Abstract

The network fracturing has become the key technology to develop the tight oil reservoirs. This fracturing technology creates a complex fracture network in the stimulated region. The primary goal of this paper is to optimize the fracture system conductivity in tight oil reservoirs, and to analyse the sensitivity of fracture system conductivity ratio on matrix permeability. To accurately capture the flow characteristic in the fracture system, a DK-LS-LGR numerical model was adopted. Then the influence of primary fracture conductivity and fracture network conductivity on oil recovery was analysed respectively, and a dimensionless conductivity ratio of primary fracture and fracture network was introduced to make the research results universal. This work also considered the influence of matrix permeability on conductivity ratio and obtained a uniform trend with the previous given condition.
