Controllable source electromagnetic wave resistivity static sounding CO2 in-situ monitoring method and device
The invention discloses a controllable source electromagnetic wave resistivity static sounding CO2 in-situ monitoring method and device, and the method comprises the steps: arranging a transmitting coil and two receiving coils on a static sounding probe, and enabling the two receiving coils to be different from the transmitting coil in height; an electromagnetic wave with a certain frequency is transmitted to a stratum through a transmitting coil, and the electromagnetic wave from the stratum is received through two receiving coils, and the electromagnetic wave contains stratum dielectric information; determining the induced electromotive force of the electromagnetic waves from the stratum received by the two receiving coils; the phase difference and the amplitude ratio are determined, then the resistivity and the dielectric constant of the stratum are obtained according to the function relation between the phase difference and the amplitude ratio and the resistivity and the dielectric constant of the stratum, and CO2 in-situ monitoring is achieved. According to the invention, resistivity and dielectric abnormity caused by CO2 injection are monitored through single-transmitting and double-receiving electromagnetic waves, so that the purposes of timely mastering the CO2 migration range and the leakage condition and adopting emergency response in advance are achieved.
本发明公开了一种可控源电磁波电阻率静力触探CO2原位监测方法及装置，该方法包括：静力触探探头上设置一个发射线圈和两个接收线圈，两个接收线圈距离发射线圈的高度不同；通过发射线圈向地层发射一定频率的电磁波，并通过两个接收线圈接收来自地层的电磁波，其含有地层介电信息；确定两个接收线圈所接收的来自地层的电磁波的感应电动势；确定其相位差和幅度比，再根据相位差和幅度比与地层的电阻率和介电常数之间存在的函数关系，得到地层的电阻率和介电常数，实现CO2原位监测。本发明通过单发双收电磁波监测CO2注入引起的电阻率以及介电异常，从而达到及时掌握CO2运移范围以及泄漏情况并提前采取应急响应的目的。
