摘　　要：地层流体分析是贯穿于油气勘探开发全过程的一项基础性工作,先期的地层流体分析和认识对于试油选层、工程设计有很大的影响。地层含水分析在地层流体分析和识别中具有突出的地位,但目前却缺乏相应的技术手段和方法,针对这种现状研究开发了岩心离子探测技术,建立了基于离子探测技术的地层含水分析方法,首次推导出利用岩心离子探测数据计算地层含水饱和度的公式,并以实际资料验证了该方法的可行性,实际应用情况表明其效果良好。Formation fluid analysis is a basic work which runs through the entire oil and gas exploration and development process, the early formation fluid analysis and recognition has much influence on the oil testing bed choosing and the engineering design. Analysis on water-bearing formation occupies the projecting position in formation fluid analysis and recognition, but at present, the corresponding technology means and methods are lacked. The core ion detection technology was developed according to such situation. The paper states the analysis method for water-bearing formation, which is based on ion detection technology, induces the formula by using core ion detection data to calculate formation water bearing saturation for the first time and verifies the feasibility of the method by practical data. It shows good effect by practical application.
