低频脉冲振荡解堵技术是通过在井服液体中，瞬时高压放电产生低频脉冲波选择性地冲击处理井眼地层，可清除孔道中的沉积堵塞物，并使地层产生新的微裂缝，进而使液体由滞留区向排济区流动，达到解堵增产的目的。该仪器是在对比分析国内外振动采油仪的基础上研制的。其优点：可与常规测井电缆匹配，不需配接专用电缆；仪器一次下井即可完成校深定位和振动施工作业；仪器井下放电电压为3000v，4000v，5O刀v可调，每脉冲放电能量为3000J－3500J，而国外同类仪器的放电电压为3000V，每脉冲放电能量为500）－1000）。应用证明，该仪器结构简单，配套设备少，易于操作和施工。与其它油井作业措施相比，具有费用低，见效快的特点。
The low-frequency pulsed oscillation plugging technology selectively impacts the wellbore formation by generating low-frequency pulsed waves in the well-service fluid, which can clear the sediment plugging in the channels and cause new micro-cracks in the formation, The liquid flows from the stagnant area to the drainage area to achieve the purpose of removing plug and increasing production. The instrument is developed on the basis of comparative analysis of domestic and foreign vibration oil recovery instrument. Its advantages: can match the conventional logging cable, without the need to connect a dedicated cable; instrument once down to complete the school deep positioning and vibration construction work; instrument downhole discharge voltage 3000v, 4000v, 5O knife v adjustable, each pulse discharge Energy 3000J-3500J, while the discharge voltage of similar instruments abroad 3000V, discharge energy per pulse 500) -1000). Application shows that the instrument has the advantages of simple structure, less supporting equipment and easy operation and construction. Compared with other well operations, it has the characteristics of low cost and quick response.
