Abstract:

To solve the quantitative characterization whether structural traps contain oil

or how much they contain in west Sag of Liaohe Depression，133 structural traps are researched on the basis of statistical geologic analysis and R-factor analysis，the results show that the distances between the center of hydrocarbon expulsion and trap，the fluid potential energy，the depth of caprock，the depth of sand bodies and the numbers of the faults cutting the reservoirs are the controlling factors influencing the fullness degree of structural trap.The comprehensive quantitative prediction models between the fullness degree and the controlling factors of structural traps are established.They are examined through selecting 16 structural traps.The validation results of the forecasting models indicate that the value of 85% forecasted fullness degree of the trap is consistent of the factual value，implying that the forecasting method can be used in oil prospection.

Key words: structural trap, oil-bearing, main controlling factors, quantitative model, West
