Abstract

The invention relates to a screw drilling tool, a vertical drilling tool testing method and well inclination simulation testing equipment, and relate to the technical field of petroleum equipment. Thetesting equipment comprises a main bracket, a push-pull device and an angle measuring device, wherein the first end of a tested tool is suspended and pivoted to the main bracket, one end of the push-pull device is connected with the main bracket, the other end of the push-pull device is connected with the tested tool, and the push-pull device is used for pushing or pulling the tested tool to makethe tested tool incline; and the angle measuring device is connected with the tested tool and used for measuring the offset distance of the second end of the tested tool. The testing method includesthe following steps that the first end of the tested tools is suspended and pivoted to the main bracket; the second end of the tested tool is pushed or pulled to make the tested tool incline; the offset distance of the second end of the tested tool is measured; and according to the offset distance, the inclination angle of the tested tool is calculated. By means of the testing equipment and the testing method, the tested tool can incline at different angles, and the working condition that the tested tool deviates from the vertical plane due to inclination of a well wall is simulated.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a testing method for a screw drilling tool and a vertical drilling tool and a simulated well deviation testing device. Background technique [0002] In oil and gas development, with the vertical drilling requirements of high-steep structures, large dip angles and other easily-deviated formations, the development of downhole anti-deviation, correction and speed-up tools has been accelerated, and the newly developed tools need to verify their anti-deviation and correction capabilities. However, it takes a long period and high cost to find a suitable test well for tool testing, and it is not easy to measure the influence of well inclination angle on tool deviation correction ability. [0003] Therefore, it is necessary to design a test method for screw drilling tools and vertical drilling tools and simulated well deviation test equipment, so that the tested tools can be ...
