Fracturing propping agent composition, fracturing propping agent as well as preparation method and application of fracturing propping agent
The invention relates to the field of fracturing propping agent preparation, in particular to a fracturing propping agent composition, a fracturing propping agent as well as a preparation method of the fracturing propping agent. The invention relates to a fracturing propping agent composition. The fracturing propping agent composition comprises fly ash, metakaolin and an optional binder, wherein on the basis of the weight of the fly ash, the fly ash contains 35 wt% or above of Al2O3, 25 wt% or above of SiO2, 8 wt% or less of CaO and 1 wt% or less of M2O; on the basis of the weight of the metakaolin, the metakaolin contains 35 wt% or above of Al2O3, 25 wt% or above of SiO2, 8 wt% or less of CaO and 1 wt% or less of M2O, and M is Na and/or K element; and the binder is water and/or an organic binder. The fracturing propping agent prepared by using the fracturing propping agent composition disclosed by the invention through the method disclosed by the invention has relatively high strength, relatively low breakage rate and relatively low density.
本发明涉及压裂支撑剂制备领域，具体涉及压裂支撑剂组合物、压裂支撑剂及其制备方法。一种压裂支撑剂组合物，所述组合物包含粉煤灰、偏高岭土以及可选的粘结剂；以所述粉煤灰的重量为基准，所述粉煤灰含有35重量％以上的Al2O3，25％重量以上的SiO2，8重量％以下的CaO，1重量％以下的M2O；以所述偏高岭土的重量为基准，所述偏高岭土含有35重量％以上的Al2O3，25％重量以上的SiO2，8重量％以下的CaO，1重量％以下的M2O，其中，M为Na和/或K元素；所述粘结剂为水和/或有机粘结剂。使用本发明所述的压裂支撑剂组合物通过本发明所述方法制得的压裂支撑剂兼具较高的强度、较低的破碎率和较低的密度。
