Two Way Communication Module Type2

The continuous wave pulser adopts a stacked valve structure, with a maximum opening and closing angle of ±12°, and is a motor with a maximum power of 630 W. The rotation controls the opening and closing of the stacked valve. The pulse of the mud is generated by the pulser valve plate. This valve plate is a device that limits the diameter of the mud flow channel. It uses data signals to control the motor to execute, thereby driving the valve plate to run and generate pressure pulses.

Downhole data is converted to form a pressure pulse wave, and the pressure pulses propagate upwards in the well along the drilling tool, thereby transmitting the data to the ground.

The valve plate of the pulser is driven by a three-phase motor, and the valve plate is rotating.

Product Details

Product Features:

1. Using high-frequency pulses from 0 to 40 Hz to generate continuous signals, the rate will be greatly improved, and the maximum pulse width can reach 40 bps.

2. The maximum power is 630 W, the opening and closing of the direct drive control stack valve can provide a maximum torque of 15 Nm, and hydraulic oil is injected into the interior to play a role in lubrication and cooling.

3. The rotator uses 5 opposing poles to provide higher accuracy and resolution.

Product parameters:

-Rotation torque: 4-15Nm

-Voltage withstand: 25000PSI

-Temperature resistance: 150℃

-Maximum angle: ±12° (mechanical limit ±15°)

-Maximum power consumption: 630W (90V@7A)

-Valve plate gap: 1.5-2.3mm

Shortcoming:

The stacked valve valve plate-type structure has relatively high requirements for working conditions.
