| 摘 要： | 利用近4000口开发井初期产能资料，结合构造、测井解释、沉积微相和报废井类型等静态地质资料，对松辽盆地三肇凹陷葡萄花油层的油水分布规律进行了系统分析。研究表明，三级构造内单个的局部构造或单个的局部构造群控制油气的最终成藏，三级构造内油水分布受单个的局部（构造、岩性）圈闭控制，单个的局部（构造、岩性）圈闭内具有统一的油水分布规律，相邻的不同单个的局部（构造、岩性）圈闭具有不同的油水分布规律；储层的发育特征控制了油水的分布层位，断层与砂体的空间配置控制油水的分布边界。在相近的条件下，地垒型断块构造油藏〖FY〗反向正断层—鼻状构造油藏“人”字型反向正断层组合油藏断层—微幅度油藏断层—岩性油藏岩性油藏其它类型油藏，控油能力逐渐减弱。

| Abstract: | Based on initial potential data of nearly 4000 production wells and static geologic material including the structure, logging interpretation, sedimentary microfacies and types of abandoned wells, oil—water distribution regularity in the Putaohua oil layer in the Sanzhao Sag, Songliao Basin, was systematically analyzed. Single local (structure, lithologic) trap controls final hydrocarbon accumulations and distribution of oil—water in the tertiary structure. Distribution regularity of oil—water is unifying in the single local (structure, lithologic) trap. Distribution regularity of oil—water is different in adjacent and different single local (structure, lithologic) traps. Layers of oil—water distribution are controlled by distribution characteristics of reservoir, and boundaries of oil—water distribution are controlled by the array modes of fault and sandbody. In similar conditions, oil-control capacities are weakened from horst fault-block reservoirs→antithetic normal fault structural nose reservoirs→herringbone antithetic normal fault reservoirs→fault—microstructure reservoirs→fault—lithologic reservoirs, lithologic reservoirs→other reservoirs. |
