深层浊积砂砾岩体地球物理预测技术研究
|
摘要
导致深层勘探与开发程度低的因素很多,其中储层问题是主要技术瓶颈,对深部储层开展多种地球物理技术研究,准确描述储层空间展布特征是急需解决的问题。针对深部储层预测的难题,以车镇凹陷深水浊积扇为例,建立了一套以储层段岩性组合为出发点,确定其优势地震响应,并根据优势地震响应进行储层预测的综合分析方法和技术流程,并在油气勘探实践中取得了良好的应用效果,探索出了一套深层砂砾岩体储层预测的技术方法。
Many factors result in low degree of exploration and development of deep formation.Reservoir is the main technical bottleneck.So a variety of geophysical researches should be carried out to describe the spatial distribution characteristics of reservoir accurately.Aiming at the problems of prediction in deep reservoir,comprehensive analysis methods and technological processes are established by taking deep-water turbidite fans of Chezhen Sag as an example,in which,lithologic association of reservoir is taken as a starting point to determine the dominant seismic response and reservoir prediction make based on it.The analysis methods and technical processes bring a good result in oil and gas exploration,and a set of effective technical methods are explored in prediction of deep buried glutenite.
