Abstract :
Through analyzing experimental data in oilfield, threshold temperature and pressure of lowered temperature and gathering-transportation technology were determined in Daqing Putaohua Oilfield, and then a set of control software was compiled in order to realize auto-optimizing control of gathering parameters in pipes. A reasonable range of wellhead back pressure was from l.OMPa to 1.5 MPa in Putaohua oilfield. Threshold temperature was around 27°C when water cut was from 40% to 70%. But when water cut was more than 70%, the threshold temperature can be reduced to around 25°C.
