How about the cementing quality of potassium formate oil drilling fluid?

 Since the beginning of this year, in the face of unfavorable factors such as deep well depth, high pressure, and large temperature difference in the Southwest Work Area, the requirements for the lubrication of the drilling fluid, the stability of the wellbore and the cleanability of the wellbore are extremely high. In drilling operations, there are generally at least two cementing (production wells) and as many as 4 to 5 cementing (deep exploratory wells). Potassium formate is a new type of oil drilling fluid at present. It does not paste the vibrating screen or run slurry during drilling. It has strong inhibition, good wall-building properties, good lubricity, fast mechanical drilling speed, low cost, and good cementing effect. And other features are widely used.


The purpose of using potassium formate drilling fluid for cementing:

1. Potassium formate drilling fluid can isolate complex formations that are easy to collapse and leak, consolidate the drilled borehole, and ensure the smooth progress of drilling.

2. Provide the foundation for the installation of wellhead equipment, control wellhead blowout and ensure that the mud outlet in the well is higher than the mud pool to facilitate the flow of drilling fluid back to the mud pool.

3. Potassium formate drilling fluid can seal oil, gas, and water layers, prevent each other between oil, gas and water layers of different pressures, and provide favorable conditions for the normal exploitation of oil and gas.

4. Protect the freshwater resources in the upper sand layer from the pollution of oil, gas, salt water and other liquids in the lower rock layer.

5. After the oil well is put into production, it has created favorable conditions for the stimulation of acid fracturing.


In order to ensure the smooth construction of the well, the on-site technical team stationed in the well and enhanced drilling fluid on-site tracking services ensured smooth drilling and tripping during the construction process, without any complications, and the smooth running of the tubing in place. The potassium formate drilling fluid system is preferred, which has excellent inhibitory performance, lubricating performance, strong rock-carrying ability, and is environmentally friendly, and can fully meet the needs of the site.

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
