摘要
通过对江汉盆地几口井的储油岩进行热解分析,快速地判断了原油性质并估算了原油的密度;准确预测了储油岩孔隙度和含油饱和度;成功地进行了储层性质判断和含油级别划分。储层综合评价表明,用热解法判断储层性质比测井或试油方法能更精细地描述储层的性质,并具有需用样品量少、分析周期短、成本低等特点,该技术可成功应用于储层评价。
Based on the pyrolysis analysis of reservoir rocks from several wells in Jianghan basin, we assessed the quality and density of crude oils, accurately predicted the porosity and oil saturation of the reservoir rocks, and suecessfully classified reservoir properties and the grades of oil - bearing reservoirs.Comprehensive reservoir assessment shows that pyrolysis technology is more superior than logging or oil testing in identifying reservoir property, which needs less samples, short analysis period, low cost,and delivers report in a rapid manner. Therefore, this technology can be used widely in reservoir assessment.
