基于广义等效介质激电模型的有限长源频率域一维正演
|
摘要
为研究广义等效介质激电模型(GEMTIP模型)中的极化参数对有限长导线源的频率域响应的影响规律,首先介绍了GEMTIP模型;然后将模型引入有限长导线源频率域测深一维正演中去;进而得到带激电信息的水平电场信号。重点研究了在层状介质条件下不同的极化参数对水平电场影响情况,通过分析发现体积占比对电场值的影响最大,在中高频处异常明显;其次是面积化系数,激电异常在低频处明显;相同极化参数对应的三层地电模型有如下规律:Q型模型的激电异常最大,反映极化层的能力最强,H型模型反映极化层的能力最差,A型和K型则位于两者之间。
In order to study the influence of polarization parameters on the frequency domain response of finite length source in generalized equivalent dielectric excitation model( GEMTIP model),the GEMTIP model first was introduced,then model was put into CSEM sounding 1 D forward,and get the information with electric field signal.The influence of different model parameters was studied on the horizontal electric field under the condition of layered media. The influence of the volume ratio on the electric field value is the most significant. The area coefficient is strongly reflected at the low frequency,and the polarization parameters are the same which at the three-layers geo-electric model has rules as follow. The Q type model has the largest excitation frequency,the strongest ability to reflect the polarization layer,the H type model reflects the polarization layer the worst,A type and K type is located between them.
