Apparatus and Method for transporting at least the property of nuclear Magnetic Resonance Of geological formations surrounding a Borehole

摘要

The present Invention relates in general to an apparatus and Method for Measuring the properties of nuclear Magnetic Resonance Of A Training geologicaatravesada by Drilling through the geneRation of gradient Echoes. The puedereali Measurement While Drilling or using a tool for Wired.The Apparatus applies a Static Magnetic Field, ba, with a volume of Polarized Nuclei formation Sedimentary hidrogenososdentro Liquid of the formation.The Apparatus aplicaun. When Magnetic Field, BB, in a volume of Formation. Magnetic Fields, ba and bb are sustancialmenteortogonales in volume of Formation.A Change in the Polarity of the magnetic field, BB, reverses the direction of precession of a train losnucleos generandoasu00ed Echoes gradients.Each gradient echo signal is transformed into the frequency domain and frequency of the signal is projected according to radial position in the volume of the formation to generate an image of laforInformation.D number of Formation Properties, such as the coeficientede effective Diffusion of Fluid from the formation, the longitudinal relaxation time,The Spin - Spin Time ratio and Porosity can be estimated according to him three ecosgradientes.
