Setting Accelerator For Oil Well Cement

Description

SYC_1 composed by kinds of chemicals, can shorten thickening time. Under low temperature, SYC_1 can effectively enhance cement stone’s early strength and final strength, has no negative affects to final strength or high temperatures strength development. It can be either dry blending or wet blending according to the field situation.

SYC_1 is compatable with other cement additives in slurry and can be applied to any class of API oil well cement. It is suggested to be used together with SW series fluid_loss control agents and SY series dispersants, so as to get cementing slurry with low dehydration, quick setting, early strong compressive strength, low density and so on .

Drilling Fluid Loss Additives

Description

SWJ_6 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 SWJ_6 has leak_protected and anti_migration functions. Mixed with proper thickening_time adjustor, the slurry could meet the operating standards.

SWJ_6can 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.

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.

Brake Fluid Additives

escription

SYJ_1 is one kind of high molecule weight polymer mixed with some special materials. It can stick on the surface of cement particles and modify the physical and chemical function of cement particles. So it forms a net aggregate with the cement particles as its knots. It narrows the micro porous and forms a compact filter cake, so it can control the fluid loss effectively. The slurry which is applied SWJ-1 has leak-protection and anti-migration functions. Mixed with appropriate thickening-time adjustor, the slurry could meet the operating standards.

SYJ_1 can be applied to any class of API oil_well cement. It can be used by wet mixing and dry mixing. Mixed with extender material, such as microsphere, bentonite, flyash, ilmenite, barite, it could be mixed into different density. Both fresh water and seawater can be used in the slurry. When it is used with seawater, we must increase the quantity of the dispersant. It is suggested that SYJ-1 can be used with retarder SYH-1, SYH-3etc.

Early Strength Admixture For Oil Well Cement

Description

SYZ_1 , a kind of early strength admixture without chlorine, is hydrosoluble powder. It is suitable to the low temperature shallow well and the adjustment well .It is suitable to be used in the low density slurry. It may greatly reduce the thickening time, enhances early strength , improve cementing quality and shorten cementing time. The cementing slurry mixed with SYZ_1 is more steady, does not have sedimentation and eduction, reduce free water and enhances cement stone compressive strength. Simultaneously cement stone will slightly expanded wjem using and there is no negative effect on stone strength under the high temperature

SYZ_1 is compatable with other cement additives in slurry and can be applied to any class of API oil well cement. It is suggested to be used together with SY series fluid_loss control agents and SY series dispersants, so as to get cementing slurry with low fluid loss, quick setting, early strong compressive strength, low density and so on .

Dispersant For Oil Well Cement

Description

SYJZ_2 is a kind of organic compound that synthesized by sulphonation of methanal and acetone. It can be used as an efficient solid dispersant of cementing slurry. Between 30_150℃ ,it can stick on the surface of cement particles, produce absorbent electric double layer, disperse slurry, and lower the initial consistence of slurry, so it optimizes the rheological behavior of slurry. At atmospheric temperature, it slightly prolong the slurry thickening time,and disperse the slurry obviously. There is no harmful effect on the other comprehensive property of slurry.
