| titleOfInvention | A kind of synthetic method of slippery water drag reducer |
| abstract | The present invention relates to oilfield horizontal well group fracturing technique field, the synthetic method of more particularly to a kind of efficient slippery water drag reducer of low molecule amount.This method step is as follows：First, after being cleaned up in reactor, deionized water is poured into according to production, acrylamide, acrylic acid, sodium hydroxide and sodium vinyl sulfonate are poured into reactor successively, every kind of material pours into another again after being completely dissolved, solution in reactor is well mixed, now total solution quality is A in reactor.It is soluble in water that the present invention realizes slippery water drag reducer, drag-reduction effect is good, reduces liquid line flowing frictional resistance positive effect, does not block oil gas output passage, reservoir is not damaged after pressure, salt resistance anti-shear ability is strong, prepares simple, environmental protection, it can be recycled, use cost is low, has preferable versatility, and the resources such as the shale oil-gas reservoir larger to potential reserve and tight sand oil-gas reservoir that are particularly suitable for use in carry out pressing crack construction exploitation. |
