Rotary drill system with liquid drive for drilling wells of great depth

摘要

the invention relates to the drilling and can be used for drilling wells from the deep sea. the drilling fluid for drilling wells from trained big depth includes a casing (1) in which are located a turbine (2), a reducer (3) and a precesional drilling tool (4).the turbine (2) has a stator (5), an extra room (10) and a drive wheel (8) fixed rigidly on the input (15) with the flange (16) reductorului precesional incline (3).precesional reducer (3) includes a satellite (18) executed block of two parts connected by means of craboti, between which is positioned an elastic element, the central wheels: one (26) connected rigidly with the housing (1) and, respectively, second (27) connected to the housing (1) by means crabotilor and elastic element.satellite block (18) is connected with the outlet (31) via a coupling with balls (32).
