I. Product Brief
Multifunctional emulsion SDJ-2 for drilling fluid is a product formed by colloid chemical method under certain process conditions with non-ionic surfactant, paraffin and lubricating oil as the main raw materials. Functional emulsion SDJ-2 forms a shielding zone with extremely low permeability near the well wall, so that the solid phase particles and filtrate in the drilling and completion fluid can enter the deep part of the bottom layer, thereby avoiding the impact of drilling fluid and completion fluid on oil and gas channels.Feature: It plays a good role in protecting the oil and gas layers. At the same time, because the temporary plugging agent is paraffin, it is easy to flow back, And will not cause damage to the oil and gas layers.
