Auto-suspension propping agent

The invention belongs to the technical field of mining of fluid ore of oil, natural gas, shale gas and the like, and particularly discloses an auto-suspension propping agent. The auto-suspension propping agent is prepared from aggregate and a covering layer, wherein the covering layer is prepared from resin, a curing agent and an additive, the aggregate is ceramsite with apparent density of 1.05-2.65 g/cm3, and the additive is an amine compound. The auto-suspension propping agent is mainly used for mining oil and shale gas, and the problem that when a propping agent is used in clear water, a gelatinizing agent needs to be added so that cost improvement and environmental pollution are caused is solved. 本发明申请属于石油、天然气及页岩气等流体矿产开采技术领域，具体公开了种自悬浮支撑剂，包括骨料和涂覆层，所述涂覆层包括树脂、固化剂和添加剂，所述骨料为视密度1.05～2.65g/cm的陶粒，所述添加剂为胺类化合物。本发明主要用于开采石油、页岩气，解决了支撑剂在清水中使用需要添加胶凝剂导致成本增高和造成环境污染的问题。
