Key words: asphalt-resin-paraffin deposits, deposits content, structure of paraffin.

In this paper was studied the physicochemical properties and composition of solid paraffin deposits taken fr om wells Uzhno-Kamyshitovoe, Uzen field and paraffin deposits extracted from oil Kumkol and Akshabulak. It was showed that asphalt-resin-paraffin deposits (ARPD) density increasing depends on asphaltenes content. Identified metals and their quantitative composition in ARPD was determined by X-Ray analysis. The structure of extracted paraffin was examined by optical microscope. For confirm the structure and phase contain of paraffin was used X-ray phase analysis. There was found that crystalline phase contain mainly normal paraffin wh ereas isoparaffin and napthenes characterize with amorphous structure. As a result, it was found that the composition and properties of paraffin wax deposition are determined by oil nature, which is particularly important when selecting the most effective ARPD inhibitors.
