摘要:
提要:利用地震、测井、岩心等资料,对该区进行层序地层学的分析和研究, 在层序地层单元划分和对比的基础上,将饶阳凹陷古近系沙河街组划分出6个三级层序,并对每个层序的主控成因进行了详细的研究,总结出各层序的不同特点。同时对每个层序内部的沉积特点和沉积体系进行了分析,指出了层序发育对沉积体系的控制作用。研究过程中,还对层序不同体系域的油气藏类型和油气聚集规律进行了研究,并指出了各体系域可能发育的最有利的油气藏类型。

Abstract:
Abstract:The sequence stratigraphy and sedimentary system of the Paleogene Shahejie Formation of the Raoyang subbasin have been studied by employing seismic, well log and drilling core data. On the basis of the identification and correlation of sequence stratigraphic units, the Shahejie Formation has been divided into six third-order sequences and 14 system tracts. The paper analyzes the main cause of formation of each sequence in detail and sums up different characteristics of various sequences. In addition, the sedimentary characteristics and sedimentary systems in each sequence are analyzed and the controlling effects of sequence development on the sedimentary systems are pointed out. During the study, the authors also studied the types of oil-gas reservoirs and characteristics of oil-gas accumulation in different system tracts of a sequence, and on that basis, they indicate the most favorable oil-gas reservoir types possibly developed in various system tracts.
