It is believed that the Yingshan sag,a kind of large-scale deep sag under the control of transtensional faults,is another target for deep gas exploration following the Xujiaweizi depression.

The petrophysics study on deep andesite rocks is very important in Yingshan downcast of Songliao Basin, because gas reservoirs have been discovered in the area of deep andesite.

Reservoir controlling mechanism and petroleum accumulation model for consequent fault and antithetic fault in Fushan Depression of Hainan area;

A discussion on the Palaeogene sublacustrine fan of Fushan depression in Beibuwan basin, northern South China Sea;

By using(δ~(13)C_2-δ~(13)C_3) versus C_2/C_3(mol/mol) plot and "natural gas plot",and the ternary diagram of C_7-hydrocarbon of natural gas,this paper studies the genesis and source of the natural gas discovered in the Fushan depression,Hainan.

The geotectonic position of study area lies in the southern margins of the Zhungeer depression and Dalongkou depression, which belong to the Urumchi piedmont depression.
