Productivity-Prediction Model of Acid Fracturing Horizontal Well in Fracture-Cavity Reservoir

Abstract:

Due to the particularity of the fracture-cavity reservoir space, the seepage theory developed from homogeneous reservoir cant be applied to predict the productivity of fracture-cavity reservoir. This paper simplified the fracture-cavity system to an oil storage vessel, and based on the basic principles of material balance, established the productivity-prediction model which was suitable for the acid fracturing horizontal well in fracture-cavity reservoir. The results showed that the productivity of fracture-cavity system was high and steady. Meanwhile, the connected fracture-cavity system had a greater contribution to increasing production capacity than other factors.
