摘要
针对滨岸相储层非均质性研究存在不足的现状,在分析超深探边技术原理及影响因素的基础上,开展了南海珠江口盆地陆丰A油田滨岸相储层构型解剖研究,建立了地层电阻率与储层物性的相关关系;并以前人研究的滨岸相储层构型模式为指导,解析了超深探边资料包含的储层信息,直观描述了3~4级构型单元及界面的空间展布。研究结果表明,滨岸相储层具有较强的非均质性,4级构型界面控制了“屋檐油”等剩余油富集区,3级构型界面表现为储层内部的非均质条带,控制了局部油水不均衡驱替。该研究可为剩余油挖潜以及类似油藏研究提供参考。
In view of the current situation of insufficient research on the heterogeneity of waterfront reservoirs,based on the analysis of the principle of ultra deep edge detection technology and influencing factors,an anatomical study on the configuration of shore facies reservoir in Lufeng A Oilfield in the Pearl River Mouth Basin,South China Sea has been carried out,and the correlation between formation resistivity and reservoir physical properties was established.Guided by the previous research on the configuration model of coastal reservoirs,the reservoir information contained in ultra-deep exploration data was analyzed,and the spatial distribution of 3-4 level configuration units and interfaces was described.The research results indicate that coastal reservoirs have strong heterogeneity,and the 4-level configuration interface controls the remaining oil enrichment areas such as"roof oil".The 3-level configuration interface is characterized by heterogeneous bands within the reservoir,controlling local oil water imbalanced displacement.This study provides a good reference for tapping the remaining oil potential and similar reservoir research.
