Abstract
In recent years, the Ch6–Ch7 deep-water gravity flow deposits of the Yanchang Formation in the Southern Ordos Basin have been characterised as sandy debris flow sediments, a modification from previ...
Highlights
The deep-water gravity flow sediments are new fields for oil and gas exploration and have attracted great attention around the world over the past decades (Li et al, 2010b,c, 2011, 2013; Lowe, 1979, 1982; Shanmugam and Moiola, 1995; Shanmugam, 1997, 2000; Zou et al, 2009)
One example is the occurrence of the Ch6–Ch7 Member sandstones of the Late Triassic Yanchang Formation in the Jinghe Oil Field of the Southern Ordos Basin
This paper studied the characteristics of deep-water gravity flow sediments and their oil bearing in the Ch6–Ch7 Members of the Jinghe Oilfield and following conclusions were made: 1. The Jinghe Oilfield located in the southern margin of the Ordos Basin has the characteristics of the foreland basin influenced by the collision between the northern Yangtze Plate and the southern North-China Plate
Summary
The deep-water gravity flow sediments are new fields for oil and gas exploration and have attracted great attention around the world over the past decades (Li et al, 2010b,c, 2011, 2013; Lowe, 1979, 1982; Shanmugam and Moiola, 1995; Shanmugam, 1997, 2000; Zou et al, 2009). Sandy debris flow microfacies, which were massive bedding sandstones, were formed during transportation.
