摘　　要：利用前人对哈得逊油田调整过程的认识及相应的地质图件,并在更为广泛的范围内对研究区自二叠纪以来的流体势演化进行了分析,建立起油藏调整地质模型,对古油藏原油调整过程进行了模拟分析。结果表明:研究区确实存在从乡3井古油藏向目前哈得逊油田构造高点进行调整和重新成藏的条件。白垩纪末,乡3井古油藏的原油向南东方向调整,调整形成以S108井为中心的古油藏;之后,原油持续向南调整,到上新世早期形成以哈得113为中心的古哈得逊油藏,并在上新世期间基本保持稳定;第四纪以来,哈得逊油田发生了明显的调整,在约1 Ma的时间内调整到目前的范围。Based on the previous understanding of the adjustment process of Hudson oilfield and the corresponding geological map, the evolution of fluid potential in the study area since the Permian was analyzed in a wider range, the geological model of reservoir adjustment was established, and the adjustment process of crude oil in the ancient reservoir was simulated and analyzed. The results showed that there were indeed conditions for adjustment and reservoiring from the paleo reservoir of Xiang3 well to the structural high point of Hudson oilfield. At the end of Cretaceous, the crude oil of Xiang3 well old reservoir was adjusted to the southeast, forming the old reservoir with S108 well as the center;after that, the crude oil continued to adjust to the south, forming the old Hudson reservoir with Hude113 as the center in the early Pliocene, and basically remained stable during the Pliocene;since the Quaternary, Hudson oilfield has been significantly adjusted, and adjusted to current scope.
