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。
Because the bottom water reservoir of sandstone is different from limestone reservoirs in mining, it is necessary to study the mining characteristics of sandstone bottom water reservoir and its influencing factors. The three-phase three-phase black oil model was used to analyze single well oil production, reservoir sedimentation rhythm, vertical horizontal permeability ratio, interlayer size and position, edge water energy, oil-water viscosity ratio, well spacing, well blowout degree, Capillary pressure and other 9 factors on the recovery of sandstone bottom water reservoir. The results show that the main factors affecting the bottom water coning are single well oil production, interlayer size and location, vertical horizontal permeability ratio, reservoir deposition rhythm and oil-water viscosity ratio.
