| 摘 要： | 针对地层压力低,热洗清蜡时洗井液大量进入地层,严重污染油层问题,研制了热洗清蜡油层保护器.该工具主要由1个皮碗胶筒和偏心球座构成,解决了洗井液进入地层的问题,有效地避免了对地层造成的污染.几十口井的现场应用表明,该工具使用时不影响正常生产或测试,停泵时,砂粒可直接沉降到尾管,不会在球座处堆积,工具结构简单,成本低. |

| Abstract: | In view of flushing fluid enter and contaminate formation during heat-washing paraffin in low pressure well,developed reservoir protector by heat-washing paraffin.It composed of a leather cup and bias ballseat,solved above problems.Application indicate that it doesn't affect production and testing,as pump off,sand will subside to tail pipe and doesn't accumulate to ball-seat.The protector has such characters as structure simple and low cost. |
| Keywords: | low pressure reservoir protector application |
