ABSTRACT:
A casing in an oil well is constructed to provide for the flow of oil in the well. The casing cylindrical and may be perforated. The casing is resonant in a hoop mode at a particular fundamental frequency such as approximately 400 hertz. A transducer includes a transducer member disposed within a tubing in spaced relationship to the tubing. The transducer member may be a ceramic slotted at one end and supported by the tubing at the other end. A ring may envelope the ceramic member and may be slotted at the same position as the ceramic member. The tubing may be filled with a fluid which provides dielectric properties and operates to transmit vibrations from the transducer to the tubing. The transducer may vibrate in the hoop mode at the fundamental frequency of resonance of the casing. These vibrations are transmitted to the casing through the fluid in the tubing, the tubing and the oil in the casing to produce a resonance of the casing at the particular fundamental frequency in the hoop mode. Wet concrete is disposed around the casing. The transducer is then moved slowly upwardly, while vibrating the transducer, to eliminate any gas, oil or mud pockets in the concrete while the concrete is still wet. The upward movement of the transducer may be temporarily interrupted at positions where the gas, oil and mud pockets are known or suspected to exist.
