Rheological,dynamic sand-carrying and drag reduction properties of amphiphilic graphene oxide and hydrophobically modified partially hydrolysed polyacrylamide(HMHPAM)composite fluids
摘要
Abstract
Objective Using the large specific surface area of amphiphilic graphene oxide(SAG)and the interaction of surface amphiphilic modification groups with hydrophobic,hydrogen bonding and other non-covalent bonds of hydrophobically modified partially hydrolysed polyacrylamide(HMHPAM),the study purpose is to modulate rheological properties of composite fluids,especially viscoelasticity at very low SAG additions,and explore new technical paths for designing and developing high viscosity friction reducers with variable viscosity slick water fracturing fluid and sand carrying.Method Preparation of SAG from graphene oxide(GO),sodium 6-amino-4-hydroxy-2-naphthalenesulfonate(ANS)and dodecyltrimethoxysilane(DTMS)as raw materials.The apparent viscosity of SAG/HMHPAM composite fluids and their viscoelasticity were investigated on an advanced rheometer.Dynamic sand carrying properties of composite fluids investigated on own micro-visible slit dynamic sand carrying device.The drag reduction performance of the composite fluid was tested on a friction meter.Result The apparent viscosity and viscoelasticity of the HMHPAM/SAG composite system at very low SAG dosages(5-100 mg/L)were significantly improved relative to the HMHPAM polymer solution.In the range of mass concentrations of associative polymers(HMHPAM)examined(400-1 200 mg/L),adding 5 mg/L and 50 mg/L SAG,composite systems improve proppant transport performance by 6.07%-13.08%and 11.32%-19.16%,respectively.SAG had no negative effect on the drag reduction performance of the composite system.Conclusion The apparent viscosity of the SAG composite system increases,especially the viscoelasticity,which improves the dynamic sand carrying significantly.A new technical path can be provided for constructing a new type of variable viscosity slickwater fracturing fluid with high sand carrying and high drag reduction.关键词
