Problems solved by technology

The borehole diameter of geological drilling is generally small. Affected by the size of the tool, the radius and length of the eccentric block are small, which leads to the critical deflection angle of the eccentric block at a small well deviation. Tool reduces or loses skewing ability

Abstract

The invention discloses a mechanical reinforcement stabilized platform for an automatic vertical drilling tool, and relates to the technical field of geological drilling equipment. The mechanical reinforcement stabilized platform comprises a shell; a lower eccentric weight, a pressure compensation structure, and an adjusting structure which are rotationally connected with the shell are sequentially arranged in the shell from bottom to top; the adjusting structure comprises an inner cylinder valve and an outer cylinder valve arranged at the outer side of the inner cylinder valve in a sleeving mode and rotationally connected with the inner cylinder valve; the lower eccentric weight, the pressure compensation structure, and the outer cylinder valve are fixedly connected in sequence; an uppereccentric weight is fixedly connected with the inner cylinder valve; the upper eccentric weight is rotationally connected with the pressure compensation structure; and the adjusting structure is usedfor adjusting the deflection angle of the upper eccentric weight and the lower eccentric weight. According to the mechanical reinforcement stabilized platform for the automatic vertical drilling tool,an upper disc valve is controlled through the double eccentric weights (the upper eccentric weight and the lower eccentric weight), and the lower eccentric weight with large interference is controlled through the upper eccentric weight with small interference, so that the underground closed-loop adjustment of the relative positions of the upper eccentric weight and the lower eccentric weight canbe achieved through the inner cylinder valve, the outer cylinder valve and a driving structure, and the control precision is high.

Description

technical field [0001] The invention relates to the technical field of geological drilling equipment, in particular to a mechanical boosting and stabilizing platform for automatic vertical drilling tools. Background technique [0002] At present, drilling engineering is an important means of resource and environmental exploration, and its research field is extending from the traditional surface to the polar regions, oceans, deep earth, and ocean bottom. Deep drilling will be an important means of deep earth exploration and the only way to obtain real objects deep in the earth. However, in the process of deep drilling, how to keep the wellbore vertical is a big problem. The problem of well deviation will directly restrict the drilling speed and drilling speed. Quality, and even the success or failure of the entire drilling project. [0003] The emergence of automatic vertical drilling tools has brought a major technological breakthrough for deflection prevention and correcti...
