Note 1.The above testing condition: Jiahua-grade G oil well cement slurry, Salt water proportioning (salt concentration of 15% to 20%), water-cement ratio 0.45-0.48, ZOE-012 amount of 5% to 8%, slurry density 1.90 g / cm3
2. The initial viscosity refers to the maximum index during the period of the first 15mins to 30mins of the thickening test while the cement slurry is stirred.
The appearance of Salt and temperature tolerance and fluid loss Agent is light yellow viscous liquid.
It is a kind of cement admixtures that applies to salt layer cementing operation.
It can effectively control the loss of water to avoid the enlargement of the well hole caused by salt dissolution.
It effectively prevent the formation of micro-annulus and annular gas migration, and improve the quality of the cement bond.
Cementing Mud Fluid Loss Agent ZOC-003 is adaptable to various cement, has good compatibility with common oil well cement Admixtures. Slurry has good liquidity, no thickening phenomenon, the more free water puree greatly reduced; It has wide temperature scope (50-180 ℃), and the thickening time can be adjusted according to construction conditions. General dosage is 5% to 8%.
