摘要
在一定地质条件下,利用亮点技术进行油气检测是一种有效可行的方法。理论证明,含油气之后岩石波速降低,从而引起地震反射波振幅相对增强(变化),因此利用地震资料上的亮点进行含油气预测,具有一定的可行性。在综合分析钻、测井和地震资料基础上,对含油气区域的地震资料进行研究,寻找亮、暗点与含油气关系,阐明亮、暗点形成的原因,并利用多种技术手段精细刻画亮、暗点,指出有利含油气区分布范围,为下步勘探指明方向。
In certain geological conditions,the use of bright spots technique for hydrocarbon detection is a kind of feasible and effective method.In theory,the wave velocity of rock which contains oil or gas will be reduced,leading to the enhancement（change） of seismic reflective wave amplitude.Based on the above theory,it is feasible that using the bright and dim spots technique on seismic section to forecast whether the rock contains oil or gas.Based on the analysis of drilling data,well logging and seismic data,the seismic data of region which contains oil and gas are learned,the relationship of bright and dim spots with oil and gas are looked for,the cause how the faded and dark spots form are illustrated,then several technical means are used to depict bright and dark spots carefully.Finally,the beneficial region which contains oil and gas and the next exploration direction can be pointed out.
