Scheme requirements
An oil production field in an oil field consists of multiple oil wells, metering rooms, manifold valves, transfer stations, joint stations, crude oil export systems, oil tanks and oil fields. The composition of other dispersed facilities, the working status of various facilities in the entire oil extraction field and the data of the produced oil products (mainly temperature, pressure, flow, etc.) are directly related to the stability of oilfield production and the quality of crude oil.
Wireless communication for oil and gas drilling
For domestic drilling safety protection devices and monitoring operation technology, there are problems such as single function, poor on-site adaptability and poor integration. Drilling monitoring needs to be automated and intelligent Protection is integrated, field application monitoring parameters are collected wirelessly, realizing the functions of drilling pump pressure protection, traveling car protection, overflow and lost circulation real-time monitoring and qualitative, intelligent automatic grouting, real-time display of drilling parameters and curves, etc., to maximize The risk caused by the abnormal high pressure of the drilling pump is reduced, and the overflow accident caused by the untimely grouting of the drilling trip is avoided. The risk of oil drilling is reduced, and the safety of life and property is guaranteed.
At present, most of the oil production data are checked by manual daily and regularly. Due to the large number of oil wells and their distribution range from tens to hundreds of square kilometers, this method will inevitably increase the labor intensity of workers and affect the real-time and even accuracy of equipment monitoring and oil production data.
Technical deployment
The real-time monitoring unit of oil and natural gas drilling sensors has three parts, the drilling fluid performance monitoring instrument, the geological logging monitoring instrument and the drilling engineering parameter monitoring instrument. The real-time monitoring unit has many sensors and monitoring instruments, and the monitored signals are collected by Xinyangbang DTU serial port 485 to wireless transmission.
Oil and natural gas drilling wireless communication
Online real-time monitoring of drilling fluid viscosity, shear force, water loss, density, import and export flow and other performance indicators. The automatic sand and fluorescence content analyzer can not only monitor gaseous alkanes in real time, but also monitor the content of heavy alkanes in cuttings in real time. Combined with coring, the oil saturation of different layers can be comprehensively obtained. Real-time monitoring of the flow of drilling fluid import and export, and the use of instruments instead of labor effectively prevents blowouts and stuck drills.
DTU data transmission terminal transmits data in real time to the designated IP database, computer equipment and multiple display terminals and center console. The center console is located in the control room of the drilling platform. Data calculation processing is set up in mud, technicians, etc. The real-time monitoring of downhole and surface parameters during the drilling process, remote monitoring, remote decision-making and digital drilling have become the development trend of drilling, enabling the realization of “digital oilfields”.
