pneumatic gravel drive system for drilling oil wells without liquid addition for offshore rigs and onshore rigs.

摘要

It consists of a gravel moving system that operates at high pressure, up to 5 bar on the pneumatic conveyor (2), and pulses of up to 7 bar on the flexible piping launched at 45º in the direction of gravel flow every two meters in the pipeline (1 ), which together with the optimization of the fluidization of the material inside the pneumatic conveyor (2) and the storage / transfer silos (3) allows the gravel transfer without addition of liquid and with high flow performance of the wells. drilling for pressure vessels, tugs and final disposal and similarly on the ground probe between the conveyor and the silos.
