Research on the adaptability of natural gas drive for low-permeability reservoir

The productivity equations in steady fluid flow and oil-gas two-phase flow with solution gas drive of horizontal wells in low-permeability reservoirs were established by equivalent flowing resistance method.

The low-permeability reservoir is remarkably characterized by threshold pressure gradient,which makes high filtration resistance,declines sweep scope of injected water,owing to the threshold pressure gradient in the process of the fluid flow through porous media,how to confirm the injected water effective scope is one of the key techniques to develop the low-permeability reservoir effectively.
