低渗透储层流体测井识别方法研究与应用——以塔河油田石炭系为例

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。

Research and Application of Low Permeability Reservoir Identification Method Taking Tahe Oilfield as an Example

The cause of low permeability reservoir leads to kinds of solutions to the logging interpretation results and there exist extremely difficulties in logging identification and eval- uation. So it is significant to systematically analyze the genetic mechanism of low permea- bility reservoir, the mechanism of logging response and other problems and evaluation methos in logging evaluation. Through the logging interpretation of oil and gas reservoir in Carboniferous Kalashavi Formation in Tahe Oilfield and on the basis of the experimental data analysis, the core analysis data and the reliable logging information from the aimed layers are used to establish the logging interpretation models of the physical properties （po- rosity, permeability）, saturation parameters and many techniques of oil gas and water layer interpretation. It has improved the ability of identifying oil gas and water layers and has a-chieved an e{{ective result.
