摘要
Abstract
For horizontal wells and high angle wells offshore ,LWD resistivity log is affected by mud invasion , resistivity anisotropy and other factors , leading to the apparent resistivity departing from the true formation resistivity ,a 3D resistivity inversion method is proposed and designed to get the accurate formation resistivity profile and borehole stratigraphic position , w hich provides reliable parameters for the reservoir evaluation and supplies effective protection for oil field development and production .For Halliburton ADR azimuthal resistivity logging data , the Marquardt method is employed to compute invasion radius , the flushed zone resistivity (invaded formation) ,and the virgin horizontal resistivity ,vertical resistivity ,boundary layer distance (horizontal well) etc .The results of numerical simulation show that the accuracy of the inversion method is high ;the inversion results are accurate and reliable . T he 3D resistivity inversion is very important for the reservoir stratum evaluation and the calculation of reserves .关键词
