Reservoir of low permeability is typical of the reservoir belongs to the Ancient hide reservoir, and it has good exploration prospects, So design science, advanced and reasonable development plan is always a basic principle of Reservoir of Haliar , it is also the primary key to have a high level of oilfield development. This paper expounds the general situation of the oil field, oil field geological characteristics, reservoir engineering design and plan implementation requirements, etc. This design first introduced the features of the landscape, oil field features and generated bination of reservoir, design provided the preliminary judgment for the following。 Then analyzed the structural characteristics of the reservoir and reservoir characteristics, provides the basis for the following design。 Then according to the actual situation of the judgment that the reservoir belongs to the normal pressure and temperature and the nature of the crude oil reservoir system。 And then based on the reservoir physical property characteristics of seepage make relative permeability curve. Finally, through the different methods to determine the oilfield development mode, the well s and well spacing and recovery.
