摘要:
 克拉玛依油田五2东区克上组油藏整体处于开发中后期,剩余油分布规律不清,沉积相研究及其分布规律长期制约着油田生产开发。在系统的岩心观察与精细描述的基础上,应用研究区丰富的密井网资料,并结合粒度分析资料,对研究区水动力环境和沉积相类型进行了探讨,确定研究区为扇三角洲沉积体系,总结了沉积相模式特征,识别出辫状分流河道、水下分流河道、心滩、溢岸、水道间、前三角洲泥等6种微相类型;采用基准面旋回对比方法,在研究区克上组识别出3个向上变浅和2个向上变深的非对称中期基准面旋回,并结合等高程、前积、相变细分对比等多种方法综合划分小层;以沉积发育模式为指导,平剖结合,再现了研究区克上组沉积相形态特征及展布规律;在基准面旋回控制下,研究区扇三角洲相储层砂体主要发育多层式、叠加式、多边式、对接式、孤立式5种砂体叠置模式,分析了可容纳空间变化对单砂体叠置模式的影响。
Abstract:
 The reservoir of the Upper Kalamay Formation in eastern Wu 2 Area of Karamay Oilfield is in the middle and later stages of development. The remaining oil distribution law is unclear, and sedimentary facies study and its distribution law have restricted the oilfield production and development for a long time. Based on the observation and detailed description of the core, the hydrodynamic environment and sedimentary facies types were studied by analyzing dense well network data and granularity data. The study area was identified as fan-delta depositional system, and the characteristics of sedimentary facies model were summarized. The results show that there are six types of microfacies such as braided distributary channel, underwater distributary channel, channel bar, overflow bank, inter-channel and front delta mud. Based on the method of base-level cyclic regression, three shallowing upward and two deepening upward asymmetric intermediate base-level cycles were identified in the study area. Combined with equal height, foreset, phase contrast subdivision and other methods, the small layers were identified. Based on the sedimentary model, the sedimentary facies characteristics and distribution law of Upper Kalamay Formation in the study area were reproduced. Under the control of base-level cycle, the sandbody of the delta facies in the study area was mainly divided into five types of sandbody superposition models: multi-layer, superposition, multilateral, docking, isolated type. The influence of the spatial change of the accommodating space on the single sand body overlaying mode was analyzed.
