Development Model and Quantitative Prediction of Igneous Rock in S Oilfield, the Bohai Sea Area

The structure of S Oilfield Bohai sea area in China is located the low uplift slope zone Dongwa Laibei Huanghekou depression. target interval oilfield belongs to Paleogene layered structural oil reservoir under influence igneous rocks. Due widespread development rocks, and diversity rock types, complex, lateral changes are intense. differences volcanic eruption intensity materials made masses overlap each other, with rapid lithofacies, complex seismic reflection structures. Therefore, it was difficult carry out fine characterization Based on lithofacies model, combination response characteristics mechanisms, this paper summarized three types models mechanisms study area. At same time, through technical means such as stratigraphic slicing, attribute extraction, optimization analysis, spatial distribution various facies zones rocks at different stages were described detail, achieving precise prediction Bozhong Oilfield. During process oilfield, research results guided well locations provided support for efficient oilfield.
