| 摘 要： | 经典Archie公式解决了测井数据的定量计算问题,但是,Archie公式只能用于孔隙结构相对简单的储层.面对日益复杂的油气勘探对象,Archie公式的计算精度受到一定的限制.本次研究,应用球管模型方法,针对不同孔隙结构研究了岩石饱和盐水及饱和油气时的导电性质,得到了不同孔隙结构、具有不同流体饱和度时岩石导电性的数值模拟结果. 本次研究的数值模拟结果证明岩石孔隙结构是导致岩电实验数据发散现象的因素之一,对比孔隙结构不同而饱和度相同岩石的导电性质,证明复杂孔隙结构是形成低电阻油层的重要因素.

| Abstract: | The classic Archie's Laws give solutions in quantitative logging analysis. Unfortunately, only in the reservoir with simple pore structure the Archie's Laws are suitable. For many complex reservoirs appearing in oil exploration, the classic Archie's Laws fail to provide right oil saturation in logging analysis. Based on the Sphere-Cylinder Model, in this paper we study rock resistivity and obtain the numerical simulation result for different pore structures and oil saturations. By means of the numerical simulation and analysis, we conclude that pore structure is the principal factor to cause experimental data scatter. After comparing the rock resistivity of different pore structures but the same oil saturation, we confirm that the complex pore structure leads to the low resistivity in oil-bearing zone. |
