摘要

裂缝性油气藏的产量占世界石油天然气总产量比重较大

对裂缝性油气藏的研究已成为当今世界石油界的热点。由于裂缝分布复杂

其识别工作便成为研究中难题。从胜利油田桩海区块的古潜山裂缝的实际资料出发

利用小波分频处理和小波多尺度边缘检测等方法

对地震记录进行处理

一方面不仅改善了地震资料的品质

另一方面又压制噪音

突出了有效波

有利于进一步研究构造与储层特征

并达到预测裂缝最优的目的。

Abstract

Output from fractured reservoirs takes up a big chunk in world's total oil and gas production.Study of fractured reservoirs has become a focus of the industry.However

due to a complicated distribution of fractures

the identification of the fractures has been a headache for researchers.Based upon the real data of fractures in paleo-buried hill of the Zhuanghai area

Shengli oilfield

we processed seismic data by employing wavelet fre-quency division processing method and multiscale edge detection.As a result

effective waves are highlighted as the quality of seismic data is improved and the noise is eliminated.This is favorable for the further research of reservoirs in structural domain and optimization of fracture prediction.
