地震反演成果的沉积学解释
|
摘要
在油气藏勘探和开发中,沉积特征的研究具有重要意义,而将地震反演技术与沉积学原理结合进行沉积特征的刻画,是目前利用地震资料开展沉积微相研究最有效的方法。为了使反演结果贴近地下地质特征,将地震相控概念引入非线性随机反演中,在CZ凹陷C15井区进行探索性应用,以地震沉积学理论为指导,结合地震相分析,基于高精度地震反演成果进行了沉积特征解释,比直接在地震剖面上进行沉积描述具有更高的可靠性,获得了比较精细的沉积微相描述。
Research of sedimentary characteristics is very important in the process of reservoir exploration and development.Seismic inversion technology is combined with sedimentological principle to characterize sedimentary features,which is the most effective method to carry on sedimentary microfacies research based on seismic data.Seismic phase-controlled concept is brought into nonlinear random inversion to make inversion results approach geological features.Guided by seismic sedimentology theory,combined with seismic facies analysis technique,based on high-accuracy seismic inversion results,sedimentary features are interpreted in well area C15 of CZ depression as a exploratory application,which has higher reliability than sedimentary features characterized directly on seismic section and yields better fine sedimentary microfacies characterization.
