This invention relates to the field of laser cutting equipment technology, and discloses an intelligent laser cutting device and method for processing seamless steel pipes. The intelligent laser cutting device for processing seamless steel pipes is characterized by comprising: a machine tool body, a laser cutting mechanism, a front-end rotating fixture, a rear-end feed fixture, a control console, and an auxiliary support system; the auxiliary support system includes: a base, a rolling contact module, an avoidance drive module, a height adjustment module, a parameter sensing module, and a control module; the base is movably mounted on the machine tool body along the pipe's moving direction; the rolling contact module is mounted on the base and includes at least two side-by-side support rollers and a spacing drive mechanism for driving the two support rollers to move synchronously towards or away from each other; the avoidance drive module is connected to the base and is used to drive the rolling contact module to switch between a support position and an avoidance position.

This invention relates to the field of cementing equipment technology in oil extraction, specifically a casing centralizer for oil extraction cementing. It includes two identical centralizer mounting bases, a first centralizer mounting base and a second centralizer mounting base. Multiple inner constraint spring plates are distributed between the two bases and combined to form a cylindrical frame. Outer main spring plates are correspondingly located on the outer sides of the inner constraint spring plates. The centralizer also includes a curvature adjustment mechanism and wellbore inner diameter detection and control equipment. The curvature adjustment mechanism drives a sliding column via a hydraulic system, pulling a curvature adjustment rope to adjust the distance between the outer main spring plates and the inner constraint spring plates. This centralizer can dynamically adapt to the outer diameter according to the wellbore inner diameter, providing precise and stable adjustment. It reduces downhole movement friction and component wear, ensuring the casing remains centered, effectively improving cementing construction quality and equipment operational reliability, and adapting to complex and harsh downhole conditions.
