To develop multi-purpose complex utilization and process kenaf seeds oil in depth , the application of kenaf seeds oil , to development of new healthy edible oil , enrichment of linoleic acid and synthesis of conjugated linoleic acid , is studied in the article .

Based on exploration achievements of lithological reservoirs in Erlian Basin,the hydrocarbon enrichment factors are analysed in four primary sags.

They have similar petroleum geological characteristics, but their hydrocarbon enrichment degree is apparently different.

Based on properties of Shenquan oilfield, as for plugging mode of main stress fault, plugging mode of lithologic fault, fault plugging of Shenquan oilfield is quantitatively analyzed, hydrocarbon accumulation regularity is studied, which provides a guideline for exploration and progressive development of Shenquan oilfield.

Along the large scale strike-slip faults,which are rich in hydrocarbon accumulation,many strike-slip basins develop.

The beach area of Shengli Oilfield is the preferred petroleum enrichment area of Jiyang Depression, and the reasons of hydrocarbon enrichment are various.
