Based on theories of grains size and dense packing,our research took oil-well cement with high-resistance to sulfur,Jiahua G,and hematite as basic materials and prepared a kind of cement slurry with density varying from 2.
文章以粒级级配和紧密堆积原理为理论依据,以嘉华G级高抗硫油井水泥和赤铁矿等为基本原料,通过复配不同颗粒大小的赤铁矿配制密度为2·2g/cm3~2·3g/cm3水泥浆。
