摘要
隔夹层是形成陆相储层流体流动非均质的主要原因之一,是控制厚油层复杂水淹形式的主要地质因素.孤岛油田自1990年进入特高含水期后,油层水淹严重,剩余油分布零散,因此隔夹层研究对于剩余油挖潜和提高最终采收率具有重要的意义.以孤岛中一区馆6砂组为例,利用岩心标定测井资料,提出不同类型夹层识别方法,并结合灰色理论对隔夹层进行综合判别.
The interlayer is the main cause to form the heterogeneity of fluid flow in the continental reservoir and is also the major geological factor for controlling complex water-flooded modality of thick layer.Since Gudao oilfield came into the stage of high watered,the oil layer watered seriously,remaining oil is scattered,hence,the research of the barrier beds and interbeds has the important significance to exploit remaining oil and improve ultimate recovery.This article takes the example of Guantao-6 of Zhongyi area,applied the log information and grey theory to distinguish the barrier beds and interbeds.
