由于自然地震的影响,油水井的产量发生波动,使人们受到启示,从而研究应用了人工地震采油技术。通过理论分析,人工振源设计改造,室内和现场试验及振动参数测试,揭示了人工振动增产的机理,指出振动增产作用是通过地面振动使油层在固有频率下产生共振,加快地层中流体的流动;改变储集层油、气、水的重新分布;改变岩石表面润湿性;有利于清除油层堵塞,提高渗透率。 Due to the impact of natural earthquakes, the production of oil and water wells fluctuate, so that people are enlightened to study the application of artificial seismic oil production technology. Through theoretical analysis, artificial vibration source design and reformation, indoor and field test and vibration parameter testing, the mechanism of artificial vibration stimulation is revealed. The effect of vibration stimulation is to make the oil layer resonate at natural frequency through ground vibration and accelerate the fluid flow in the formation ; Change the redistribution of oil, gas and water in reservoir; change the wettability of rock surface; help to clear the blockage of oil layer and improve the permeability.
