Based on the space-time relationship of seismic data structure characteristics, the authors can interpret the oil and gas layers quantitatively and find the oil-gas distribution rules on the seismic profile, so as to further improve the precision of reservoir prediction. Through the study on the space-time relationship of seismic amplitude for the main gas layers found in Well Kela-2 in Kela-2 Gasfield and Well Puguang-5 in Puguang Gasfield, the gas-layer boundary can be identified clearly, providing a strong basis for reserves estimation. This research method applies well to the target layers with depth of 200-7 000 m and thickness of over 5 m,in the oil-gas provinces of various lithologies and sedimentary facies (marine, paralic and continental facies). The prediction accuracy can reach over 80% on average.
