    • A method is disclosed for low damage gravel packing. The method includes combining a carrier fluid, a first amount of particulates, and a second amount of particulates into a slurry. The first amount of particulates have a first average size distribution and the second amount of particulates have a second average size distribution, and the first average size distribution is at least three times larger than the second average size distribution. The slurry includes particles which are at least partially degradable material, and with reactive solid constituents. The reactive solid reacts with the degradable material and/or a hydrolysis product of the degradable material. The method further includes positioning a screen in a wellbore, and circulating the slurry through the wellbore such that the first amount of particulates and the second amount of particulates are deposited on an outer surface of the screen.
    • 公开了一种低损伤砾石包装的方法。 该方法包括将载体流体,第一量的微粒和第二量的微粒组合成浆料。 第一量的颗粒具有第一平均尺寸分​​布,第二量的颗粒具有第二平均尺寸分​​布,并且第一平均尺寸分​​布比第二平均尺寸分​​布大至少三倍。 浆料包括至少部分可降解材料的颗粒和具有反应性固体成分的颗粒。 反应性固体与可降解材料和/或可降解材料的水解产物反应。 该方法还包括将筛网定位在井眼中,并使浆料循环通过井眼,使得第一量的微粒和第二量的微粒沉积在筛网的外表面上。
