Embodiment 1
[0043] This embodiment provides a fire flooding chemical ignition combustion accelerant, including A component and B component;
[0044] A component includes: carbon powder and iron acetylacetonate; B component includes: carbon powder, sulfur, magnesium aluminum powder (mixed in conventional proportions);
[0045] In terms of mass percentage, the dosage ratio of each component is respectively: 60% of iron acetylacetonate, 15% of carbon powder, 15% of magnesium aluminum powder and 10% of sulfur.
[0046] Above-mentioned fire flooding chemical ignition combustion accelerant is prepared like this:
[0047] Grind the raw materials of component A and component B to a fineness of more than 200 mesh (pass through a 200 mesh sieve), mix them separately (mechanical mixing according to conventional methods), and obtain component A powder and component B powder;
[0048] Use the extrusion method to granulate the powder of component A and powder of component B respectively, with a partic...
