Low-density fly ash fracturing propping agent and preparation method thereof
The invention belongs to the technical field of inorganic materials, and particularly relates to a low-density fly ash fracturing propping agent and a preparation method thereof. Raw materials and components used in the invention are as follows: 100 parts of fly ash, 1-15 parts of an adhesive, 1-10 parts of a fluxing agent, 0.5-8 parts of a reinforcing agent and 0-0.5 parts of a water reducing agent. The preparation method comprises the following steps: ball-milling, mixing, granulating, shaping, drying, sintering, cooling and screening. The raw materials are granulated below 75 microns and shaped below 40 microns, so that the volume density of the proppant is reduced, and the sphericity is improved; due to the introduction of the additive, the fracturing propping agent obtains proper strength and toughness. According to the invention, a large amount of fly ash is utilized, a good way is found for environmental protection and resource utilization of solid wastes, and the low-density fly ash fracturing propping agent is prepared at the same time.
本发明属于无机材料技术领域，具体涉及一种低密度粉煤灰压裂支撑剂及其制备方法。所用原料及组分为：粉煤灰100份，粘接剂1～15份，助熔剂1～10份，增强剂0.5～8份，减水剂0～0.5份。制备方法为，球磨、混合、造粒、整形、干燥、烧结、降温，筛分后制得。原料选用75μm以下造粒，选用40μm以下整形，降低支撑剂体积密度，提高球度；外加剂的引入使压裂支撑剂获得适宜的强度和韧性。本发明大量的利用粉煤灰，对环境保护、固体废弃物的资源化利用找到一条很好出路，同时制备出一种低密度粉煤灰压裂支撑剂。
