在松散岩层中,像砾岩或强烈破碎的岩层中,采用橡皮套,可以紧紧地抓住岩芯,可以保护岩芯免受冲洗液冲刷,避免堵塞或遭受研磨,使岩芯保持原状。这样,便于携带、分析和运输(图1)。橡皮套直径比岩芯直径小些。这可使套住的岩芯连续被抓紧,防上弄碎或错开。这 In loose rock formations, such as conglomerates or heavily crushed rock formations, a rubber boot can be used to hold the core tightly to protect the core from washout and to prevent clogging or grinding and to keep the core intact. This makes it easy to carry, analyze and transport (Figure 1). Rubber sleeve diameter smaller than the core diameter. This allows the trapped core to be continuously gripped, prevented from breaking or staggering. This
