The manufacturer tell you what drilling problems can potassium formate drilling fluid solve?

 As oil and gas exploration and development tends to be deeper and more complex, the pressure difference is less than the drilling pressure to maintain the stability of the borehole wall, resulting in the occurrence of complex accidents such as downhole leakage, blowout, collapse, and stuck, and the problem of prolonged drilling cycle. The new drilling fluid potassium formate provides convenience for on-site operators' various operations, overcomes many difficult problems under complex geological conditions, and breaks a big bottleneck for drilling speed and efficiency. Today, the manufacturer Chuandong Chemical will tell you about the complex drilling problems that can be solved with potassium formate in drilling fluids.


Potassium formate in drilling:

(1) The use of potassium formate without adding or adding a small amount of solid weighting agent can make the drilling fluid have a higher density and a larger density adjustable range (1.2-2.3g/cm3), which is easy to achieve solid-phase drilling or Low solids drilling.

(2) Low viscosity, good fluidity, and small friction pressure loss, suitable for drilling small holes and formations that are easy to lose.

(3) Strong inhibition, stable shaft wall and regular bore diameter.

(4) The contact of potassium formate with the formation water does not produce any sediment, and the damage to the reservoir is small.


Environmental aspects of potassium formate:

(1) Potassium formate has low biological toxicity, is harmless and non-toxic to human body, and has little effect on aquatic community.

(2) It is easily biodegradable and has low bioconcentration.

(3) It is less corrosive to metals and rubber.

(4) Recyclable and reusable.


Recycling of potassium formate:

How to deal with waste drilling fluids has been an environmental protection problem for many years in geological exploration of oil and gas fields and engineering drilling. Since most of the drilling fluids currently used cannot be recycled, the usual treatment method is still on-site discharge, only very few Partially separated and cured.


Potassium formate drilling fluid is a new type of drilling fluid that is recyclable and reusable. Through recycling, not only can the impact on the environment be reduced, but also raw materials can be saved, and the cost of drilling fluids can be reduced by chemical separation and recovery tests. The recovery rate of potassium formate drilling fluid is over 60%, and the recovery effect is good.


Through the recovery, the potassium formate solid-phase drilling fluid can be prepared for the second time. This can also greatly reduce the cost of drilling fluid raw materials.

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
