Ignition is one of the most important techniques used to ignite crude oil during the in-situ combustion process. However, one problem with this process is that the ignition time is long. To address this problem, this study provides a solution by using a thermal insulation structure consisting of three layers placed inside an electric heater. To investigate the performance of the thermal insulation...
With the purpose of researching on the influence of CO2 injection tubing with corrosion defects to the safety production of CO2-EOR flooding, experimental tests and finite element simulations were conducted to analyze the failure pressure and stress distribution of P110 pipe with single point corrosion, axial line corrosion and uniform corrosion defects. Metallographic examination was also done to...
A series of a novel shape-stabilized phase change material of poly(hexadecyl acrylate)/graphene oxide (PHDA/GO) nanocomposite was fabricated by in situ free radical polymerization. The fabricated PHDA/GO nanocomposites mainly contain a poly(hexadecyl acrylate)-grated-graphene oxide (PHDA-g-GO) solid-solid phase change material (SSPCM) and a PHDA solid-liquid phase change material (SLPCM). The PHDA-g-GO...
