| 摘 要： | 胡庆油田湖相原油成熟度低，多为低成熟原油，生物降解作用轻微，原油中含有丰富的咔唑类化合物。分析表明，原油成熟度对咔唑类化合物含量及相对组分影响明显，源岩沉积环境对其也有一定的影响，而生物降解作用对咔唑类化合物含量及相对组分影响很小。原油中咔唑类化合物含量、链基咔唑/苯并咔唑及苯并咔唑比值受原油成熟度与沉积环境影响明显，已不适合用来指示油气运移距离，而二甲基咔唑同分异构体比值所受影响小，仍可作为油气运移的有效参数。

| Abstract: | The maturity of lacustrine oils in Huqing oilfield is low,and the role of biodegradation is poor.Rich carbazole compounds,including carbazole,alkylcarbazole and benzocarbazoles were detected by GC/MS in lacustrine oils from Huqing oilfield.The results indicate the maturity plays an important role on the concentration of carbazole compounds and its relative contents,and the biodegradation plays weak role on the carbazole compounds.The concentration of carbazole compounds,the ratio of alkylcarbazole/benzocarbazole and the benzocarbazole ratio are not suitable to be the indicator of the oil migration,which are mainly controlledby the maturity of lacustrine oils,and the isomer ratio of dimethycarbazole is still a good parameter of the oil migration. |
