The strong bottom water condensate gas cap reservoirs in Tahe Oilfield is the sandstone reservoir composed of gas cap, oil reservoir and large scale of bottom water. In the process of development, gas channeling or oil channeling exists due to the uneven production of gas cap and bottom oil, and the development effect is poor. According to the actual production situation of gas cap reservoirs with massive bottom water in block T of Tahe oilfield, and considering the gas-oil ratio and density changes in the production process, a new method to split gas cap and reservoir ground production, integrated splitting method for single-well production stage, is explored. By this method, recovery rates of crude oil, condensate, condensate gas and dissolved gas in gas cap reservoirs are calculated, which are 12.28 %, 22.96 %, 29.75 % and 12.05 %, respectively. The calculated results are compared to that of the similar reservoirs at home and abroad, and it is found that they are matching the development characteristics of such reservoirs, and the field operation is relatively simple. Through the calculation of the oil recovery for the gas cap reservoirs, the development status is understood, and the problems existing in the development and the development potential of the block are timely discovered, so as to develop gas cap oil reservoir more reasonably.
