低密高强压裂支撑剂的研究
Research on the low density and high strength of the proppant
摘要
Abstract
The low density and high strength proppants were fabricated from coal gangue and flyash as main raw materials and TiO2 +ZnO+ CaMg[CO3 ]2 as composite mineralizers .By optimizing raw materrials proportions and processing parameters ,w hile exploring the prepa-ration conditions and law of impact ,the proppants with low density and high strength were successfully fabricated at sintering temperature of 1 330 ℃ ~1 370 ℃ .The bulk density of the proppant is 1 .54 g/cm3 ,w hile failure rate of the proppant under 69 M Pa closure stress is 3% ~5% .The crystal phase and microstructure of the proppants were investigated by XRD and SEM .关键词
