低温低压油藏注空气提高采收率耗氧初探
Preliminary study about oxygen consumption of injecting air into low-temperature and low-pressure reservoir
摘要
Abstract
The Ganguyi blocks is the main production area of Yanchang oilfield, the main developing oil layer is Chang 6 reservoir with low pressure, low permeability and low temperature characteristics. Since 2007, the air-foam enhance oil recovery technology is used, and it achieved good results. An instrument is used to simulate the oxygen consumption of injecting air into a reservoir with 30℃ and 6 MPa, and the oxygen content diminishes with index, it will drop under the explosion limit after 80 days, and it can run out if the time is long enough, the law is verified in field test based on a low-temperature and low-pressure reservoir. So, the air-foam enhance oil recovery technology can be used in the low-temperature and low-pressure reservoir.关键词
