喇嘛甸油田储层微观结构特征变化规律研究

Research on variation rule of reservoir microscopic structures and features in Lamadian Oilfield

喇嘛甸油田经过30多年的开发调整,储层微观结构特征发生了一定的变化。本文利用喇嘛甸油田不同时期的取心井、油田化验等资料,研究了储层微观结构特征参数及各微观属性参数关系,分析了注水后储层微观结构特征参数的变化规律。正确认识上述参数的变化规律及现阶段油藏参数的特点,对于搞好喇嘛甸油田的精细挖潜、三次采油、注水开发调整等项工作,具有十分重要的现实意义。

Reservoir microscopic structures and features certain change after development adjustment over 30 years in Lamadian Oilfield. Based on coring well data and oilfield test data in different periods of Lamadian Oilfield, This paper studies relationships between reservoir microscopic structure and feature parameters and all microscopic property parameters, and analyzes variation rule after water injection. Correct recognition on variation rules of above parameters and reservoir parameters characteristics in current stage is very important for future potential tapping, EOR and water flooding development adjustment.
