Abstract:

For conventional silver nitrate titration to measure chlorine ion content has difficulties on human factors, drilling fluid additives in low accuracy, large error, and low accuracy of drilling strata containing aqueous recognition problem, the ionic liquid chromatography technology was introduced as a new application in identification of  drilling formation water property. The work area aquifers with different levels of ion chromatography identify patterns were established. The recognition of water content was consistent with logging results. It showed that using ion chromatography with water based evaluation model has better feasibility, reliability, and accuracy. The ion chromatography aqueous recognition model has good prospect of popularization and application.

Key words: Marine strata, Formation water, Aquosity recognition, Ion liquid chromatography

摘要： 针对常规硝酸银滴定法测量Cl- 质量浓度存在人为因素、钻井液添加剂影响导致精度低、误差较大,随钻地层含水性识别准确率低的难题,探索引进离子液相色谱技术在钻井地层含水性识别中的新应用,研究建立工区不同级别含水层的离子色谱识别模式。经上井应用评价,含水性识别与测井结果较吻合,表明利用离子色谱技术含水性评价模式的可行性及可靠性较好,准确性较高,展示了离子色谱含水识别模式良好的推广应用前景。
