포항 지열 개발지역에서의 지열 저류층에 대한 SP 모델링
Abstract
Self-potential (SP) survey was carried out at Pohang geothermal field. SP measurement showed clear positive anomaly at northern part of the test wells, which can be a up-flow zone of the deep geothermal water due to electrokinetic potential generated by hydrothermal circulation. To give a clearer image of the fluid flow pattern around the test wells, a two-dimensional numerical simulation was applied to construct a numerical block model of the fluid flow system based on SP and magnetotelluric survey results. The result suggests existence of two high permeability zones including the main manifestation area in the northern part of the test wells.
