Basing on the introduction on the geologic characteristic of Xinzhan Oil and Gas Field, this paper discusses the oil and gas migration direction and reservoir continuity using reservoir geochemical data. It concludes that different sandstone zone in the same reservoir vertically in Heidimiao and Putaohua reservoirs are separated each other. The reservoir communication in a same fault block is nice arealy. The reservoir separation of different fault blocks is strong and the reservoir genesis is multi-stages and times. This conclusion has a conductive significance for the effective development of Xinzhan reservoir.%在简要介绍了新站油气田地质特征的基础上，应用油藏 地球化学参数探讨了油气运移方向及油藏的连通性，得出新站黑帝庙、葡萄花油气藏内部纵 向上同一油层不同砂岩组之间相互分隔；平面上同一断块油层连通性好、不同断块油层分隔 性强及油气藏成因具有多期次性的结论，这一结论对于新站油气藏的有效开发具有重要的指 导意义。
