歇福尔13-5/8"球形胶芯防喷器的设计探讨

Research on Design Defects of Shaffer 13-5/8" Rotating BOP

旋转防喷器是实施欠平衡压力钻井的关键设备。针对歇福尔13-5/8"活塞与隔离环连接密封部位的结构加以改进,增设去除沙石单元。通过实验数据合理选择材料,结合工况条件下的理论计算公式进行强度校合。

Rotary BOP is the key implementation in underbalanced drilling. In this paper, aiming at the improvement on the sealed structure of parts between its piston and connecting isolated ring. It has a reasonable choice of experimental data which theoretically calculate formula combining with the strength check under working conditions.
