人工地震增油技术在克拉玛依油田中的应用

Application of Artificial Earthquake Stimulation to Karamay Oilfield

人工地震增油技术作为三次采油的新技术,以其见效快、效率高、不污染油井、不影响油田正常生产等优点而受到日益广泛的重视。该项技术的基本原理是,利用地面可控震源产生的地震射线作用于地层产生高频射线,使地下岩体产生裂隙而裂解,形成新的油气运移通道,进一步改善储集层的性能和原油的物理化学性质,从而达到增产原油的目的。在克拉玛依地区三次采油实施中取得了非常显著的效果,这是一项值得推广的增产措施。

As a new technique for tertiary oil recovery or EOR, artificial earthquake stimulation is increasingly valued for its quick response, high efficiency, non-pollution to well and influence-free on regular production of oilfleld. Its principle is that the using vibroseis, the high frequency ray produced from seismic ray which acts on the strata may allow to produce cracks or fractures and to form some new channels for hydrocarbon migration, thus further improving the reservoir quality and physiochemical property of crude oil for the purpose of increasing production rate. This paper introduces the very obviously practical results using this stimulation to Karamay area for EOR performed by Xinjiang Oyasa Mineral Exploration Company Ltd. It is indicated that the artificial earthquake stimulation is worth popularizing in the future.
