多种能源矿产的地球物理判识标志及其在协同勘探上的应用
|
摘要
石油、天然气、煤炭和砂岩型铀矿在同一盆地共同富集成藏为多种能源矿产的协同勘探提供了有利条件。地震和测井方法在各个能源矿产的勘探开发中都得到了广泛的应用。多种能源矿产的协同勘探应该利用现有的丰富的油气煤勘探开发资料(地震资料和测井资料)寻找砂岩型铀矿。鄂尔多斯盆地周边西缘逆冲带、天环凹陷、伊盟隆起和晋西挠折带这些砂岩型铀矿的远景区,据资料统计钻探油气井已达300口以上,为砂岩型铀矿勘探积累了丰富的地震和测井资料。
The fact that oil, natural gas, coals and sandstone uranium minerals exist in the same basin and form a mineral deposit provides favorable conditions for co-exploration of multiple energy minerals. The seismic and well logging methods have been widely used in exploration of various energy minerals. So co-exploration of multiple energy minerals is possible in terms of techniques and methods. Because the degree of exploration of oil, natural gas and coals is generally higher than that for sandstone uranium at present, we should use the available data (seismic and logging data) of exploration of oil, natural gas and coals to look for sandstone uranium deposits in co-exploration of multiple energy minerals in the basin. According to the statistics, more than 300 oil/gas wells have been drilled in the prospect areas of sandstone uranium deposits at the peripheries of the Ordos basin, such as the Tianhuan subbasin, thrust belts on the western edge of the basin, Yimeng uplift and western Shanxi flexural fold belt. These wells provide abundant seismic and logging data for exploration of sandstone uranium.
