Pattern of Water-production and the Relationship with Reservoir in Horizontal Wells for Development of Condensate Gas Reservoir with Bottom-water
摘要
Abstract
With regard to complicated patterns in water production and effective control over water production in horizontal wells for development of heterogeneous condensate gas reservoir with bottom-water, condensate gas reservoirs with bottom-water in northwestern China have been reviewed to summarize six different structural features of reservoirs penetrated by horizontal wells.With actual production performances data of 30 horizontal gas producers for development of condensate gas reservoirs with bottom-water as the basic data, water-production patterns of different horizontal gas producer have been analyzed.Research results show water production in horizontal gas producers for development of condensate gas reservoirs with bottom-water can be classified into 3 categories.In addition, correlation between different water-production patterns and features of corresponding reservoirs has been highlighted.In this way, it is possible to determine features of reservoir architecture through inversion of water-production patterns in gas producers.Field application data show the correlation can be used to achieve conformity rate between predicted and actual reservoir features of over 82%.Relevant research results may provide scientific techniques and theoretical foundation for development of condensate gas reservoir with bottom-water and to enhance recovery rates of relevant gas reservoirs.关键词
