| 摘 要： | 根据测井、地震、岩心等资料，以胜利油田滩海地区馆下段为例，对不同区块同生断层进行研究，发现其断层两盘的沉积差异，跟同生断层的活动强度与沉积物的供给速率有关，且断层走向与河流主流线的关系，对沉积差异也存在较大影响.在深入研究的基础上，总结了两种情况断层控砂的模式图，具体表现为：断层垂直流向时，上升盘可容空间小，砂岩相互切割叠置严重，以大套块砂为主，泥岩难以保存，砂岩百分含量高；下降盘砂岩多呈孤立状，单层砂岩较厚，但泥岩相对更发育，故砂岩百分含量低.当断层走向平行于流向时，上升盘砂岩少且薄，砂岩百分含量低；下降盘砂岩厚且多，砂岩百分含量高.该断层控砂模式对于在高含砂岩地区找油，特别是寻找隐蔽油气藏具有理论指导意义.

| Abstract: | Taking the Lower Member of Guantao Formation in Tanhai area, Shengli Oilfield for example, the syn-sedimentary faults in different blocks are studied according to the logging, seismic and core data. It is found that the sedimentary differences between the two walls of faults are related to the active intensity of syn-sedimentary faults and supply rate of sediments, and the relationship between fault strike and river mainstream direction as well. Based on further research, two cases of sandbody controlling model are summarized as follows:When the fault is perpendicular to flow direction, due to small space in upthrown side, the sandstone is cut and overlaid, dominated with large blocks of sand. The mudstone is difficult to preserve, thus the percentage of sandstone is high. While the sandstone on downthrown side is mostly isolated and in thick single-layer, but the mudstone is more developed. Therefore the sandstone is in low percent. When the fault is parallel to flow direction, the sandstone on upthrown side is less and thin with low percentage; while that on downthrown side is more and thicker with high percentage. |
