CAS NO: 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
