裂缝密度 meaning in Chinese
fracture density
Examples
- When tiie density of fractures is great , the effect of multi - fractures is similar to the single fracture with the thicknesses equating to the total thickness of multi - fractu
当裂缝密度较大时，多条裂缝的影响相当于厚度相同单条裂缝的影响；当裂缝密度较小时，多条裂缝的影响可以分辨出来。 - Pirected by the theory of regression analysis , we get the seismic arribute data by the moden specturm estimation and predict the fractured density by the wavelet multiple - scale regression analysis
同时在回归分析思想指导下，通过现代谱估计提取地震属性参数，将小波多尺度回归法用于裂缝密度预测。 - But the change of reflection coefficient is three times as much as the change of velesity resulted from fractured density , which shows that dynamical characteristic of seismic wave is more sensitive to fracture than kinetic characteristic
而对于同级别的裂缝密度，反射系数的变化量是其速度变化量的3倍左右。揭示了地震波的动力学特征比其运动学特征对裂隙更敏感。 - Simultatly , based on the vaviaction of seismic signal - noise ratio , the anthor use the funtion singular method in the seismic data procesy and put forward the wavelet amplitude singular exponentid method and the wavelet power spectrum singular exponential for the fractued density detection
与此同时，将函数奇异性分析的思想引到地震信号处理中来，针对地震信号信噪比的高低，提出小波振幅奇异性指数法和小波功率谱奇异性指数法的裂缝密度检测方法。 - Therefore the dynamical characteristic is acted as detected parameter for fractured detection ( primary amplitude secondary frequence ) . and the amplitude of mean sguare and central frequence are acted as evaluational parameter , based on the those studies , the new ideas is put forward that fractured azimuth is dected by lateral difference and fractured density is dected by vertical difference for three facters of fracture , wavelet acted as analysis tool and direction by wave field characteristic applied the multiple scale edge dectection and self - adaptive edge detection into the detection theory of seismic fractured azimuth , also put forward the wavelet different scale filter method of the fractured azimuth detection
因而，确定了主要以振幅，其次是频率的地震波动力学特征作为裂缝检测的被检参数和均方振幅和中心频率作为检验检测结果正确与否的评价参数。在上述研究基础上，针对裂缝的三要素，提出通过横向求异检测裂缝方位和纵向求异检测裂缝密度的新思想。并以小波作为分析工具，以潜山波场特征作指导，将数字图像处理中的多尺度边缘检测和自适性边缘检测引用到地震裂缝方位检测中来，并提出了小波变尺度滤波法新的裂缝方位检测法。
