摘　　要：冲击波解堵综合利用机械学、水力学、化学、热力学等原理,能解除油水井近井地带的污染,提高油层渗流能力和单井产能。该技术具有工序简单、操作方便、费用较低、施工时间短的优点,目前在解堵增产措施中得到广泛应用。针对该技术在低渗透油藏的实际应用情况,结合具体油井,对其解堵效果和影响因素进行了分析。By comprehensive using of the theories of mechanics, hydraulics, chemistry and thermodynamics, the method of deplugging by shock wave can remove the contamination in the vicinity of oil and water wells to improve percolation and single well productivity. This technology is easy to operate, convenient, low cost, and takes short operation time. It is now widely used as a stimulation measure. The deplugging effectiveness and influence factors of this technology are analyzed in accordance with the application in low permeability reservoirs.
