摘要
在地层评价中,束缚水饱和度是体积法计算储量,油气水层评价的重要参数之一。束缚水饱和度参数与天然气产出密切相关。本文采用两种方法岩电实验法与压汞实验法对克深低孔低渗地区岩样进行了束缚水饱和度实验研究。通过资料分析,得出克深低孔低渗地区束缚水饱和度计算模型,并进行了公式验证和误差分析。束缚水饱和度模型计算的束缚水饱和度与岩心束缚水饱和度有较好的符合率。并将束缚水饱和度模型用于疑难井评价,得到较好的应用效果。
In formation evaluation,bound water saturation is one of the important parameters in calculating reserves and evaluation of oil and gas layer.It has a close relationship with gas output.In the paper,based on the mercury injection experiment and the litho-electric experiment,the bound water saturation is studied with the rock samples in Tarim low permeability reservoirs.The bound water calculation model of this area is obtained by data analysis.It is verified by the formulae and the error analysis.The calculated bound water saturation has good coincidence rate with the one of core sample analysis.The bound water saturation model has been used in evaluation of some difficult wells and gained good results.
