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.

Crystal Expanding Agent For Oil Well Cement

Description

SYP_2 the grid expansion agent is the company launched a new oil well cement inflationseveral kinds of high performance crystal materials mixture.In cement slurry ,crystal materials can be hydration reaction,its hydration products for the expansion of the main source isHydration products crystal inflation,on the one hand can compensate for the mud (stone) of water volume contraction and generate volume expansion,in favour of the channeling;At the same time ,still can compress cement pore and improve pore distribution stone,to enhance the strength and reduce the purpose of permeability;In addition,in the limited state also can produce prestressed,improve cement ring and the compressive strength of plastic pick up,help to prevent the ring empty space and the stone and the corrosion of the cement the casing of casing damage rate, control restrain circulation.

SYP_2 the grid expansion agent in accordance with the requirements of the API for oil well cement at all levels.The scene to use dry mixing,Recommend and SY series drop water loss and dispersant use compatibility, etc,to get meet the requirements of the cementing with low water loss, high inflation, high strength properties of slurry.

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.

SYJZ_2 is compatible with other cement additives in slurry and can be applied to API oil well cement. It is suggested to be used together with SYseries fluid-loss control agents and retarder, so as to get cementing slurry with excellent combination properties.

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).
