CD 凸起北坡发育了东营组三角洲砂体,经过钻探证实具有较大的勘探潜力,但由于三角洲砂体储层横向上变化较大,单纯利用地震资料难以进行准确的油藏预测,尝试利用时频分析技术对三角洲砂体的沉积层序进行了划分,对三角洲砂体成藏条件进行了分析,为进一步的勘探开发提供了依据。

The CD arch developed in the north side of delta sand body in Dongying Formation , is identified to be have potential of petroleum exploration by drilling. As the obvious changes of the sand body in transversal ,the seismic data can’t be enough to forecast the reservoir. so the time-sequence analysis technique is tried to divide the sedimentary sequence of the sandbody , and analyze the forming conditions of sandbody , providing the evidence of exploration and development furtherly.
