摘要
针对喇嘛甸油田特高含水期剩余油高度分散及挖潜难度增大的实际状况 ,在精细解剖各类储层基础上 ,对河流 三角洲沉积的各类储层成因模式及非均质特点进行了系统研究。利用取心井水洗资料及最新完钻井水淹解释成果搞清了不同类型储层目前动用状况 ,确定了不同沉积环境各类储层剩余油形成条件及分布规律。研究认为 ,油田特高含水期开发潜力主要集中在泛滥分流平原环境沉积的厚油层内部。通过系统完善各套开发层系储层的注采关系 ,采取多种途径进行精细挖潜 ,是今后油田综合调整的主要方向。
According to the actual conditions of Lamadian Oil Field, in which the remaining oil are highly scattered with more and more difficulty for potential tapping,and basing on learning the genetic mode and the heterogeneity characteristic of all kinds of fluvial delta depositional system reservoir,this paper studies the current producing conditions of different reservoirs and describes exactly the distribution rule of plane macroscopic and inner deposited layer microscopic remaining oil and evaluate the effect of the remaining oil for potential tapping,which supplies reliable geology foundation and points to the dominant adjustment direction.
