摘要
针对碳酸盐岩储层储集空间类型,讨论了井壁成像测井和常规测井方法的响应特征及其适应性,在此基础上提出了自适应性定量评价方法和模型,包括孔隙度模型、渗透率模型以及饱和度模型。应用该方法对塔里木盆地奥陶系碳酸盐岩储层进行了综合评价,取得了良好的效果,证明该方法具良好的适应性。
Aimed at the various types of reservoir space in carbonate rock, the logging responses and adaptability,including full-borehole micro-resistivity scanner imaging logging and conventional logging are discussed. Based on this, self-adaptive quantitative method and models are proposed, such as porosity model, permeability model and saturation model. These method and models prove to be adaptive widely when they are applied in practical well data and the results are satisfying.
