摘要
为进一步挖掘老区潜力、提高油藏高含水开发后期的采收率,通过对营8断块区断裂系统和构造的精细描述解释,结合地质研究和开发动态资料,确定了断裂系统特别是断块内部低级序断层的分级标志,落实了5条Ⅳ级断层、14条Ⅴ级断层,精细的构造解释解决了生产中的注采井油水关系矛盾。在此基础上分析了断裂系统形成机制,从而为确定剩余油分布、部署开发调整方案提供指导和依据。
For the purpose of tapping the potential in the old oilfield and enhancing the oil recovery at the late stage of high water cut,through detail description and explanation of fault system in Block Ying 8 and in combination with geologic research and dynamic information,classification standard of regional faults was established,5 forth-grade faults and 14 fifth-grade faults were obtained.Detail structure interpretation is used for solving the conflicts between production wells and water injection wells.On this basis,the formation mechanism of the fault system is analyzed,it provides a guidance and basis for confirmation of remaining oil distribution and deployment of development adjustment programs.
