Study on the Fracturing Parameters and Productivity of Horizontal Wells.

The article presents a study which investigates the hydraulic fracturing operation in the tight oil reservoir hybrid grid block (HGB) in the Songliao Basin, China to find out the reason for the low productivity after the fracturing operation. A comparison of oil saturation distribution and pressure distribution of different fracture length is offered. The investigation of completed simulations of hydraulic fracture pumping stage and flow-back stage is also revealed.
