Problems solved by technology

Domestic research institutions have also carried out research on rotary steerable drilling devices on the basis of foreign technologies. Although directional drilling and azimuth adjustment can be realized in principle, many key technologies still cannot be broken through due to the lack of experimental research.
At present, there is no experimental simulation device for dynamic pointing rotary steerable drilling tools, so it is impossible to conduct experimental research

Embodiment 1

[0036]If it is necessary to load the drilling pressure to the tool, the oil pump will pressurize the oil chamber on the right side through oil hole two 12. The oil pressure pushes the cylinder hollow shaft 10 to transmit the axial force to the drill bit 1 through the transparent cover 25, the pressure sensor 26, the retaining ring one 27, the thrust ball bearing 28, the flange one 5, and the flange two 2. If unloading is required, oil hole two 12 releases pressure first, and then the oil pump pressurizes the left oil chamber through oil hole one 11 to achieve unloading effect.

Embodiment 2

[0038] If loading torque is needed, the hydraulic motor is delivered to the drill bit 1 by output shaft 17, flat key one 15, load shaft 19, flat key two 4, flange one 5, flange two 2, clip 3.

Embodiment 3

[0040] If the drill bit 1 needs to swing when loading, the drill bit 1 drives the parts except the baffle plate to swing in any direction. The baffle counteracts the axial reaction force generated by the axial force.

Abstract

The invention discloses a dynamic steering simulation device for a dynamic directional rotary steering drilling tool, which comprises a rack, a drill bit, a load shaft and a hydraulic motor, and is characterized in that an output shaft of the hydraulic motor is connected with the load shaft and transfers the torque to the load shaft, a cylinder is installed on the load shaft through a radial ball bearing ball ad used for providing an axial force for the load shaft, a plurality of universal balls are uniformly installed on check ring along the circumferential direction, one side of the universal ball is provided with a baffle plate used for counteracting an axial force applied by the hydraulic cylinder to the tool, and a contact surface of the baffle plate and the universal balls is a spherical surface; and experimental research on steering performance and other aspects of the dynamic directional rotary steering drilling tool can be performed through loading the axial force and the torque. The dynamic steering simulation device not only can be used for experimental research, but also can be used for performance testing for the directional rotary steering drilling tool.

Description

technical field [0001] The invention belongs to the field of petroleum drilling engineering, and in particular relates to a dynamic steering simulation device for a dynamic pointing rotary drilling tool. Background technique [0002] In order to meet the requirements of exploration and development of oil and gas resources, there are more and more wells with complex structures such as extended-reach wells, three-dimensional multi-objective multi-lateral wells, and horizontal wells with long horizontal sections. Conventional drilling technology can no longer meet the technical requirements of complex well drilling technology. Many problems, such as low drilling efficiency, poor borehole purification, poor well depth quality, and frequent downhole complex situations, have seriously affected the development of my country's drilling industry and oil extraction technology. Therefore, the rotary steerable drilling technology emerges as the times require, that is, the rotary steerab...
