Application performance

1. Applicable in fresh water slurry, seawater slurry, and slurry containing 2% CaCl₂.

2. Fast early strength development.

3. Enhance suspension stability and prevent against sedimentation.

4. Short setting transition time.

1. Designed for lightweight cement slurry system and normal density cement slurry with strong dispersity.

2. Thicken cement slurry to enhance suspension stability, prevent against sedimentation, little free fluid.

3. Fast early strength development.

1. Designed for moderate-low temperature oil well with low cost.

2. Suitable for low, normal and high density slurry.

1. Especially suitable for moderate-high temperature oil well.

2. Control fluid loss in low, normal and high density slurry.

1. Designed for normal density cement slurry.

2. The thickening time decreases with increasing temperature and compressive strength increases with increasing temperature.

1. Especially suitable for fresh water cement slurry at low temperature.

2. Short thickening transition time and setting transition time.

3. Promote the early strength development of low-temperature set cement.

Preparation method for different types products

Dry-mixed type (D type) fluid loss additive can be made when mix high purity powder (P type) with materials such as slag, silica flour, flyash etc .

Dual-purpose type (T type) fluid loss additive can be made when mix high purity powder (P type) with salt.

Liquid product (L type) is made when high purity power is dissolved in water with a certain concentration. If it is not put into use immediately after production, preservative and germicide should be added to prolong its shelf life.
