离子色谱技术在钻井现场的应用研究

将离子色谱技术(IC)应用于钻井现场的钻井液滤液分析,从而获取所钻井钻遇地层的可溶性矿物的性质、地层水的类型等资料信息。离子色谱技术在这一领域的应用尚属探索阶段,但通过现场两口井的试用已见到较好的应用效果,文章简介了该技术的应用前景及价值,如:确定油水界面的位置及指导钻井液的调配、确保井下安全等。这方面的论述,对分析化验仪器向井场转移实现多手段综合分析具有一定的促进作用。

Wellsite application of ionic chromatographic technique

Using ionic chromatographic technique (IC) to analyse drilling fluid on wellsite can obtain information of soluble mineral property and formation water type. It is only at exploring stage for the application in this field. But it has got better practical effects with two wells , tests. The paper introduced the prospect and value of the technique, such as determining oil-water contact position, guiding the condition of drilling fluid and ensuring downhole safety etc. It can promote the shift of analysing instrument to wellsite to realize comprehensive analysis.
