Abstract

The invention discloses a tension and compression testing machine. The tension and compression testing machine comprises a main bearing frame, a mobile bearing vehicle, cylinder vehicles, connecting devices and push and pull oil cylinders. The mobile bearing vehicle is a mobile bidirectional bearing vehicle and is arranged in the middle of the main bearing frame; the two connecting devices are arranged at both ends of the mobile bidirectional bearing vehicle; the two cylinder vehicles are connected with both ends of the main bearing frame through the two push and pull oil cylinders; one of the push and pull oil cylinders is a large-tonnage push and pull oil cylinder, and the other push and pull cylinder is a small-tonnage push and pull oil cylinder; the minimum value of the action force of the large-tonnage push and pull oil cylinder is smaller than or equal to the maximum value of the action force of the small-tonnage push and pull oil cylinder. The tension and compression testing machine greatly enlarges the testing range, thereby being applicable to testing not only medium-tonnage tools, but also small-tonnage tools as well as large-tonnage tools.

Description

technical field [0001] The invention relates to a device for detecting the strength and rigidity of a drilling tool, a cementing tool and a well completion tool, in particular to a tension-compression testing machine. Background technique [0002] Drilling tools, cementing tools and well completion tools need to carry out axial tension or compression test of the whole machine before going into the well, especially some new tools must be subjected to axial tension and compression testing to simulate well conditions before going into the well. In addition, for conventional tools, the integrity rate of the tools is also required, so some conventional tools also need to do tension and compression tests before going into the well. After the tools are tested by the tension and compression testing machine, the unqualified tools can be eliminated, and the downhole accident rate can be reduced by using qualified tools, thereby improving construction efficiency and reducing constructi...
