Low-density ceramsite proppant and preparation method thereof
The invention belongs to the field of petroleum and natural gas extraction, and particularly relates to a low-density ceramsite proppant and a preparation method thereof. The preparation method comprises the following steps: S1, carrying out high-temperature calcination on the oily sludge dry residue for later use; s2, mixing the oily sludge dry slag subjected to high-temperature calcination with titanium-containing blast furnace slag to obtain a mixture; and S3, crushing and granulating the mixture obtained in the step S2, sintering in a rotary kiln, and transferring into a cooling device for shock cooling to obtain the low-density ceramsite proppant. According to the preparation method of the low-density ceramsite proppant, the oily sludge dry slag and the titanium-containing blast furnace slag are used as raw materials to prepare the low-density ceramsite proppant, other materials are not doped, waste recycling is achieved, and the requirement for bauxite resources in preparation of the low-density ceramsite proppant is lowered. In addition, the titanium-containing blast furnace slag is adopted to provide titanium as a condensation core formed by microcrystals, and the crystallization time is shortened, so that the time required by sintering is greatly shortened, and the sintering cost is reduced.
本发明属于石油、天然气开采领域,具体涉及一种低密度陶粒支撑剂及其制备方法。本发明的制备方法包括以下步骤:S1、将油污泥干渣进行高温煅烧,备用;S2、将高温煅烧后的油污泥干渣与含钛高炉渣混合,获得混合物;S3、对步骤S2获得的混合物进行粉碎、造粒,之后在回转窑内烧结,然后转入冷却装置中骤冷,制得所述的低密度陶粒支撑剂。所述低密度陶粒支撑剂的制备方法以油污泥干渣与含钛高炉渣为原料制备低密度陶粒支撑剂,不掺入其它物料,既实现了废物再利用,又降低了制备低密度陶粒支撑剂对铝矾土资源的需求。此外,本发明采用含钛高炉渣提供钛作为微晶体形成的凝结核心,缩短结晶时间,从而大幅降低了烧结所需要的时间,降低了烧结成本。
