Application of Deep Wave Excitation Water Injection Technology in Jingbian Oilfield

As a low porosity and low permeability reservoir, Jingbian oilfield is mainly developed by water flooding. In the long-term process of water flooding, many factors caused the formation plugging, which resulted in injection well water absorbing capacity decline to affect the effect of water flooding. In order to relieve the blockage of the reservoir in the water flooding process and recover the reservoir permeability to reach the normal water flooding capacity, deep wave excitation water flooding technology was introduced and applied to 10 wells as a test. The result of the field test shows that the period of validity of deep wave excitation water flooding technology is more than 3 times longer than that of the conventional blockage removal technologies.
