AU-8 Anti-Swelling/SControl Agent

Sproduction will reduce oil production, damage to the casing cause other damage to the equipment, chemical mechanical methods to control the formation of unconsolidated sand, has been widely used in various fields, a complete matching technology. But the mechanical processes such as sclay, fine son the higher levels of sstrata, showing the obvious limitations of low efficiency, short period, while the anti-construction process frequently flushing, red sand, it is difficult to successfully fscontrol operations. Thus, the stability of fine sand, sto prevent the expansion of operations in a temporary stabilization of sand, the production has an important significance. According to the site needs, we developed a powder that may prevent the migration of scan prevent the expansion of the clay additives, the indotests show that a good layer of loose s"curing" effect, as well as some anti-erosion ability. The agent in connection with straight carbon chain a multi-amine carbon chain cationic group, the performance of the wettability of sandstone, can be adsorbed on the surface. Connected to the sand, to sconsolidation purposes, the cationic group has a strong affinity fclay performance, the ability of hydrocarbon salt erosion, which is due to the positivelyged ions on the polymer chains clay layers the surface of the crystal with low cation ion exchange occurs, "neutralize" the clay crystal layer the surface of the negativege, the crystal layer the particles reduce the electrostatic repulsion, crystal layers are not easily dispersed. Meanwhile, the branched-chain can be adsorbed simultaneously to multiple layers crystal particles, thereby inhibiting the dispersion of clay particles migration, play a role in stabilizing clay particles.
