【摘要】 针对特低渗透储层的岩心分析困难、测井解释难度大、储层物性井间外推不准等问题 ,提出了一套行之有效的系统的解决方法。具体做法是 :首先 ,利用核磁共振成像技术来获得岩心的孔隙度、渗透率、含油饱和度资料 ;然后 ,利用改进了的人工神经网络建立高精度的孔隙度、渗透率和饱和度的测井解释模型 ;最后 ,利用分形克里格技术对储层参数进行井间及外推插值。将这套方法用于某油田S68区块扶余油层的储层参数预测 ,处理效果较为理想。更多还原

【Abstract】 It is difficult to do conventional core analysis,to do well logging interpretation and to do parameter prediction inter wells.So a way to solve these problems is provided.The method is as follows:porosity,permeability and oil saturation are measured by NMR. The interpretation model of porosity,permeabiligy and saturation are set up by using of improved NN.Natural prarameters inter wells of reservoir are predicted by fractal kriging technique.This method is used in one oil field S68 reservoir.It is proved the method is very effective.更多还原
