Absolute quantification of biomarkers shows that the bitumen contents of source rocks and waxy hydrocarbon contents of crude oils in this area increase with increasing maturity indicating that thermal maturity is one of the major factors controlling the formation of highly waxy oils in this area .

生物标志物定量分析结果表明，区内烃源岩沥青与原油中的 蜡质 烃含量随成熟度增加而增加，反映热成熟度是控制该区高蜡油形成的重要因素之一。

The waxy oil . Almost all effective depressants contain long hydrocarbon chain and polar polymer .

有效的降 凝剂基本都具有长 烃链和极性基的聚合物。
