Seismic Interpretation of Special Lithologic Body and Evaluation of Lithologic Traps-Taking the Target of the Lower Jurassic in the Western Region of Block K of the South Turgay Basin as an Example

摘要

Based on a detailed analysis of the geologic conditions of the Jurassic,this study carries out fine interpretation of tectonic pattern of the research area and several lithologic traps through the finely constructed 3D seismic data,and conducts an evaluation in detail with the lithologic strati-graphic traps of the Lower Jurassic after optimization.According to the study of structure,reservoir prediction research and hydrocarbon accumulation analysis,the results show that the target is of superior oil source conditions,good reservoir physical property,superior reservoir conditions,and the reservoir anomalies are obvious.It is thus a favorable self-generated and self-storage type exploration target in the deep layers of the Aryskum sag.
