Fracturing Technologies for Horizontal Wells in the Second-Class Shale Oil Reservoirs of the Lower Sweet Spot Areas in Jimusar

  • 摘要: 为了解决准噶尔盆地吉木萨尔页岩油因其流度低和储层层理发育缝高受限导致水平井提产困难的问题,提高下甜点二类储层的有效动用程度,开展了密切割改造提升缝控程度、薄互层穿层压裂增加纵向动用程度技术攻关。研究了密切割改造技术,将平均簇间距缩短至13.6 m,大幅提高了页岩储层缝控程度;提高了直井压裂施工的排量及冻胶用量,验证了下甜点二类储层具备穿层压裂的可行性,形成了以水平井12~14 m3/min大排量、冻胶和滑溜水多段塞泵注、中小粒径支撑剂组合和2.7 m3/m高加砂强度等为核心的穿层压裂关键技术,保证了层理转折裂缝有效支撑。现场试验表明,该技术能够提高水平井压裂动用体积,二类储层试验水平井压裂后第1年累计产油量达9 183 t,是前期水平井产油量的3倍以上。研究结果表明,水平井密切割穿层压裂技术可以解决二类储层多薄油层难动用的问题,为页岩油二类区有效动用提供了新的技术途径。
