开滦矿区采区三维地震勘探面积已达93.61 km2,通过探采对比获得了常规地震勘探成果资料的准确率为40.8%。通过应用三维地震数据动态解释系统进行预测预报,得到了三维地震数据成果动态应用的准确率为56.8%,准确率提高了16%。分析讨论了小型断层构造、薄煤带、岩浆岩侵入体等实例的三维地震曲线显示特征及其变化规律,可为三维地震勘探技术的应用提供指导。
The area of 3-D seismic exploration in the mining area of Kailuan Mine has reached 93.61 km2. The accuracy of the conventional seismic exploration results obtained through exploration and mining is 40.8%. Through the application of 3D seismic data interpretation system, the accuracy of the dynamic application of 3D seismic data is 56.8% and the accuracy is improved by 16%. This paper analyzes and discusses the 3D seismic curve display characteristics and variations of small fault structures, thin coal belts and magmatic intrusions, which can provide guidance for the application of 3D seismic exploration techniques.
