摘要:
复杂断块油藏纵向上油层多,平面上油砂体发育面积小,平面非均质性强,难以构建规则井网均匀驱替,同时受储层各种封闭边界影响,水驱过程中易形成死油区,为了更加精准计算水驱储量控制程度,更好地评价油藏的井网合理性与完整性,找出井网调整和加密潜力,针对常规方法的不足,提出了更加适用的新方法,即网格储量法。通过提高平面上井网内储量控制面积的划分精度,结合储层地质条件及储层非均质差异,以注采井组为基本单元,逐层网格化井网控制地质储量,对网格化的地质储量进行分类统计,找出复杂边界造成的死油区,进而计算区块注采井网控制程度、水驱储量控制程度,最终得到井网调整加密潜力。将该方法应用在南堡101断块井网适应性评价中,找到了复杂边界造成的井网未控制未动用区域,通过加密调整取得较好的挖潜效果,证明该方法在复杂断块油藏水驱储量控制程度评价有较好的适应性,可以推广至其他复杂断块油藏。
