摘　　要：多层系地层常因固井质量差，造成油气水井的层门或管外串通，影响对各层的认识和评价。采用水泥承转器挤水泥技术能防止挤水泥浆倒流，且多余的水泥浆能从工具的上部反循环至地面。简述了该工具的结构和工作原理，以及挤封串作业的基本程序和注意事项，并以华北油田雁43井挤水泥封管外串槽的实例验证了其可行性。Because of the low quality well cementing,there often is present crow flow between layers or out of the tube strain. This always effect on understand and evaluation of every layer. Using cement retainer squeezing technology can prevent the cement backward flow,and cam let the residual cement through the upper party to recycle to the ground. The tool structure work theory program and warning of squeezing cement are also introduced in this paper. Taking Yan-43 well as successful example. we verified the feasibility of this technology.
