摘要/Abstract

摘要： 克拉玛依油田五2东区克上组为扇三角洲砂砾岩储层，砂体叠置关系复杂、储层非均质性严重，部分井组注水效果差。综合该区岩心、测井和实验室分析化验资料，对储层的分布和质量非均质性进行了定性分析和精细定量表征；并在相控约束下，利用熵权法计算综合非均质指数进行评价；最后将分析结果与实际生产数据相结合，总结出储层分布和质量非均质性对实际注采效果的影响。结果表明：各砂层组层间质量非均质性中等；层内渗透率以正韵律、复合正韵律和均质韵律为主，质量非均质性较强；平面上在相控约束下的同一砂体内部，储层质量非均质性表现为中等到强。垂向上S5和S1砂层组内部中厚层砂体组合分层多，其余各砂层组表现为孤立单砂体形式；平面上砂体的分布整体受沉积微相控制。储层分布非均质性是造成注采不见效的原因，储层质量非均质性则导致注采见效难，效果差，该结论对油藏下一步调整注采井网和注采措施具有重要意义。

Abstract: The upper Karamay Formation in eastern block Wu 2, Karamay Oilfield, is sandy conglomerate reservoir of fan delta, which is characterized by complex sand body distribution, strong heterogeneity and poor effect of water injection and oil production. The data of core, laboratory analysis and well logging were used to study the heterogeneity of reservoir distribution and quality. The data of practical production and the results of qualitative analysis, fine quantitative characterization and synthesis evaluation obtained by entropy method, were adopted to analyze the effects of the distribution and quality heterogeneity on the performance of actual development measure. The result shows that the inter-layer heterogeneity is generally medium. The permeability of layer is dominated by positive rhythm, compound positive rhythm and homogeneous rhythm, and the reservoir quality heterogeneity is strong. In the same sand-body controlled by facies constraints, the reservoir quality heterogeneity is medium to strong. Vertically, the S5 and S1 sand layers are consist of medium-thick sand bodies and can be divided into many layers, with other layers showing isolated single sand body form. The sand body distribution on the plane is controlled by sedimentary microfacies. The heterogeneity of reservoir distribution leads to inefficiency of injection and production. The heterogeneity of reservoir quality leads to poor effect of injection production. This conclusion is of great significance for adjusting the injection production well pattern and measures.
