Abstract


In this paper, edge and bottom water fault block reservoir characteristics, reservoir engineering and simulation applications combined method for optimization of horizontal well development technology research, including: block edge and bottom water reservoir horizontal well productivity influencing factors , edge and bottom water reservoirs in horizontal well development block boundaries economic Policy research , edge and bottom water block horizontal well balanced optimization of mining technology research and block edge water reservoir horizontal well perforating operation mode optimization . Wellbore pressure drop on the impact of horizontal wells studied horizontal length , vertical position of horizontal wells , reservoir thickness , oil viscosity , permeability anisotropy , the production side of the water pressure and location of the horizontal well productivity effects ; from economic point of view , the application of the principle breakeven , we propose a fault block edge and bottom water reservoir horizontal well development economic limit tired fuel, economic limit initial production and economic limit the length of the horizontal section method for determining edge and bottom water for the future fault block oil reservoir horizontal well development evaluation provides a reference ; horizontal wells to mitigate water breakthrough time , to extend the anhydrous oil phase , were balanced horizontal well technology to optimize the exploitation of research, combined with numerical simulation software , and seek to meet off the edge and bottom water block horizontal well balanced exploitation differential permeability , thickness differential and edge water level in the reservoir section and the angle between the oil-water interface and reasonable ; horizontal wells to improve production while maximizing the economic benefits for the level of sub-paragraph perforating operation mode optimization to determine the position of the horizontal section perforated , open degree of opening paragraphs and sub- optimal production plan horizontal section . Through the above optimization study for the block edge and bottom water reservoir parameters related to the development of horizontal wells designed to provide a theoretical basis for the development of better edge and bottom water fault block oil reservoirs have important guiding significance.
