摘要
研究了地震数据结构特征与含油气性的关系,从而可在地震剖面上定量解释油气层,进而对探井,评价井等进行钻前油气预测,15个构造19口井的钻前油气预测结果表明,预测准确率可达80%以上,取得了显著的经济效益,本文适用范围:岩石类型为陆源碎屑岩,沉积环境为海相,海陆过渡相(三角洲相)和陆相(河流相,湖泊相),深度范围为800-5000m,预测岩层厚度为10m以上(主频50Hz左右)。
This paper has discussed a relationship between numerical structure of seismic data and hydrocarbon prediction, by which it is possible to explain quantitatively oil bearing layers in seismic profile and to make predrilling prediction of hydrocarbon. Actual prediction results from 19 wells and 15 structures show that its success ratio may be over 80 percent, resulting in a significant economic effect. The scope of application for this technique are:non marine clastic rocks, marine, delta and non marine facies(fluvial and lacustrine facies), burial depth ranging from 800 to 5000 meters, detected layers thick over 10 meters(main frequency about 50 Hz).
