///Gentle slope in half graben basin presents the favorable conditions of oil and gas accumulation. Oil and gas accumulation in gentle slope is affected by several geological factors, namely oil source rock in gentle slope enriches the oil and gas abundance in high dip slope and controls the distribution of oil and gas in low dip slope. The dip of the strata in gentle slope controls the lateral migration distance and the scope of oil and gas distribution. Nose-shape structural zone is the target of oil and gas migration in gentle slope. The greater the displacement of the growth fault is, the more oil and gas layers are in gentle slope. The adverse faults showed a strong lateral sealing ability, controlling the distribution of oil and gas and forming the boundary of oil and gas accumulation in gentle slope.
