This paper, aiming at the narrow sand body and thin oil-bearing bed in Putaohua reservoir in eastern Daqing area, introduces a seismic interpretation software and applies the seismic technology to recognize small faults, small sand bodies and small structures, which has increased the drilling efficiency. To the complicated reservoirs and oil-water relation, the author employs fine structure interpretation, undee aberration technology, fuzzy NN, multi-well inversion, reservoir modeling and forecast, seismic facies interpretation and 3D visualization to increase the descriptive precision of complicated reservoir, and applies the stacked processing technology of 3D seismic data to provide a technical support for the drilling development in the eastern Daqing area.

As oil field exploration technology develops, 3D seismic data have been covering the vicinity of Daqing oilfield. In order to understand the structure, lithology in this area and to look for new reserve, it is necessary to process and interpret the oil exploration data. This paper, taking Putaohua and Fuyang oil-bearing sequences as target beds, processes and interprets the 3D seismic data in Sanzhao area in high resolution. Combined with geology, logging, oil testing data, sedimentary facies, prioritizes the favorable oil-bearing areas, discovers a few oil-bearing blocks, which have been put into production. The joint processing technology has been proved for its validity.
