Paper Title:
Research on High Temperature Mechanical Properties of Casing in Complex Environment Deep Well
  Abstract

To analyze the effect of high temperature on material properties of steel casing Q125 and V140 in complex deep wells, some experiments of casing material have been done at the temperature of room temperature to 350°C, and based on the former results the material property model of high-grade steel casing under the effect of temperature was established. To facilitate the design of oilfield, uniform strength reduction factor at 150°C and 200°C was given, which was applied to casing string and tubing string design under high temperature. Taking an ultra-deep field as an example, the results show that casing mechanical properties decreases with the temperature increasing; in the design process of high temperature well, the temperature effect is needed to consider.
