The yield strength of the casing directly affects the anti-extrusion performance of the casing. During the processing of casing hole, metal phase transformation may happen in the material near the hole. Thus the yield strength is no longer uniform in the whole casing, which affects the crushing strength of the casing. Taking the P110 casing as an example, the crushing strength of the complete casing and the machined hole casing under the same working conditions were compared. And as a reference group, the influence of the area of the phase transition region and the yield strength of the phase transition region on the crushing strength of the machined hole casing were analyzed. The results showed that the machined hole changed the yield strength of the material, which affected the anti-extrusion performance of the casing. When the yield strength of the metal phase transition region reduced, the extrusion strength of the machined hole reduced, and when the yield strength of the metal phase transition region increased, the extrusion strength of the machined hole increased. And the effect of the phase transition region of the machined hole casing on the extrusion strength of the machined hole casing was gradually weakened with the increase of the yield strength in the phase transition region.
