Abstract:

For the high viscosity of the heavy oil，the high content of the non-hydrocarbon and asphaltic bitumen and the low saturated hydrocarbon and aromatic hydrocarbon，it is difficulty to identify the difference of each pay zone and the
well head heavy crude oil with chromatogram.By using reservoir bitumen of each layer and the well head heavy crude oil from certain multilayer heavy crude oil wells（Liaohe Oilfield）as experiment analysis samples，the samples are researched and analyzed by means of the fingerprint feature of gas chromatogram-mass spectra（GC-MS） of saturation hydrocarbon and the aromatic hydrocarbon.According to the technologies such as fingerprint correlation star picture，clustering analysis and factor analysis，the key pay zones of multilayer heavy oil wells are identified.Effect is obvious from actual enforcement result.This technology is applicable，costs less with short period，high accuracy and quickly putting into use，and there is the prospect of popularizing application.
