引言 目前,人们开展的三维地震勘探研究工作,无论是用于勘探或者是开发,其目的是想在评价和钻探的过程中能够获得某些有助于降低风险的手段,包括能将含水储集层与油气储集层区分开来的方法。在盖层与储层间声阻抗差异较小的碎屑层序中,能够用于识别烃类的亮点并不存在,许多人错误地认为如果缺少亮点或直接烃类显示,将会使其在确定远景区或建议井位时不可靠性加大。有一种方法如能正确地实施,则不仅在亮点地区而且在无亮点(非亮点)地区
INTRODUCTION At present, the research on 3D seismic exploration carried out by people, whether for exploration or development, aims to obtain certain means of reducing risks during the evaluation and drilling, including the ability to store water-bearing reservoirs A method of distinguishing a layer from an oil and gas reservoir. Many of the bright spots that can be used to identify hydrocarbons do not exist in the detritus sequence where the difference in acoustic impedance between the cap and reservoir is small, and many mistakenly believe that the absence of bright spots or direct hydrocarbon display will make Increased unreliability in determining prospects or proposed wells. If a method is implemented correctly, it is not only in bright spots but also in bright spots (non-bright spots)
