Key words: well drilling, measurement while drilling, commutator, fluidic devices, sensor.
The use of fluidic devices for the development of the well bottom telemetry equipment is offered. Fluidic devices have a high reliability, a simple construction and a small size. The assembly of the fluidic commutator for the well bottom telemetry system is given. The fluidic logical elements such “AND”, “OR” and “NOT” are taken as a basis of the commutator. The offered device allows realizing the camp-on switching of four well bottom sensors.
