【Abstract】 3D converted wave seismic exploration has been becoming the hotspot of seismic exploration in recent years. The key processing techniques of 3D converted wave seismic exploration, including polarization filtering noise suppression, component rotation, converted point position, velocity analysis and pre-stack time migration, etc, are discussed mainly in the paper. Applying these methods to the real 3D converted wave data acquired by digital MEMS (micro-electro-mechanical system) sensors at Ken 71 in Shengli oilfield, good results are accepted and a feasible processing workflow is set up.更多还原
