塔里木盆地顺北地区近期油气勘探取得重大进展，但深部流体活动下，该地区的原油成因机理相对复杂。深部流体输入的多种元素可促进藻类等生物的繁育，提高盆地生产力，但主要生物类型及主控因素研究薄弱；烃源岩受深部流体影响再活化生烃的主控因素是热效应还是物质作用，机理不明，产物识别研究极少。本项目以塔里木盆地烃源岩为对象，利用地质学方法，识别深部流体活动影响的层段；利用古生物学方法，厘清特定的成烃生物及组合，提出深部流体促进优质烃源岩发育的机理；自主研发的反应釜，解决了黄金管产物少、不锈钢釜惰性不足、加入的流体物质定量难等问题，用以开展富CO2与富H流体再活化烃源岩生烃的模拟实验；利用有机地化分析，厘清深部流体影响烃源岩生烃的机理；通过FT-ICR-MS等技术，分析产物中的萘等芳烃，建立产物的识别方法。开展顺北地区油源对比。本研究将完善经典石油地质学的生烃机理，指导油气勘探实践，具有理论与应用的双重意义

There was giant breakthrough of hydrocarbon exploration in Shunbei Area, Tarim Basin nowadays, but the mechanism of hydrocarbon generation was much more complicated due to the deep-derived activity in this area. The deep-derived fluid can improve the basin’s productivity by inputing various elements, which will fertilize the organism, such as alga, but the most favorite organism and its main controlling factor are still unclear. The main reactivation controlling factor, thermal or material effect, for source rock to generate hydrocarbon needs to be unrevealed, and the research about identification material for such reaction was very rare. Taking source rock in Tarim Basin as example, the project will identify the right source rock sector which was obviously affected by deep-derived fluid by means of geology method. And the special organisms and their combination will also be specialized by means of paleontology, meanwhile, the mechanism of deep-derived fluid promoting excellent source rock development will be proposed. The stable and large space reactor vessel, which was invented to resolve the problem of limited space for golden vessel while unstable for steal vessel, will be used to carry out the experiments for reactivation of high-maturity organic source with CO2-riched and H-riched deep-derived fluid in precise volume. The secret of how deep-derived fluid affect hydrocarbon generation will be answered by means of geochemical analysis. The aromatic matters, especially naphthalene, will be analyzed by FT-ICR-MS in order to identify the specialized matters for recognizing such production. The oil-source correlation will be done in Shunbei Area. The project will consummate the hydrocarbon generation theory in classical petroleum and natural gas geology, and be useful for hydrocarbon exploration practice.
