    EXECUTIVE SUMMARY The occupational hazards to which workers are exposed in the well refurbishment drills are a major problem because they are the main cause of accidents in the oil industry, contributing to absenteeism, costly compensation and low productivity. The research carried out was based on the analysis of mechanical risk factors and their incidence in the generation of work accidents in oil well reconditioning drills. The assessment of mechanical risk factors was developed in the four processes of the well reconditioning drill in the company CCDC Rig 52, the identification was made through preventive observation cards and checklists; the measurement by means of the method of the Colombian Technical Guide (GTC 45) in which it is determined that there are unacceptable and acceptable risks with specific control; The mechanical risk factors detected as not acceptable in the process of operations were trapping and handcuffs with 41%, followed by falls at a different level with 37%. Out of a total of 71 work accidents, 59 are due to mechanical risk factors and the most affected are the Cuñeros with 19; Accident rates analyzed since 2013 show that in the last year 2017 the frequency index is 0.25 below the target set 0.8. Through the analysis carried out, it is determined that there is a positive association between the study variables in the calculation of relative risk (RR = 2.08), with a 95% confidence interval of 3.74 to 1.17. It is concluded that the mechanical risk factors generate accidents in high percentages during oil well reconditioning activities, so a prevention program is developed to reduce the frequency of undesired events.
