Description

(54) СПОСОБ ПРЕДОТВРАЩЕНИЯ ОБРАЗОВАНИЯ ОТЛОЖЕНИЙ ПАРАФИНА В НЕФТЕПРОМЫСЛОВОМ 12 (54) A method for preventing the formation of deposits in oilfield PARAFFIN 12

ОБОРУЛЮВАНИИ OBORULYUVANII

зависит от физ«ко-химических свойств нефти. It depends on the physical "co-chemical properties of the oil. Кроме того, он обладает депрессорными свойстбами , что Очень важно при перекачке нефти по нефтепроводам, особенно в зимнее врем . Furthermore, it has svoystbami depressor, which is very important when pumping oil through the pipeline, especially in winter time.

  1. Формула изобретени The claims
    Способ предотвращени образовани отложений парафина в нефтепромысловом оборудовании при добыче и транспортировке нефти с использованием полимерной присадки, отличающийс тем, что, с целью повышени эффективности способа предотвращени образовани отложений парафина путем обеспечени возможности введени в нефть полимера без предварительного растворени в углеводородном растворителе , в качестве полимерной присадки используют тройной сополимер этилена с винилацетатом и N-винилпирролидоном. A method for preventing the formation of paraffin deposits in oilfield equipment during production and transport of oil by using a polymeric additive, characterized in that, in order to increase efficiency of the process to prevent the formation of paraffin deposits by allowing administration in oil polymer without prior dissolution in a hydrocarbon solvent such as polymeric additives use terpolymer of ethylene with vinyl acetate and N-vinylpyrrolidone.
