【摘要】 胡庆油田烃源岩主要分布于斜坡带的沙三段和柳屯-海通集洼陷的沙一段、沙三段。通过对有机物类型和丰度、生物标志化合物及热演化与成熟度的研究表明,烃源岩具有低Pr/Ph值(<1)、较高(-蜡烷含量、高甾烷C27/(C28+C29)比值、水生浮游动植物生源发育等特点,表明形成于咸化、还原性强的沉积环境,烃源岩可分为低成熟-未成熟、过成熟、过成熟-成熟三种类型。更多还原

【Abstract】 Hydrocarbon resource rocks of Huqing oil field mainly exist in the member of Es₃ in the slope and of Es₁ and Es₃ in Liutun-Haitongji subsag. According to the study of types and abundance of organic, biomarkers and thermal evolution, the character are: low data of Pr/Ph（<1）, relative great content of γ-gammacerane, upper ratio of C₂₇/(C₂₈+C₂₉) and growth of aquicolous pelagic animals and plants. These show that hydrocarbon resource rocks come into being in salt and reductive environment. Hydrocarbon resource rocks can be divided into three types: low mature-immature, over mature and over mature-mature.更多还原
