Abstract


For fluid transportation of natural gas and oil pipeline hydrate the wellbore, pipelines, valves and equipment to plug the problem, in order to ensure the safe flow of hydrates in the transportation process, the laboratory using various methods of research hydrate inhibitors and anti-poly agent, the future trend visualization is becoming more and more and more microscopic study. Inverted microscope for major equipment, the establishment of the first set for hydrate inhibitors and anti-polymerization inhibitor micromanipulation and imaging systems. Of tetrahydrofuran (THF) and tetrabutylammonium bromide (TBAB) the size of the hydrate of crystal growth, and the hydrate particles adhesion and impact factors. Established the the microscope operating and imaging system the inverted microscope Carl Zeiss Axio Observer.A1 main. Including image acquisition and processing system; temperature measurement and control system; hydrate low temperature reaction system. The TBAB hydrate and THF hydrate morphology was observed using micromanipulation and imaging systems 9 ° C, the mass fraction of 40% TBAB hydrate crystals formed into tetrahedral, hexahedral and octahedral growth rate 0.26um / s while observing THF hydrate crystals at 1 ° C, -1 ° C and -2 ℃ under the growth condition, and to add the PVP and the graphene, THF's crystal growth was found to destroy the crystal structure of the THF PVP, inhibit hydrate Growth, and 10ppm graphene was able to promote the growth of the hydrate. Were measured and the adhesion between the size the TBAB and THF hydrate particles, such as to a diameter of wire of 0.1 mm as the cantilever material, the formation of the TBAB hydrate particle diameter is 650 to 730um, the contact in 278.35K, 48? N force 10min contact time, the adhesion of the of the TBAB particles isooctane medium approximately 7E-5N, and found that the adhesion between the particles of the TBAB hydrate with a contact time of the logarithm of the linear relationship, the adhesive force size and the contact force, the larger the contact force, the greater the adhesion; the higher the temperature, the greater the adhesion between the particles. While the size of the adhesion of THF hydrate particles and under the conditions of the additive PVP and PVA, the adhesive force changes in the size, experimental results show that there is no effect of anti-poly PVP to hydrate, the PVA was able to reduce THF hydrate The adhesion, the adhesion size can be from 0.03 N / m dropped 0.005N / m, has a good effect of anti-poly PVP anti poly optimal concentration of 0.16% mass fraction.
