摘　　要：作为常规油气资源的有效接替,页岩油气在非常规能源中异军突起,成为全球油气资源勘探开发的新亮点,而页岩油也成为近期研究热点。但是在页岩油实施过程中,经常会受到地质条件的影响,如地层起伏较大、微构造发育、横向岩性变化快、非均质强、含油性差异大等,给水平段设计和导向带来很大难度。为了准确识别甜点,提高甜点钻遇率,通过建立三维地质模型,将地震资料解释结果与各类属性在深度域结合,实现了页岩油三维甜点在三维空间的直观化与可视化。将三维地质模型和Petrel特有的导向技术相融合,能够快速、准确、高效地对水平井的轨迹进行调整与优化。As an effective replacement for conventional oil and gas resources,shale oil and gas have emerged as a new bright spot in global oil and gas exploration and development in unconventional energy sources,and shale oil has also become a recent research hotspot.However,in the implementation process of shale oil,it is often affected by geological conditions,such as large geological undulations,well-developed microstructures,rapid lateral lithological changes,strong heterogeneity,and significant differences in oil content,which pose great difficulties for the design and guidance of horizontal sections.In order to accurately identify sweet spots and improve their penetration rate,a three-dimensional geological model was established to combine seismic data interpretation results with various attributes in the depth domain,achieving the visualization and visualization of shale oil three-dimensional sweet spots in three-dimensional space.By integrating 3D geological models with Petrel’s unique guidance technology,it is possible to quickly,accurately,and efficiently adjust and optimize the trajectory of horizontal wells.
