Drag reducer

With the increase of the viscosity of the fracturing fluid, the pipeline friction and the power loss of the pump also increase. In order to effectively utilize the efficiency of the pump and reduce the friction of the fracturing fluid, drag reducer in oilfield is usually carried out using the fracturing fluid. 

Commonly used drag reducer for water-based fracturing fluids include polyacrylamide and the derivatives of drag reducer, polyvinyl alcohol (PVA), vegetable gum and its derivatives and various cellulose derivatives.

This series of drag reducer include sand carrying of the drag reduction agent is high-molecular-weight linear polymers--polyacrylamide. 

During the synthesis process, hydrophilic groups are introduced into the main chain of drag reducer's molecules through a special production process, making sand carrying of the drag reduction agent more easily dispersed and dissolved in water and reducing friction; if an appropriate amount of polymer drag reducer is added to the water, the pumping friction can be reduced by more than 70% compared to the friction of clean water.

There are huge market share in drag reducing agent market and has two types of drag reducer:Sand carrying drag reducing agent & Acidification thickening liquid.
