摘　　要：各种不同影响因素对地化热解资料不同组分的影响程度不同。该文从影响机理入手,分别建立了地化热解资料的样品重量、孔隙与体积及轻、中及重质不同组分的校正模型。对不同来源地化热解资料校正之后,在准确求取残余烃含量和含油气总量的基础上,建立了含油饱和度评价模型,并形成了一套较为完善的资料校正、原油密度和残余烃含量求取及含油饱和度评价的方法。对不同储层、层位、原油性质的21口井共32层的含油饱和度进行了评价,评价结果与密闭取心井的岩心分析结果非常接近。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 metho- ds 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.
