METHOD OF BOREHOLE FIXING AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1996 - IPC

Abstract RU 2057905 C1

FIELD: borehole drilling. SUBSTANCE: this method of borehole fixing involves filling of hole clearance with nonhardening viscous-ductile grouting with required strength of structure which is determined by calculation. After exploitation is terminated casing pipes are removed out of borehole. Gear for implementation of method has two concentric pipes which are radially connected by means of metal bushings. Stoppers made of material readily soluble in acid are screwed into them. EFFECT: reliable separation of seams opened by borehole without decrease of their productivity factor. 2 cl, 3 dwg
