A new regent on the basis of activated aluminum Rau-85 was suggested for thermal gaseous chemical treatment of bottom hole formation zone of oil wells. Experimental research of studying Rau-85 effect on oil saturated cores was carried out. By modeling formation conditions, thermal gaseous chemical treatment of oil saturated Uaz oilfield natural cores of terrigenous rock was handled. Filtration-volume properties of cores were studied. It’s shown that during reaction of activated aluminum with formation fluids, a large amounts of heat, atomic hydrogen and hydrocarbon gases are generated. Group composition analysis of the oil before and after thermal gaseous chemical treatment by reagent Rau-85 was conducted. We observed a decrease in the content of hydrocarbons from C33 to C40 by 2.83% and an increase of light hydrocarbons ranging from C11 to C32 by 10.74% in the oil composition. This evidences that hydrogenolysis of oil by atomic hydrogen is occurred directly in the core.

It’s implemented a comparison of oil displacement efficiency from core by gases generated during thermal gaseous chemical treatment by reagent Rau-85 and the displacement of water.

Based on the results of a laboratory experiment the displacement of formation water and heavy oil thermal gaseous chemical influence by reagent Rau-85 in the oil-saturated core, we can conclude about the prospects of the use of activated aluminum alloys Rau-85 for bottom hole formation zone treatment to enhance oil recovery.
