Sedimentary characteristics of turbidite fan in upper submember of Es3 in the third area of Shanghe Oilfield, Huimin Sag
Online published: 2014-06-06
Based on core observation, log data, thin section analysis and regional geological background, this paper studied the rock types, grain size characteristics and sedimentary structures of turbidite fan of upper sub-member of the third member of Shahejie Formation in the third area of Shanghe Oilfield. The result shows that the rock types mainly include siltstone, fine sandstone and argillutite. Erosion surface, gloove cast, grading bedding, convolute bedding, flame structure and small-sized contemporaneous fault are mainly developed. The granularity analysis result shows typical features of turbidite deposit. Middle fan which is dominant and outer fan are recognized, which can be further divided into channel, interchannel, channel lateral margin, and outer fan mud. The vertical sedimentary sequence, sedimentary facies distribution and evolution and the controlling factors were analyzed.
