以查干凹陷高精度三维资料覆盖区为例,从地震精细标定入手,以高精度三维地震资料精细构造解释为主,综合应用相干体地层切片、变速成图、平衡剖面、岩性圈闭预测等技术手段,较清楚地认识了该区复杂构造断裂系统分布和解决了储集层描述中存在的问题,取得了明显的勘探效果,这对其他类似地质条件的地区具有一定的参考价值。
Taking the high-precision three-dimensional data coverage area of Chagan Sag as an example, starting from the precise calibration of seismic data, the detailed structural interpretation of high-resolution 3D seismic data is the main method. The coherent stratum slice, velocity mapping, balance profile, lithologic trap prediction And other technical means, we can clearly understand the distribution of complex structural faults in this area and solve the problems existing in reservoir description, and have obtained obvious exploration results, which is of certain reference value to other areas with similar geological conditions.
