| 摘 要： | 辽河新生界裂谷型断陷盆地有多种扇三角洲油藏类型，发育规模大到几十平方公里，小到不及1平方公里.实践证明，剩余油分布与储层微相模式有着密切的内在联系.储层分布需要通过建立沉积微相模式来揭示.沉积微相模式的建立需要分析挖潜区块地震相、地震属性特征，地质背景、沉积环境背景、岩石相组合特点和类型及其变化规律与电相类型关系，划分出微相类型，总结各微相特点、展布规模.并利用相关完钻井储层厚度资料，以相带平面图为约束编制储层分布图，揭示出挖潜区块的储层分布特点，为井位部署提供地质依据.多年实践证明，在老油田挖潜增储、新井部署方面收到了良好效果.“沉积微相模式”理论也成为油田开发实践的有效技术. |

| Abstract: | The Liaohe Cenozoic valley-type fault basin has many types of fan delta with oil reservoirs.Its developing scale iS different from less than one square kilometers to dozens of square kilometers.Practice has proved that the residual oil distribution has close intrinsic relationship with the reservoir microfacies mode.The establishment of sedimentary microfacies mode is required for analysing the seismic facies,the characteritics of seismic attributes in potential blocks,the geological background,the background of sedimentary environment,the combination character of rock phase,and its relationship of the changing rules with electrofacies types to establish its sedimentary microfacies,mode and distinguish the type of the microfacies,as well as the microfacies characters,and distribution scale.Using reservoir thickness data from the relative done-drilling,with the limit of the phase band map,it is needed to edit the distribution map of the reservoir to show the distribution character of the reservoir with the potential,and offer geophysical evidence for deployment of the well-location.From years'practice,the theory of sedimentary mierofacies mode obtains better effect in expanding old oilfield potential and deployment of the new wells.It also becomes an efficient practical technology in exploiting oilfields. |
