黄骅盆地下第三系砂岩成岩作用的扫描电镜研究
SCANNING ELECTRON MICROSCOPE STUDIES ON DIAGENESIS OF EOGENE SANDSTONES OF HUANGHUA BASIN
-
摘要: 本文研究的样品是大港油田地质研究所选出的十套典型岩心标本(十口井共计543米岩心),是黄骅盆地下第三系中常见的一些砂体类型,时代从渐新世早期到渐新世晚期,还包括了上第三纪馆陶组地层。本区下第三系含油砂岩的陆源碎屑中石英含量一般不高,在50%以下。长石含量较高,有的可达45%左右,以斜长石和正长石为主.微斜长石较少。岩屑含量除个别井段较高外,一般在25%以下,以火山岩岩屑为主,沉积岩和变质岩岩屑很少。Abstract: Huanghua Basin, an important oil-bearing basin in eastern China, is one of the Mesozoic and Cenozoic fault-subsidence basins.
