备注

隔夹层是储层非均质性研究的主要指标,隔夹层在三维空间的展布,对油气勘察预测、储层开发研究、提高原油采收率都有重要的作用。以具体研究区块为例,结合测井分析、沉积相研究、储层特征分析等,对黄陵地区长63储层的隔夹层进行了研究,总结了隔夹层的成因、特征与识别方法,对隔夹层的平面展布特征完成了定量分析,结合研究区块勘探开发现状,将隔夹层特征与储层研究相结合,阐述了隔夹层对储层作用的双重性特征,为浊积岩储层开发提供了参照。

The interlayer is an important index for study of reservoir heterogeneity.The interlayer in the three-dimensional space distribution has an important role in the oil and gas exploration prediction,study of reservoir development,and enhance of oil recovery.Taking the specific research area as example,combining well logging analysis,sedimentary facies study and reservioir characteristic analysis to complete the quantitative analysis on the plane distribution of interlayer.Based on the research situation on exploration and development,and integration of the interlayer characteristics and reservoir research,analyses and describes the double features of interlayer on the reservoir effect,providing a reference for the turbidite reservoir development.
