APPARTUS AND METHODS FOR ESTIMATING DOWNHOLE FIELD COMPOSITIONS |
摘要 |
An apparatus and method for estimating a property of a species of the hydrocarbon in a downhole fluid are provided. In one aspect, the method may include: imparting a magnetic field on the fluid to align nuclei of the fluid with a direction of the primary magnetic field; imparting a perturbing radio frequency signal on the fluid to excite the nuclei of the fluid; detecting a radio frequency signal emitted by the excited nuclei of the fluid; estimating a frequency shift between the perturbing radio frequency and the detected radio frequency; and estimating using the frequency shift a property of one or more species of the hydrocarbons in the fluid. |
