Description
Technical field
The present invention relates to a kind of oilfield chemistry agent, in particular it relates to a kind of elasticity for fracture-pore reservoir
Adjust stream particle and preparation method thereof.
Background technology
Based on surface layer weathering crust, underground underground river solution cavity, disconnected control karst, oil reservoir has Carbonate Reservoir Reservoir Body
The feature that depth, anisotropism are strong, bottom water is strong, Tibetan oil mass natural depletion is fast is buried, causes two to adopt limitation, overall recovery ratio
It is low.It is that flush stage is short, water-free oil production period is short, energy declines that Carbonate Oil, which ensconces aggregate performance in natural energy recovery process,
Soon.Secondary oil recovery mainly supplements stratum energy by gas injection, water filling, and by well group gas injection, water filling come remaining between well of taping the latent power
Oil.Secondary oil recovery middle and later periods well group forms predominant pathway, and easily form has channeling or water after excessive round water filling, gas injection between well
It alters, gas injection or water filling can be caused to fail, even if still relatively low if having the whole recovery percent of reserves of abundant remaining oil between well.
There are two ways to exploiting remaining oil between such well at present：First, improving water injection pressure, start advantage water stream channel
Neighbouring secondary channel improves sweep efficiency；Second is that advantage water stream channel is blocked successively to nearly well band in water injection well distal end, by
Grade improves water injection pressure, starts secondary oil flow channel, to greatest extent Remaining Oil.Water injection pressure is improved, to pipeline requirements
