摘要： The present disclosure relates to embodiments of a device and method for inspecting and detecting characteristics of tubing and devices attached to tubing. More particularly, embodiments of a device and method are disclosed for inspecting a number of tube walls surrounding an innermost tube wall. In embodiments, an inspection device may induce an eddy current in surrounding tube walls by producing an electromagnetic field, wherein the induced eddy current may be recorded and analyzed for aberrations. Eddy currents may be produced by a sensor array comprising a hybrid magnetic matrix core capable of inducing an electromagnetic field at a high saturation point while maintaining good linearity. The eddy current decay and diffusion in the tube walls may be recorded, specifically recording voltage in embodiments, which may produce a function of the tube thickness and electromagnetic properties (e.g. metal conductivity and magnetic permeability) and the configurations of tubes.

摘要： A method and apparatus for evaluating light-weight cement (LWC) bond conditions in production well in presence or absence of the tubing. The apparatus includes a tool string that can be lowered into the casing or the tubing. The tool string includes a segmented transducer ring matrix to excite the surrounding medium resulting in vibrations. The tool string further includes an impedance measurement circuit that can determine natural resonance frequencies of the structural components. The impedance measurement circuit can determine certain non-harmonic resonance mode shapes for mechanical impedance measurements that are sensitive to the LWC bond conditions. A machine learning model can be used for segmented impedance measurements to correct effects from the tubing eccentricity inside the casing. Lab calibration generates bond index mapping table and the field logging impedance measurement data can be processed into the bond indexes to further evaluate LWC bond conditions.
