Universal Fluid Loss Additive

Description

SYJ_4 is one kind of high molecule weight polymer mixed with some assistant materials. In cement slurry ,it can be adsorbed onto the partical surface effectively, change physical chemistry performance. forming a cross_linked net among polymer molecules. Then it can form a compact film when the certain pressure differential occurred between the slurry and the formation. The slurry applied SYJ_4 has leak-protected and anti-migration functions. Mixed with proper thickening-time adjustor, the slurry could meet the operating standards.

SYJ_4 can be applied to API oil_well cement. It can only be used by dry mixing peocess. Mixed with microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. Both fresh water and seawater can be used in the slurry. It is suggested that SWJ_4 can be used with retarder SYH-1, SYH-3etc.

Additives Filtrate Loss

Description

SYJ_7 is one kind of high molecule weight polymer mixed with some assistant materials. In cement slurry ,be able to effectively adsorption in cement particle surface,change the surface of cement particles physical and chemical properties,form a kind of cement particles in the aggregate net for node,in particle surface covered the density of macroscopic throats forming quickly filter cake,thus effectively reduce water loss of mud filter.With the agent of the preparation of the slurry have fall filter lost, and leakproof, prevent channeling and other functions,cooperate with the corresponding adjustment of the agent,can make water mud to meet the requirements of the cementing operation index.

SYJ_7 can be applied to API oil_well cement. And it can only be used by wet mixing process. Mixed with density adjustor, such as microsphere, bentonite, flyash, ilmenite, barite, it could mixed into slurry with different density,Match should be fresh water or seawater slurry water, sea water use should be appropriately enlarging the added amount of friction reduction agent.It is suggested that SYJ-7 can be used with retarder SYH-1, SYH-3, etc

This product and application of products on the market has been compared,Mainly has the following advantages:High temperature (220 degrees), fight saturated salt water, but water soluble, add quantity is little, solid powder,To make up for the original solid drop water loss can't wet mix and high temperature resistant, liquid drop water transportation cost is high, lost to storage and add a large quantity of defects.

Pad Fluid For Cementing

Description

SYQ is a kind of Pre Flush for cementing. It is specially for improving displacement efficiency,

flushing the mud or mud cake between the pipe wall and the wall of a well. SYQ can prevent the unstable formation caving, providing weak formation and lost circulation formation with slow eclipse function. Thus,it can protect pay zone.

SYQ Pre Flush has two catalogues as SYQ-C and SYQ-G(spacer).

Retarder

Description

The SYH_3, proposed and developed latterlyadapts to cementing in mid and hight temperature condition. Under 90~220℃, it can act with the cement particle surface ,so it prevents the cement hydrating, prolongs the thickening time of slurry.SYH_3 has very well compatibility with other additives in cement slurry. There is no effect on cement compressive strength when curing temperature is higher than BHCT. There is certain effect on cement compressive strength when curing temperature is lower than BHCT.

SYH_3 can be applied to API oil_well cement. Mixed with density adjustor, such as microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. It is suggested to be used together with SY series fluid loss control agents and dispersant SYJZ_1, So as to get cementing slurry with excellent combination property.

Defoamer For Oil Well Cement

Description

SYX_1 is a kind of organic aliphatic defoamer, it is a kind of water insoluble oil, which is transparent or yellowish. It can eliminate the foams that produced by polymer compound and surfactant, and has good function of defoaming to all kinds of slurry. SYX-1 is compatible with all kind of additives.
