Research and Testing of Hydraulic Vibration Production Technology

Hydraulic vibration production technology is a new EOR method. In recent years, research and application of the vibration production technology has been in a rapid progress. The structure and working principle of the hydraulic vibrator, with field test results, are described in this paper. Through field tests, and statistical analysis of oil increment of testing wells, it is considered that the low frequency, high amplitude hydraulic pulse waves, produced by using of a hydraulic vibrator, could relieve the blockage and contamination in reservoirs near the oil well. Thereby the oil production rate can get evidently increased, and keep stabilized.
