Laboratory Research on Reservoir Adaption of Water Fracturing
Water fracturing is vast applied in low permeability oil-gas filed, and gains extremely economic benefit. But not all low permeability reservoirs are suitable for water fracturing. This paper analyzed the fracture deformation characteristics and closed form in complex stress state, the fracture surface roughness and shear-slip caused the fracture surface couldn’t be completely meshed, there was residual space. Based on the characteristics, the self-support fracture combination and conductivity test method were established. The non-dimensional conductivity as the evaluation index, the water fracturing reservoir screening method was established.
