Being an important research method for modern oil and gas pool management in recent years, the feasibility of oil and gas pool geophysical detection was discussed in this paper from two aspects of theory and experiment according to Gassmann theory. The paper also pointed out that four-dimensional seismic method and borehole gravity measurement were the main methods for the current oil and gas pool detection. Simultaneously, the “three high” data collection method up to the standards of high repeatability, high signal noise ratio and high resolution of four-dimensional seismic oil and gas pool, the data processing method emphasized on normalized processing and the data interpretation method based on seismic attributes analysis, were all the focal points of this paper. The corresponding effectiveness and actural prospect were also put forward through the forward modeling test and real application processing as a conclusion.
