Abstract:
Based on the factual situations of Yanchang Formation in Longdong area, the rare earth elements, carbonate rock detritus, light and heavy mineral are analyzed. It is thought that there are mixed sources in the area. The directions of the provenance are mainly in the northeast and southwest. It is preliminary judged that the frontier of the northeast provenance probably lies in Nanliang-Huachi area and the frontier of the outhwest provenance probably lies in Yuele area. Finally, through the comparision of characteristics of three oilfield reservoirs, it is found that the provenance is an important factor for the formation of reservoir in Longdong area.
