摘要
示烃成岩矿物是指与烃类活动具有成因关系的成岩矿物。通过综合利用地质、矿物岩石和地球化学方法,识别出了铁白云石、铁方解石、高岭石和黄铁矿4种示烃成岩矿物。对东营凹陷示烃成岩矿物在研究区不同层系中的分布和发育特征的分析结果表明,对示烃成岩矿物的研究可以在研究区流体输导体系中再现流体运动的过程及规律,分析其中控制物质演变和能量再分配的主导因素,揭示沉积盆地的油气生成、运移和成藏过程与成矿作用的对应关系,并对深部成岩作用以及油气运聚成藏在埋藏阶段的成岩响应进行评估。该研究成果对油气勘探开发具有较高的理论和应用价值。
Hydrocarbon-traced diagenetic minerals are the diagenetic minerals which have genetic relation with hydrocarbon activity.Four hydrocarbon-traced diagenetic minerals-ferro dolomite,ferrocal-cite,kaolinite and pyrite were recognized by synthetic application of geology,mineralogy and geochemistry methods.Distribution and development features of the hydrocarbon-traced diagenetic minerals during the course of hydrocarbon reservoir formation indicate that the research of the hydrocarbon-traced diagenetic minerals can reappear the fluid movement process and rule in fluid transportation system and find out the dominant factors of substance evolution and energy redistribution.It also can reveal the corresponding relationship between mineralization and hydrocarbon generation,migration,accumulation in depositional basin.To evaluate the diagenetic response of deep diagenesis and hydrocarbon reservoir forming at the burial phase has high value on theory and application for hydrocarbon exploration and production.
