苏里格气田辫状河沉积相研究及其在地质建模中的应用

Study on sedimentary facies of braided stream and its application in geological modeling in Sulige gas field

  • 摘要: 根据岩心、测井、地震等资料,在单砂层划分对比的基础上,对苏里格气田主要目的层段盒8-山1沉积砂体进行分析,认为研究区主要是沼泽背景下的辫状河沉积体系。分析认为,辫状河沉积可划分为河道沉积和岸外沉积两个亚相,其中河道沉积亚相可细分为心滩、河道冲填和废弃河道微相,岸外沉积可细分为堤岸沉积、溢岸洼地砂等微相。在此基础上,对沉积微相与有效储层的关系进行了分析,并将研究结果成功地应用到储层地质建模中。

     

    Abstract: On the basis of classification and correlation of single sandstone horizon according to bore cores,logging and seis- mic data,analysis on target horizons——the eighth member of Shihezi Formation to the first member of Shanxi Forma- tion member in Sulige gas field suggests that the region stud- ied is of the is mainly the sedimentary system of braided stream under the background of marsh.It is presented that the braided stream can be divided into channel subfacie and off-coast subfacies,of which the stream chanel subfacies can be subdivided into the microfacies of diara,stream chan- nel sluicing and discarded stream channel,and the off-coast subfacies can be subdivided into the microfacies of bank sedi- mentation,and bank-spilled trough sandstone.The rela- tionship between the sedimentary subfacies and effective res- ervoir is performed thereby,and the research production is successfully applied into the geological modeling of reser- voir.
