Study On High Density Resistivity Physical Exploration Technology And Application

The paper comprehensively applies theories and method of geology prospecting and geophysical exploration, making use of Finite Element and magnitude analysis technology, study on field work technology and method of high density Resistivity,data of gathering and disposing,forward analysis, formation of Two-dimensional image and application; point at essence data processing, employ boundary element method to progressing topographic correction of resistivity sounding, and apply second order difference method to suggesting a high efficiency method of absorbing distortion point, through example test, it has good effect; based on the basic theories of two-dimensional Finite Element, completed two-dimensional Finite Element forward modeling program, establish foundation for more method inversion in the future; analyse 2-D least-squares inversion, combine four engineering example to study interpret technology of high density resistivity, sum up inversion regularity of some measure apparatus, supply theories scientific and consult experience for field work of high density resistivity.
