Lithologic and stratigraphic oil and gas reservoirs have some difficult technological issues, such as difficult identification of trap and difficult prediction of the formation conditions for the oil and gas reservoirs. To solve those issues in exploration of the lithologic and stratigraphic oil reservoirs in Erlian Basin and Jizhong Depression, a lot of advanced and applicable technologies have been adopted such as sequence stratigraphy, high-resolution seismic processing, high-precision level calibration, 3-D visualized interpretation, seismic multi-property analysis, reservoir inversion and integrated appraisal on oil and gas layers. The applied practice indicates that the satisfactory results have been achieved in preliminary exploration of the oil and gas reservoir, trap evaluation and oil reservoir description by means of those technologies. Meanwhile, a series of technologies and application theories for exploration of subtle oil reservoirs at the different stages have also been explored and summarized.
