Shengli Oilfield has entered the middle and later development stages， and higher requirements for development seismic technologies have been set to develop reservoirs and further enhance oil recovery finely. The distribution and connectivity of conventional reservoirs in Jiyang Depression are complex due to different buried depths， multi-stage tectonic movements， various sedimentary types， and other factors. At the same time， constrained by seismic recognition， the well-seismic correspondences of some reservoirs are unclear， limiting the accuracy of fine reservoir characterization. In response to the development needs of different types of conventional reservoirs in Shengli Oilfield， a series of development seismic technologies have been formed through practice. These technologies include multi-method integrated reservoir prediction technology for middle and shallow fluvial facies reservoirs，integrated fine description technology for fracture systems in complex fault block reservoirs combing fine fault edge depiction and multiple attributes， prediction technology for middle-deep reservoirs with low permeability， and description technology of buried hill reservoirs fusing multiple parameters of“ fault-fracture-dissolution composite storage space.” These technologies provide strong support for reservoir development. However， as the target reservoirs for development get deeper，thinner，and smaller and expand into unconventional reservoirs， the development seismic technologies faces higher requirements and challenges. It is necessary to accelerate the integration process of processing and interpretation， strengthen the theoretical research of rock physics，promote the application of OVT domain pre-stack inversion in the description of multi-type oil reservoirs，tackle the fine description technologies of complex fault block-lithofacies reservoirs， break through the technical bottleneck of well-ground joint acquisition and gravitymagnetic-electric-seismic technology， and realize the application of artificial intelligence technology in the development seismic field，so as to further promote reservoir development.
