摘要
An analysis of provenance, paleocurrent,sandstone content isogram and distribution characteristics of sand bodies at Ek2 in Nanpi Sag has been conducted mainly based on 3D seismic data,combined with heavy minerals, sandstone content of single wells, seismic attributes and seismic facies interpretation. The results demonstrate that there are three main material source areas at Ek2 in Nanpi Sag: Xuhei salient, Dongguang salient, and Cangxian uplift. The two-direction paleocurrents with a portion of sediment from Xuhei salient and Dongguang salient had come together near well Wu 7, Wu 12 and Wushen 1, producing mix-deposition material source with the relatively high sandstone content.Nevertheless the sediment from Cangxian uplift definitely deposited in coastal shallow lake following the paleocurrent passed by well Ye 21 and Ye 22 in Nanpi Sag.
