开滦矿区三维地震技术应用效果及实例分析

Application Effects and Case Analysis of 3D Seismic Technology in Kailuan Mining Area

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 detected mining area has reached 93.61 km2 where the 3D seismic technology is applied in Kailuan mining area, and through the comparison study between exploration and exploitation, obtain the regular 3D seismic exploration results at the accuracy of 40.8%. Forecasting by the 3D seismic data dynamic interpretation system, get the accuracy at 56.8% on the dynamic application of the 3D seismic data, which is increased by 16%. Analyze and discuss the characters and variation of different geological factors displayed on the 3D seismic exploration curves by the examples of the small fault structure,thin coal belt and magmatic rock intrusion. The research can provide practical guidance for the 3D exploration technology.
