Abstract: Seismic interpretation must integrate seismic, logging and geological data, and cooperate the multi- discipline workflows. The development of integrated seismic data interpretation system provides such kind of platform. The data platform for integrated seismic data interpretation is the core of the system, which is based on the comparison and analysis of famous hydrocarbon exploration synthetic data model home and abroad, proposes the basic principles and realization path for establishing data platform of integrated seismic data interpretation. After referring the PPDM and POSC data standard in exploration and development for oil/gas, the logical model of seismic integrated interpretation data platform (NEWSBase) is established. Based on the logical model, the object-orientated analysis and object-orientated design are used for developing data platform of integrated seismic data interpretation. Oracle database system, object-orientated programming language (C++) and software component technology have been adopted to complete the rational software implementation for data platform of integrated seismic data interpretation.
