摘要
通过开展中、高渗透性油层模拟注水驱油实验,以稳态法测定油-水相对渗透率,制备饱含油至残余油的不同含水率岩样,对岩样进行岩石热解、饱和烃气相色谱及荧光显微图像分析,研究岩石热解、饱和烃气相色谱参数及荧光显微图像特征随含水率上升的变化规律及趋势,总结中、高渗透性油层水淹变化录井资料响应特征,探讨其水淹机理并对实验数据中产生的特殊现象进行分析。实验证明录井各单项资料能够反映中、高渗透性油层不同水洗状况下的特征,为今后录井资料评价中、高渗透性油层水淹程度奠定了理论基础。
By the simulation experiment for water injection flooding in the medium and high permeable reservoirs,the oil-water relative permeability was determined with the steady state method.By preparing the rock samples of different moisture contents from oil-saturated to the residual oil,the authors carried out the analysis for rock sample pyrolysis,gas chromatography of saturated hydrocarbons and fluorescence microscopy image and studied the varying rules and trends that parameters of rock pyrolysis,gas chromatography of saturated hydrocarbons and the features of fluorescence microscopy image change with the rising of the moisture contents.The authors summarized the flooded variation and the response characteristics of mud logging data in the medium and high permeability reservoir,discussed its water flooding mechanism and analyzed the particular phenomena which happened in the experimental data.The experiment proved that each single mud logging data can reflect the characteristics of the different water flooding conditions in the medium and high permeability reservoirs,providing the theoretical foundation in evaluating different water flooding extent of medium and high permeability reservoirs in future.
