Application of microseismic monitoring technology in fracturing of H2HF shale oil well
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.
