摘要
浅层不能生成油气,浅层成藏要有沟通深层油气源的断层,油气沿断层由深层运移至浅层的过程中可能留下足迹,足迹在地震剖面上有多种表象。统计足迹的表象特征,分析油气运移足迹的成因机理,是研究浅层油气成藏的有效手段。气烟囱等油气运移足迹的识别方法,是在生产中总结出并不断得到验证的经验,对生产有很好指导作用。
Abstract
Hydrocarbon can not be generated in shallow zone. The formation of shallow reservoirs needed the fault that connected source rocks and reservoirs. In the process of migration from source rocks to sandstones, hydrocarbon left traces. There were a lot of phenomena to recognize traces appeared on seismic sections. It was an effective method to research on the formation of shallow reservoirs by analyzing the forming mechanism of traces. Gas chimney and other trace migration recognition methods was summarized and verified during hydrocarbon exploration, and these methods can guide production very well.
