The thesis is dedicated to a solution of loading influencing problems on corrosion fatigue damage accumulation of downhole equipment mobile members (DEMM) with the purpose for effective methods development of their durability and residual life evaluation. The experimental researches of DEMM operation loading and local stresses of a flexure in members of drill columns and sucker rod string on curved leases are held. The method of DEMM fatigue damages summation at a broadband loading and applicable method of stochastic loading process schematization are designed. A method of the high level skew stresses registration and four parametric equation of a fatigue curve for the corrosive factor registration are designed at an estimation of DEMM durability Experiment-calculated methods of DEMM loading estimation with the help of loading indicator both DEMM loading and residual life estimation by results of studies at full scale model with miscellaneous stored corrosion fatigue damage are improved. Findings of investigation are approved experimentally on DEMM full scale samples.
