Composition, Molecular Structure and Mechanism Analysis of Viscosity Formation of Bohai Heavy Oil
By characterizing the composition and molecular structure of heavy oil in LD-5 oilfield, a typical heavy oil field in Bohai Sea, the mechanism of high viscosity of heavy oil in Bohai is re-vealed, and the viscosity reduction method for its molecular composition characteristics is studied with molecular simulation technology. The research shows that the high content of heavy components in Bohai heavy oil and the heavy components containing molecules with long side chains and multi-ring structures are the main reasons for its high viscosity. The molecular simulation results show that the addition of surfactants can disperse and reduce the three-dimensional accumulation of heavy com-ponents, achieving the purpose of reducing the viscosity of heavy oil.
