石油及天然气岩层酸化所用的酸,是浓度为30～37%的工业盐酸.油矿储酸多用酸池.过去采用液体石蜡密封,效果不好,大量氯化氢气体溢出,污染环境.为解决此问题,南充炼油厂研制出一种良好的盐酸液封油,经工业试生产和在川南、川西南等矿区三年多的使用,结果表明:封闭酸液效果良好(经测定,空气中氯化氢含量为0.626～1.892克/米~3,大大低于规定15克/米~3指标);挥发损失少,为原用液体石蜡的1/18;化学稳定性好,不
The acid used in the oil and gas rock formation acidification is industrial hydrochloric acid with a concentration of 30-37% .Oil acid storage and acid pool used in the past.Used liquid paraffin sealing, the effect is not good, a large number of hydrogen chloride gas overflow, pollute the environment.To solve this problem, Nanchong Refinery developed a good liquid hydrochloric acid seal oil, after industrial trial production and in South Sichuan, Sichuan and other mining areas more than three years of use, the results show: closed acid good effect (measured in the air hydrogen chloride content of 0.626 ~ 1.892 g / m ~ 3, much lower than the specified 15 g / m ~ 3); less volatile loss, 1/18 of the original liquid paraffin; good chemical stability, no
