Ceramsite sand for oil field
The invention relates to ceramsite sand for an oil field, the ceramsite sand comprises aggregate and a shell material wrapping the outer surface of the aggregate, and the mass ratio of the shell material to the aggregate is 1: (2-7); the aggregate comprises the following components in parts by weight: 15-30 parts of a matrix, 5-8 parts of white carbon black and 4-5 parts of starch; and uniformly mixing the aggregate and the shell material, stirring at the constant temperature of 50 DEG C, drying and curing to obtain the ceramsite sand. The ceramsite sand comprises aggregate and a shell material, the shell material is a high-molecular compound, the volume density of the ceramsite sand is reduced to a certain extent due to the addition of the shell material, the aggregate comprises ceramsite, molding sand, white carbon black, starch and other materials, and due to the addition of the white carbon black, on one hand, the mechanical strength of the ceramsite sand can be improved; on the other hand, the volume density of the ceramsite sand can be reduced to a certain extent; the starch added into the aggregate can form a porous material under high-temperature calcination, so that the volume density of the ceramsite sand is further reduced to a certain extent.
本发明涉及一种油田用陶粒砂，该陶粒砂包括骨料和包裹在骨料外表面的壳料，壳料与骨料的质量比例为1:(2‑7)；按照重量份数计，所述的骨料包括以下组分：15‑30份基体、5‑8份白炭黑、4‑5份淀粉；将所述的骨料与壳料混合均匀，并恒温在50℃下搅拌，经过烘干、固化即得陶粒砂。该陶粒砂包括骨料和壳料，壳料为高分子化合物，壳料的加入在一定程度上降低了该陶粒砂的体积密度，而骨料则包括陶粒、型砂、白炭黑和淀粉等材料，白炭黑的加入一方面能够提高陶粒砂的机械强度，另一方面也能够在一定程度上降低陶粒砂的体积密度；骨料中所加入的淀粉在高温煅烧下会形成多孔材料，从而在一定程度上进一步降低了陶粒砂的体积密度。
