激电三极测深在寻找陡立含水破碎带中的应用
|
摘要
电阻率测深法装置多,对称四级测深法是经典、常用的。但在工作区场地不具备四极跑极的条件下,开展三极测深也很普遍。为了在勘查区寻找地下水源,利用激电三极测深装置对其进行视电阻率和视极化率测量,并对测量结果进行分析。通过实际勘查工作资料的数据反演和物理模拟得出,对激电三极测深获得的陡立低阻、高极化异常带,钻孔不应定在异常中心部位,而应定在低阻、高极化梯度带上。钻探结果表明,在110m左右打到了陡立含水破碎带,在含水的贫困地区找到了丰富的地下水源。
The method of resistivity sounding has many devices,and the method of symmetrical fourpole sounding is the classical and popular.However,under the condition of not having four-poles running in the working area,it is also very common to carry out three-sounding.In order to search underground water sources in the exploration area,the apparent resistivity and apparent polarization are measured by using apolarization sounding device,and the measurement results are analyzed.Through data inversion and physical simulation of the actual exploration,the vertical low resistance and high polarization anomaly zones obtained by the IP sounding are difficult for the drilling hole to fix at the abnormal center,but it should be fixed on the low resistance and high polarization gradient zone.Drilling results show that the vertical water-bearing fractured zone is drilled in about 110 meters and the abundant underground water source is found in the poor areas of containing water.
