Ｙ３４１—１１５注水封隔器工作时的移动严重影响分注的成功率，移动的原因主要是封隔器上下的压力不同，产生的压差所至。文中对其移动距离进行了理论计算，对无锚定工艺管柱存在的问题进行总结，提出了解决深井高压注水时防止封隔器蠕动的方法，一是增加封隔器的用量；二是加水力锚和水力卡瓦。该工艺技术在大港南部油田３３口分注井中应用获得较大的效益。
Y341-115 water packer movement during the operation seriously affect the success rate of dispensing, the main reason is the packer pressure up and down, the resulting pressure difference. In this paper, the moving distance is theoretically calculated, and the existing problems of the non-anchored process pipe string are summarized. A solution to prevent the peristalsis of the packer against the high-pressure water injection in the deep well is proposed. One is to increase the amount of the packer; the other is to add water Anchor and hydraulic slip. The process technology in the south of Dagang oil field injection wells 33 applications to obtain greater benefits.
