【摘要】：随着二次开发重建井网结构调整,扶余油田形成了一线状注采井网为主的新的井网格局。然而新井网的形成,导致无效水循环严重、含水上升加快、新井产量快速递减等矛盾也日趋严重。同时,多年的注水开发和不断调整,油藏地质开发特点明显变化,地下剩余油分布规律更加复杂,对扶余油田目前所处的开发阶段来说,剩余油的认识仍不够深入,难以满足油田精细开发需求。本文在吸收前人研究成果基础上,通过对近年来密闭取芯井详细观察和描述,分析各项化验资料基础上,以岩心为基础,开展储层沉积特征分析、储层夹层与构型分析、渗流规律研究及剩余油等研究,进一步深化油层认识,建立对隔夹层及单砂体内部结构界面岩心及测井识别模式,明确不同韵律水驱油效率以及不同韵律储层的剩余油分布特征。为实现扶余油田精细化开发提供数据和理论基础。
[Abstract]:With the readjustment of secondary development and reconstruction well pattern, a new pattern of linear injection-production pattern has been formed in Fuyu Oilfield. However, the formation of new well pattern leads to serious invalid water circulation, rapid increase of water cut and rapid decline of new well production. At the same time, after years of water injection development and continuous adjustment, the characteristics of reservoir geological development have changed obviously, and the distribution law of underground remaining oil has become more complicated. The understanding of remaining oil is still not deep enough for the stage of development in Fuyu Oilfield at present. It is difficult to meet the needs of oil field fine development. On the basis of absorbing the previous research results, through the detailed observation and description of the closed coring wells in recent years, and on the basis of analyzing all kinds of laboratory data, based on the core, the paper carries out the analysis of the reservoir sedimentary characteristics, the intercalation and the configuration of the reservoir. The study of seepage law and remaining oil further deepens the understanding of reservoir and establishes the core and logging identification model of intercalation and internal structure of single sand body. The oil displacement efficiency and residual oil distribution of different rhythmic reservoirs are determined. It provides data and theoretical basis for fine development of Fuyu oilfield.
