Embodiment Construction

[0018] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0019] Such as figure 1 and figure 2 As shown, the device for testing the torque of the top drive of the present invention includes an impeller-shaped device 1 and a drill pipe 3 . Wherein, the device 1 has several blades 11 and a hub 12 , so that the blades 11 are vertically fixed on the outer surface of the hub 12 . This can effectively prevent the device 1 for testing the torsion of the top drive from generating upward thrust or downward pull during rotation, thereby avoiding damage to the top drive 2 . One end of the drill rod 3 is threadedly connected with one end of the hub 12, and the other end of the drill rod 3 is connected with the top drive 2 (such as Figure 4 shown).

[0020] Specifically, in this embodiment, a drill pipe threaded hole 121 is provided at one end of the ...

Abstract

The invention discloses a device for testing a top drive torque. The device comprises an impeller-shaped device and a drilling rod, wherein the impeller-shaped device is provided with a plurality of blades and a wheel hub, and the blades are vertically fixed on the outer surface of the wheel hub; and one end of the drilling rod is in fixed connection with one end of the wheel hub, and the other end of the drilling rod is connected with a top drive. The device provided by the invention is used for testing the top drive torque, and is simple in structure and safe and highly efficient in usage. In addition, the device is capable of substantially reducing the cost and risks of offshore drilling operation.

Description

technical field [0001] The invention relates to a testing device, in particular to a device for testing the torque of a top drive. Background technique [0002] The top drive, or top drive, is a commonly used top drive drilling device. The most critical economic index of the drilling platform is the drilling speed of the drill bit, and the factors that affect the drilling speed are the drilling speed (rev / min) and continuous torque of the top drive, that is, the test top drive produces at a constant speed. The size of the continuous torque is one of the key tests to test the performance of the top drive. [0003] At present, the following problems exist in the test of top drive torque: [0004] 1. During the construction and commissioning stage of the platform, it is impossible to test the rotational torque of the top drive under real drilling conditions. [0005] 2. During the official drilling operation, the torque test of the top drive device cannot be carried out. If ...
