摘要
平南潜山油气藏属于"新生古储"型组合,主要为奥陶系、寒武系碳酸盐岩。裂缝是储层内油气的主要储集空间,寻找岩层内的裂缝是潜山油气藏勘探的关键。根据裂缝在几何属性上的表现,提出了用多种几何属性预测与描述储层中的裂缝体系,定量刻画裂缝的分布,取得了较好的效果,与实际钻井资料相吻合。
The Pingnan buried hill hydrocarbon reservoir is a combination of new source rock and old reservoir, dominated by Ordovieian and Cambrian carbonate rocks. Fractures constitute the main accommodation space for petroleum in the reservoir, and the key to the exploration of the buried hill hydrocarbon reservoir is to find fractures in rocks. According to geometrical properties of the fractures, this paper puts forward a method for forecasting and describing the fracture system in the reservoir based on multiple geometrical proper- ties. This method can describe the distribution of fractures quantitatively, and the test results have been proved by the drilling data.
