不同勘探开发阶段的储层地震描述技术

Seismic Description Technology of Reservoir Characteristics in the Progress of Exploration and Development

油田勘探开发的程序采用"滚动"方式进行,而对储层特征的研究则逐步精细化,滚动勘探开发的效果取决于对油气藏的认识程度,而在预探发现工业油流后,构成油气藏多元素之一的储层特征研究则是保证油气藏持续稳产的基础。不同的"滚动"阶段应根据储层的复杂性和认识程度采用不同的技术方法。本文主要针对油田滚动勘探开发过程中储层研究的特点,从正演模型出发,对地震参数与储层特征的对应关系及地震描述技术的有效性进行剖析,总结了不同勘探开发阶段储层特征地震描述技术系列,在实际应用中取得了较好的效果。

The 'progressive' method is applied as the process of oilfield exploration and development, with its effect dependent on the degree of understanding of oil & gas reservoirs. Study on reservoir characteristics, a constituent part of oil & gas reservoirs and was deepened step by step, is the basis for guaranteeing persistent stable production of oil & gas reservoirs. This paper starts with forward model according to the reservoir study characteristics in the process of progressive exploration and development, and analysis the correlation between seismic parameter and reservoir characteristics and the effectiveness of seismic description technology. It suggests that different geologic topic corresponds to different seismic parameters and technologies. If valid seismic parameters and description of reservoir characteristic are chosen based on detailed geologic analysis, true features of reservoir and hydrocarbon in different period of exploration can be known well so as to improve the effect in exploration and development.
