Aiming at problems that formation pressure measurement while drilling is difficult and timeconsuming

meanwhile

the descending and sticking of downhole tool are potential risks

in allusion to problem above

the formation pressure measurement and control system is proposed based on dual-processor.By pressure transducer

down well pressure can be measured in the process of measurement while drilling（ MWD）

and the formation pressure value is collected and processed by the master processor TMS320F2812

the electromagnetic valve is intelligently controlled by the slave processor

and the shunt

commutator and the actuator are coordinated well

so that the real-time formation pressure data is obtained.The experimental result shows that the system can collect

analyze

transmit and store pressure signal in severe well environment of high temperature

high pressure and strong interference

and the system is designed reasonably and has advantages of strong anti-interference capability and applicability.
