F油田为中孔、高渗、高含水油田,其主力油层K层为三角洲沉积相体,储层顶部为一套砂质泥岩和不均匀分布的薄煤层.为了准确描述砂体及煤层的空间分布特征,为水平井眼轨迹设计提供准确的储层信息,利用地震属性反演.首先确定K层主要特征,在此基础上运用频谱成像技术进一步区分煤层和砂层.该研究在F油田成功完钻7口开发K层砂层顶部水平井钻井中起到了重要的参考价值,对于精细描述相似储层分布特征具有很好的参考意义.

F oilfield has middle porosity, high permeability and high water cut, the sedimentary facies of main production zone K belong to delta and at the top of the reservoir is a suit of sand-shale and un-uniformity distribution od thin coal bed. In order to describe the spatial distributing character of the main sand and coal correctly and provide more detailed information for horizontal well track design, seismic inversion study for K zone was conducted, based on this result, and then the spectral imaging technique was used to separate sand and coal in more detail. The study will be of important reference value in F oilfield horizontal well drilling atop the K zone sandstone and it will also provide help in similar reservoir fine distributing study.
