Description

Technical Field

[0001] The present invention relates to the technical field of equipment control, and particularly to an intelligent analysis and control system for edge data of oil wells and oil production and pumping equipment. Background Art

[0002] The existing intelligent analysis and control systems for oil well production and pumping equipment have the following problems:

[0003] Insufficient data accuracy: Data acquisition devices such as sensors may experience problems such as decreased accuracy and failures during long-term operation in the harsh oil well environment, resulting in inaccurate collected data and affecting the basis of intelligent analysis.

[0004] Poor timeliness of manual data collection: Many well positions are currently still using the method of manually placing dynamometer cards on-site for regular and fixed-point collection, which increases labor costs and has poor timeliness of collected data, and there are problems such as misjudgment and missed judgment.

[0005] Poor data transmission stability: The oil well environment is complex, and signal transmission is easily interfered. Especially during long-distance transmission, data packet loss, transmission interruption, etc. may occur, and the real-time and integrity of data cannot be guaranteed.

[0006] Poor system compatibility: There is a lack of unified standards and interfaces between different manufacturers, different types of production and pumping equipment, and intelligent control systems, making it difficult to achieve seamless integration and collaborative work, resulting in a serious information island phenomenon.

[0007] Lag in data analysis and early warning: The currently commonly used data acquisition and diagnosis method is that the data of oil wells and production and pumping equipment is transmitted to the remote data platform at fixed intervals through wired or wireless means, and the remote data platform conducts unified analysis and management, and analyzes and diagnoses the abnormal data. In this way, there are many data transmission nodes, and there is a risk of data loss. The fault early warning information of oil wells and oil production equipment lags behind, affecting production operations and equipment safety.

[0008] Therefore, there is an urgent need in this field for a technical solution that can intelligently control oil well production and pumping equipment.
