摘要

扎赉诺尔煤业集团铁北矿勘探区目的层埋藏浅,地表条件复杂,成孔困难,很难到达激发层位,反射波能量及高频成分衰减大,对地震资料的信嗓比和分辨率降低。为此,经多次试验,在野外数据采集中采用合理的观测系统及相应的技术措施,资料处理和资料解释方法、流程得当,在勘探区钻孔资料少的情况下,保证了目的层速度场反演的准确性,取得了较好的地质效果。经矿井和生产实际验证,三维地震资料的精度较高。
In the Tiebei coalmine of Jalai Nur Coal Corporation, target coalbeds are shallow buried, surface condition is complex, because of drilling difficulties so boreholes are hardly to reach excitation horizons, fair-sized attenuation of reflecting wave energy and high-frequency component, all of these caused the lowering of signal to noise ratio and resolution of seismic data. Therefore, multiple tests were carried out; rational observing system and corresponding technical measures were introduced in field data acquisition, proper methodology and technological processes in data processing and interpretation, in the case of small amount of borehole data to ensure exactness in target layer velocity field conversion, thus, preferable geological interpretations were obtained. After mining verification, demonstrated the high accuracy of the 3D seismics.
