利用场源边缘检测方法研究北黄海某盆地火成岩分布特征
|
摘要
本文通过模型试验,对水平梯度、解析信号模水平梯度、斜导数及其水平梯度、θ图法及其水平梯度、归一化均方差等场源边缘检测方法的应用效果开展研究,并将这些方法应用于北黄海某盆地火成岩分布特征研究.模型试验和实际应用研究表明,没有一种方法是永远有效,综合运用多种方法进行场源边缘检测,压制干扰,识别出有效的边缘特征.对比地震识别的结果,场源边缘检测方法所识别出的北黄海某盆地的火成岩分布范围更加全面、准确,对后期的油气勘探工作意义重大.
By the synthetic model,we have contrasted the effects of the main methods of edge detecting,such as total horizontal derivative(THDR),total horizontal derivative of analytical signal amplitude(AS_THDR),tilt angle and its total horizontal derivative(TA,TA_THDR),θmap and its total horizontal derivative(θmap,θ_THDR),normalized standard deviation(NSTD).Based on the synthetic model,we predict the igneous rocks distribution of one basin in North Yellow Sea using these edge detecting methods.The result of the synthetic model and the application in one basin of North Yellow Sea,suggest that it is the best way to suppress noises and detect useful edges by compressively using these methods and there is no best method alone for good.Comparing to the result of edge detecting of igneous rocks by seismic,the results detected by the edge detecting of the potential field are more comprehensive and more accurate,which make sense for upper exploration work of gas and oil.
