Do potassium formate drilling fluids require PH values?
Drilling fluid is called "blood" of drilling. In shale gas exploration in China, the wide use of potassium formate drilling fluid has made a breakthrough in deep well drilling with domestic oil-based drilling fluid technology. The PH value has no requirement for the range of potassium formate drilling fluid . The Concept of PH Value of Potassium Formate Drilling Fluid The pH value of the drilling fluid is the pH value of the drilling fluid, which indicates the acidity and alkalinity of the drilling fluid. It is equal to the negative logarithm of the hydrogen ion concentration in the drilling fluid, also known as PH. When the pH is less than 7, the drilling fluid It is acidic. When the pH is equal to 7, the drilling fluid is neutral. When the pH is greater than 7, the drilling fluid is alkaline. The pH of the drilling fluid is usually determined by colorimetry. Effect of PH on potassium formate drilling fluid PH value has a great influence on the performance of potassi...
