Petroleum Resource Potential and Advantageous Exploration Targets in Ying-|Qiong Basin, Northern Margin of South China Sea
Online published: 2008-04-20
Many natural gas fields and oil\|bearing structures in the Ying\|Qiong basin have been discovered since 1960s. They are chiefly located in the shallow strata of mudsone diapir zones of the Yinggehai basin and in the Ya'nan sag of the Qiongdongnan basin, and have a total gas resource amount more than 0.1 billion cube meters. However, the total exploration degree in this area is very low and the advantageous exploration targets are ambiguous so that the status of petroleum exploration is very passive, without any obvious breakthrough. On the basis of previous petroleum geological laws, therefore, we analyze petroleum resource potential and advantageous exploration targets in different areas of the Ying\|Qiong basin according to their migration and accumulation characteristics. As a result, new exploration areas and possible\|breakthrough targets are pointed out. Furthermore, the middle\|deep beds of the Yinggehai basin and southern deep\|water slope of the Qiongdongnan basin are considered to be the best new exploration targets with excellent resource potential and may become a breakthrough. But now research about these areas is so weak that we should focus our best efforts on the petroleum exploration.
