Abstract: Skin factor is the most important parameter that diagnoses and identifies formation damage, and also reflects loss of oil well production. According to well testing assumption, the paper suggests skin factor from well testing that will be recollected and annualized, also give out calculation formulation. By examples,quantitative evaluation of formation damage is very good. It is
feasible method that is evaluation of formation damage in drilling, completion and stimulation.

Key words: reservoir evaluation, skin factor, quantitative analysis
