以鄂尔多斯盆地延长组油层地质特征、储层分类研究为基础 ,通过大量现场应用 ,总结出适合各类延长组油层的射孔技术、钻具结构、支撑剂、压裂液及配套的压裂施工参数 ,并详细介绍了几种能不同程度提高单井产能、防止大量吐砂、有效抑制底水的压裂技术及其应用效果。这一整套改造技术对压裂试油及提高单井产量具有重要的指导意义
Based on the study of the geologic characteristics and reservoir classification of the Yanchang Formation in the Ordos Basin, a series of perforation techniques, drilling structures, proppant, fracturing fluid and associated fracturing construction suitable for various Yanchang Formation oil reservoirs are summarized through a large number of field applications Parameters, and introduced several kinds of fracturing technology that can improve single-well productivity to a large extent, prevent a large amount of sand from being ejected and effectively restrain bottom water, and its application effect. This set of retrofitting technologies has important guiding significance for fracturing test oil and improving single-well production
