摘要： Thin flexible piezoelectric transducers are bonded to or imbedded into oilfield tubular members or structural members. The transducers may be used to telemeter data as acoustic waves through the members. By proper spacing of transducers and phasing of driving signals, the transmitted signals can be directionally enhanced or encoded to improve transmission efficiency. The transducers may be used for health monitoring of the tubular or structural members to detect cracks, delaminations, or other defects. The flexible transducers are very thin so that overall dimensions of tubular or structural members are essentially unchanged by incorporation of the transducers.

摘要： Electrical connections between different materials. An electrical connection system includes electrical components and an electrical connection between the electrical components. The electrical connection includes a functionally graded material. A method of making an electrical connection between different materials includes the steps of: providing an electrical component which includes a material; providing another electrical component which includes another material; and electrically connecting a functionally graded material between the electrical components. An electrical connection system includes an electrical component and a functionally graded material electrically connected to the electrical component. The functionally graded material provides a gradual transition between at least two dissimilar materials.

摘要： Electric power is generated downhole by changes in annulus pressure. In a described embodiment, a system for generating electric power includes a piston, an accumulator, a reservoir of hydraulic fluid, a turbine, and a generator. A change in annulus pressure causes displacement of the piston due to a pressure differential between the annulus and the accumulator. Piston displacement causes the hydraulic fluid to flow through the turbine, thereby driving the generator to generate electricity.

摘要： An electromechanical transducer formed by an electrical and mechanical combination of a piezoelectric device and a magnetostrictive device. The two devices are electrically coupled so that their capacitive and inductive reactances approach a balance to provide an essentially resistive combined input at a selected frequency. Efficiency of circuits driving the transducer is improved. The devices are mechanically coupled so that the mechanical outputs add or reinforce each other. Two transducer pairs may be used in a two frequency telemetry system with each pair tuned to one of the frequencies for optimal reactance balancing and transduction efficiency.
