精细地震层序地层分析技术及应用——以渤海湾盆地歧口凹陷滨海地区为例
High-precision analysis technology of seismic sequence strata and its application:A case study of Binhai region in Qikou Sag, Bohai Bay Basin
摘要
Abstract
Common technology of seismic interpretation on sequence strata has much limitation. For example, the space distribution and imbricate pattern of sedimentary units within system tract can not be interpreted. Also, strictly speaking, it is hard to establish isochronous stratigraphic sequence framework. The strata slices which are of isochronous meaning are difficult to achieve. In order to resolve these problems, this paper adopts a new seismic interpretation technology of sequence strata to identificate the boundary of sequence and system tract, and to calibrate and demonstrate the variation of deposition cycle displayed in Wheeler domain, and to clarify the distribution law of sand, and finally to identify lithologic trap. This paper confirms the maximum flooding surface, first flooding surface and sequence boundary by the technology in Binhai region of the Qikou Sag, and progresses constrained seismic inversion, and finds many lithologic traps in LST. The practical application of this technology has been proved feasible and efficient.关键词
