Description
技术领域technical field
本发明涉及一种地球物理勘探设备及方法，尤其是以二维或三维的测量方式同时实现核磁共振和瞬变电磁测量的地球物理勘探设备及方法。The invention relates to a geophysical prospecting device and method, in particular to a geophysical prospecting device and a method for simultaneously realizing nuclear magnetic resonance and transient electromagnetic measurement in a two-dimensional or three-dimensional measuring manner.
背景技术Background technique
核磁共振(MRS，MagneticResonanceSounding)探测方法是目前唯一的直接地下水探测方法，瞬变电磁方法通过探测地下介质的电阻率，也可以间接的实现对地下水资源的探测。Nuclear magnetic resonance (MRS, Magnetic Resonance Sounding) detection method is currently the only direct groundwater detection method, and transient electromagnetic method can also indirectly realize the detection of groundwater resources by detecting the resistivity of the underground medium.
目前，一维的核磁共振地下水探测仪器以及瞬变电磁仪器已经得到了广泛的应用，然而，在复杂地貌的条件下，一维核磁共振地下水探测仪器并不能很好的发挥作用，在与瞬变电磁仪器联用后，可增大对地下水分布的预测能力，二维或三维的探测，能更加准确的绘制出地下水体分布的二维图或者三维图，但是，目前并没有一台仪器能够通过二维或三维的测量方式实现核磁共振与瞬变电磁两种探测方法。At present, one-dimensional nuclear magnetic resonance groundwater detection instruments and transient electromagnetic instruments have been widely used. However, under the conditions of complex landforms, one-dimensional nuclear magnetic resonance groundwater detection instruments cannot play a good role. After the combination of electromagnetic instruments, the ability to predict the distribution of groundwater can be increased. Two-dimensional or three-dimensional detection can draw a two-dimensional or three-dimensional map of the distribution of groundwater bodies more accurately. However, there is currently no instrument that can pass Two-dimensional or three-dimensional measurement methods realize nuclear magnetic resonance and transient electromagnetic detection methods.
CN102096112公开的“基于阵列线圈的核磁共振地下水探测仪及野外探测方法”，用阵列线圈作为接收单元的天线，并为每个天线配置独立的接收单元，实现对地下水分布的二维或三维成图，从而提高了核磁共振找水方法在水平面上的探测精度。US7466128B2公开的“一种多通道核磁共振采集器和处理方法”，采用一个线圈发射多个线圈接收的测量方式，并通过自适应消噪方法，用多个通道的数据实现三维地下水密度的估计。以上两种方法，虽然能够实现二维或三维的核磁共振测量，但是，在复杂地貌条件下，单一的核磁共振方法并不能准确的对地下水体分布情况进行估计。CN102096112 discloses "Array coil-based nuclear magnetic resonance groundwater detector and field detection method", uses array coil as the antenna of the receiving unit, and configures an independent receiving unit for each antenna to realize two-dimensional or three-dimensional mapping of groundwater distribution , thereby improving the detection accuracy of the NMR water finding method on the horizontal plane. US7466128B2 discloses "a multi-channel nuclear magnetic resonance acquisition device and processing method", which adopts a measurement method in which one coil transmits and multiple coils receive, and uses the data of multiple channels to estimate the three-dimensional groundwater density through an adaptive denoising method. Although the above two methods can realize two-dimensional or three-dimensional nuclear magnetic resonance measurement, under complex landform conditions, a single nuclear magnetic resonance method cannot accurately estimate the distribution of groundwater bodies.
CN1936621公开的“核磁共振与瞬变电磁联用仪及其方法”，通过一台仪器实现核磁共振与瞬变电磁两种探测方法。首先，应用瞬变电磁技术找出地下低阻异常区，然后，应用核磁共振技术对低阻异常区进行探测，并将最终的核磁成像图与瞬变电磁成像图结合在一起，解释地下水资源的分布，通过这种方法能够有效的提高对地下水体的估计能力，但是，该方法并不能实现二维或三维的探测，这就导致了它的横向探测分辨率较低，在圈定井位时，存在着较大的打干井的风险。The "Nuclear Magnetic Resonance and Transient Electromagnetic Combined Instrument and Method" disclosed in CN1936621 realizes two detection methods of nuclear magnetic resonance and transient electromagnetic through one instrument. Firstly, the transient electromagnetic technology is used to find out the abnormal area of low resistance in the underground, and then the nuclear magnetic resonance technology is used to detect the abnormal area of low resistance, and the final nuclear magnetic imaging map is combined with the transient electromagnetic imaging map to explain the existence of groundwater resources. distribution, this method can effectively improve the ability to estimate the groundwater body, but this method cannot achieve two-dimensional or three-dimensional detection, which leads to its low lateral detection resolution. When delineating the well location, There is a greater risk of drilling dry wells.
