Abstract

Development of bottom water reservoir with horizontal well can effectively slow down water coning and avoid early water breakthrough in oil wells, which promotes the extensive application of horizontal well in bottom water reservoir. In this paper, literatures about horizontal well are investigated, and the latest research trend is summarized. All factors such as reservoirs, fluid property and production mode to influence horizontal well performance in bottom water reservoir are systematically studied by using reservoir numerical simulation. Based on the calculation results of reservoir parameters of the pilot area, comprehensive analysis to the key factors which affecting horizontal well performance is carried out and the influence degree of various factors on oil recovery is obtained. In a word, the research results in this paper can provide criteria for the design or optimization of horizontal well development in bottom water reservoir.
