Background

The measurement while drilling technology developed vigorously in recent years has great effects on enhancing the geosteering and stratum evaluation capabilities of extended reach wells, high-difficulty horizontal wells and branch wells, improving the oil layer drilling rate and the like. However, as the amount of downhole information is continuously increased, the high-speed data signal transmission becomes more and more prominent in the design of measurement-while-drilling systems, and becomes a problem that measurement-while-drilling technology must face in the continuous forward development.

In the current underground telemetering signal data transmission technology, mud pulse transmission, especially continuous wave mud pulse transmission, is a data transmission mode which is the most widely used and has great development potential due to high transmission rate and strong anti-interference capability. The mud pulse continuous wave generator generates continuous pressure wave signals by changing the relative position of the flow cross section of the rotating rotor and the stator, and the generation mode comprises a rotating valve and a shearing valve. The continuous wave generator comprises a continuous wave pulse generating unit, a power output device and a necessary pressure balancing and sealing module. The continuous wave pulse generating unit (namely a stator and rotor structure) and the power output device (comprising a speed reducer and a direct current motor) are respectively positioned in the slurry flow and the lubricating oil, and the continuous wave pulse generating unit and the power output device are interconnected through a transmission shaft rotating at a high speed.
