1.GET-BMWD
Overview
The GET-BMWD system relies on underground lithium batteries to provide electrical energy, real-time measurement of underground engineering parameters, pulse coding of the measured parameters, and control the opening and closing of the pulse generator solenoid valve through a driver to achieve small valve driving large valve, controlling the change of mud flow in the drill pipe to generate pulse signals. The surface pressure sensor receives the signal, which is filtered and decoded on the surface, and provides the data to the drilling engineer as the basis for directional drilling control.

● Transmission method of positive pulse generator
● Underground battery power supply
● Easy assembly and maintenance at the well site
Low cost of instrument maintenance and upkeep
● Multiple wellbore sizes
2.GET-PMWD
Overview
The GET-PMWD system relies on the power supply of the well turbine generator to measure the downhole engineering parameters in real time. The measured parameters are pulse encoded, and the opening and closing of the control valve are controlled by the driver to achieve small valve pushing large valve and control the change of mud flow in the drill pipe to generate pulse signals. The surface pressure sensor receives the signal, which is filtered and decoded on the surface, and provides the data to the drilling engineer as the basis for directional drilling control.

feature
● Positive pulse transmission method
Power supply of high-power turbine generator underground
● Compatible with similar foreign instruments
● Multiple wellbore sizes
● High transmission speed
● Can be connected to different types of geological parameter sensors
3.GET-SLWD
Overview
The GET-SLWD system relies on underground generators to provide power, and the generator rotor is coupled with the inner shaft to generate electrical energy to supply power to the directional probe tube; Directional probe for measurement and control of pulse generator operation status; The upper end is a hydraulic pump that provides driving force for the pulse generator. The mud flows in the annular space formed between the fish neck assembly and the flow limiting ring and the mushroom head. When a signal is transmitted, the mushroom head rises and pauses before resetting. When the mushroom head elongates for a short time, a positive pressure pulse is generated; The ground equipment collects the mud pulse information detected by the pressure sensor from underground, and transmits it to the ground data processing system for processing and decoding, as the basis for directional drilling control.
