Abstract

The coal expansibility, wettability, adsorption, surface tension, damage, adsorption and desorption experiments of cationic surfactant, nonionic surfactant and anionic surfactant were performed to investigate the effect of surfactants on hydraulic fracturing in coal bed methane (CBM) reservoir. The expansion height, contact angle, adsorption forms and absorbance, the surface tension and permeability of coal samples before and after damage, adsorption and desorption of different surfactants and compounded systems were compared and analyzed to identify the optimal system. The investigation shows that the surfactants and water have little effect on coal expansibility. The cationic surfactant increases the coal sample's hydrophobicity, the nonionic surfactant maintains the coal wettability, and the anionic surfactant increases the coal hydrophilia. The nonionic surfactant enlarges coal porosity and accelerates coal gas desorption. The GM is dot adsorption, OP is tile adsorption, and 1831 is conjoined structure adsorption. The GMOP-4 compounded system with low surface tension significantly decreases the GM adsorption volume and accelerates coal gas desorption. The GMOP-4 compounded system realizes the low-cost and high-performance application of cationic surfactants in CBM hydraulic fracturing.
