Abstract：Oil/gas exploration engineering of reefs is related to multidiscipline, among which the seismic-geologic interpretation is precursor and basis of the engineering. The quality of seismic-geologic interpretation will directly affect the geologic evaluation of reefs and successful rate of reef reservoir exploration. Accurate identification of reefs requires us to know the growing feature of reef-building organism and geologic evolution rule in studied zone, clarify seismic reflection feature of reefs and differential reflection feature from other geologic bodies, and especially it should be noted that application of magnetic and gravity data to develop comprehensive analysis; it can further rely on logging data and core slices to analyze the data in the areas of drilled wells, which can more accurately identify the reefs.
