Abstract：Based on the comparison of play source rock and hydrocarbon phase,hydrocarbon pooling characteristic and difference in the south fault belt from west to east have been summarized,and tectonic movement difference was thought to be the main controlling factor causing difference of hydrocarbon pooling characteristic in south fault belt,West Pearl River Mouth Basin.Three kinds of multihydrocarbon pooling patterns have been put forward by the differences of structural style and valid source-hydrocarbon:the first pooling pattern is "two periods of tectonic inversion—Wenchang source rock-derived" developed in the west segment of the south fault belt.Hydrocarbon generating,pooling and distribution are controlled by early Oligocene Enping period and mid-Miocene Hanjiang period tectonic inversion movements.Hydrocarbon derived from Eocene Wenchang Formation was characterized by multi-pooling.The second pooling pattern "late tectonic inversion—Enping source rock" existed in the middle segment of the south fault belt,hydrocarbon generating,pooling and distribution are controlled by lateral extension difference,tectonic subsidence difference and Mid-Miocene Hanjiang period tectonic inversion movement,hydrocarbon derived only from Lower Oligocene Enping Formation,characterized by multi-period pooling and vertically well-superpositioned pooling.The pooling third pattern is the "continuous extension—Wenchang and Enping dual source rock" existed in the east segment of south fault.Hydrocarbon generating,pooling and distribution are controlled by growth fault movement and tectonic subsidence shift towards east,and hydrocarbon derived from both Wenchang Formation and Enping Formation,characterized by multi-source and multi-period pooling.
