- Abstract
The fixed clamp should be installed inside the BOP stack for sectional blockage and tubing pulling job. When there is combined string in downhole, it causes inconvenience in replacing slips of different specifications because of pressure in BOP stack. To solve the problems mentioned above, variable diameter slip was invented. Different arc’s central angle model of slip was set by ANSYS, the oil tube was divided by sweep while the slip was divided randomly. The analysis shows the arc’s central angle for clamping ø73 oil tube is 106°and the clamping force meets operation needs and the design requirements.
