油田进入特高含水期开采阶段,油层认识程度的提高,开发技术政策的转变,提高采收率新技术的应用等都对油层的分类标准提出了新的要求。本文利用喇嘛甸油田密井网条件下积累的丰富的静态和动态资料,对各沉积单元进行沉积特征描述,确定砂体的沉积模式,同时对油层的特征参数进行分析,根据数据的分布特征,制定油层分类的标准,判断油层类别,同时完成各类油层储量的评价。
Oilfield into the ultra-high water cut period, the understanding of the reservoir to improve the development of technical policy changes, improve the recovery rate of new technologies are applied to the oil layer classification criteria put forward new requirements. In this paper, we use the abundant static and dynamic data accumulated in the dense well pattern of Lamadian Oilfield to describe the depositional characteristics of each sedimentary unit, determine the sedimentary model of sand body and analyze the characteristic parameters of the reservoir. According to the distribution characteristics of the data, Develop criteria for the classification of oil reservoirs, determine the types of oil reservoirs, and evaluate the reserves of various types of oil reservoirs at the same time.
