摘　　要：振动酸化复合解堵技术是把井下双重震源振动解堵技术与化学方法油层处理技术有机结合,通过物理、化学的双重作用,综合改造治理欠注层,提高注水井近井底地带渗透性,达到降压增注效果的一项油层改造新工艺。本文介绍了该工艺的原理、选井条件、设计原则以及施工工艺。该工艺在东辛油田应用,取得了明显的经济和社会效益,具有较好的推广应用价值。The technology of compound deplugging by vibration acidization is to combine downhole dual source vibration deplugging with chemical treatment and to stimulate under-injected reservoir through both physical and chemical functions, thus to improve permeability in the vicinity of injectors, reduce pressure and increase injection. This paper addresses the theory, well selection conditions, design principle and operation process of this technology. The application of the technology in Dongxin oilfield has achieved notable economic and social benefit. It is worth of popularizing.
