低频脉冲振荡解堵仪的研制与应用

Development and Application of Low Frequency Oscillation Deplugging Tool

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。

篖ow frequency pulse aseillahon depluaing tecboque can be uwh to clear the pluaing dpeition in the charml andto make the targt layer creat new ndcffefiactUre. Therefore, the fluid can flow dri Stagnant area to discbo area.This technique uses the fow boency puIse creaed by instantaneoUs high voliag dischop to imPat the selected layer,so the purpose enhancing meovery can be achieved. Based on the analysis and cOInParison of hehc and foreign vibrating axovery tools, a new kind of vibrahng meovery tool is deVfoPed. This kind of ed can match conventional beging cable, and can finish depth poSihon and vibration woIk in one job. thee dischaIg voltages of 3 an V, 4 an Vand 5 (XX) V can be selected for the too and the dischop eneny Per ptilse is 3 an J ~ 3 5oo J. The dischaIge voltageof foreign tool is only 3000 V and the dischop energy Per Pulse is 5(X) J ~ l an J. The smicbe of the deVfoped toolis simple and its operation is easier.
