Abstract：Because of limitation in equipments and technical level in that time,the earlier second 3-D seismic exploration (the first 3-D seismic exploration called in this paper) in Shengli Oilfield was characteristic of lower both S/N ratio and resolution in seismic data,which can't meet the needs for oilfield development so that it is imperative to carry out the second 3-D acquisition by using up-to-date exploration techniques and equipments in some prospective blocks.Through the practice of the second 3-D acquisition projects in Tianjia, Yujiazhuang and urban area of Dongying city,the paper considered that key of success in second 3-D acquisition lies in optimum design and scientific demonstration of concrete-surveyed-object-based geometry, meanwhile, it should pay more attention to investigate the surface structure and interference waves and make our best effort to choose optimum shooting and receiving parameters.It is shown by acquired second 3-D data in above mentioned three areas that both S/N ratio and resolution have greatly improved in comparison with the first 3-D data and achieved better geologic results.
