摘要

针对准噶尔盆地玛湖凹陷百口泉组地层不整合油气藏成藏主控因素不明确等问题,运用石油地质学理论技术与概率论方法,系统分析该油气藏内幕结构,识别并量化了主要地质影响因素,总结出一套完善的定量评价技术。研究表明:在玛湖凹陷古地貌环境和特有的沉积体系作用下,生烃处形成碱性环境,藻类生物众多,烃源岩有机质含量丰富,转化率高,生烃潜力大,伴随着大范围分布的非均质致密砂岩,使玛湖凹陷具有稳定的烃源条件和良好的储集环境。同时,不整合-断裂的组合体系使得油气从烃源层逸出后,可以沿断层完整地进入储层并有效地保存下来。该研究为玛湖凹陷后续油气藏定量评价提供了重要评判依据,大幅提升精准度,对后续勘探具有较好的指导意义。

Abstract

To clarify the main controlling factors for formation of stratigraphic-unconformity hydrocarbon traps in the Baikouquan Formation of the Mahu Sag in the Junggar Basin,petroleum geology theory and probabilistic methods were applied to systematically analyze the reservoir architecture,identify and quantify the primary geological influencing factors,and a set of comprehensive quantitative evaluation methods were formulated.The results showed that,under the Mahu Sag's paleo-geomorphology and characteristic sedimentary system,the hydrocarbon generation areas were alkaline with abundant algal organisms; the source rocks were rich in organic matter with high conversion rates and great hydrocarbon-generation potential;and these were accompanied by extensively distributed heterogeneous tight sandstones.This combination provided the Mahu Sag with stable source conditions and favorable reservoir settings.Moreover,the combined unconformity-fault system allowed hydrocarbons to escape from source layers and migrate along faults into reservoirs with integrity and effective retention.Thestudy offers a critical basis for quantitative evaluation of reservoirs in the Mahu Sag,significantly improving accuracy and providing valuable guidance for further exploration.

Key words： stratigraphic trap; trap effectiveness; Baikouquan Formation; Mahu Sag; quantitative evaluation
