Abstract

​

The effectiveness of a number of methods for removing asphaltene-resin-paraffin deposits from the surface of the downhole equipment depends on the properties of the asphaltene-resin-paraffin deposits and the properties of the composition and structure of the deposits, the intermolecular adhesion forces and the adhesion to the surface that determine these properties. In this regard, the study of the physicochemical properties of paraffin deposits is of practical interest.

The paper presents the results of an analysis of the properties of field samples of paraffin in order to clarify the optimal composition of the sediment solvent composition. The nature of the influence of moisture saturation on the mechanical strength index of field samples of sphaltene-resin-paraffin depositss is established, in which a trend towards a decrease with increasing moisture saturation can be distinguished. The high heterogeneity of the mechanical properties of paraffin deposits is shown, which justifies the need for individual selection of compositions for a well or group of wells, as well as the processing time when using solvent compositions.

Key words:

​

asphaltene-resin-paraffin deposits, mechanical strength, moisture saturation, sucker rods, efficiency
