A Study Of The Tiny Sedimentary Facies Of The Group Of Changxing And Feixianguan In The Area Of Linshui-Yubei

The areal geology, sedimentary facies and sequence stratigraphy analysis, single well sedimentary facies and sequence stratigraphy, lithofacies paleogeography are comprehensively researched by using multi-data of Linshui-Yubei area, which include areal geology information, lab analysis data, well-logging data and analysis report, and a great deal of scientific research literature etc. According to the abundant geology data, the paper study on using the classical sequence stratigraphy theory and technique of the representative by P.R Vail, according to the systems tract in the third sequence, respective to workout the change direction chart by every systems tract in the group of Changxing and Feixianguan, include stratum thickness chart, grainstone chart and dolostone chart. According to these charts and single well sedimentary facies and contrast section sedimentary facies analysis, combine areal conformation backdrop and evolvement character, workout the sedimentary facies distributing chart by every systems tract in the group of Changxing and Feixianguan, discussed sedimentary facies developed in different systems tract in-depth by geometry shape, plane distributing, evolvement character, and the connection with reservoir, in order to more clear the disciplinarian of avail zone and reservoir plane distributing established foundation.
