Clay Stabilizer

Details:

<p> <strong>AU-4 </strong><strong>Clay Stabilizer</strong><strong> </strong></p> <p align="left">  </p> <p align="left"> Oil field injection, operation, drilling, fracturing acidizing other construction process, will inevitably produce clay swelling migration, reducing the formation permeability, increased water injection production difficulties, access to our extensive domestic international data, based on research development a new anti-swelling agent. It has low uniform molecular weight, to prevent bridging clogging pores in the sandstone surface of the performance of non-wetting, reduces the water saturation on the clay surface has a strong affinity, the ability of hydrocarbon salt erosion, due to polymer chain of positivelyged ions of chlorine the fourth crystal layer between the clay the surface of the low cation cation exchange, "in" the clay crystal layers surface negativege, so that crystal layer reduce the electrostatic repulsion between the particles . Crystal layers instead of dispersing the Yi River; while the polymer chains can adsorb to more than one crystal layer particles, thereby inhibiting the dispersion of clay particles migration, play a role in stabilizing clay particles. The product is mainly suitable flow-permeability reservoir anti-swelling treatment.</p> <p align="left"> <br /> Specification:<br /> (1) Appearance: dark brown transparent liquid;<br /> (2) Density: 1.04 ~ 1.07g/cm3;<br /> (3) Viscosity: 100 ~ 150mPa.S;<br /> (4) Freezing point: ≤ -20 °C;<br /> (5) anti-swelling capacity (VH): ≥ 75%;<br /> (6) anti-erosion ability: ≥ 90% (0.8cm / s);<br /> (7) Temperature: ≤ 150 °C;<br /> (8) water-soluble: Good;<br /> (9) compatibility: Good.</p> <p align="left"> <br /> Usage:<br /> In the working solution by adding 2 ~ 4% EL-4 mix well.</p> <p align="left"> <br /> Packaging:<br /> 25kg, 50kg plastic drum 200kg metal pail.
