Abstract

The invention relates to a single testing device and method for a deepwater drilling marine riser test. The testing device is characterized by comprising a loading device, a data acquisition analysis and control system and a marine riser test single piece; the loading device mainly realizes a loading function through a lifting device and an electromagnet loading device; a clamping block, a connector and a connecting flange which are included in the loading device are connected in sequence and are suspended on the upper end surface of a lifting platform through a chuck; the electromagnet loading device comprises an electromagnet, a damping pad, an adjuster, an adjusting bolt and a double-end stud and is fixed on a fixed bracket; the fixed bracket is welded on a base of the lifting platform; the data acquisition analysis and control system can realize data acquisition and control of a three-component force instrument sensor, a high-speed measurement system, an electromagnet and the lifting platform, an upper end flange of the three-component force instrument sensor is connected with a connecting flange, the lower end of the three-component force instrument sensor is connected with the marine riser test single piece, and the lower end of the marine riser test single piece is in contact with the electromagnet; the high-speed measurement system is arranged on one side of the marine riser test single piece, and basic parameters of the marine riser test single piece are obtained based on the Newton's second law, the Hooke's law and the logarithmic attenuation rate method.

Description

technical field [0001] The invention relates to a marine riser suspension dynamics test device and method, in particular to a deep-water drilling riser test single test device and method. Background technique [0002] The offshore deepwater drilling riser system is the key equipment for offshore oil and gas exploration and development. When the environmental load exceeds the riser operation limit or the interwell displacement operation, the riser system and the blowout preventer or wellhead are released and enter the suspension mode. The riser system in suspension mode is stimulated by platform motion and environmental loads, resulting in a relatively severe dynamic response. Accurately grasping the dynamic response law of the riser system is particularly important for safe production operations and personnel safety. [0003] At present, a large number of theoretical studies have been carried out on the riser system under suspension mode at home and abroad, but there are re...
