Sodium Formate for Oildrilling
Product Features
High purity
The purity of sodium formate for oildrilling is as high as 98% or more, with low impurity content.
High solubility
The product dissolves quickly at room temperature and can be completely dissolved in water within 30 seconds without residue.
Low Corrosiveness
This product does not contain chloride ions, and its corrosion rate is much lower than that of traditional drilling salts. Its corrosion to underground metal casing and equipment is less than 0.005g/m²·h.
High density adjustment capability
The density of sodium formate used in oil drilling can reach 1.58 g/cm³, which can effectively adjust the density of drilling fluid to the range of 1.2~1.6g/cm³. It is suitable for the construction of medium-deep wells and high-pressure wells, and helps prevent well control problems such as blowouts and well wall collapse.
Frequently Asked Questions
Q: What is the working principle of sodium formate for oil drilling?
A: Sodium formate improves the inhibition of drilling fluid by adjusting the ion balance in drilling fluid, prevents shale hydration and expansion, and stabilizes the well wall.
Q: What are the main applications of sodium formate in oil drilling?
A: Sodium formate is mainly used to prepare water-based drilling fluid. It can be used as a shale inhibitor and filtrate reducer, and can also improve the rheology of drilling fluid.
Q: How to clean the residual sodium formate in drilling equipment?
A: The surface of the equipment can be rinsed with clean water. For stubborn residues, it can be wiped with a neutral detergent and then rinsed with clean water.
Q: How to install and use sodium formate in drilling fluid?
A: Sodium formate needs to be added slowly to the drilling fluid circulation system in proportion, stirring while adding to ensure that it is fully dissolved and dispersed.
Q: What should be paid attention to when storing sodium formate?
A: Sodium formate should be stored in a dry and ventilated warehouse, away from fire and heat sources, to avoid moisture and agglomeration, and should be stored separately from strong acids.
