摘要
鉴于砂岩底水油藏开采特征有别于灰岩层水油藏，因此有必要研究砂岩底水油藏的开采特征及其影响因素。利用三维三相黑油模型分析了单井产油量、储层沉积韵律、垂向水平渗透率比、夹层大小及位置、边底水能量、油水粘度比、井距、油井射开程度以及油水毛管压力等９种因素对砂岩底水油藏开采效果的影响。结果表明，影响底水锥进的主要因素是单井产油量、夹层大小及位置、垂向水平渗透率比、储层沉积韵律和油水粘度比。
The effects of production rate, formation sedimentary rhythm, ratio of vertical to horizontal permeability, size and position of an impervious break, volume of aquifer, ratio of oil to water viscosity, spacing of wells, perforation interval and capillary pressure on the production performance of a sandstone reservoir with bottom water are researched and analysized by means of black oil model. The results obtained indicate that the size and position of an impervious break, vertical-to-horizontal permeability ratio, onto-water mobility ratio and production rate are critical parameters affecting the water coning behavior in sandstone reservoirs with bottom water drive.
