摘要
The shallow reservoirs in Qikou Sag are mainly typical complex fault blocks,which are characterized by hydrocarbon enrichment and high productivity.The developments of shallow fault block structures are controlled by the rift system consisted of diagonal faults.The hydrocarbon accumulation scale in the shallow layers is determined by the major faults and channel sand body.The geotectonic movement is helpful to hydrocarbon accumulation in the ultra-shallow layers.
