What are the advantages of potassium formate solid-free drilling fluid?

 As we all know, mud is the blood of drilling, and mud is also the most likely to cause pollution. Drilling fluid is also an important part of petroleum drilling. The solid-free drilling fluid has the advantages of small density and low viscosity, which is beneficial to increase the drilling speed and is gradually favored. Potassium formate drilling fluid is formed in order to adapt to the technical development requirements of modern drilling. What are the advantages of potassium formate solid-free drilling fluid?


In order to avoid the damage of the solid phase in the drilling and completion fluid, the development of a solid-free completion fluid, because it does not contain a solid phase, potassium formate solid-free drilling fluid has the following unique advantages.

(1) Increase the drilling speed, extend the life of the drill bit, and shorten the production cycle.

(2) Thinning the mud cake and reducing the stuck rate of differential pressure sticking and logging tools.

(3) Reduce the viscosity, which is good for high-pressure injection and reduce the agitation pressure.

(4) Reduce the damage of oil and gas layers.

(5) Stabilize the performance of drilling fluid, simplify maintenance and reduce the cost of drilling fluid.

(6) Reduce the density and reduce the possibility of lost circulation.


With the increasing environmental awareness in the world and the increasingly strict environmental protection regulations, the impact of completion fluids and their waste on the environment has aroused widespread concern in the environmental protection community, the petroleum business community, and many publics at home and abroad. Environmental protection is also a new topic in the research work of the drilling and completion industry, because potassium formate is non-toxic, easily biodegradable, and will not cause pollution and harm to the natural ecological environment.

The factory tells you food grade sodium tripolyphosphate/STPP requires heavy metal purification

Condiments, meat products, edible oil, dairy products, drinks, etc. are all necessities of daily life. Some food additives will be used in the production and processing process. The use of additives also makes people more concerned about "safety on the tip of the tongue".  Sodium tripolyphosphate/STPP  is widely used in food additives. Chongqing Chuandong Chemical Group will show you the main applications of sodium tripolyphosphate/STPP in the food industry: 1. Food grade sodium tripolyphosphate is used in meat products, fish sausage, ham, etc., which can improve the water holding capacity, increase the cohesiveness and prevent fat oxidation; 2. For fruit drinks and cool drinks, it can improve the juice yield, increase the viscosity and inhibit the decomposition of vitamin C. 3. It can prevent discoloration, increase viscosity, shorten fermentation period and adjust taste when used in soybean paste and soy sauce. 4. For ice cream, it can improve the expansion capacity, increa

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho

Non-antibiotic growth promoter potassium diformate helps pig industry return to its essence

  The high profitability of the pig industry will not last, and the future development of the industry still needs to return to the essence of pig raising. The non-antibiotic growth-promoting agent   potassium diformate  helps return to the essence of breeding and helps control the cost and quality of the pig industry. Biosecurity has become the access condition of today's pig industry. Potassium diformate has the following functions and functions to return the essence of pig farming to the breeding industry: (1) Adjust the palatability of feed and increase animal feed intake. (2) Improve the environment of the animal's digestive tract and lower the pH of the stomach and small intestine. (3) It has anti-bacterial and growth-promoting effects. The addition of potassium diformate can significantly reduce the content of anaerobic bacteria, Lactobacillus, Escherichia coli and Salmonella in each segment of the digestive tract. Improve the resistance of animals to diseases and reduce
