中文摘要: |
海上稠油油藏挖潜受到不连续薄隔挡层、沉积微界面和渗透率差异等方面影响,导致采出程度不高,基于此,开展了稠油油藏流动单元精细划分,在连通砂体间的流动单元和连通砂体内的流动单元研究基础上,分析了7种流动单元影响主控因素,选取以数学手段为主的储层参数分析和以地质研究为主的储层层次分析相结合的方法,综合考虑宏观储层参数和微观储层参数定量影响大小,划分了4类稠油油藏流动单元,各类流动单元与储层沉积微相具有很好对应的关系,流动单元等级越高,采油指数越高,2口生产井验证流动单元划分结果的准确性,流动单元的划分可指导调整井井位部署。 |
英文摘要: |
the exploitation potential of offshore heavy oil reservoir is affected by discontinuous thin barrier, sedimentary micro interface and permeability difference, resulting in low recovery. Based on this, the fine division of flow units in heavy oil reservoir is carried out. Based on the study of flow units between connected sand bodies and in connected sand bodies, the main control factors of seven flow units are analyzed, and the mathematical hand is selected Four types of heavy oil reservoir flow units are divided by the method of combination of the reservoir parameter analysis based on the interval and the reservoir level analysis based on the geological research. Each type of flow unit has a good corresponding relationship with the sedimentary microfacies of the reservoir. The higher the level of the flow unit, the higher the oil production index and the verification flow of two production wells The accuracy of dynamic unit division results and flow unit division can guide the adjustment of well location. |
