液质联用技术在石油磺酸盐质量控制中的应用

Application of LC-MS technology in quality control of petroleum sulfonate

主要针对胜利油田石油磺酸盐(SLPS)样品,建立了液质扫描方法,并以孤岛B61二元区块为例,分析了SLPS不同时间产品质量变化。通过相似度比较可以看出,石油磺酸盐的质量水平有所提高,但总体水品不是很高(未高于0.6),仍需要不断提高石油磺酸盐的质量水平。不同厂家的石油磺酸盐的存在差异,需要对不同厂家的石油磺酸盐样品进行对比选择。

Considering the complicated components of petroleum sulfonate in Shengli oilfield （ SLPS ）,a liquid chromatography-mass spectrometry（LC-MS） method was established to an- alyze the SLPS used in B61 unit of Gudao oilfield. Similarity degree was defined and used to determine the composition change of SLPS products at different times. According to the re- sults of similarity degree, the product quality of SLPS has become better in recent years, however, the overall quality is not high （〈0.6）.The quality of SLPS needs further improve- ment to meet the requirement of field application, the product quality from various manufac- turers differs significantly.Therefore,it is necessary to make a thorough comparison between different manufacturers during formulation design of surfactant-polymer flooding.
