摘要
烃类检测是早期油藏描述的重要任务之一,根据对我国东部几个含油气构造实际资料研究,提出了如下三种方法:1.应用亮点原理确定烃类的地震模式及其在纵向上的分布特征;2.应用AVO技术,进一步确定地震储层和垂向分布特征以及划分油气边界;3.在以上研究基础上,我们提出了一种利用多种地震参数进行烃类综合检测的方法及实现过程。文中给出了一些实例来说明方法的使用效果。在不断的完善和充实之后,这些方法会在油气勘探过程中得到广泛的应用。
Hydrocarbon detection is one of the important tasks in the earlier-stage reser-voir description.According to the actual data about several hydrocarbon-bearingstructures in eastern China, the authors have presented three methods as follows:(1) to determine the seismic models and its vertical distribution in the hydro-carbon-bearing formations by applying the principle qf bright spot;(2)to deter-mine further the seismic responses and its latteral changes and outline the reser-voir edges, which are obtained by AVO method;(3) on the basis of the above-mentioned studies, to use a new scheme called in tegrated hydrocarbon detectionand the process to realize this purpose. This method calls for the application ofa large amount of multi-seismic parameters. Finally, some examples has been illus-trated with a view to showing their using effects. These methods will be widelyused in the process of oil and gas explofration after being perfected and substan-tiated.
