Uses : for Drilling Fluid

Product description: Applications:

The low and medium temperature resin asphalt for drilling fluid is a kind of chemosynthesis agent which is processed from resin polymer, asphalt and multi-surfactant. It is used mostly to enhance the reducing filtration and anti-caving capacity of drilling fluid under low and medium temperature. The DLF-50 can efficiently block formation crack. The DLF-50 has some good performance, such as salt resistance, inhibitory and fluid loss performance. From normal temperature to 120 ℃, the DLF-50 can keep borehole wall stable and reduce friction coefficient of the mud cake, and the drilling fluid which including the DLF-50 has steady performance, convenient operation and evident effectiveness.
The recommended concentration for drilling fluids is 2 percents. The drilling fluid will deserve better property, such as rheological property, filtration loss control, plugging property and so on.
