Description
Technical field
The present invention relates to the research field of gas reservoir, espespecially a kind of matrix imbibition measurement mechanism.
Background technology
Along with to the continuous exploration and development of unconventional gas resources, the research for Unconventional forage reservoir is also deepening continuously.At present, when studying unconventional reservoir, particularly low hole, hypotonic shale reservoir, one of the spontaneous imbibition intensity of reservoir rock research becoming emphasis.
The sandstone of shale spontaneous imbibition energy force rate routine is stronger, this wherein greatly reason just depend on the matrix of shale.When fracturing liquid carries out pressure break to shale reservoir, due to powerful capillary force, make liquid from crack to matrix flow, enter in the gap of matrix and inside thereof.This process displacement can go out the adsorbed gas of its content and by its deep research, can obtain some physical propertys of reservoir rock, as parameters such as the imbibition intensity of rock, imbibition speed and throat distribution.
From engineering viewpoint, carrying out in frac job to compact reservoir, fracturing fluid recovery (backflow) rate is one of numerous emphasis parameters paid close attention in frac job.At low permeability gas reservoir reservoir, particularly in clay shale with low permeability gas reservoir, because blowhole venturi is narrow, hollow billet effect is obvious, and rock has super dryness, its water saturation is also lower than irreducible water saturation, even if do not have high pressure during pressure break, fracturing liquid also can be entered in rock by spontaneous imbibition effect.
Usually in the fracturing liquid work carrying out conventional reservoir, because the agency part fracturing liquids such as pore constriction trapping are trapped in rock, reservoir is caused to the injuries such as water lock, but in clay shale with low permeability gas reservoir, fracturing liquid is trapped in after in rock, can be spontaneous to imbibition in matrix, thus reduce even solution and dewater the fracturing liquids such as lock to the injury of reservoir.
