Abstract: Due to the special shape of "vertical plate" in fault-karst reservoirs,it is necessary to establish a new flowing material balance(FMB) method according to its flow characteristics. The oil and gas flow model of faultkarst reservoirs was analyzed by graphic approach,and the permeability of the reservoir was calculated according to different flow characteristics and corresponding productivity equations. On this basis,a new FMB method for fault-karst reservoirs was established,and the applicability of the new method was verified by numerical model. The results show that the flow pattern of vertical wells in fault-karst reservoirs is linear flow,which is similar to that of horizontal wells in conventional reservoirs. While the flow pattern of horizontal wells in fault-karst reservoirs is radial flow,which is similar to that of vertical wells in conventional reservoirs. The dynamic reserve difference between the new method and the MBE method is less than 5%. The calculation of reservoir permeability by the new method is closer to the actual well conditions. This study provides a guideline for the dynamic reserve accounting of fault-karst reservoirs.

Key words: fault-karst reservoir, flowing material balance, pseudo steady state flow, bottom hole flowing pres sure, dynamic reserve
