摘　　要：碳酸盐岩潜山储层蕴含资源量巨大,勘探前景广阔,是胜利油田的接替新领域。碳酸盐岩潜山油气藏多受构造活动、岩性变化和流体溶蚀等影响,其内幕储集空间非常复杂,油气开发难度大,准确地描述裂缝空间分布是潜山油藏开发的基本前提。这里以胜利油区富台潜山为例,通过研究该区域的地质背景并结合测井、地震资料对其进行地层划分,以深度学习为辅助手段实现了对全区进行高效的裂缝预测;在裂缝预测结果基础上进行断缝溶储集体刻画,并结合多地层的古地貌准确直观地展示了刻画结果。Carbonate buried hill reservoir has vast resources and broad exploration prospects,a new field of succession in Shengli Oilfield.Carbonate-buried hill reservoirs are affected mainly by tectonic activities,lithologic changes,and fluid dissolution.The inner reservoir space is very complex,and the oil and gas development is difficult.An accurate description of fracture spatial distribution is the basic premise of buried hill reservoir development.In this paper,taking Futai buried hill in Shengli Oilfield as an example,through studying the geological background of the region and combining with logging and seismic data,the strata are divided,and deep learning is used as an auxiliary means to realize the efficient fracture prediction in the whole area.Based on the fracture prediction results,the fracture-dissolution-reservoir collective is characterized,and the characterization results are displayed accurately and intuitively in combination with the paleogeomorphology of multiple strata.
