Abstract

Inventia se refera la instalatiile de forare si poate fi utilizata pentru forarea sondelor de adancime mare. Sistemul de foraj antrenat de fluid pentru forarea sondelor de adancime mare include o carcasa (1) in care sunt amplasate o turbina (2), un reductor precesional (3) si o scula de forare (4).Turbina (2) contine un stator (5), o camera suplimentara (10) si o roata motoare (8) fixata rigid pe arborele de intrare (15) cu flansa inclinata (16) a reductorului precesional (3). Reductorul precesional (3) mai include un bloc - satelit (18) executat din doua parti legate intre ele prin intermediul unor craboti, intre care este amplasat un element elastic, rotile centrale: una (26) legata rigid cu carcasa (1) si, respectiv, a doua (27) legata cu carcasa (1) prin intermediul crabotilor si elementului elastic. Blocul-satelit (18) este legat cu arborele de iesire (31) prin intermediul unui cuplaj cu bile (32).
