【摘要】：储层构型表征是开发后期挖潜剩余油的重要手段,辫状河砂体是重要的油气储层,但由于辫状河沉积机制复杂,砂体叠置关系多样,致使其内部构型模式复杂。针对辫状河储层构型的研究,在野外地质解剖、测井曲线识别、探地雷达分析以及室内模拟实验等多方面均已取得了诸多研究成果。依据储层构型层次界面分析法,辫状河储层构型共划分出6级储层构型单元;其中主要的储层构型研究对象为3级和4级储层构型单元,研究内容为辫状河沉积体系中单砂体的沉积模式、构型参数表征,心滩内部增生体与夹层的发育模式及构型参数特征。辫状河储层构型主要受构造运动、河水能量、气候条件以及沉积基准面变化4个方面的影响。
[Abstract]:Reservoir architecture characterization is an important means of late development of tapping the potential of residual oil, braided river sand is an important reservoir of oil and gas, but because the braided river sedimentary mechanism complex, sandbody superimposition relationship diversity, resulting in the internal configuration mode. According to the study of complex configuration of braided river reservoir, the opposition foreign matter anatomy identification, logging curve, GPR analysis and indoor simulation experiment and other aspects have made a lot of research results. Based on the interface of reservoir structure AHP, braided river reservoirs like configuration is divided into 6 reservoir architecture unit; the reservoir configuration of the main object of study is 3 level and 4 level storage configuration unit, research content for the single sand body sedimentary model of braided river sedimentary system, configuration characterization, development characteristics of model and configuration parameters of internal body and hyperplasia of the heart beach dissection. The braided river reservoir structure is mainly affected by tectonic movement, the energy and climate. The influence of 4 aspects of the change of the part and the change of the sedimentary base surface.

【正文快照】： 储层构型研究主要依据地质学家Maill针对河流相储层提出的构型理论[1-2]。自该理论提出以来,中外诸多地质学家针对不同类型的沉积体系进行储层构型分析,对于河流相储层,地质学家们对曲流河储层构型的研究程度较高,例如在储层构型划分、点坝构型解剖、储层构型参数地质知识库建
