摘　　要：安棚深层系储层具有孔低渗特性,录井表现为显示多、级别低的特征,流体性质表现为油质轻、易挥发的特征。通过对该区录井显示特征进行深入分析,提出了在该地区能较好评价储层流体性质的参数,制定了详细的评分原则。结合储层物性参数,利用多参数量化后的得分值,建立了多参数综合评价图版。Reservoirs in deep of Anpeng oilfield have low porosity and low permeability. There are many hydrocarbon shows in logs but iheir grades are low, and hydrocarbons are light and evaporable. Parameters that can be used to evaluate reservoir fluid properties are presented based on insights of logging characteristics and the detail grading principles are determined A multi - parameter integrated evaluation chart is built by using the value of multi - parameter quantification and in combination with reservoir physical property parameters.
