【摘要】 针对研究区滩坝砂体薄互层、横向变化快、分布复杂的地质特点,基于相似背景的分离技术能够在地震资料上突出更多的薄层反射特征,为此,本文基于该技术优势,建立了滩坝砂体相似背景分离技术实现方法与处理流程。该技术应用于济阳坳陷东营凹陷沙四段的储层预测的结果表明,该技术能够提高地震资料的分辨率,揭示出更多的薄层地震响应,更准确地反映了主要目标层段的储层横向变化细节,有效地指导了研究区油气勘探实践。更多还原

【Abstract】 The beach-bar sandbodies of the Es4 in Dongying area are of the complex geologic characters of thin sand-in-mud layer and lateral variation large,complex distribution.Separation technology based on seismic semblance background can reveal more reflecting features of thin layers on seismic profile.A scheme of separation technology of semblance background has been built and applied to the reservoir prediction of beach-bar sandbodies of the Es4 in Dongying area.The results show that the seismic data resolution is raised,the more features of thin layers in seismic profile are revealed.This technology can display accurately the reservoir lateral variation in detail on the main target layers and instruct effectively oil and gas exploration in the area.更多还原
