方差体技术是检测地下断层及地层不连续变化现象的卓有成效的一种技术。文章介绍勘探区的概况和三维地震的数据采集、资料处理和解释,并阐述了方差体技术的原理。通过该技术在新桥井田的实际应用,显示了方差体技术对三维地震地质信息自动拾取以及有效地提高地震资料解释成果精度等方面的良好效果。 Variance body technique is an effective technique to detect the discontinuous variation of underground faults and formations. The paper introduces the general situation of exploration area and data acquisition, data processing and interpretation of 3D seismic data, and expounds the principle of variance body technology. The practical application of this technology in the Xinqiao well field shows the good effect of the variance body technology in automatically picking up 3D seismic geological information and effectively improving the accuracy of the seismic data interpretation results.
