Their distribution of deposition control lithology subtle trap, die - out around paleo - uplift the distribution of subtle traps in the slope, subtle trap forms along faults and above and beneath unconformity boundary. through exploring and studying in huanghua depression many years, we gradually summarize a series of methods and technologies for subtle trap exploration, they are precise stratigraphy correlation on the basis of sequence stratigraphy, including micromarker correlation, element logging, high frequent cycle stratigraphy and precise sequence stratigraphy, besides conventional biography stratigraphy, logging correlation. through using facies analysis method, the type and distribution of reservoir are determined
在黃驊坳陷通過多年的摸索和引用，逐漸形成了一套系統的隱蔽油氣藏的研究方法和技術，它們是以層序地層學為代表的地層精細劃分方法，用來解決地層劃分及歸屬問題，除常規的生物地層學、巖電特徵對比方法外，創新性的運用了包括微標志層劃分方法、元素測井方法、高頻旋迴對比方法及精細層序地層劃分方法等四種精細地層劃分方法。 -
