Abstract

The invention discloses a deep water surface casing running tool relief simulating experimental device and method. The deep water surface casing running tool relief simulating experimental device comprises an experimental frame, a low-pressure well head, a deep water surface casing running tool, a rotating motor, a lifting motor device, a coupler, a data collector and a computer. An output shaft of the rotating motor and an output shaft of the lifting motor device are provided with a torque sensor and a tension sensor correspondingly. Multiple anti-rotation pin sensing sheets are arranged in the deep water surface casing running tool. The torque sensor, the tension sensor and the multiple anti-rotation pin sensing sheets are connected with the computer through multiple data lines. By the adoption of the deep water surface casing running tool relief simulating experimental device and method, by means of experiment stress analysis of operations, such as locking, relief and recycling, conducted on the deep water surface casing running tool, basis is provided for making a plan to optimize pin arrangement, and then the safety, efficiency and accuracy of the deep water jet operation of the deep water surface casing running tool are improved.

Description

technical field [0001] The invention relates to the technical field of offshore oil and gas drilling, in particular to a simulation experiment device and method for releasing a deep-water surface conduit into a tool. Background technique [0002] Deepwater drilling generally refers to drilling with a depth of more than 900 meters in offshore operations. During the process of deepwater drilling in the ocean, due to the low strength of the shallow undiagenetic strata on the surface of deepwater drilling, it is prone to collapse. The deepwater surface conduit is installed during the entire deepwater oil well construction process. The first layer of casing, which provides structural support for all subsequent casings and wellhead equipment, is the "throat" of deepwater drilling. [0003] The deep water surface conduit jetting running technology is a key link in the construction of deep water drilling projects. This technology can realize continuous drilling through multiple step...
