Fan Zifei; Fu Xiujuan&. Fang Hongchang
This paper derives productivity formuh and water breahhrough time of horizon-tal wells in a reservoir with gas cap and bottom water drive, During the process of deriva-tion, the influences of oil gas interface at the top of the reservoir, oil water interface at thebottom of the reservoir,reservoir anisotropic ratio and position of a horizontal well to poten-tial distribution are considered.The results obtained are useful for reservoir engineeriiig de-sign and theoretical study of horizontal wells.
