Factors affecting productivity of fractured horizontal wells

Fracturing, an important measurement used to develop low permeability reservoirs, has been used widely in hydrocarbon exploitation. Based on previous studies, this paper, applying mathematics and fluid mechanics, draws a productivity prediction model for fractured horizontal wells. According to the technical means of numerical simulation, the productivity of fractured horizontal well in an actual low permeability oil reservoir has been tested by using this model. The impact of fracture length, number of fracture and space distance on productivity are analyzed, which will provide guidance for optimization of fractured horizontal wells. © 2013 Springer-Verlag GmbH.
