摘 要: 本文假定密闭取心获取的样品,其油水两相存在不确定的散失率,考虑散失率主要受岩性、物性、实验批次等的影响,采用逐步恢复法反演饱和度的散失过程,找到最优的油水综合散失率,从而形成一种新的密闭取心饱和度校正方法。对JL油田117块样品进行校正,结果表明,本文方法相比于平移恢复法等校正法更为合理有效,具有推广价值。
关 键 词: 油气田开发工程;密闭取心;含油饱和度;逐步恢复;最优化

Abstract: In this paper, it is assumed that there is an uncertain dispersion rate of oil-water phases in sealed-coring samples, and considering that the comprehensive loss rate is mainly influenced by lithology, physical property, the influence of experimental batches, etc. The dissipating process of gradual recovering method inversion saturation is adopted to find the optimal oil-water comprehensive loss rate, thus forming a new sealed coring with new saturation correction methods. For 117 pieces of samples from calibration of JL oilfield, the results show that the method in this paper is more reasonable and effective than translation recovery and other correction methods, which has the promotion value.
Key words: oil-gas field development engineering; sealed-coring; oil saturation; gradual recovery; optimization
