桩海古潜山裂缝预测的方法研究—以胜利油田桩海地区为例

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。

Method study of fracture prediction in the Zhuanghai paleo-buried hill: an example from the Zhuanghai area of Shengli Oilfieid

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...
