Abstract

FIELD: drilling and overhauling of oil and gas oil wells. SUBSTANCE: installed on inclined journal of body 1 for rotation is mandrel 2. Outer surface of mandrel 2 is formed by conjugated to each other alternating parts of surface of ball 3 and side surfaces 4 of cylinders whose axes are located in plane square to axis of mandrel 2. After lowering of unit 9 into well 10 and its straightening with inner pressure of fluid nonstraightened corrugations remain over its edges. Device is screwed on drill pipes and run into well 10. In this case, mandrel owing to its streamline shape of working surface enters unit 9. During rotation of drill pipes, mandrel 2 straightness profiled unit 9 tightly rolling it to well 10. Built-up on walls of unit 9 and corrugation is higher specific pressure, friction is considerably reduced and decreased wear of walls of unit 9. EFFECT: increased speed and quality of expanding and simplified device manufacture process. 4 dwg
