准噶尔盆地西北缘八二区三叠系克下组沉积相研究
|
摘要
依据沉积学基本理论和方法,综合运用露头、钻/测井及地震资料,对准噶尔盆地西北缘克百地区八二区三叠系克下组进行了沉积相研究.统计了西北缘八二区84口井克下组砂体厚度和砂砾岩含量,在此基础上编制了克下组S7和S6砂组的砂砾岩等厚图和砂砾岩含量等值线图,结合取心井岩心观察,编制了相应的沉积相平面展布图.通过本次研究认为,S7砂组是克下组砂体最发育的层位,也是最主要的勘探目的层.工区主要有2个物源方向,即西北方向和正北方向,均受南白碱滩断裂控制.研究区克下组主要发育的沉积相类型为辫状河、辫状河三角洲和湖泊.
A precious sedimentary facies analysis of the Lower Karamay Formation of the Triassic in Ba’er Zone of Northeastern Junggar Basin has been done based on the basic principles and research methods of sedimentology and used thoroughly outcrops, drilling, logging and seismic data. The sand bodies thickness and sand percentage of eighty-four wells were statisted in the Ra’er Zone.The isopach maps of sand bodies and sand percentage were drawn.The sedimentary facies maps were also drawn with the core observation.S7 sand group is the most developmental sand body horizon of the Lower Karamay formation and the most important expioration target.The main two provenances that were controlled by Southern Bai Jian tan fault are the directions of northwestern and northern. The main sedimentary facies are braided river, braided river and lacustrine.
