COMSOL software is used to simulate the vibration mode and calculate the resonance frequency. Then the finite element method is used to explore the impact of the drill collar on the acoustic field radiated by the transducer and optimize the directivity of the monopole mode by changing the coupling material between the transducers.

2015-02-20CHAPTER-2 DRILLING FLUIDS Drilling fluid -mud - is usually a mixture of water, clay, weighing material and a few chemicals. Sometimes oil may be used instead of water, or oil added to the water to give the mud certain desirable properties. Drilling fluid is used to raise the cuttings made by the bit and lift them to the surface for disposal.
