陕甘宁盆地上古生界砂岩储层物性较差，非均质性强，粘土矿物种类多、含量高，是进行压裂效果分析首先要考虑的问题．通过对储层地质特征的详细研究，在工艺方面提出了适合本地区的具体措施．压裂液的性能、支撑剂的选择、施工参数以及压裂液的反排，必须与储层的地质特征结合起来考虑．才能达到保护气层和改造气层的目的． The Upper Paleozoic sandstone reservoirs in the Shanxi-Gansu-Ningxia basin have poor physical properties, strong heterogeneity, many clay minerals and high contents, which are the first issues to be considered in fracturing effect analysis. Through the detailed study of the geological characteristics of the reservoir, concrete measures for the region are proposed in terms of technology. The performance of the fracturing fluid, the choice of proppant, the construction parameters, and the anti-displacement of the fracturing fluid must be considered in conjunction with the geological features of the reservoir. In order to achieve the purpose of protecting and reforming the gas layer.
