摘要
///The Yingshan Formation of Middle-Lower Ordovician in Tazhong uplift in Tarim is an important fracture and karstmodified carbonate reservoir. On the basis of integrated information revealed by a variety of methods, such as geophysical methods including prestack fracture prediction technology, paleo-geomorphological analysis technology, seismiclogging wave impedance inversion technology, three-dimensional seismic attribute extraction technology, and well-logging explanation, core observation etc., the four types of reservoir units including fracture-dominated, vug-dominated, cave-dominated and complex can be identified and mapped in this area, these reservoir architectural units genetically formed in epigenetic and hydrothermal karst modification, fracturing.
