THREE DIMENTIONAL FLUORESCENT FINGERPRINT TECHNIQUE AND ITS APPLICATION TO PETROLEUM EXPLORATION

Studying the three dimentional fingerprint analysing technique,the author proposes the similiarity indexes T1(Ex228nm/Em340nm)and the differential indexes(S,α,K,F,R)for the three dimentional fingerprint graph of crude oil and related samples,and the finger graph is divided into four types i.e.O,B,Q,R.These nidexes are favourable to differentiating fluorescent abnormalities,providing solid basis for correlations of oil /oil,oil/source rock,and application to surface chemical exploration,etc.
