高精度三维地震资料解释技术在查干凹陷的应用

Application of High-Accuracy 3D Seismic Data Interpretation Technique to Zhagan Sag

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 high-accuracy 3D seismic data coverage in Zhagan sag as an example,starting with seismic fine calibration,the means like coherent strata slices,variable velocity diagram,balanced profile and lithology trap prediction are applied to well solving the distribution of complex structure and fault system and the description of reservoirs in this area,the obvious explorative effectiveness has been achieved,which are valuable to other similar areas in geology.
