Chrome lignosulfonate is one special kind of lignosulfonate that used as drilling mud thinner . It can resist high temperature and salt; also can easily used with other mixture together.It is mainly suitable to drilling deep well on the condition of complex geology and high mineralization . A. Characteristics 1. Aiti-high temperature. The resistance to high temperature can reach 150to160, and the performance of mud can stay the same during the 16 hours. 2. Anti-salt. The performance of 2% salt water mud is better than fcls (ferrochrome lignosulfonate). 3. Dilution .The dilution rate is better than fcls when used in the same mud. 4.It is suitable to all kinds of dispersed mud due to the excellent thinning property and powerful anti-electrolytes. B. Application: Chrome lignosulfonate can be added into drilling fluid in the form of aqueous solution or powder. To adjust ph to 10.0~10.5, the recommended dosage of thinner should be 0.5~1.0%(w/v).

Fcls products is produced in new technology innovation according to the enterprise standard (q/mhlhg15-2013) . The performance is similar to the conventional fcls, but because of its low cost of production, the price is also reduced correspondingly, through which we can better serve our customers. A. Characteristics 1, fcls is suitable to all kinds of dispersed mud, due to the excellent thinning property and powerful anti-electrolytes capacity 2. Be effective at temperature more than 150~160. It can be better effective when cooperating with lignite derivatives. B. Application Fcls may be added into drilling fluids in the form of aqueous solution or powder. To adjust ph index to 9.5~10.5, the quantity of thinner should be 0.5~1.0 %. C. Package The net weight of each bag is 25kg. With paper-plastic complex valve bag

MH-I chrome-free lignosulfonate is a thinner used in drilling fluid and fluid loss control agent. It is characterized by resistance to high temperature and electrolyte, no poison and being used with other admixture agent etc. It is mainly suitable to the all kinds of dispersed muds. A . Characteristics 1.With excellent thinning performance and filtration control capacity , the mud performance of fresh water is better than salt water mud. 2. Anti-high temperature can reach 150 , , it can cooperate with other admixture agent. 3. It's a security product, non toxic, non corrosive, non flammable and explosive materials. It`s safe to use and causes no pollution to the environment. B . Application: 1.Mh-i chrome-free thinner can be added into drilling fluids either in the form of solution or powder. After that, the ph of drilling fluids will decrease a little, so sodium hydroxide should be added to keep ph between 10.0~10.5. 2.As a thinner , the recommended dosage is 1.0%(w/v) in fresh water mud , 1.5%(w/v) in salt water mud

Thinning performance Test results indicate the thinning performance in fresh water based mud under normal temperature is comparable to ferrochrome lignosulfonate (fcls). At elevated temperature, it performs better than fcls in either fresh water or salt-water based mud, particularly the later. The product is suitable for use in drilling under complex geological formation, in water with high tds, or in offshore drilling. 2. Good fluid loss control properties Its major advantage is the thinning effect in drilling mud with high solid content, and simultaneously controls the fluid loss. Its fluid loss control action is better than fcls and the mud cake formed is smooth and compressible, thus beneficial for well bore protection and fluid loss reduction under high-pressure condition. 3. Higher retention of solid The product has improved solid retaining capacity due to its excellent thinning properties. Even when the mud is mixed with large quantity of clay while drilling, the rock scarps can still maintain good mobility. In addition it is capable of withstanding contamination by calcium, magnesium and sodium electrolytes, making it an ideal thinning agent for heavy weight mud. 4. Recommended dosage For salt water and fresh water based mud, a range of 0.5 to 1.0% is recommended depending on the specific conditions. Under special situations such as high solid and metal electrolytes content, a slight increase in dosage is recommended but not to exceed 2.0%. 5. Packing It is packed in 25 kg net weight moisture proof multi-wall paper bags, with pe film inside. Other size packing is also available on request.

Chrome-free lignosulfonate is a drilling mud thinner produced by multi chemical reactions followed by drying of natural high molecular weight compound, organic material and harmless metal ions. The product contains no Chromium heavy metal and is ideal for use in drilling at densely populated area and offshore.
