DEEP ORIGIN AND EXPLORATION FOR THE HYDROCARBON OF THE LUNAN SALIENT ON THE HINTERLAND OF THE JUNGGAR BASIN
-
摘要: 准噶尔盆地腹部陆南凸起油气具有高成熟度、低硫、高氮、碳同位素较重等地球化学特征;综合各项资料认为,这类油气的形成与具火山物质的深部烃源有关;生物标志物的指纹特征表明,石炭系泥岩抽提物与原油具有良好的亲缘性.在此认识基础上,作者对该区油气勘探提出几点建议.Abstract: The hydrocarbon of the Lunan Salient on the hinterland of the Junggar Basin has the geochemical characteristics of high maturity,low sulfur and high nitrogen contents,heavier carbon isotope,etc.By synthesizing various data,it is considered that the formation of this kind of hydrocarbon should be related to the deep hydrocarbon resources with volcanic material.Tte fingerprinting characteristics of biomarkers show that the Carboniferous mudstone extracts have good affinity to crude oil.Based on such cognition,some suggestions for the hydrocarbon exploration of the area are put forward by the authors.
