    Abstract
  • Different influence factors have different influence degree to the different components of geo-chemical pyrolysis degradation. In this paper, the correction models of light, middle and heavy components ard sample weight, porosity and volume were established from the view point of influence mechanism. After correcting geochemical pyrolysis degradation data and getting accurate residual hydrocarbon content and gross hydrocarbon quantity, the evaluation models of oil saturability were built. A set of perfected methods to correct data, obtain oil density and residual hydrocarbon content and evaluate oil saturability were formed. The oil saturability of 32 layers in 21 wells with different reservoirs, levels and oil properties was evaluated. The results were very close to those from sealed core analysis.
