Abstract
In this paper, the basic theories of the Self-excited Oscillation Pulsed Jet Nozzle ( SEOPJN ) invented by the au thors are introduced. Then, some experimental results are shown. According to the results, using tricorn bits as sembled the SEOPJN to drill oil well, the rate o f penetration (ROP) increases by 8% - 77%, and the rate of the footage for tricorn bit increas es by 6.7% - 44%. Although the test was conducted in the water, good result was got in nature gas transporta tion. The volume of gas transportation could be increased by the Self-excited Oscillation Pulsed generator while the gas pressure drop could be decreased, since it significantly reduced the pressure loss during gas transportation.
