| 摘 要： | 波动方程叠前深度偏移技术是复杂地表地震资料成像的有效方法。应用炮域波动方程傅氏有限差分法对江汉平原深层海相和鄂西渝东地表复杂地区地震勘探资料进行叠前深度偏移处理,与常规时间偏移剖面相比,所反映的构造特征清楚,断层位置清晰,为江汉油区油气勘探提供了可靠的地质依据。

| Abstract: | Wave equation prestack depth migration technique is an effective method of seismic data imaginating in complicated surfaces. We have used the shot field wave equation about Fourier finite-difference (FFD)method for processing some seismic exploration data in deep marine of Jianghan plain and in the complicated surface region of western Hubei and eastern Chongqing . Comparing with general time migration profile,it has reflected structural feature more clear,and fault location more obvious. It has provided reliable geologic bases for oil and gas exploration in Jianghan Oil Region. |
