%X The basic petroleum geological condition analysis is the premise for oil-gas exploration, but the particularity analysis is the key point for finding the most effective cut-in way for oil-gas exploration. The particularity of subtle traps formation and subtle reservoirs mainly show in the following points: the property of Tuha basin and structure characteristics- a long and narrow multi-recycle stacked basin; sedimentary system-two directions (north and south) short sediment sources sedimentary systems; the geological background of subtle reservoir-lower generation and upper reservoir, structural slope character of south slope; subtle traps for oil-gas occurring-fault connected with source rock and lateral fault must be existing; subtle reservoir-space accumulated with oil-gas of subtle traps are small, sandstones for oil-gas reservoir are thin and reserves of single trap are small. According the conditions mentioned above, the subtle reservoirs exploration of Shengbei depression must be clinging to stated structural background, and the south wing of Shengbei structural zone, a crossover region of north and south sediment sources, is an available area for subtle traps developing and subtle reservoirs exploration.
