摘要：红台低含油饱和度致密砂岩油藏直并常规压裂增产幅度小、稳产期短，难以形成商业开采价值。为实现该类油藏的增产、稳产以及解决见油周期长的问题，进行了体积压裂可行性评价和实施效果分析，利用形成复杂缝网的体积压裂技术解决增产、稳产难题。在确定影响该油藏体积压裂效果的主要图子(物性和压裂液量)和次要因子(砂量和平均砂比)基础上，优化压方式和工艺参数，解决见油周期长的问题，最终形成了分层系水平并开发、控制压裂液量600m/段、保持砂量规模60m 段，提高平均砂比至22%的体积压裂技术体系。现场试验结果表明，同比相同物性的直并，水平井体积压裂见油排液周期缩短 43.6%，目产油提高47.4%，有效期提高25%，为同类油气藏开发提供借鉴

Abstract: When conventional vertical well fracturing is applied in Hongtai tight sandstone oil reservoir of low saturation, its stimu-lation amplitude is low and stable production period is short, so it is difficult to realize the commercial production. In this paper, feasi-bility evaluation and implementation effect analysis of volumetric fracturing were adopted to realize stimulation, stable production and long oil production period of low oil saturation reservoirs. The difficulties of stimulation and stable production were solved by applying volumetric fracturing technology to create complex fracture networks. Fracturing mode and technological parameters were optimized to extend oil production period by identifying the primary factors (physical property and fracturing fluid volume) and secondary factors(proppant volume and average proppant concentration) that influence volumetric fracturing effect of Hongtai oil reservoir. In this way, the volumetric fracturing technology system for horizontal-well separate layer development was developed with fracturing fluid volumc 600 m'/section, proppant volume 60 m'/section and average proppant concentration 22%. It is successfully used in field. Compared with the vertical well with the same physical properties, horizontal-well volumetric fracturing is 43.6% shorter in liquid discharge period for
