【摘要】 本文推导了气顶底水油藏水平井产能公式和见水时间。在推导过程中考虑了油藏顶部油气界面、油藏底部的油水界面、油层各向异性比值及水平井位置对水平井势分布的影响。所得的结果对水平井油藏工程设计和理论研究具有一定的指导意义。更多还原

【Abstract】 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.更多还原
