| 摘 要： | 简要介绍了应用分形技术和地震模式识别技术进行油气预测的方法原理。以江苏金湖凹陷西１断块为例，计算了地震道的分维（关联维和振幅谱维），发现油层与非油层的分维是不相同的，分维可以作为油气预测的一个重要参数。为了克服地震资料信噪比和分辨率的限制，还利用地震模式识别技术进行了油气预测．

| Abstract: | The priciples of fractal and seismic pattern recognization for oil and gas prediction are discussed. Taking Jinghu depression Xi - 1 block, Jangsu province, as an example, the fractal dimensions of seismic data are calculated within the target horizon. This fractal dimension for oil - bearing strata is different from no oil - bearing strata. So it can be used as an important parameter for oil and gas prediction. To overcome limit of seismic data S/N and resolution, oil and gas is also predicted by seismic pattern recognition. |
