冲击波解堵原理是利用固体药剂在井底燃烧产生的高温高压能量,通过射孔通道作用油层,使油层产生多条辐射状微裂缝,油层发生剪切错动,破碎的岩石颗粒充填裂缝,适合低渗透油藏作业过程中造成油层污染和伤害等因素造成的油层堵塞进行解堵,能有效的解除近井地带的油层污染,改善油层渗透性,增加油层出油剖面,提高油井产能,具有良好应用前景。
Blasting plugging principle is the use of high-temperature high-pressure energy generated by combustion of solid pharmaceuticals in the bottom of the hole, through the perforation channel action of the oil layer, the oil layer produces a number of radial micro-cracks, the reservoir shear shear dislocation, broken rock particles fill cracks, suitable Low permeability reservoir operation caused by oil pollution and damage caused by blockage plugging plugging, which can effectively relieve the oil well near the well zone pollution, improve the permeability of the reservoir, increase the reservoir oil profile and improve well productivity, with good Application prospects.
