摘　　要：岩石物理相是多种地质作用的综合反映,是沉积、成岩、后期构造、流体改造作用下的成因单元。通过确定岩石物理相,可以提高储层物性参数及水淹层的解释精度,更好地确定剩余油的分布。因此,基于实际资料制定了L油田岩石物理相的划分标准,并依据划分的岩石物理相建立其参数的定量解释模型和水淹级别划分标准,进而确定了水淹规律、剩余油分布与岩石物理相的关系,同时证明了L油田水淹层解释结果的正确性。Petrophysical facies is the comprehensive presentation of various geological actions and genetic unit re- suited from the sedimentation, diagenesis, late structures and fluid remoulding action. By means of the determina- tion of the petrophysical facies, the interpretation preeisions of the physical property parameters of the reservoirs and watered-out layers can be improved, thus the distribution of the remained oil can be better determined. Therefore based on the actual data, the dividing standards of the petrophysical facies in Oilfield L are established, and moreo- ver according to the determined facieses, the quantitative interpreting model for the parameters and dividing stand- ards for the watered-out level are established. Besides the relationships between the petrophysical faeieses and wa- tered-out rules and remained oil distribution are ensured, at the same time, the accuracy of the interpreted results of the watered-out layers in the oilfield is proven.
