How to distinguish genuine and fake potassium formate for high quality oil drilling fluid?

 Regarding the impact of modern drilling fluids on the environment, it is recommended that everyone must pay attention to these, these are directly related to the human living environment. The oil drilling fluid penetrates into the formation with potassium formate, and the flow resistance is large, which not only inhibits the hydration, dispersion and expansion of the clay, prevents the formation from shrinking, but also does not interfere with the electrical measurement. It has light corrosion and avoids pollution to the oil layer. How to distinguish genuine and fake potassium formate for high quality oil drilling fluid?


When potassium formate is used in oil drilling fluid, it is generally selected to purchase solids, which is convenient for transportation and more convenient for the preparation of drilling fluid system. Taking potassium formate solid as an example, how to distinguish:

1. The solid potassium formate is white crystal, easy to absorb moisture, and has reducibility. (Chuandong Chemical Group has ensured that potassium formate does not cause any problems in the preparation of drilling fluid systems. When potassium formate is shipped from the factory, no anti-caking agent is added and vacuum packaging is used.) It should be noted that some anti-caking agent may be used. There are other substances in it, which can not meet the requirements of drilling use.

2. The potassium formate aqueous solution is a colorless transparent liquid, the specific gravity of the saturated solution is 1.58 g/cm3, the saturation concentration of potassium formate can reach 76%, and it dissolves quickly. Some impurities will appear if the saturated potassium formate solution is not reached.

3. The content of high quality potassium formate (solid) ≥96%. Not to mention the content, can you use it with confidence even if you can't reach the basic quality indicators?

4. The solubility of high quality potassium formate per 100 ml of water at different temperatures: 313g/10 ℃; 337g/20 ℃; 361g/30 ℃; 398g/40 ℃ 471g/60 ℃; 580g/80 ℃; 658g/90 ℃.

5. Potassium formate drilling fluid is a kind of inorganic brine drilling fluid system. It is a non-toxic and easily biodegradable drilling fluid. There is no pungent odor when distinguishing its true and false.


For the oil drilling industry, chemical methods are mostly used. The main role in drilling and completion fluids is potassium ions, which can be completely dissociated. When the same amount is added, the effective K concentration is higher than that of potassium chloride, and there is no pollution of anionic chloride. The surface tension of the filtrate is significantly greater than that of potassium chloride drilling. In the completion fluid system, the flow resistance into the formation is large, which not only inhibits the hydration, dispersion and expansion of the clay, prevents the formation from shrinking, but also does not interfere with the electrical measurement. It has light corrosion and avoids pollution to the oil layer. Therefore, when purchasing potassium formate, you must find a formal company to avoid unnecessary losses.

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

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
