摘要(Abstract):

利用海拉尔潜山油藏开发过程中取到的大量动、静态资料,系统地论证了油气沿不整合面、断层和砂体运移的规律性,明确了油气运移优势通道的控制因素。油气运移的优势通道是构成含油气系统理论研究中输导体系的最基本通道,优势通道的确定,填补了成藏体系研究方面输导体系中断层、连通砂体和不整合面等最基本通道的控制因素研究的空白,为应用流体势理论定量描述油气运移路径和优选含油富集区块奠定了基础。
This paper uses a large amount of dynamic and static data which are obtained in the process of development in Hailaer burial hill reservoir,to demonstrate migration rules generated from hydrocarbon along unconformity surface,faults and sandbody,and understand control factors for hydrocarbon migration dominant channel.The dominant channel for hydrocarbon migration is the most fundamental channel of transmission system in hydrocarbon theoretical study.It is the first time of most fundamental channel control factors study in transmission system on the aspect of reservoir system,providing foundations for applying fluid potential theory to quantitatively describe hydrocarbon migration path and optimize enrichment blocks with oil.
