Intelligent Flow Controlling Apparatus For Oil Field Waterflooding

The thesis studies intelligent flow controlling apparatus for oil field waterflooding in a d- eepgoing way. Its research findings has changed traditional process engineering, which must waterflood for only a layer from bottom layer to up one , and flows of several layer in a well can be controlled and adjusted at the same time now. The technology raises efficiency and precision of waterflooding greatly and overcome a difficulty of layer disturbance. The design is made up of synchronous detecting and adjusting apparatus and control system.Control system detects flow, pressure and temperature of waterflooding, and pressure of earth layer automatically, then microprocessor calculates with PID formula ,makes a result,and controls opening of the stopper which is at bridge eccentric water distributor through regulat- ory agency, so the flow of every layer in a well is configured accurately according to its set value.
