摘要(Abstract):

在喇嘛甸油田5-361井区厚油层精细解剖研究成果的基础上,以地质统计学为理论依据,利用RMS软件储层随机模拟的优势,建立厚油层内部建筑结构模型,精细描述储层内部建筑结构间不同类型的隔层空间分布和建筑结构内砂体、结构界面、夹层的三维空间分布,并以砂体、结构界面及夹层的空间分布为约束条件,精细描述厚油层内部的非均质性。同时,通过精细油藏数值模拟研究,量化了剩余油分布状况。并针对油层动用状况,优化了注采井的各项措施方案,有效改善了区块的开发效果。
Inner structure modeling of thick layers in Lamadian Oilfield is established based on the achievements obtained from accurate dissection on thick layers of well field 5-361,taking advantages of the RMS software for random reservoir simulation,and theoretically,with reference to geostatistics. Through inner structure modeling,spatial distribution of different barrier layers could be precisely described as well as the distribution of sand body,structural interface,and interbeds within the thick layers,which,in addition,if taken as restrictions,internal heterogeneity of thick layers could also be finely interpreted.Meanwhile,remaining oil distribution could be quantified by fine numerical simulation on reservoir.In terms of the producing status of layers in the studied area,treating plans for injectors and producers are optimized,which effectively improved the development effect of the well field.
