【 摘 要 】

The paper focuses on downhole vibration source used for wave generation in an oil stratum in order to increase oil recovery and stimulate hydrocarbon flow in a well. Simulation results of pre-shock compressive vacuum resistance to a hammer in an electromagnetic shock unit in a downhole vibration source are presented. The effect of axial hole in a hammer on induced compression is analyzed. Experimental data on changes in coil electromagnetic traction are presented depending on axial hole diameter in the hammer. Based on the effect of hammer hole diameter on compressive vacuum resistance and coil electromagnetic traction the present research findings can be of great use in designing an electromagnetic shock unit.
