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.
