Wireless sensor network based drilling well site monitoring system

Abstract

A wireless sensor network technology based drilling well site monitoring system comprises a single-well wireless sensor monitoring network, a cross-well wireless relay network and a central control data analysis system. The single-well monitoring network adopts a group of sensor nodes to take charge of collecting the drilling condition data, is connected with all the single-well networks in the well site by relay nodes to form a secondary cross-well wireless relay network and realizes long-distance connection with a central control room by way of multihop. The central control data analysis system provides users with various data services and such services as visualized monitoring, control, management and the like. In the system, the used sensor nodes adopt sensor module and computing and communication split type design so as to be convenient for matching different types of sensors. The cross-well network adopts random networking, thus improving the flexibility and expandability of the system.

Description

technical field [0001] The invention relates to a monitoring system for a drilling well site, in particular, it uses wireless sensor network technology to realize the monitoring of the working state of the drilling well site and the associated well head.

AI Technical Summary

Problems solved by technology

[0004] (1) If the working range of the well site is too large or the terrain is relatively complex, it will face difficulties in the construction of the cable network laying project and various emergencies;

[0005] (2) The laying of long-distance cables and the supports used for overhead lines will cause certain electromagnetic pollution and environmental damage, and increase the project cost;

[0006] (3) The working environment of the well site is relatively complicated, and it is easy to cause accidental damage to the fixed cables, equipment and staff;

[0007] (4) In the production activities of the well site, the conditions of various engineering equipment and personnel are constantly changing, and the later maintenance of fixed network facilities is very difficult

[0008] Due to the above limitations, the technical solutions of the existing drilling well site monitoring system are not conducive to promoting the automation of well site production and the improvement of production efficiency
