摘要
钻井液具有携带岩屑、平衡压力等重大作用,为调整其性能,需要对其中的离子进行连续探测。利用激光诱导击穿光谱(LIBS)技术对钻井液中的金属元素进行了初步研究,对钻井液中存在的Ca、Na、Mg、K元素进行了LIBS分析,获得了这4种元素的最佳探测条件。结果表明:Ca元素的采集延时为400 ns,采集门宽为1000 ns;Na元素的采集延时为500 ns,采集门宽为1500 ns;Mg元素的采集延时为500 ns,采集门宽为1500 ns;K元素的采集延时为500 ns,采集门宽为1000 ns。这说明采用LIBS技术探测钻井液中的金属元素是可行的。实验光路的搭建、实验参数的确定以及其他影响因素的讨论,都会为将来LIBS技术在钻井液分析中的应用提供有价值的参考。
Abstract
Drilling fluid has important functions of carrying debris and balancing pressure. In order to adjust its performance, we need to continuously detect the ions in the drilling fluid. The laser induced breakdown spectroscopy (LIBS) technology is adopted to detect metal elements in drilling fluid . From the LIBS analysis of Ca, Na, Mg and K elements in drilling fluid, the optimal detection condition is obtained. The results show that the delay is 400 ns for Ca element, 500 ns for Na, Mg, and K elements. The gate width is 1000 ns for Ca and K elements, and 1500 ns for Na and Mg elements. The application of LIBS on detection of metal elements in drilling fluid is feasible. The establishment of experimental setup, the determination of detection parameters, and other influence factors, can provide valuable reference for further research of LIBS on analysis of drilling fluid.
