PHYSICAL SIMULATION EXPERIMENT OF AIR-INJECTION EOR IN LOW-PERMEABILITY OIL RESERVOIRS
摘要
Abstract
In order to determine the feasibility of applying light-oil air-injection EOR technology in Beizhong Sub-sag of Hailar-Tamsag Oilfield, the contrast experiment of the displacement efficiency of water flooding and air-injection displacement, slime tube low-temperature oxidation test of air-injection displacement, combustion tube high-temperature oxidation test of air-injection displacement and swelling experiment of produced gas are designed according to main technological theory of air injection. The study shows that the displacement efficiency of air-injection displacement is 22. 19% higher than that of water flooding. Low temperature oxidation may occur in reservoirs after air injection, and moreover the oxidation may accelerate with the increase of temperature. The kinetic parameters of low-temperature oxidation reaction, I. E. Activation energy and pre-exponential factor, are obtained. The component change relation of produced gas and the change of solubility, viscosity, density and volume factor of produced gas after its dissolve in crude oil are obtained. The technical principle of air-injection low-temperature oxidation oil recovery is verified, all of which provides the reliable evidence for the field operation of air-injection oil recovery technology in light-oil reservoirs.关键词
