Horizontal Well Development Of Reservoir With Bottom Water And Gas Cap Technology Policy Research

Since 2001,Sinopec to do overseas exploration and development projects,as of 2009,it has 33 exploration and development projects in 20 countries.Studying for the main reservoir types of statistics in Nigeria area,the total gas cap and bottom water reservoir types accounted for 75%,it accounted for the vast majority of production and block.It has great difficulty in the gas cap and bottom water reservoir because of its oil and gas distribution and water flow characteristics of complexity for the development has brought.So it has great significance for the study of gas-cap mining method bottom water reservoir.This paper focuses on technology policy on foreign gas cap reservoir properties of bottom water reservoir development by horizontal wells,its based on the case which located the West Africa and Niger Delta M&B Reservoir.Combining with field data,through the analysis of reservoir performance,summarizing the factors which influenced development effect and the factors that influenced the development and the effect of the reservoir based on the establishment of a typical model type gas cap and bottom water reservoirs were Mechanism.From the inside the reservoir characteristics,the development of vertical wells,horizontal wells three aspects separately,summed up the development of appropriate technology policy.Then establishing the geological model,applied in horizontal well optimization design based on the results of the study,and make a dynamic prediction.The research content for later type bottom and gas cap reservoir with horizontal well development to provide certain theoretical basis.
