Design of pressure and temperature monitoring device while drilling in deepwater surface
Pressure and temperature monitoring device while drilling system used in deepwater surface drilling is an important tool to monitor pressure and temperature in drilling process.By adopting it,drilling engineer can realtime obtain engineering parameters of annulus pressure,drill pipe pressure and temperature,etc,and use it to learn and analyze state of downhole.Pressure and temperature monitoring while drilling system adopt ARM as core chip,and uses data acquisition and communication technologies to realize acquisition and transmission of pressure and temperature.The pressure and temperature measure while drilling system has advantages of small size,low power consumption,vibration resistance and high and low temperature resistance.The device has already been used in the first deep water well LW6-1-1 Pilot hole in the South China Sea.Its mechanical strength,stability,reliability in non-riser drilling conditions of deepwater is verified,measured data can truly reflect drilling operation.
