摘　　要：Y211-115封隔器是在RTTS封隔器基础上改进的,增大了通径,增加了一个胶筒,使高压密封更可靠。水力锚采用防止上顶的尖齿锚爪结构,增加了固定管柱的稳定性,提高了储层的加砂能力。经现场实验,总结出Y211-115封隔器坐封高度与坐封载荷对应的实用数据,使之坐封成功率达到100%,为“三低”油田增储上产提供了有利保证。Based on RTTS packer, Y211-115 packer is modified to enlarge inner diameter and add one element that makes its seal in high pressure to be reliable. Hydraulic anchor uses tine toothed structure against upward movement to raise the steady to firm testing stem and increase adding sand capacity for formation. By field test, practicality data of setting height of Y211-115 packer corresponding to its setting weight has been summarized which makes its successful ratio is 100% and provides a good guarantee for increasing potential production of three low oilfield.
