宽方位角地震勘探与常规地震勘探对比研究
|
摘要
通过与常规地震勘探的对比研究认为,由于宽方位角勘探具有较大的纵横比、均匀的炮检距和方位角分布,因而纵横向能获得均等的地震波场信息和覆盖次数,突出了叠加各方向有效信息的能力。通过保真处理,可以最大可能地提炼有效信息。因此,在相同的解释技术条件下,具有更强的识别断裂和储层的能力,可以清晰地再现河道沉积特征,解决了岩性圈闭识别难度大的问题。较大地提高钻探成功率的能力必将使之成为未来岩性油气藏勘探的主要手段。
Through believed with the convention seismic survey contrast research,because the width azimuth exploration has the big aspect ratio,the even offset and azimuth distribution,vertically and horizontally to can obtain the equal earthquake wave field information and the cdp multilicity,has highlighted superimposition all quarters to effective information ability,through fidelity processing,may the most greatly possible refinement effective information,under the same explanation engineering factor,have the stronger recognition break and reservoir ability,may reappear the channel deposit characteristic clearly,has solved the lothological trap recognition difficulty big difficult problem,high enhances the drilling success ratio ability to will certainly to cause it to become the main method which the future lothological oil gas pool will explore.
