| Synthetic Application of the Provenance Analysis Technique : A Case study of Member 1 of Taizhou Formation in Gaoyou Sag, Subei Basin |
| At present, the lithologic hydrocarbon reservoir is the target in exploration activity along the Gaoyou sag deep zone, and the lithosome reservoir is critical in detecting the hydrocarbon reservoir. The determination of the provenance is the key to the exact prediction of litosome. The authors analyzed the provenance of Gaoyou sag by using the methods of heavy minerals, clastic constituents and sedimentation. Heavy mineral correlation and R cluster analysis indicate that there exist two main provenances originating respectively from the south and from the north of Gaoyou sag. The method of clastic constituents shows that the provenance originated from multiple deformation of the recycled orogen zone. The method of sedimentation suggests that, besides the two main provenances, there is also a secondary provenance. The three provenances originated from Tongyang uplift, Jianhu uplift and Lingtang low bulge, respectively. The contribution of the provenances to Gaoyou sag decreases progressively in order of the above uplift sequence. |
