GD-1 Anti-High Temperature Drag Reducing Agent for Oil Well Cementing
description1
Product Description
GD-1 drag reducing agent (dispersant) can obtain a suitable slurry rheology by adjusting the surface charge of the cement particle, thus to reducing pump pressure, and improving the displacement efficiency, and fulfilling the purpose of ease of construction.
Characteristics
GD-1 is Polymerized and modified by raw formaldehyde, acetone and other materials.
Dosage of GD-1 is 0.05%~0.50%(BWOC),if there is special application, it cannot be limited by this range.
GD-1 is easy to be dissolved in water.
It can effectively regulate slurry rheology along with the increase of dosage amount, and can reduce slurry’s consistency.
It has a good capability of anti-high temperature, applicable to 30℃~180℃(BHCT).
It can make the cement stone denser and develop the anti-pressure capability and also has a certain ability of controlling fluid loss.
It has a certain ability of retarding.
GD-1 can both dry mixing and wet mixing.
It has a good compatibility with other additives.
