摘　　要：利用有机地球化学方法中的氯仿“A”抽提、族组成、气相色谱、砂岩热解对储集层中的油气进行定量分析，判断油、气、水层，评价油层原油性质及估算产能，是一种有效的油藏地球化学评价方法。该方法可以大大提高油层解释的准确度，对油层定量评价，特别是在新盆地、新区块，对油气层的正确认识有很大的实用价值。With oil and gas in reservoir analysis quantitative used the method of extraction, compositional fractionation,gas chromatographic and sandstone pyrolysis, Recognition the oil, gas. Water layer of reservoir and crude oil property and calculate the productivity of the oil lager, It is a effective method of Reservoir geochemistry used this method can increase the accuray of oil layer interpretation and quantitiva assessment oil layer. Particular, It is a very worth of new basin and block with correct indentification oil and gas layer.
