离子色谱在地层流体参数分析的应用

Application of Ion Chromatograph in the Analysis of the Formation Fluid Parameters

电缆地层流体取样是比较成熟的技术,广泛应用在石油勘探阶段。本文方法利用离子色谱,通过对所取样品进行离子分析,可以判别样品中泥浆混入情况,反算地层水总矿化度,进而推算出地层水电阻率。这些流体物理及化学参数在油气勘探和开发阶段具有重要的意义,能够有效划分油田的油气层,指导勘探开发作业。

The wire line formation fluid sampling was a comparatively mature technology which was widely utilized in petroleum exploration phase.The ion concentration of samples can be analyzed via chromatography , thus the extent of mud mixed with sample can be determined.The total salinity and resistivity of formation water were calculated accordingly as well.The physical and chemical parameters of fluid were used to identify oilfield reservoir , which was of great significance in the oil and gas exploration and development.
