Based on the feature that the development methods of the fault-block reservoir vary in different parts，a partitioned control technique of well pattern was put forward. Considering the structural and flowing characteristics of the fault block reservoirs，the first level of reservoir partitioning technique was established，and the reservoir can be divided into 8 parts generally which can be summarize into 3 patterns：angle controlled region，fault controlled region and well controlled region. According to the distribution of remaining oil，the second level of reservoir partitioning was divided into enriched area of remaining oil，weak enriched area of remaining oil，water-flooded area and strong water-flooded area. Then the well pattern partitioned control method for different regions was determined based on analyzing remaining oil characteristics and control factors. Different kinds of fault block reservoir can be seen as a combination of different types of regions，and the combined development method can be further determined：the production well should be deployed in structure high site near the fault and close to the vertex of the angle between two faults，and the injection well ought to inject outside the edge using staggered line-drive pattern. This technique was applied to Xin10 fault block with good results，and the 10-year cumulative increased oil will be 2.53×104 t and EOR will be 4.6% after it was predicted by numerical simulation.
