Abstract：The 3D multi-wave seismic exploration is hot-point studied in seismic exploration currently. In face of difficulties in converted wave data processing such as large dynamic range of frequency in digital geophone, producing serious noises with higher and lower frequencies, unable to acquire correct CCP of 3D data and large offsets and non-symmetric ray-path and anisotropic influence making difficult in acquire accurate converted wave velocity. Using polarization filtering for denoise, 3D rotation, CCP positioning of 3D converted wave, 4-paramter analysis and prestack time migration in converted wave processing can better solve abovementioned issues by case of processing of 3D converted wave data acquired by single-point digital geophone in Keng-71 zone of Shengli Oilfield.
