| 摘 要： | 对金羊盆地SZK01井岩芯的详细观察、系统取样及有机地球化学测试分析,研究该井下侏罗统北票组的沉积相类型及其有机质特征。在该井岩芯中主要识别出湖泊相沉积,自下而上可进一步识别为滨浅湖-半深湖-滨浅湖沉积,说明金羊盆地在北票组沉积时期沉积水体经历过一个由浅变深、再由深变浅的阶段。SZK01井北票组烃源岩总体属于差-中等级别,有机质丰度主体上呈现出自下而上先增加后减少的趋势;有机质类型主要为Ⅲ型和Ⅱ2型,即有机质主要来源于陆源有机质输入;有机质热演化处于高成熟-过成熟阶段。

| Abstract: | Based on the detailed observations，systematic samplings，organic geochemical analysis of the core of Well SZK01 in Jinyang Basin，the types of sedimentary facies and organic characteristics of Lower Jurassic Beipiao Formation of the well were studied． The lacustrine facies was the main sedimentary facies identified in Well SZK01，and showed the changeable process from shore- shallow to semi- deep then to shore- shallow lake sedimentary subfacies in ascending order． The change trend revealed that the sedimentary water body went through a stage from shallow to deep in depth，and then from deep to shallow later during the Beipiao Formation stage in Jinyang Basin． The hydrocarbon source rocks of Beipiao Formation in Well SZK01 were mainly ranked on poor- medium level，and its organic abundance increased firstly and then decreased from the bottom up，in general． The types of the organic matter were mainly Ⅲ- type and Ⅱ 2 - type， which were mainly based on terrestrial organic matter input． The thermal evolution of the organic matter was in high- over maturation stage． |
