由于低渗透储层的成因复杂,导致测井响应解释结果具有多解性,测井识别和评价存在极大的难度。因此,系统地分析低渗透储层的成因机制、测井响应机理,以及测井评价中存在的各类问题及评价方法具有重要的意义。通过对塔河油田A区石炭系卡拉沙依组油层测井解释研究,在实验资料分析的基础上,利用岩心分析数据和目的层段可靠的测井信息,建立物性(孔隙度、渗透率)、饱和度参数测井解释模型,和多种进行油气水层解释的技术,突出流体性质的差异,提高对油气水层的识别能力。在实际应用解释中取得了较好的效果。
Due to the complicated genesis of low permeability reservoirs, which leads to the multi-solution of logging response interpretation results, there is great difficulty in logging identification and evaluation. Therefore, it is of great significance to systematically analyze the genetic mechanism of low permeability reservoirs, the well logging response mechanism, and the various problems and evaluation methods in well logging evaluation. Based on the analysis of the logging data of the Carboniferous Karashayi Formation in the A area of Tahe Oilfield, based on the analysis of the experimental data and using the core analysis data and reliable logging information in the target interval, the physical properties (porosity and permeability) , Saturation parameter logging interpretation model, and a variety of techniques for interpretation of the oil-gas aquifer, highlighting the differences in fluid properties and enhancing the ability to recognize hydrocarbons. In the practical application of the results achieved good results.
