中低渗油藏在我国已探明储量中占比越来越大,目前针对储层的沉积、成岩等方面的研究主要是从宏观角度入手,对储层自身的微观结构及其孔隙分布认识不足,使得而传统开采方法应用到该类油藏时效果并不明显。因此,对中低渗油藏储层微观孔隙的深入研究是高效开发该类油藏的关键基础技术,利用所得特征参数对测井数据进行解释、工作液的设计具有重要的指导作用。
The low and middle permeability reservoirs account for an increasing proportion of proven reserves in China. At present, researches on reservoir sedimentation and diagenesis mainly focus on macroscopic observation of the reservoir’s own microstructure and its pore distribution Insufficient, so that the traditional mining methods applied to this type of reservoir effect is not obvious. Therefore, the in-depth study on the micro-pores in the reservoir of medium-low permeability reservoirs is the key basic technology for the efficient development of such reservoirs. The use of the obtained characteristic parameters to interpret the well logging data and the design of the working fluid has an important guiding role.
