Abstract:

In-situ combustion in Liaohe Oilfield becomes mature gradually after trial tests. This paper, based on in-situ combustion tests in two different heavy oil reservoirs, compares their optimized design in bedded and thick-bedded heavy oil reservoirs, which helps understand the mechanism of in-situ combustion and provides reference for application of in-situ combustion in Liaohes heavy oil reservoir. As its application extends from bedded reservoir to thick-bedded, a combination of vertical plus horizontal wells has been used in extracting thick-bedded heavy oil reservoirs, and comes into mature and optimization.

Key words: heavy oil reservoir, in-situ combustion, optimized design, comparison, Liaohe Oilfield
