The secondary gas harmless treatment is developed in Liaohe Oilfield to solve the issue of secondary gas emission. It applies the combination technology of low pressure and pressure adsorption to realize the separation of secondary gas. The CH4 separated is used as oil field fuel,and CO2 is used to recycle oil flooding,which not only solves the problem of secondary gas emission,but also realizes energy saving and environmental protection.%为解决次生气排放问题,开发了辽河油田次生气无害化处理技术.主要应用低压变压吸附等组合技术来实现次生气的分离.其中分离出的CH4用作油田燃料,CO2用于回注驱油.这样既解决了次生气排放问题,又实现节能、环保的要求.
