The invention discloses a vibration simulation test device for an oil and gas well pipe string, which is composed of a power module, a pressurization module, a wellbore module, an excitation module and a load module. The front end of the power module is a pressurization module, a wellbore module, an excitation module and a load module in sequence . The power module of the oil and gas well pipe string vibration simulation test device of the present invention can provide input speed and driving torque to drive the drill bit to rotate, and the pressurization module can provide the drilling pressure for the drill bit to form axial displacement. For the contact state between well walls, the excitation module can simulate the axial, circumferential and radial excitation loads, and the load module can simulate the interaction between the drill bit and the rock. The oil and gas well pipe string vibration simulation test device of the present invention can simulate the real downhole drill string boundary conditions, and the different function realization mechanisms are all modular designs, which can be disassembled and combined according to different simulation experiment requirements, increasing the application of the test device sex.
Description
technical field [0001] The invention belongs to the technical field of petroleum and natural gas engineering, and in particular relates to the design of an oil and gas well pipe string vibration simulation test device, which is mainly used in the oil and gas well pipe string vibration simulation experiment research. Background technique [0002] With the continuous exploration and development of oil and gas resources, traditional oil and gas resources are gradually exhausted, and drilling engineering is gradually developing towards the exploitation of unconventional oil and gas resources. Under the conditions of new oil and gas resources exploitation, drilling technology is facing more technical challenges. In order to adapt to the development of new oil and gas resource exploration and development technologies, and to improve the drilling efficiency of oil and gas well drilling engineering and ensure the safety of drilling production operations, relevant research institution...
