Product Introduction
Asphalt dispersants can maintain the dispersed state of asphaltene in crude oil to prevent further coagulation of asphaltene. The advantages of this product include:
Reduce the generation of oil sediment and facilitate the transportation of extracted fluids.
Relieve blockages in pipelines and equipment caused by asphaltene deposition, and improve production continuity.
Reduce the viscosity of the oil phase and lower the pumping pressure.
Technical Indicators

Application
This product is mainly used to solve problems such as blockage and high pressure caused by asphaltene deposition in wellbore and pipeline transportation; Based on the on-site situation and the nature of the oil, it is recommended to add 300-1500ppm of medication.
Classic case
Due to the high asphalt content in a single well in a certain block in the Middle East, the deposition and precipitation of asphalt in the pipeline are caused by the decrease in temperature, resulting in an increase in pipeline transportation pressure and low transportation efficiency. Deshi has developed asphalt dispersants LQY-01 and LQY-03 with efficient dispersion effect, which can effectively solve this problem. Through customer on-site screening tests, LQY-03 asphalt dispersant has been applied in the Middle East since May 2023, and customer feedback has shown excellent results. Currently, it is continuously supplied and used.
