Well BT5 has achieved industrial gas flow in Ordovician Yingshan formation of BT5 well area. Due to strong reservoir heterogeneity anisotropic and varied seismic response characteristics, the difficulties of targets optimization are increased. Based on the research of geology, well drilling and well logging of Ordovician Yingshan formation, combined with previous regional re-search results, through reservoir prediction techniques, such as seismic multi-attribute comprehensive analysis, palaeogeomorphol-ogy analysis, wave impedance inversion, frequency attenuation gradient and model forward, ClassⅠand ClassⅡreservoirs are opti-mized, thereby providing basis for exploration targets optimization and oil and gas breakthrough.
