| titleOfInvention | Wood tar resin sand consolidation agent and preparation method and application thereof |
| abstract | The invention discloses a wood tar resin sand consolidation agent, which comprises the following raw materials in parts by weight: 60-80 parts of wood tar prepolymer, 4-15 parts of curing agent, 2-10 parts of reinforcing agent and 10-30 parts of diluent; the wood tar prepolymer is a product obtained by polycondensation of a wood tar extract and aldehydes under the action of an acid catalyst. The wood tar prepolymer has good temperature resistance, is crosslinked with the curing agent to form a reticular macromolecule, improves the compressive strength of the wood tar resin sand consolidation agent, and organically combines the formation sand and the wood tar prepolymer together by the reinforcing agent, improves the consolidation performance of the wood tar resin sand consolidation agent; the added diluent can improve the fluidity of the wood tar on one hand and is beneficial to being injected into a shaft; on the other hand, the permeability of the consolidation body can be increased, and the thick oil extraction is facilitated. The invention also provides a preparation method and application of the wood tar resin sand consolidation agent. |
