Is it necessary to use potassium formate drilling fluid for drilling operations?

 The existence of everything is related. Drilling fluid is to improve drilling efficiency and reduce accidents and mining damage to the environment. Potassium formate's inhibitory properties, anti-temperature and anti-pollution properties are actually used in many places nowadays. The use of potassium formate mud is conducive to improving polymer stability, stabilizing shale, reducing damage to rock formations, and ensuring that drilling, completion, and oil wells are in optimal working conditions.


Drilling fluid is the circulating flushing medium used in the hole during drilling. The effect of the density of potassium formate drilling fluid is actually more reflected in its hydrostatic column pressure. The pressure generated on the ground mainly comes from the three aspects of collapse pressure, pore pressure, and collapse pressure. So when we are working, if the pressure is over nature, it will cause lost circulation.


Under normal circumstances, depending on the drilling method, the pressure may be greater than or less than the pore pressure. In other words, the pressure cannot be made too small to cause the well to collapse. If we can do what the following editor talks about, this situation will be effectively reduced. When using potassium formate drilling fluid, it is necessary to carry the drilled cuttings to the ground, which means that the excavated materials need to be transported out. In this way, it will not easily cause blockage, so that the situation of well collapse will gradually decrease.


After using potassium formate drilling fluid, it actually has many functions. The main effect of using it is that it will be reflected in the pressure of the hydrostatic column. To put it more simply, the pressure of the dense hydrostatic column will naturally increase, and then it will be for the well wall and bottom The pressure generated is naturally greater.


For the generated pore pressure, the pressure actually needs to be lower than the pressure entering the well in the surface fluid. If everyone does not care enough about this situation, the rupture pressure, whenever the pressure is greater than this value, the well wall will be leaked and lost circulation will occur. Potassium formate drilling fluid can also rely on the liquid column pressure to balance the air pressure, prevent blowouts, stabilize the well wall and prevent drilling collapse. This will also be of greater help to everyone who wants to maintain the well wall.

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
