Study on Unproppant Waterfrac Flow Conductivity Mechanism and Test Method

Li WANG, Tie YAN, Hongliang WANG


The main reason for the success of unproppant water-fracs is that uneven crack surface can form a self-supporting which achieves the objectives of diversion. It needs two conditions, one is the surface roughness of the crack surface, the other is the shear-slip between fracture surfaces. In this paper, the influential factors and influence law of slippage and the mechanism of forming residual space when the crack closed are exposed with the finite element method. The preparation method of water-fracs self-supporting fracture surface combination and test method of flow conductivity are established. It supply the means by knowing water-fracs increasing production mechanism and suitable reservoir conditions.
