本文以地震地层学的理论为基础，以双断式箕状盆地陡坡区、斜坡区及湖心区沉积的三分性为背景，建立了TBC地震层序，分区确立了地震相的特点，结合古地理环境、古水流方向及物源区的探讨，辅以钻井岩性、电性的分析、测并相的分析以及构造沉积相关系的探讨，确立了地震相的沉积相解释及沉积相的平面分布，在此基础上确立了有利的储集相带。 Based on the theory of seismic stratigraphy and the trichotheticity of the sediments in the steep slopes, slopes and central lake areas of the double-broken, half-graben-type basin, the TBC seismic sequence was established and the characteristics of the seismic facies were established. Paleogeography, paleocurrent flow direction and provenance area, together with drilling lithology, electrical analysis, the analysis of the measured phase and the relationship between tectonic and sedimentary facies, the sedimentary facies facies interpretation and sedimentary facies Plane distribution, on the basis of which established a favorable reservoir facies belt.
