【摘要】：使用传统的评价方法对鄂尔多斯盆地CHN油田这类受构造和岩性控制、粒度较细、基质复杂的储层进行流体识别会存在较大误差。通过对阿尔奇公式的改进,应用电阻率-M(油水分界线)、电阻率-N(油水分界线)、以及电阻率比值-声波时差、电阻率比值-自然电位交会等4种综合测井方法进行流体识别,其中电阻率比值法可以将储层的含油性评价从定性提高到定量判断水平,从而完善了该类储层的测井综合流体评价方法。同时也讨论了储层含油性与构造、岩性的关系。研究实例表明以上方法可较为准确地识别这类复杂储层的流体性质。
[Abstract]:The traditional evaluation method is used to identify the fluid in the CHN oilfield of Ordos Basin, which is controlled by structure and lithology, with fine granularity and complex matrix. The improvement of Archie formula is carried out. Four comprehensive logging methods such as resistivity -M( oil-water demarcation line), resistivity (-N), resistivity ratio-acoustic time difference and resistivity ratio-natural potential intersection are used to identify fluid. The resistivity ratio method can improve the oil-bearing evaluation of reservoir from qualitative to quantitative, thus improve the comprehensive fluid evaluation method of this kind of reservoir, and also discuss the oil-bearing property and structure of reservoir. Examples show that the above methods can accurately identify the fluid properties of this kind of complex reservoirs.
