简介:研究表明,川西地区沙溪庙组储层主要储集岩为长石砂岩、岩屑长石砂岩,其次为岩屑砂岩、长石岩屑砂岩及岩屑石英砂岩。储集空间分为孔、缝,其中主要储集空间为粒间溶孔,其次为残余粒间孔和粒内溶孔。喉道类型以管状和粒间裂隙为主,属细一微喉型。储层孔隙结构差,具有孔隙小、喉道窄、有效连通孔隙体积小和中一高排驱压力的特征,总体属于低一中孔、低一中渗,局部存在高孔高渗的常规储层,非均质性强。在此基础上通过对储层发育控制因素、储集砂体展布及有利储集区带的研究,为川西沙溪庙组的油气藏勘探开发提供了重要支撑。图10表2参4

简介:在这份报纸,环境扫描电子显微镜学(ESEM)被用于描绘矿物质和处理残余(COPR)的铬铁矿矿石的元素分发。测试结果证明忍受Crbrownmillerite发生在COPR粒子的边界,当有在它的结构的Cr(VI)的hydroandradite在内介绍COPR粒子时。方镁石和方解石发生在空隙的区域。Ca,Fe和艾尔在整个COPR粒子是分布式的元素分析表演,和Mg主要在空隙的区域或在粒子表面上存在。Cr的一个更低的内容在COPR粒子是均匀地分布式的,当Cr的稍微更高的集中发生在粒子内时。让Cr从COPR移居将花一相对更长的时间,这被建议,特别为hexavalent铬,因此沥滤的时间和粒子尺寸可以是影响Cr(VI)的版本的二个重要因素。
