformation of the oilfield branch/administration level digital oilfield pipeline network security. Realize full-time monitoring of oil and gas pipeline network, and finally realize pipeline leakage, pipeline depth, exposure, and geological deformation prediction through optical fiber temperature measurement and vibration technology; transmission medium leakage, endangering external intrusion warning; emergency interception of medium source when major leakage accidents occur. The system composition is as follows:

The full-time intelligent management system of oil and gas pipeline network adopts optical fiber temperature measurement and vibration measurement technology, Internet of Things, and 5G application technology. Under the guidance of the design principle of "standardization, integration, and intelligence", it adopts standardized industry products to achieve the following functions

(1) Establish an optical fiber security detection system to realize the real-time monitoring of the entire line of transportation pipelines and realize the centralized control of security automation and intelligence;

(2) Establish a data center with traceable historical information and generate a basic data group of equipment data, process, process and other information, so as to achieve the digital control of the all-round status data and equipment information of the optical fiber security detection system;

(3) Establish a comprehensive management platform for the optical fiber security detection system to achieve one-stop management, data display, predictive maintenance of equipment failures, and portable smart mobile terminal APP for all transportation pipelines;

(4) Establish comprehensive and multi-level defense-in-depth measures, build a defense-in-depth integrated industrial control system security defense system, comprehensively improve the self-immunity and anti-attack capabilities of the integrated management platform of the optical fiber security detection system, and ensure the country's key information foundation Safe operation of facilities.

Program highlights:

1) The data platform function includes the storage and classification of data such as safe operating status data, equipment information, and process parameters of major systems, and can query and trace historical data;

2) The essence is to realize the integrated management of gas well production. It exists in the entire life cycle of the gas well. The final foothold is refined management and unmanned management. At the same time, it has the ability to learn, conduct scientific exploitation and rational planning.

3) In the end, a small or unmanned wellhead will be realized, a scientific and reasonable natural gas exploitation mode will be realized, and the entire exploitation period will be extended. It can realize the integrated self-collection and learning of "maintenance, repair, prevention and control", and make accurate analysis and judgments, provide corresponding solutions and measures in time, and truly save labor costs, realize scientific and reasonable oil and gas exploitation, and realize The goal of sustainable development.

4) Accurate collection of pipeline information, data sharing, panoramic visual display, accurate perception of pipeline safety status

5) Accurately identify material demand information, implement a new model of "collection and storage + precise warehousing" to create an intelligent, agile, lean and efficient supply chain

6) Realize early risk prediction, early warning of hidden dangers, automatic emergency triggering, and maintenance timing.
