人们已经找到一种在临界脱气状态下采油的有效方法，即设计一种开采薄的过缘油层的新技术。并对该项新技术应用于在油藏含油厚度和油藏性质上不同的四种类型的薄油层的有效性进行研究。研究结果表明，新技术提高了原油采收率。这项新技术能在油田整个开采期内有力地增加原油的累积产量。 An effective way to recover oil in critical degassing conditions has been found, namely, to devise a new technique for the exploitation of thin, marginal oil layers. The effectiveness of the new technique applied to four types of thin reservoirs, which differ in reservoir oil thickness and reservoir properties, is studied. The results show that the new technology improves the recovery rate of crude oil. This new technology can effectively increase the cumulative production of crude oil throughout the field.
