| 摘 要： | 本文针对克拉玛依五3中区克下组低渗透储层非均质性严重，油田高含水，水驱动用程度低等特点，以精细油藏数值模拟方法详细研究了层内，层间，平面及空间的剩余油分布规律。结果表明：低渗透砂砾岩油藏油水相对渗透率关系复杂多样，总体表现出较差的岩石和流体相互作用；剩余油分布主要受沉积微相，储层非均质和井网系统的控制，在空间上主要存在4种类型的剩余油分布，对于指导该区块挖潜具有重要指导作用。

| Abstract: | Aiming at the high heterogeneity of reservoirs,mid-high water content,low efficiency of water,this paper studies intra-formational,interlayer and planar distribution of remaining oil in detail by using fine reservoir numerical simulation method.The results indicate that the relative permeability carves are various and complex,but fluid rock interaction is poor in generally;sedimentary microfacies,heterogeneity and well pattern are the key factors of remaining oil distribution of low permeability conglomerat... |
