bearing series

and a good intraplot source-reservoir-cap assemblage and widely spread oil-bearing series are formed.

Laohekou oil field is located at the north slope of Chengdong arch, and the upper Guantao Formation is the main oil-bearing series.

Finally, the tunnel support strategy with the features of coal-bearing series at Longkou Mine was proposed.

Four new spindle bearing series from FAG increase the productivity of machine tools.

The forth segment of Shahejie formation(ES_4) is a new oil-bearing series found in the east slope of Niuzhuang Sag since 2004.
