How to make salt resistant bentonite?
According to the salt content, brine drilling fluid can be divided into ordinary brine drilling fluid, saturated brine drilling fluid and sea water drilling fluid. The main component of seawater is sodium chloride, whose salinity is in unsaturated state, and the sea water drilling fluid is treated with ordinary brine drilling fluid.
Bentonite ore - Analysis (CEC sediment concentration, blue absorption) - coarse crushing - adding alkali ingredients - water, crude sodium - - heating fine sodium - - detection of bentonite (1 grams of soil is not 3 grams of soil) > 90ml/g---- semi-finished products
General brine or sea water drilling fluid: product +4%GS11+0.5%, salt resistance thickening agent - crushing - --- testing - finished productsSaturated brine drilling fluid: product +5%GS11+1%, salt resistance thickening agent - crushing - --- testing - finished products
