摘　　要：随着油气勘探开发的不断发展,井深逐步加大,压力、温度也逐步升高,伴随着蒸汽吞吐、蒸汽驱等技术的应用,由于地层流体与环境温度的巨大差异,套管、水泥环受热膨胀导致的带压问题日益突出,导致套管损毁、水泥环破坏、安全性降低,影响作业生产,直接威胁到井筒完整性。深井条件下套管形变实验装置可以在室内条件下,通过模拟实际深井条件,测量高压、高温条件下套管的形变、应力,检测水泥环的破坏情况,分析套管的形变、应力变化规律。With the continuous development of oil and gas exploration and development, the well depth is gradually increased, and the pressure and temperature are also gradually increased. With the application of steam huff-puff, steamflood and other technologies, due to the huge difference between the formation fluid and the ambient temperature, the pressure problems caused by the thermal expansion of casing and cement-sheath are becoming more and more prominent, resulting in casing damage, cement-sheath damage and reduced safety, affecting the operation and production, It directly threatens the integrity of the wellbore.The casing deformation experimental device under deep well conditions can measure the casing deformation and stress under high pressure and high temperature conditions, detect the damage of cement sheath and analyze the variation law of casing deformation and stress under indoor conditions by simulating the actual deep well conditions.
