| 摘 要： | 对辽河油田原油、有机质的Pb ,Sr,Nd同位素进行了研究。原油、有机质的Pb ,Sr ,Nd同位素资料和分析表明 :在辽河油田 ,仅有极少部分原油与老第三系有机质热解有关 ,大部分原油为地幔流体与古生界、震旦系海相碳酸盐岩壳幔相互作用而生成 ,另一大部分则为地幔流体的CO ,CO2 与H2 的费托合成反应生成。油源对比表明 :老第三纪以下的古生代前陆盆地有更大的油气前景。

| Abstract: | Pb,Sr,Nd isotopes of the crude oil and organic matter of Liaohe oilfield are studied. Pb,Sr isotopic data of crude oil and organic matter show that in the Liaohe oilfield, only a little of crude oil is related to organic matter, most of crude oil is generated by crust mantle interaction between mantle fluids and Palaeozoic and Sinian marine carbonate rocks, the other major crude oil is formed by Fischer Tropsch synthesis of mantle fluids. Oil source correlation shows that Palaeozoic foreland underneath the Lower Tertiary depression has much better prospect for petroleum exploration. |
