针对高含盐原油 ,在实验室进行了脱除原油中非水溶性有机钙盐的试验及机理研究。对EDTA(乙二胺四乙酸 )等数种有机脱钙剂进行不同原油的脱钙性能试验。采用筛选出的几种脱钙剂在剂 /钙摩尔比为 1～ 3时 ,脱钙率达 80 %以上 ,大部分脱后原油含钙量可降到 5 μg/g以下
Aiming at the high-salt crude oil, the experiment and mechanism research on the removal of non-water-soluble organic calcium salts in crude oil were carried out in the laboratory. On EDTA (ethylenediaminetetraacetic acid) and several kinds of organic decalcification of different crude oil decalcification performance test. The decalcification rate of more than 80% of the selected decalcification agent is 1 ~ 3, the calcium content of most of the decarburized crude oil can be reduced below 5 μg / g
