Abstract
Inventia se refera la un mecanism de ghidare si centrare a sevilor de foraj si centrare a tevilor de foraj din otel, de tip cu falci de prindere actionate hidraulic, dispuse ca organe principale de lucru, de doua falci de prindere si anume de o falca de prindere - conventional - denumita superioara si o falca de prindere - conventional - denumita inferioara, care sînt dispuse fata în fata în mod simetric, iar atunci cînd sînt închise, adica atunci cînd sînt aplicate între ele, la partea loor mijlocie se fala un spati circular, care are o forma aproximativ rotunda, acest spatiu circular fiind astfel profilat încît sa poata cuprinde, în bune conditiuni, dintr-o parte si din cealalta parte, teava de foraj.
