Research of Modern Drilling Instrument System Based on the Wireless Networks

The drilling engineering is a high-cost and high-risk project. So the drilling projects have introduced a series of equipments and devices as drilling supplement, whose parameter showing provide some dynamic information, and provide scientific evidence for technical staffs such as the drillers. The wireless communications technology makes the communication between drilling sites and oil bases be more smooth along with increasing the bandwidth of wireless network. The technology provides new possibilities for improvement of drilling equipment system. At present, the oil industry internationalization and many oil fields locating in the turbulent areas request the site and the base to be connected as a whole, so, the demand for the staff in base controlling the on-site equipment grows. This article presents an architecture for the drilling instrument systems connecting the drilling field and the base of oil field. It establishes the two-way data transmission channel, through which the real-time acquisition data, system configuration data and operating commands can communicate with each other. It collects the signals from sensors in drilling equipments, and transmits these signals to the on-site application and monitoring systems, then stores them in the on-site local databases, and finally the data will be calculated professionally in the base and be stored in the global database. Personnel at the base can monitor and control the well fields, and they can also complete the on-site equipment operation, system software settings, sensor calibration and so on. This system discussed in this article reduces the number of on-site personal, improves the utilization rate of expert in base and reduce the risk of personnel in risk areas and the cost of drilling.
