四川盆地TNB地区海相气藏构造精细解释与模型评价

Fine Interpretation and Model Evaluation of Marine Gas Reservoir Structure in TNB Area of Sichuan Basin

构造建模对于提高四川盆地TNB地区海相气藏评价精度具有十分重要的意义。而构造模型主要依靠已钻井资料和地震解释成果。基于此,文章在详细分析研究区构造特征并开展区域精细构造解释基础上,开展了基于井震结合的三维构造建模技术研究,以探索和形成规范化的基于井震结合的三维构造建模评价技术,为进一步深化海相气藏研究提供依据。

Structural modeling is of great significance to improve the evaluation accuracy of marine gas reservoirs in TNB area of Sichuan Basin. The structural model mainly depends on the drilling data and seismic interpretation results. Based on this, based on the detailed analysis of the structural characteristics of the study area and the regional fine structural interpretation, this paper carries out the research on the three-dimensional structural modeling technology based on the combination of well and earthquake, so as to explore and form a standardized three-dimensional structural modeling and evaluation technology based on the combination of well and earthquake,so as to provide a basis for further deepening the research of marine gas reservoirs.
