摘要(Abstract)：
含油饱和度是评价储层流体性质及含油性的重要参数之一,含油饱和度的求取主要是靠地化热解值、孔隙度等参数。为进一步提高含油饱和度的精度,通过密闭取心资料建立含油饱和度的校正关系,使热解分析资料评价达到密闭取心评价水平。该方法的应用在探井及水淹评价解释中见到良好效果。
Oil saturation is one of the important parameters to evaluate fluid property and oil-bearing occurrence in a reservoir, which is mainly calculated by geochemical pyrolysis value, porosity and so on. In order to further improve the calculation accuracy of oil saturation, the correlation relation is established by way of pressure coring data and then makes pyrolysis analysis data reach the evaluating standard of pressure coring. The application of this method in evaluation and interpretation of exploration wells and watered layers has obtained relatively good results.
