| 摘 要： | 利用倾斜线状电流源的理论电位式和有限差分法理论,建立三维离散化方程组,并用ICCG法求解该方程组,设计三维电阻率异常体分布模型,经计算得到了地表视电阻率分布在垂直和倾斜线源情况下的变化规律。以上工作对利用直流电法勘探方法,来解决油田剩余油的分布及对地浸砂岩型铀矿矿层渗透性能的分析,有着实际的意义。

| Abstract: | In the paper,by utilizing the geoelectric field theory of inclined line source and finite-difference method,a 3-D discrete equation has been set up according to anomalous potential satisfied by current exploration,and quickly solved with ICCG method.Some models with resistivity anomalous distribution are designed and the distribution regularity of apparent resistivity varied with anomalous body under vertical and inclined situation are obtained by calculating models.All these works have practicality signification for solving the distribution of oil field residual oil and analyzing the pervasion capability of uranic sandstone by using direct current exploration. |
