DRY COMBUSTION PHYSICAL MODELING OF IN-SITU COMBUSTION

Using combustion tube physical modeling in lab, we have tested the Xinglongtai formation of Huan block 127 in liaohe oilfield and researched feasibility of using fire flooding technique in Liaohe oilfield. The experimentation analyzed the properties of the output liquid and the constitutes of the output gas,and researched the influence of in-situ combustion temperature distribution and gas injection parameters, providing basic parameters and control conditions for the research of numerical simulation.The result of the experimentation indicate that the Xinglongtai formation of Huan block 127 can be ignited at the temperature of 340℃ and can burnt at definite gas injection velocity, the recovery efficiency in laboratory can reach to 83.1 per, the experimentation and the research provided theories for the application of this technique in oil-field.
