Abstract

The invention relates to a rotary drilling large-scale experimental bench with adjustable well deviation and vertical-depth ratio which is used to conduct simulation drilling on highly-deviated wells, directional wells and horizontal wells. The experimental bench includes a power end system, a wellbore system, a well bottom micro drilling system, and a data acquisition system. A hydraulic lifting device, a telescopic slide rail frame and a detachable mobile slide rail frame constitute a base of the whole experimental bench. The power end system is composed of a hydraulic servo mechanism, an adjustable-speed motor, a fluid inlet cavity, and a quick adapter. The wellbore system is composed of a PVC pipe, a glass pipe, and a steel wire hose. The well bottom micro drilling system is composed of a micro drill, a rock box, a rock mounting guide rail, and a rock box guide rail. Experimental study of the drilling kinetic parameters, friction torque and whirling and buckling behavior of a rotary drill string can be conducted under various fluid circulation mediums, various drilling conditions and various wellbore structures. The experimental bench is simple to operate, and has complete functions.

Description

technical field

[0001] The present invention relates to a large-scale scale experimental platform for simulated drilling of highly deviated wells, directional wells and horizontal wells. The experimental device can conduct drilling dynamic parameters, Experimental research work on frictional torque, drill string whirl and buckling behavior, etc. Background technique

[0002] In the research process of oil and gas drilling related technologies and downhole tools, it is often difficult to effectively carry out large-scale simulation drilling experiments due to the limitation of experimental conditions, so that it is impossible to obtain key technical data to support subsequent related research. Although it is the best experimental plan to conduct experimental wells or on-site drilling experiments, the high cost, technical requirements and safety factors have become the main reasons for restricting large-scale experiments. Therefore, it is necessary to find a more economical an...
