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.
