通过数理统计、典型解剖,结合模拟实验,对济阳坳陷页岩油富集要素进行深入剖析,认为济阳坳陷页岩油富集要素主要包括岩相、可动性、微裂缝和压力,其中富有机质纹层状岩相是页岩油富集的基础,可动性是页岩油有利产出的先决条件,微裂缝是页岩油富集产出的关键,异常高压是页岩油富集产出的重要条件;依据出油井段页岩油富集要素演化及组合规律,结合页岩油富集产出特征,建立了陆相断陷湖盆页岩油有机网络-微裂缝体系富集模式,主要包括生烃增压、应力调整和油气富集3个阶段,认为页岩油在生烃高压驱动下沿着有机网络体系和微裂缝网络体系向高压区中的相对低压区富集,预示着成熟度较高微裂缝发育的优质烃源岩才可能具有产能,页岩油主要富集在有效烃源岩初次运移通道附近,暗示着非常规页岩油气与常规油气富集过程的统一性;该成果为研究区下一步页岩油井位的部署提供了理论依据。 Through mathematical statistics, typical anatomy and simulation experiments, the enrichment factors of shale oil in Jiyang Depression are analyzed in depth. The factors that enrich the shale oil in Jiyang Depression mainly include lithofacies, mobility, micro-cracks and pressure , Of which organic-rich laminar facies is the basis of shale oil enrichment. Mobility is the prerequisite for the favorable output of shale oil. Microfissure is the key to the enrichment of shale oil. The abnormal high pressure is shale According to the evolution and combination rule of shale oil enrichment elements in oil well section and the characteristics of shale oil enrichment and output, the organic network of shale oil in continental rift lake basin was established, namely microcrack The system enrichment model mainly includes three stages: hydrocarbon generation and pressure increase, stress adjustment and oil and gas accumulation. It is believed that shale oil, driven by high hydrocarbon generation pressure, moves along the organic network system and microcrack network system to the relatively low pressure area Enrichment indicates that high-quality source rocks with high mature micro-fissures may have productivity. Shale oil is mainly concentrated near the primary migration channel of effective source rocks, suggesting that unconventional shale oil and conventional oil and gas rich Set the process of unity; the results for the study Next shale oil well site deployment provides a theoretical basis.
