摘要
苏北盆地阜二段页岩地应力高、两向应力差大、平面上断层裂缝带发育、纵向上非均质性强,压裂改造难度大.以提升复杂度、扩大改造体积、提升EUR为 目标,在H2侧HF井采用了水平井密切割体积压裂技术.为直观评价储层改造效果,该井采用了微地震监测技术.通过微地震实时监测,指导压裂参数调整和工艺优化.同时,通过微地震监测结果,了解裂缝延伸情况、裂缝复杂度和改造体积.
Abstract
The shale oil in the Funing Formation of Subei Basin has high in-situ stress,large two-way stress difference,developed fault fracture zone on the plane,and strong heterogeneity in the longitudinal direction,which makes fracturing transformation difficult.With the goal of increasing the complexity,ex-panding the volume of the renovation and increasing the EUR,the horizontal well-dense cutting volume fracturing technology was adopted in the H2HF well.In order to intuitively evaluate the effect of reservoir transformation,the well adopts microseismic monitoring technology.Through the real-time monitoring of microseismic,it can guide the adjustment of fracturing parameters and process optimization.At the same time,through the results of microseismic monitoring,the fracture elongation,fracture complexity and transformation volume can be understood.
