摘要
应用微地震波裂缝监测技术 ,研究了克拉玛依八区下乌尔禾组油藏裂缝分布特征及油藏油水宏观流动特征 ,总结了该油藏裂缝的分布规律 ,指出了裂缝发育的方位和平面展布形态 ,分析了裂缝研究成果在调整井设计、注采井网调整、压裂参数选取以及平面注水管理等方面的应用效果。结果表明 ,处理好注采井与裂缝、地应力的关系是低渗透裂缝性油气藏高效开发的关键
Distribution characteristics of the fracture and the macroscopic oilwater flow features of oil reservoir in lower Wuerhe oil reservoir in Kelamayi region 8 are researched by the microseismic wave fracture monitoring technology. The rule of the fracture distribution in the oil reservoir is summarized. The orientation and plane extension of fracture growth are pointed out. The application effect of the fracture research results on the adjustment well design, the injectionproduction well pattern adjustment, fracturing parameters selection and the plane water flooding management are analyzed. The results show that good relationship among injectionproduction wells, fracture and earth stress is the key of high efficiency development in lowpermeability fractured hydrocarbon reservoir.
