河南省濮阳县梨园岩盐矿区二维地震及矿层地质特征
|
摘要
河南省濮阳县梨园岩盐矿区位于东濮凹陷构造单元前梨园沉积中心。在区域矿产资源勘查的基础上,对区内岩盐矿资源进行普查评价。通过"二维地震先行、钻孔验证、数字测井、室内化验"等多重手段,基本查明了区内沙一盐的分布特征、埋深、厚度变化趋势。区内岩盐矿层具有连续多相位、强振幅、高视电阻率、低自然伽马等特征,垂向上呈盐岩—膏盐岩—泥岩的韵律层变化。岩盐资源量达到超大型规模的勘探成果表明二维地震勘探在岩盐勘探中的可行性,高信噪比的原始数据、资料的精细解释是获得丰富地质成果的基础。
The Liyuan rock salt mining area in Puyang County of Henan Province is located in the Qianliyuan deposition center of the tectonic unit of the Dongpu sag.Based on the exploration of regional mineral resources,the authors carried out a general survey of the rock salt resources in this area.Through the " two-dimensional earthquake first,borehole verification,digital logging,indoor laboratory" and other means,the distribution characteristics,depth and thickness of sand-salt in this area were basically ascertained.The rock salt deposits in the area have continuous multi-phase,strong amplitude,high apparent resistivity and low natural gamma.The vertical direction is the rhythmic layer change of salt rock-gypsum salt rock-mudstone.The exploration results of rock salt resources reaching a very large scale indicate the feasibility of two-dimensional seismic exploration in rock salt exploration.The high data-to-noise ratio raw data and fine interpretation of the data constitute the basis for obtaining rich geological results.
