摘　　要：结合实际工作中微构造分析方法在准噶尔盆地储层油藏描述研究中的应用,认为它们在油藏描述中的重要作用体现在以下几个方面:主要在弥补大层段、大等值线间距绘制下难以发现的砂体顶面或底面的微细变化,会发现与原地层构造总趋势一致而局部又不尽相同的微幅度构造或微体差异、在背斜构造-岩性油藏中,通过微局部分析确定更准确的含油边界、经过精细储层微构造分析排除假断层。结合多个区块的生产特征,具体分析了各类微构造对开发的影响,得出了在油藏开发前期和后期尽可能把采油井优先布在正向微构造上,把注水井尽可能布在负向微构造上的认识。对研究区的砂岩、砾岩多个区块储层微构造与油水井生产动态特征分析后进一步提出:油层微结构对油水井生产动态的影响作用是显著的,但不具唯一性。最终得出开发阶段为了精细刻画储层内部单砂体,用微构造分析的方法精细成图是体现研究深度的必要手段。Since the idea of micro structure was brought up, it has been widely used. In combination with application analysis of micro structure in the description of reservoir in Zhungar Basin, pointed out its important functions in the description of reservoir; to recover the subtle changes on the top surface and basal bottom of the sandy body ; to find some micro range structures and micro differences identical to the general trend of the original strata structure but varied locally ; to determine more accurate oil bearing borders through micro local analysis in anticline structure-lithologic reservoir; to exclude false fault through micro structure analysis on fine reservoir. The authors discussed the influence on development of reservoir by micro structures in combination of production properties of several blocks, identified the influence of micro structure of oil layers on the dynamic state of oil and water wells.
