Huabei Oilfield is one of the important oil producing areas in my country. The developed oil and gas fields are mainly concentrated in the central Hebei and Inner Mongolia regions of Hebei Province. The exploration area is nearly 200,000 square kilometers. There are about 3 billion tons of oil resources in the exploration area, and 1.1 billion tons have been proved, with a proven degree of 36.7%. As a high-precision technology, oil exploration has always been monopolized by foreign manufacturers, and it is difficult to do without excellent products and technologies. Enter the field of oil exploration. However, domestic manufacturers have not been able to enter the oil exploration industry due to imperfect technology or various reasons.
The wireless communication oil well monitoring system on the coast of Kunlun has been perfectly applied in the North China Oilfield. This is not only a simple system application, but also highly recognized by domestic manufacturers. The Chinese finally have their own system to collect their own oil. ! This is a great pride and an incentive for many domestic manufacturers!
1. The sending end of WST01 wireless sensor is connected to angular displacement sensor, load sensor and flow sensor to collect relevant sensing data and send it to NRM02 wireless communication receiving module;
2. The NRM02 wireless communication receiving module transmits the received data to the PLC;
3. The PLC is then sent to the monitoring center by connecting the GPRS device, so as to realize the remote monitoring of oil well exploration;
This case has been maturely applied in Huabei Oilfield. The product has high stability and controllable cost. It has been widely praised by users, and has been successively promoted in the exploration of other oilfields of PetroChina. classic application case.
It is mainly used in the field or occasions where the supporting power supply environment is inconvenient, or the existing wired signal acquisition needs to realize wireless upgrade and other working conditions. Through the host computer at the receiving end, the configuration can be directly used to monitor the field data in real time.

Summarize:
This system involves angular displacement sensing monitoring, load sensing monitoring, flow sensing monitoring, and wireless communication transmission, and finally realizes efficient and stable remote oil well monitoring, so that the staff can know the oil well exploration status on site without having to visit the site in person. Improve the efficiency of work and the degree of remote automation in my country. With the advancement of my country’s informatization, the application of this system will be applied in more oil fields, and Kunlun Coast will continue to improve its own technology and products to meet new needs.
