三维地震勘探技术在新疆山区的应用效果

Application Effect of 3D seismic Prospecting Technology in Xinjiang Mountainous Regions

新疆准南煤田铁列克井田地形复杂,冲沟发育,多为"V"字型谷,沟谷坡度较陡,区内最高处海拔2 121m,最低处为铁列克河海拔1 471m,高差650m。针对该地区三维地震勘探的主要难点,提出了针对性的技术措施,除了确保野外地震采集质量及室内资料保真等处理外,资料解释采用了全三维精细解释。实际勘探成果证明三维地震勘探技术在西部山区也可取得较好的勘探效果,为西部矿井高产高效提供可靠的地质信息。

The Tirek minefield of southern Junggar coalfield in Xinjiang has complex topography with developed gullies,mostly V typed valleys with rather steep gully slopes,highest altitude 2121m,lowest Tirek River altitude 1471m,altitude difference 650m.In allusion to main nodi in the 3D seismic prospecting in the area,pertinent technical measures have put forward.Except insuring of field seismic data acquisition quality and indoor data fidelity processing,the total 3D fine interpretation is used.Actual prospecting results have demonstrated that 3D seismic prospecting technology can obtain better prospecting effects in western mountainous regions,and provide reliable geological information for western coalmines＇ high yield and high efficiency production.
