Abstract：Exploration and development in Dongxin area have been done for more than 24 years. The subsurface geological structure and fault system in this area teere not ascertained in many years because of the complicated subsurface geological structure and troublesome surface conditions, so that drilling exploration often failed. Consequently, three-dimensional seismic exploration yeas conducted in this area. First, field acquisition parameters were correctly determined by comprehensively analysing known geological materials, geophysical dataand other conditions in this area. Then some surface obstacles were effectively avoided by taking 17 different field layouts, thus ensuring complete subsurface three-dimensional data point network and uniform multiplicity. Five new hydrocarbon-beaxing blocks and 18 new seismic highs in old hydrocarbon-bearing blocks have been discovered by interpreting these three-dimensional seismic data. 102 wells of 147 completed wells have industrial oil flows, success rate being above 95％.
