改进的角度边界识别方法及其在延吉盆地的应用
|
摘要
通过几何分析证明常用的tilt梯度和theta图边界识别方法在原理上是相通的,并利用几何意义将其统一成角度边界识别方法,同时给出其他的角度边界识别方法计算公式.在此基础上,为了提高传统角度边界识别方法的精度以及改善其对细节构造探测能力的不足,提出了新的基于标准差计算的角度边界识别方法:先对异常3个方向导数做窗口内标准差计算,然后求取角的反正弦、反余弦及反正切等反三角函数.该方法计算简单、易操作.通过模型实验对比,发现改进后的方法能识别细节构造,检测到更多异常信息,证明了改进方法的优越性.将改进后的方法应用于延吉盆地,不仅确认了地质资料中已有的12条断裂,且探明了与地震资料相吻合的3条新断裂,这将为进一步为研究延吉盆地提供地球物理依据,并对延吉盆地油气远景预测提供新的参考.
In this study,we firstly prove by geometry analysis that the edge detection method of tilt angle and theta map share the same theoretical framework,then we uniform them as angle edge detection method.In order to improve the precision and the detectability of details,the angle edge detection method is established based on a standard deviation calculation involving the following two steps.Step 1is calculation of standard deviation of the three directional derivatives within windows,while Step 2 is calculation of the trigonometric function of inverse sine,cosine angle and arc tangent.The new method is simple and easy to operate.The model tests demonstrate that the improved method can identify the details and detect more anomaly information. The improved methods were applied to Yanji Basin,which not only confirms 12faults that are already available in the geological information but also finds three larger fractures accordant with the seismic data.The research results provide new geophysical information for the further study of Yanji Basin.
