Because of the limitation of geologic feature and information, it is very difficult to clarify the static geologic feature of reservoir at the early development phase. In this paper, as an example of research on the Lower Oil Formation Triassic system in No.1 Tahe oil field, numerical simulation is used for inversion research on the geologic feature, including physical property parameter distribution, crude oil reserves, formation water reserves, water influx rate, influence of intercalation on the basal water, individual well critical producing rate, oil displacement energy, etc. This method reaches a new point combined static and dynamic research, which makes good suggestion for further exploration and development of reservoir.
