本文应用甾烷、萜烷地球化学参数,研究了生油母质类型、有机质成熟度、油源对比及烃类相对运移等问题,并提出对二连盆地石油勘探的一些建议。 In this paper, the geochemical parameters of sterane and terpane were used to study the types of parent material, the maturity of organic matter, the contrast of oil source and the relative migration of hydrocarbons. Some suggestions on oil exploration in Erlian Basin were also proposed.
