Potassium Formate for Oildrilling
potassium formate for oil drilling
Product Features
High-purity process
Potassium formate for oildrilling uses food-grade formic acid and ion membrane potassium hydroxide to react, and after multi-stage purification, the purity is ≥99.5%, with few impurities, ensuring stable drilling fluid performance.
Efficient inhibition of shale
Potassium formate for oildrilling inhibits shale hydration through ion exchange, making the expansion rate ≤15%, reducing well wall collapse, and improving drilling efficiency by more than 30%.
Adaptable to multiple geologies
It is compatible with complex formations such as sandstone and salt rock, without the need to frequently adjust the drilling fluid formula, reducing operation interruptions.
Frequently Asked Questions
Q: What is the working principle of potassium formate in oil drilling?
A: Potassium formate stabilizes the well wall and reduces damage to the oil and gas layer by controlling the viscosity and filtration loss of the drilling fluid, while inhibiting the hydration and expansion of shale.
Q: What are the main applications of potassium formate in oil drilling?
A: Potassium formate is mainly used to prepare water-based drilling fluids, which are suitable for deep wells, high-temperature and high-pressure wells and well sections prone to collapse. It can also be used as a completion fluid additive.
Q: How to clean drilling equipment with potassium formate?
A: Potassium formate is easily soluble in water. After drilling, the equipment is flushed with water. Potassium formate dissolves with water and can effectively remove residues attached to the equipment.
Q: How to install and use potassium formate in drilling fluid?
A: Potassium formate needs to be mixed with other drilling fluid materials in proportion, fully dissolved by stirring equipment, and pumped into the drilling circulation system for use.
Q: What should be paid attention to in the storage of potassium formate for oildrilling?
A: Potassium formate for oildrilling should be stored in a dry, ventilated warehouse, away from fire and heat sources, to prevent moisture and agglomeration, and should be stored separately from strong acids.
