摘要

ZG气田位于印度尼西亚苏门达腊盆地,断块复杂,发育多种沉积相体系类型。基于沉积背景和碎屑岩储层类型,利用测井沉积相研究方法,选取自然伽马、自然电位、电阻率、密度测井曲线作为研究区测井沉积相研究的测井系列,结合岩心、录井、地震等资料,综合层序地层学等多学科,建立取心井段测井相岩-电转换模版,识别出ZG气田Lumut段发育扇三角洲、辫状河三角洲和湖泊3种沉积相类型,建立了各沉积相测井微相特征图版。研究认为,Lower Lumut层为扇三角洲—辫状河三角洲—湖泊沉积体系,Middle Lumut层为辫状河三角洲—浅湖沉积体系,Upper Lumut层为辫状河三角洲前缘—浅湖沉积体系,其中辫状河三角洲分流河道砂体为有利储层。
ZG Gas Field is located in Sumatra Basin of Indonesia with complex segments and multiple of depositional systems.Based on the background of deposition and clastic reservoir type,logging sedimentary facies study method is used toidentifydeposition facies byanalyzingthe characteristics oflogseries includingGR,SP,RLLDand DEN,combined with core,master log,seismic data,sequence stratigraphy,etc.The rocks-electrical switching models of core phase are established.Fan delta,braided delta and lake deposition facies are identified and different logging microfacies characters models of depositional facies are obtained.Analyzed and recognized fan delta-braided delta-lake depositional system was developed in Lower Lumut zone,braided delta-lake depositional system was developed in Middle Lumut zone and delta front-shallow lake depositional system braided was developed in Upper Lumut zone by studying characters of microfacies distribution.Braided delta distributarychannel sand bodyis favorable reservoir.
