摘要
quot;EnDivSummary">Fractures play a very important role in the improvement of low-permeability clastic reservoir properties. On the basis of basin analysis and reservoir studies, both the relationship between fracture of the Kc Formation and regional tectonic stress cracks, and the relationship between sedimentary facies and lithology are studied through sequence stratigraphy and geological statistical analysis. The research findings reveal that there are NE and NW direction stresses that influence fracture in the work area, which form high-angle fractures of NE direction. On the basis of geological understanding, the fracture network model is established.
