摘要
The paleoprovenance system analysis is critical in terms of present sedimentary basin analysis, sequence stratigraphy study, and petroleum exploration practice. In this paper, the authors present a preliminarily summary of applying the “five-in-one” method to study provenace system of the Dongying Formation in the Qikou Depression. The so-called “five-in-one” method is a compositive analysis of light-heavy minerals, seismic progradational reflection structure features, paleogeomorphy and gully expansion features, skeleton sand body forms within the basin and the time-space expansion and matching rules analysis, and basin margin and the spatial expansion features analysis of large-scale incised valley developed in its internal sequence boundary. This method undoubtedly provides a reference for the researches of other basins within the same field. It will also further approach the real status of provenance system, and provide better service for petroleum exploration.
