| Summary: | Article deals with problems of oil production on Kazakhstan`s fields. The necessity of search for more effective ways of restoring the initial permeability of bottomhole zone of the formation was established. The assessment is given to methods of removal and decrease in asphaltic-resinous and paraffin deposits in a bottomhole zone of oil layer. A new technology of treating the bottomhole zone of a layer with oil-based solvents is offered and ways of increasing well flowrates are considered. Experimental studies have been carried out to determine the ability of the recommended new oil reagents to dissolve asphaltic-resinous, paraffin deposits. The conclusion was made that new petroleum solvents differ from others not only in high efficiency but also in low cost and affordability, as they can be obtained with simple equipment directly from the degassed oil in field conditions.
