Title: Characteristics of Migration System of Paleogene Lingshui Formation in the Deep Water Area in Qiongdongnan Basin
Abstract: Coupled with Vail's classic stratigraphic sequence theory,comparison of seismic data in the deep water area with drilling data in the shallow water area divides the Paleogene Lingshui Formation of deep water area in Qiongdongnan Basin from bottom to top into four three-order sequences-SI,SII,SIII and SIV,and establishes a three-dimensional isochronous stratigraphic pattern in the target area.Based on the research above,this study defines the pathway system into reservoir,unconformity surface and faulting after systematic research on the migration system.Nine migration systems were summarized based on the migration elements and space configuration.Combined with the temperature and pressure data and fluid potential and hydrocarbon source rock of the basin,this study reveals that rift valley and half-rift valley are two important patterns of hydrocarbon accumulation and made the prediction for favorable exploration areas in the Lingshui Formation sequence on the basis of dominant migration system evaluation.
