PROPERTIES AND GEOLOGICAL MEANINGS OF RESERVOIR ROCK-EVAL PYROLYSIS PARAMETERS OF ZAO-Ⅴ OIL SUB-FORMATION IN SHENJIAPU oil field

摘要: 该文详细阐述了储层热解参数的地球化学含义及地质意义,并结合沈家铺地区储层热解参数特征,分析了沈家铺地区原油的性质和纵向上储层含油性的变化,指出了枣V油组的主力油层,检验了射孔的有效性,提出了补射层段。分析结果表明,沈家铺地区原油密度高、粘度大,属重质稠油 ;纵向上随深度增加储层含油性逐渐变差,由油层—油水同层—水层。

Abstract: The geochemical implications and geological meanings of reservoir Rock-Eval pyrolysis parameters were discussed in details in the paper,and combined with the properties of reservoir Rock-Eval pyrolysis parameters in Zao-Ⅴ oil sub-formation in Shenjiapu oil field,the crude oil properties and vertical oil saturation of reser-voirs were analyzed,the main oil layers were pointed out,the effectiveness of the perforations were checked,and sand layers requested for being perforated were put forward in order to raise the production.The results showed that the crude oil had high density and viscosity,and reservoir oil saturation became worse vertically,i.e.,from oil alyers to oil-water layers till pure water layers with increase of depth.
