Reservoir pressure prediction of gas condensate reservoir with oil rim
摘要
Abstract
During the concurrent development of condensate gas cap an d oil rim, retrograde condensation, escape of dis-solved gas, connate water evaporation, expansion of rock and fluid and external water invasion would occur with the decline of reservoir pressure. Taking the above factors into consideration, a reservoir pressure prediction method for gas condensate reservoir with oil rim was proposed based on the material balance principle. The computational method for reservoir pressure was used in an actual gas condensate reservoir with oil rim. The application results show that the reservoir pressure obtained by this method coincides with the actual measurement, which proves the effectiveness of the method. Meantime, the increase of gas recovery rate or oil recovery rate can speed up the decline of reservoir pressure under depletion development. When the pore volume of gas cap is larger than that of oil rim, the increase of gas recovery rate can deplete the reservoir pressure more easily than oil recovery rate, which indicates that gas recovery rate can't be too large.关键词
