Laboratory Experimental Research on In Situ Combustion of Thick-Massive Super Heavy Oil Reservoir

Conference paper
Part of the Springer Series in Geomechanics and Geoengineering book series (SSGG)

Abstract

Taking the W block in Liaohe oilfield as the subject of research, experimental devices of physical simulation for in situ combustion are used to test combustion parameters and study fire-flooding-assisted gravity drainage. According to the test results of threshold temperature of crude oil and other combustion parameters, this block meets the conditions for fire flooding development. The physical simulation results show that establishment of initial temperature field, cultivation of drainage channel pattern, and the external coking plugging of horizontal wellbore guarantee the stable oil drainage of gravity fire flooding. The optimal design of perforating interval in gas injection wells, the layout of exhaust well, and the control of injection, production, and discharge are the critical measures to avoid combustion front breakthrough in horizontal production well and realizing the gravity fire-flooding process.
