| Abstract: |
| According to the comprehensive analysis of the well logging and cores and available data, it is indicated that the Middle to Lower Members of Silurian Kepingtage Formation is not lacked as the previous viewpoint in the central and southern parts of Shuntuoguole, Tarim basin. The Lower Member of Kepingtage Formation is proved to exist by the characteristic marks of sedimentary facies. Two kinds of sedimentary facies, the wave-controlled shore and the tidecontrolled shore facies, develop in the Lower Member. And therefore, the shoreface, intertidal and subtidal subfacies and the associate microfacies are recognized. A gentle-slope shore sedimentation model is set up for Lower Member of Kepingtage Fm.. It is suggested that the shore facies sandstone barrier that deposited during transgression is the most favorable reservoir. |
