Bits for Low Speed Drilling

Commissioned by the All-Union Research Institute of Organization, Management and Economics of the Oil and Gas Industry (VNIIOENG). Part one. Krasnodar Territory, Kudako River Valley, Kievskoye village, obelisk stylized as an oil rig, the inscription “THE FIRST WELL IN RUSSIA DRILLED BY COLONEL NOVOSILTSEV ON THE KUDAKO RIVER IN 1864”. Oil wells - panorama. The work of one of the oil wells. Cr.pl. - panoramic view of roller cone bits. Drillers at work. The casing string is lowered into the well. Bit type for working at a depth of more than 200 meters. View of one of the workshops of the Kuibyshevburmash association. Worker at the "HEYLIGENSTAEDT" machine. The process of making cones. Types of cutters - cr.pl. Chisels with inserted carbide teeth with a different shape of the working head, r.pl. - milled trapezoidal teeth. Cr.pl. - taper-shaped carbide teeth. Chisels in operation at the test bench - start of drilling in a monolithic block of granite. The arrow shows the load on the bit with carbide teeth. Three series of bits for low-speed drilling: GEN, GNU, GAU - kr.pl. Chisel type, consisting of three sections. Part two. Work in the workshop - welding of finished sections, cutters, cutting of the connecting thread. Low-speed drilling bits on a conveyor belt. Water jet flushing is in progress. Installation of replaceable carbide nozzles in the exit to the bit hole. Chisel in operation - water jet at a speed of 120 m / s. blurs soft rocks. Injection of lubricant into the bit system, installation of a metal cup, diaphragm, cover, fastening of the retaining ring. General view of the bits of the GNU, GAU series. The rubber ring is a feature of the GAU series bits (the GAU drill bit works at the bottomhole for up to 150 hours). The chisels move along the conveyor in the workshop. Lesson of drillers in the classroom - studying the "Basic rules for the operation of roller-cone bits with sealed oil-filled bearings when drilling oil and gas wells", the teacher draws a diagram on the board. Practical lesson on the use of new bits in the well. Briefing before starting work. The drilling rig is working. Cr.pl. - the master manually turns the chisel, secures it with a machine key. Revision of the winch before drilling. Control measurements of the length and curvature of drill pipes, adjustment of the pump, compressor. Control of the amount of abrasive particles - sand in the solution. Summer, a train with cisterns travels by rail. Oil storage panorama. Cars go along one of the central streets of Kuibyshev (present-day Samara), Volga cars - a taxi, a trolleybus - go. The Ryleev heat ship sails along the Volga. The plane is flying.
