Production Performance of In-Situ Combustion in Heavy Oil Reservoir after Steam Injection

Abstract

Abstract: As a succeeding development process following steam injection (huff and puff, steam drive) in heavy oil reservoir, in-situ combustion has been used in WellBlock HQ-1 of Karamay oil field in order to further enhance oil recovery. This paper studies the effect of ground secondary water on in-situ combustion process, presents five production stages and their production performances of producers by means of reservoir numerical simulation and physical modeling methods, and analyzes the three different occurrences and their formation mechanisms in early responses. These will be of significance of grasping the fire-flooding performance under similar reservoir conditions.

Key words: Xinjiang, heavy oil reservoir, in-situ combustion, steam injection, production performance
