Factors influencing hydrogen peroxide decomposition dynamics for thermochemical treatment of bottomhole zone

Abstract Recently, interest in on-site heat generation has increased due to injection of thermochemical fluids as a complex effect on well productivity. The method treatment with H 2 O while restoring and increasing the filtration characteristics bottomhole formation zone is relatively new insufficiently studied technology. article discusses key factors affecting exothermic decomposition this fluid when injected into well. effects, pressure growth time were determined depending salinity water, composition terrigenous rock, various concentrations . Physical 1-D modeling was carried out rock models mobile stationary oil, which demonstrated sharp increase temperature by 100–240 °C caused catalyst presence catalytic active sites rock. As result treatment, partially cleaned immobile oil heavy sediments. Injection shown effectiveness displacement from filled sand model. Thus, results study can provide preliminary assessment fields operated at later stage development.
