A composition of “Difron-4102” depressor additive and С-1+“Difron-4201”=28:1 (code name – AI-1) against paraffin sedimentation was developed for the first time. The decrease of the freezing temperature and surface tension, their effect on a sample of the paraffin oil from Bulla-deniz field was studied in laboratory conditions. It was defined that the composition of AI-1 shows higher effectiveness compared to the “Difron-4102” depressor additive. Thus, in an optimum concentration, when the highest effect is observed, the impact of the additive and composition is equal to 96.3 %, against paraffin sedimentation - 97.8 %, 1.6-2 times by freezing temperature, and 2.1-3.2 by the surface tension as well.
Moreover, the effect of “Difron-4102” depressor additive and redeveloped AI-1 composition on the dynamic viscosity of the oil sample from Bulla-deniz field was studied. It was specified that the dynamic viscosity of the oil decreases as the concentration of the additive and composition increases. The highest drop occurred in an optimum concentration of the agents. Thus, the oil viscosity in 900 g/t additive decreases from 21.6 Pa·s up to 0.9 Pa·s, and in 700 g/t composition – up to 0.3 Pa·s.
