Abstract


In oil exploration , production activities , timely and accurate information to the wells of the well temperature and the well pressure parameters is very important . The wells underground is a high temperature , high pressure , corrosion , the harsh environment of space is small , well parameter transmission system to thousands of meters deep downhole pressure and temperature parameters in real time to achieve accurate transmission Inoue . In our intelligent wells parameters measured depth of the transmission system has not exceeded 20 meters , and influenced by the well conditions of the production wells , the practical application of high degree of difficulty , the subject of design and development of the transmission system of 3,000 meters above the well parameters . Papers innovative using the pressure difference between automatic retractable cord float the wireless transponders structure , the use of modern communications technology to complete the dynamic long-distance transmission parameters wells . The design characteristics of the system can be adapted to different wells well conditions , the transmission distance above 3,000 meters , and the lower device power consumption of the entire system , can automatically complete the long - term measurement and transmission of downhole parameters . The paper introduced the the bottomhole transmission system , float forwarding system hardware and software design , and Inoue monitoring system design . Bottomhole launch system XC3S100E FPGA - based processor to achieve real-time collection of well pressure and temperature parameters , modulation of the data at the same time to complete 2FSK digital FM technology . Float to forward system uses a wake-up function 16-bit ultra-low power MSP430 series microcontroller as the CPU to complete decoding wireless transceiver CC1100 wireless repeater . Inoue, real-time monitoring system can display the well pressure and temperature values ??, and through a simple operation to make the whole system is in sleep or wake-up mode , reducing the power consumption of the system . The field test , the entire system in real-time and accurate completion of the transmission parameters of 3000 meters on the wells . The power consumption of the system can also achieve the objective set in advance , in the oil well environment working continuously for a week .
