Abstract:To improve the thermal effects of solvents on heavy oil reservoirs and realize the combined action of multiple flooding mechanisms, such as solvent heating and extraction, without steam mixing, based on the M Block heavy oil reservoir in Canada, three sets of comparative hot solvent-assisted gravity drainage experiments under different temperatures and pressures were carried out through an indoor three-dimensional (3D) physical simulation device. The development characteristics of the solvent chamber in the ho… Show more
“…MicroXRF spectrometry is widely used in geological studies as it provides valuable information for sediments. MicroXRF spectrometry was 36 a powerful tool for interpreting the genesis of dolomitisation as it can be used to visualise the elemental distribution over a large area thereby to identify delicate genetic characteristics. Single point 10 s measurements gave a high level of accuracy (97–103% and a SD of <3%) for Ca, Fe and Mg. A 300 ms exposure time for each sampling point in a scan made it possible to study the enrichment and depletion of Mg and other elements.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
