Characteristics of crude oil wax by simulating CO2 flooding process of Yanchang Oilfield
摘要
Abstract
The wax deposition tendency and its characteristics in crude oil produce at a CO 2 flooding oilfield block were investigated under various CO 2 partial pressures .The wax deposition rate ,wax deposition percentage and wax content were calculated .The characteristics of wax pre-cipitation point curves were also analyzed .The results indicated that both wax deposition rate and wax deposition percentage of crude oil increased with CO 2 partial pressure increasing ,while wax content decrease meant wax deposition more significantly .In addition ,wax precipitation point of crude oil by CO2-processed moved in the lower temperature direction ,and the wax content was lower than that of unprocessed crude oil .关键词
