摘要:
运用偏光显微镜、X衍射、扫描电镜等分析测试技术,对鄂尔多斯盆地西部长8储层砂岩胶结物类型及特征进行研究,结果表明:研究区粘土胶结物以伊利石、高岭石、绿泥石和伊蒙间层矿物为主,其相对含量分别为20.11%～42.19%、18.13%～32.51%、23.84%～62.72%、1.86%～25.10%。由于岩石中含有较多的富铁凝灰质,大部分在沉积成岩环境中绿泥石化,这类物质在进入沉积水域之后发生了强烈的水化作用并析出大量的铁氧化物,从而形成了对粘土矿物的侵染,说明沉积环境Eh值比较高,沉积—早成岩早期环境相对比较开放,大量三八面体绿泥石的出现反映了早成岩中晚期强烈的还原环境。碳酸盐类胶结物以方解石为主,其次为铁白云石和菱铁矿。C/O同位素分析表明,碳酸盐胶结在本区贯穿于整个成岩期。普通方解石一般形成于成岩早期,铁方解石和铁白云石形成于成岩中、晚期。
Abstract:
By using polarizing microscope,scanning electron microscopy and X-ray diffraction,it was carried out the characteristics and type of the cements in Chang8 reservoir in western Ordos Basin.Results showed that clay minerals were mainly composed of illite,kaolinite,chlorite and illite/montmorillonite interstratified minerals with the relative contents of from 20.11% to 42.19%,from 18.13% to 32.51%,from 23.84% to 62.72%,and from 1.86% to 25.10%.Due to the chloritization of some Fe-rich tuffs in the sedimentary and diagenetic environment,after these kind materials entered the sedimentary water,strong hydration occurred and a large number of iron oxides were precipitated.Thus this led to the contamination of clay minerals.This phenomenon showed that Eh value was high and the sedimentic -diagentic environment was open.A large number of trioctahedron chlorite reflected a strong reductive environment at the mid-advanced stage of early diagenesis.The carbonate cement was mainly composed of calcite,second for ankerite and siderite.The isotope analysis of carbon and oxygen showed that carbonate cementation ran through the whole diagenesis.Calcite was formed at the early stage of diagenesis and the ferrocalcite and ankerite were formed at the middle or late stage of diagenesis.
