How to distinguish genuine and fake potassium formate drilling fluid? The manufacture tells you

 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 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 drilling fluid? The manufacture tells you.

When potassium formate is used in 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 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.
