Auto colonies in deep drilling. Yunin E.K.

This book is devoted to the problems associated with the mechanisms of the occurrence of the Auto -Coil of the Doloto - Bulge Column in the process of drilling deep wells. The appropriate mathematical models have been developed and analyzed, describing the behavior of the drill column as a mechanical system with distributed parameters with non -unique connections imposed on it, which made it possible to determine the conditions for the occurrence of steep and longitudinal car lines, as well as the longitudinal resonance of the tool during the drilling process of the well. Measures are proposed to prevent these phenomena without the use of any additional devices, and the algorithm for working out the generating tool is presented, which allows the most efficient use of the energy supplied to the fate to deepen it. Possible solutions to the problems that arise when using the dependencies of depressing the face on the regime parameters in order to predict and optimize the drilling process.

The book is primarily intended for those who decided to devote themselves to research work-students and graduate students, as well as teachers, engineering and technical workers and everyone who is interested in the tasks of drilling mechanics of deep wells.
