More Information
Summary:The invention provides an authigenic carbon dioxide fracturing propping agent, which is characterized in that a carbon dioxide authigenic agent is wrapped outside an inner core, and a moisture-proof adhesive is wrapped outside the carbon dioxide authigenic agent. The invention further provides a preparation method of the authigenic carbon dioxide fracturing propping agent. The preparation method comprises the following steps: S001, fully mixing the organic acid with the sodium carbonate, the sodium bicarbonate and the ethanol adhesive to obtain the carbon dioxide authigenic agent; S002, preparing a curing agent; S003, preparing an additive; S004, firstly mixing the heated quartz sand or ceramsite with an additive, then adding a carbon dioxide autogenous agent for mixing, finally adding a curing agent for mixing and stirring, and then cooling, crushing and screening a product to obtain middle-layer precoated sand; S005, mixing the heated middle-layer precoated sand with an additive, then adding a damp-proof bi
