鄂尔多斯盆地XX地区长6_2储层综合评价方法研究

Study of the Comprehensive Evaluation Methods for Chang 6_2 reservoir in XX Area of Ordos Basin

针对鄂尔多斯盆地XX地区长6_2储层流体识别难点,开展了储层特征、储层孔渗饱参数模型研究,采用自然伽马与电阻率乘积法建立交会图版,综合交会图版法、横向对比法、快速色谱综合分析法、岩心观察法和核磁共振法进行流体识别,建立了一套适用于该区该地层储层参数精细解释、流体识别的综合评价方法,使得研究区该储层的解释符合率明显提高,为该区的油田开发、测井解释及工程施工提供了很好的技术支撑。

Study is carried out to the reservoir characteristics and the reservoir modeling(porosity, permeability and saturation) of the Chang 62 layer in XX area of Ordos Basin. The GR and resistivity data are used to create the cross-plot. Synthesized cross-plots, crosswise comparison, fast chromatography analysis, core observation and nuclear magnetic resonance method are used to identify the reservoir fluid, setting up a comprehensive evaluation method about the Chang 62 reservoir parameters interpretation and fluid identification. This method was successfully used in XX area. The logging interpretation and the coincidence rate are improved. It provides greatly support the development of XX area.
