In first, magnetic flowmeter is between top connection and pin body, and in first, magnetic flowmeter is threaded with connector;
In second, magnetic flowmeter is between lower outside housing and lower cable body fittings body, and in second, magnetic flowmeter is threaded with lower outside housing.
One, the present invention drives screw turns by motor, leading screw band movable valve plug is continuous moving in upper shell body and lower outside housing, due to the motion of spool, taphole pressure is changed, the pressure of liquid feeding end is surveyed by inlet pressure sensor, the pressure of taphole is measured by outlet pressure sensor, data transmission is carried out again by circuit board, control motor in time finally by aboveground data processing and adjust mouth pressure to adjust injection rate, realize accurately injecting, thus realize the continuous adjustment of injection rate.The present invention has good sealing to arrange, and can ensure that the place such as motor, circuit board does not have solution to enter, good sealing effect, motor and circuit can normally be worked.
Two, employing docking charging modes of the present invention, avoids wiring and the sealing system of complexity when adopting cable energy supply, reduces cost, saved space, achieve the charging of down-hole power.There are the following problems for traditional power supply mode originally: difficulty of going into the well is large, and the easy loss of equipment, this dock charging technique also meets the needs of physical device.
Three, the present invention also adopts wireless transmission method to realize communicating with aboveground, more convenient than cable transmission mode feasible.Because subsurface environment is complicated, traditional approach easily receives interference, and cannot accomplish high-pressure situations lower seal, and that is, traditional approach can not adopt wireless transmission method, and the present invention is miniaturization more, anti-high pressure, and the stability that improve transmission means.And this wireless transmission method did not appear at oilfield in the past.The present invention is used for polymer injection and recovers the oil.
