SG-DSZY compound plugging and oil saving technology

   Technology Introduction:  

SG-DSZY composite plugging technology includes two systems: the main system is a low damage, deep penetration of the multi-organic acid solution solution; deputy system is composed of amphoteric surfactants and small cationic antihypertensive agent-based compound system. When the construction of the system of multiple organic acids and amphoteric active agent can effectively clay, scale, glial, asphaltene and other plugs to clean up. Post-slug into the antihypertensive injection system, to achieve long-term antihypertensive effect.

     Features:      

1, Multiple organic acid plugging system has excellent slowness.

2, The treatment layer rock skeleton damage small.

3, The construction of the column and the equipment is less corrosive.

4, Acid formation speed is slow, have a longer penetration distance.

5, And the use of antihypertensive injection system greatly extended the validity of measures.
