黄骅坳陷高尘头地区深盆油藏油气聚集及物理模拟实验研究

THE STUDY ON OIL AND GAS ACCUMULATION OF DEEP BASIN RESERVOIR AND PHYSICAL SIMULATION EXPERIMENT IN GAOCHENTOU AREAS OF HUANGHUA DEPRESSION

黄骅坳陷高尘头地区东营组油藏是顶油底水深盆油藏.在对该地区深盆油成藏机理及控制因素综合研究基础上,运用储层物理模拟实验,深入分析储层均质和非均质砂层油气运移和聚集机理.物理模拟实验证明,各砂层渗透率和厚度差异对油的运移方向、路径和充注层位是重要影响因素,同时验证储层非均质性对成藏的控制作用.

The Dongying Formation reservoir in Gaochentou areas of Huanghua depression is the deep basin with the top oil reservoir bottom water reservoir,on the basis of comprehensive study on the oil accumulation mechanism of deep basin and the controlling factors in this region,using reservoir physical simulation experiments,in-depth analysis of homogeneous and non-homogeneous sand reservoir oil and gas migration and accumulation mechanism,the physical simulation experiment proved that the difference between sand permeability and thickness of the oil migration direction,path,and filling the horizon are important influencing factors,and it is also verified that the reservoir heterogeneity can control the reservoir forming.
