Gas accumulation conditions of Lower Carboniferous in Yangjiashan region of Lianyuan Sag;

Lianyuan sag is a kind of typical reformed basin, and is one of the best favorable oil & gas sags in Xiangzhong depression.

Comprehensive Evaluation on Middle and Upper Devonian Source Rocks in Lianyuan Depression in Hunan Province;

Thrust and gravity gliding structures are both developed in the west of Lianyuan depression.

In order to study the properties of ground structure, underground structure and their tectonic evolution in Lianyuan depression, ground geological survey and synthesis interpretation on seismic data, gravity anomaly date and aeromagnetic anomaly date of Lianyuan depression were used.
