Abstract: Even though great successes have been made in the South Yellow Sea in the field of seismic survey for Mesozoic-Paleozoic marine hydrocarbon,problems still remain. There are difficulties to reduce the disturbance in original data acquisition in bad environment,difficulties in recognition and suppression of multiple wave under the complex wave field, and difficulties in accurate seismic imaging for complex structure conditions. After careful analysis of these problems, we put forward following suggestions: 1) re-positioning the survey process, 2) strengthening the basic theory research, 3) encourage technological innovation in data acquisition and processing, and 4) effectively carrying out integrated geophysical survey.
