| titleOfInvention | A kind of preparation method of Oil/gas Well extremely-low density fracturing propping agents |
| abstract | The preparation method that the invention discloses a kind of Oil/gas Well extremely-low density fracturing propping agents。1) silicon ash is scattered in organic solvent, be heated to 80-95 DEG C add silane coupler reaction 1-3h, then cool to 50-65 DEG C add organic acid reaction 1-3h, cooling, sucking filtration, dry obtain modified silicon ash；Modified silicon ash is joined the methyl methacrylate monomer mixed liquor dissolved with cross-linking agent and initiator, with water for dispersant, adds suspending agent, synthesize complex microsphere by suspension polymerisation, filter, wash, dry, cross 15-60 mesh sieve and obtain density at 1.119g/cm 3 ～1.278g/cm 3 Fracturing propping agents。Density is close to water, in oil exploitation, it is possible to be load fluid with tap water or saline, such that it is able to pressing crack construction cost is greatly reduced, and energy-saving and emission-reduction, it is to avoid use the pluronic polymers such as guar gum, reduce the pollution to environment, improve economic benefit。 |
