75GF Vertical Drilling Tool Generator

Vertical Drilling System Tool The generator is an auxiliary device for underground drilling equipment and is dedicated to oil production equipment for power supply. As downhole power is limited, the transmitter is either powered by a downhole generator or battery powered. However, battery power is short and expensive. Therefore, the power supply by the downhole generator is used to provide a reliable power source with long life, high temperature and high pressure for the downhole, and the well inclination, azimuth, tool face angle and formation parameters measured by the probe sensor are sent to the ground in real time by electromagnetic waves. The ground system collects data and displays it to the in-situ engineer after processing.

1. Principle of structure

The whole system is a downhole instrument used in oil drilling, which is resistant to high temperature, high pressure and sealing. The system is divided into two parts, part A rotating is called dynamic drill pipe, part B not rotating is called fixed jacket. The instrument is powered by 2 generators and 2 generators are put
together. The permanent magnet rotor (hollow) of the generator is outside the moving drill rod, and the stator is in the fixed jacket. When the dynamic drill rod rotates, the stator generates an induced electromotive force, and the generated electric energy is filtered and stored and supplied to the circuit under the whole system. The stator (hollow) of the upper generator is outside the moving drill rod, and the rotor is in the fixed outer casing. When the dynamic drill rod rotates, the
stator generates an induced electromotive force, and the generated electric energy is supplied to the upper circuit electric energy.
