Proni吸收滤波技术在文昌5区油气检测中的应用
|
摘要
应用Proni吸收滤波技术对文昌5区地震资料进行吸收滤波处理,通过对比及交会分析识别出吸收异常区,对区内主要目的层含油气性进行了预测。Proni吸收滤波技术克服了常规滤波技术和基于常规滤波技术的各种频率属性分析手段的局限性,使得可以通过不同主频和带宽的滤波结果来研究介质的不均一性。根据实际应用结果指出了应用Proni吸收滤波技术应该注意的问题。
The seismic data in Wenchang-5 area is processed by the technique of Proni absorption filtering,and some absorption anomaly zones are recognized by comparisons and crossplot analyses,on which hydrocarbon potential is predicted for the main target formations in the area.Avoiding limitations of conventional filtering and various frequency and attribute analyses based on this filtering,the technique of Proni absorption filtering can be used to research heterogeneity of medium by filtering results of various master frequency and bandwidth.Some problems that should be noted when applying the technique of Proni absorption filtering are listed according to its actual applications.
