Abstract

The effect of separately selected chemical agents Dissolvan 4411, Alkan 415, ND-12 and Gossipol resin, as well as their new compositions in the ratio Dissolvan 4411+ Alkan 415 + ND-12 + Gossipol resin = 1:1:1:1 (conventional name А-1) and ND-12 + Gossipol resin = 3:1 (conventional name А-2) on the physical-chemical characteristics of oil samples taken from Azerbaijani fields Muradkhanly, Bulla-deniz, Balakhany-Sabunchu-Ramana, Neft Dashlary and Surakhany has been studied. The process was carried out in two hours in the laboratory conditions at 20 °С temperature. Dissolvan 4411, Alkan 415 and ND-12 demulsifiers were taken in 600 g/t, Gossipol resin – in 200 g/t, and А-1 and А-2 compositions – in 800 g/t ratio correspondingly. It was defined that two hours after adding Dissolvan 4411, Alkan 415, ND-12, А-1 and А-2 compositions at 20 °С temperature into the oil samples from Muradkhanly, Bulla-deniz, Balakhany-Sabunchu-Ramana, Neft Dashlary and Surakhany fields, the parameters of density, viscosity, water content, chloride salts and mechanical impurities sharply decrease. The composition of resin, asphaltene and paraffin compounds increases. The freezing temperature in the oil samples from Muradkhanly and Bulla-deniz fields do not change while in the samples from Balakhany, Neft Dashlary and Surakhany fields it dramatically reduces. The results of comparative analysis carried out at 20 °С temperature in the laboratory tests revealed that specifically А-1 and А-2 compositions mostly affect the improvement of physical-chemical characteristics of oil samples from Muradkhanly, Bulla-deniz, Balakhany-Sabunchu-Ramana, Neft Dashlary and Surakhany fields. It justifies that the employment of multi-functional compositions in the preparation to transportation of heavy oils is more efficient.
单个和组成剂对油理化参数影响的研究
研究了分别选择的化学剂Dissolvan 4411、Alkan 415、ND-12和吉古波尔树脂及其新组合物,分别以Dissolvan 4411+ Alkan 415 + ND-12 +吉古波尔树脂= 1:1:1:1(常规名称А-1)和ND-12 +吉古波尔树脂= 3:1(常规名称А-2)的比例对阿塞拜疆Muradkhanly油田、Bulla-deniz油田、balakhany - sabunchul - ramana油田、Neft Dashlary油田和Surakhany油田的石油物化特征的影响。该过程在20°С温度下的实验室条件下进行,耗时两小时。溶解剂4411、Alkan 415和ND-12破乳剂分别以600 g/t、200 g/t、А-1和А-2组合物分别以800 g/t的比例加入。结果表明,在20°С温度下,将Dissolvan 4411、Alkan 415、ND-12、А-1和А-2组分加入到Muradkhanly、Bulla-deniz、Balakhany-Sabunchu-Ramana、Neft Dashlary和Surakhany油田的油样中2小时后,其密度、粘度、含水量、氯盐和机械杂质等参数急剧降低。树脂、沥青质和石蜡化合物的组成增加。Muradkhanly和Bulla-deniz油田的石油样品的冻结温度没有变化,而Balakhany, Neft Dashlary和Surakhany油田的样品则急剧降低。在20°С温度下进行的实验室对比分析结果表明,А-1和А-2组分对Muradkhanly、Bulla-deniz、balakhany - sabunchul - ramana、Neft Dashlary和Surakhany油田油样物理化学特性的改善影响最大。说明多功能组合物在稠油制备和输送中的应用效率更高。
