| Abstract: | MR Explorer(MREx) is a multifrequency,multifield gradient,side looking NMR logging tool,newly developed by Baker Atlas company. Compared with other kinds of NMR tools,MREx is characterized by unique design in magnetic iron and antenna,novel pulse sequences,multiple measurement frequency,simple observation mode and so forth. Moreover,Objective oriented NMR logging concept is led in,and logging activations is changed to data acquisition package. Within each package,there are multiple echo trains whose acquisition parameters are pre defined to cover a wide range of variations,the logging engineer is not required to make downhole adjustments and carefully choose acquisition parameters. |
