| 摘 要： | 月亮泡地区位于松南西部沉积体系斜坡背景下的三角洲前缘相带,受坡度、物源等因素影响,地层对比误差较大,沉积相认识不清楚,岩性圈闭难以落实。通过建立研究区高分辨率等时层序地层格架,重新分析区域的沉积演化模式,发现在青一二、青三层序时期地层内部发育多套上倾尖灭的地震反射轴。进一步研究证实,该地震反射轴反映松南月亮泡地区高台子油层发育了多期叠置的三角洲前缘沉积,即为本区的超覆圈闭发育区。应用三维地震识别技术刻画出岩性圈闭的展布形态和分布范围。高分辨率层序理论的应用在本区岩性油藏勘探中起到了重要的指导作用。 |

| Abstract: | Yueliangpao area is located in the delta front of western slope in southern Songliao Basin. Under the influence of slope and provenance, stratigraphic correlation, sedimentary facies recognition and lithologic trap exploration are hard to perform. By establishing high-resolution isochronous stratigraphic framework and re-analyzing regional sedimentary evolution model, several sets of updip pinchout seismic reflection axis are identified in the interior of Qing 1st and Qing 2nd sequence, and Qing 3rd sequence. Further research proved that these seismic reflections are responses of multiple-stage overlay delta front deposition of Gaotaizi oil reservoir in Yueliangpao area, where stratigraphic overlap trap are well developed. Therefore, the 3-D seismic technology can be used to describe the distribution form and range of lithologic trap. The theory of high-resolution sequence stratigraphy plays an important guiding part in the exploration of the lithologic oil reservoir in Yueliangpao area. |
