| Abstract: | Free formaldehyde content in resin is reduced through beetle modification, and the toxicity is thus reduced. The toughness of resin has been increased after adding modifier. When using beetle for sand control, the cost is low, surface viscosity is low, pumpability is good, operation is simple, and both the strength and permeability after sand consolidation are high. It has achieved good field application result. |
