摘要： A wellbore fluid inductance monitor is disclosed, which operates at an end of a tubular in a wellbore. The wellbore fluid inductance monitor comprises an inductor in an electrical circuit. A magnetically doped portion of wellbore fluid, which may he a hydraulic fluid or cement slurry, is introduced into the wellbore during a reverse cementing or other cementing operation. The magnetically doped portion of wellbore fluid contains a dopant that alters at least one of a magnetic permeability and conductivity. The wellbore fluid inductance monitor detects the proximity magnetically doped portion of wellbore fluid based on altered electrical characteristics of the inductor. Based on the detection, the wellbore fluid inductance monitor triggers a wellbore operation which is detectable at a cementing controller and the cementing operation can be stopped or otherwise completed based on the determination that the cement slurry has reached the end of the tubular.

摘要： Various embodiments include a method for generating a pulse for use in nuclear magnetic resonance (NMR) logging. One such method generates the pulse by adjusting one or more of pulse parameters including a pulse shape, a pulse amplitude, a pulse phase, and/or a pulse frequency. The generated pulse produces a substantially uniform nuclear spin saturation or nuclear spin inversion response from a fluid. A wait time between the pulse transmission and an echo that indicates spin equilibrium has been achieved is substantially equal to a T1 time indicating characteristics of the fluid.
