Investigation on the low temperature oxidation of light oil for safely enhancing oil recovery at high temperatures and pressures

Research on Evaluation of Corrosion Inhibitors for Oxygen Reducing Air Drive Gas Wells

“…Multiple adsorption centers (such as N, O and other elements) in the main product molecules of corrosion inhibitors provide lone pair electrons to the metal surface, forming coordination bond compounds that adsorb on the bare metal surface without an oxide film; Then, the non-polar groups (thiourea and rosin groups) in the molecule are laid flat on the metal surface, forming a relatively complete hydrophobic protective layer, forming a barrier between the metal and preventing the diffusion of corrosion products such as iron ions into the solution and the migration of H + into the metal during the corrosion reaction process, slowing down the corrosion reaction speed and achieving the goal of metal corrosion inhibition. The corrosion inhibition mechanism of such inhibitors is also a "negative catalytic" effect [9][10][11]. After the addition of corrosion inhibitor No.…”

Maximizing enhanced oil recovery via oxidative cracking of crude oil: employing air injection and H2O2 with response surface methodology optimization

“…However, as the temperature increases from 340 to 360 °C, there is a notable increase in the yield. This is attributed to the intensified molecular movements and the averaging of local magnetic fields, leading to increased molecular mobility [46]. The highest design temperature of the reactor was approximately 360 °C, resulting in a maximum liquid fraction of over 96 vol.…”
