The Underground Water Quality Evaluation from Electrical Logging Data in Sandstone District: A Case Study in Daqing Oil Field

Abstract:

As an important yardstick of water quality evaluation, total dissolved solids (TDS) is strongly correlated with apparent resistivity and static spontaneous potential (SSP) parameters from electrical logging curves.A lot of electrical logging data accumated in the hydrogeologic survey during last decades can be used to predict the underground water TDS. Based on electrical characteristic analysis of sandstone reservoir, taking the influfential factors of the Archie’s Equation and creation mechanism of spontaneous potential (SP) as starting points, the theoretical relationship between the underground water TDS and formation resistivity (Rt) without considering the infuence of the porosity is modeled in this paper, and also the relationship between the underground water TDS and SSP in the same section of drilling well. Utilizing the apparent resistivity logging and static potential logging data, and employing the numerical fitting method, the relationship between groundwater TDS and conductivity is analyzed and determined, finally, the electrical parameters of determining the water quality and the regional evaluation of water quality are expounded in Daqing oil field,songliao plain Quaternary sandstone aquifer.
