Problems solved by technology

[0003] At present, there is no widely used small-scale intelligent tunneling machine. For the complex problems of drilling downhole, it is mainly based on the changes of pump pressure, suspension weight, drilling fluid inlet and outlet flow, mechanical penetration rate, and the resistance change when the drilling tool rotates up and down. Analyzing and judging complex problems in downhole drilling

Abstract

The invention relates to a bionic gopher intelligent excavating system. The system comprises a drill bit, a shell, a driving mechanism, a telescopic assembly and an adjustable support foot. The drillbit is arranged in the front end of the shell, the driving mechanism is arranged in the shell, and an output shaft of the driving mechanism is connected with the drill bit. The telescopic assembly isarranged in the shell and the telescopic end of the telescopic assembly extends from the back end of the shell to the outside of the shell and is rotationally connected with the adjustable support foot. The system has the advantages that the bionic gopher intelligent excavating system realizes the mechanical simplification of the excavating function of a gopher, makes a whole system structure simple and small, fully considers the coordination of the adjustable support foot and the drill bit which are used as surrounding rocks, and through the expansion of the system itself and alternative movement, the whole system is moved forward, so that the excavation efficiency is improved, the hard bottom layer is adapted, the risk of drilling accidents is reduced, the stratum is quickly went through, the geological data is explored, the safety and accuracy of the drilling construction are improved.

Description

technical field [0001] The invention relates to a bionic hamster intelligent excavation system. Background technique [0002] The oil and gas drilling project is a multi-process, three-dimensional cross-system project, and it is also a highly concealed underground project. The unknown and complex geological conditions hide many unsafe factors. If the underground geological conditions are not obtained by downhole detection, the proposed Drilling geological design, practical prevention, prone to various engineering accidents, resulting in huge losses of life and property. At the same time, the convenient and quick method of direct excavation and detection before drilling can quickly and clearly find out the underground substratum structure and oil and gas conditions, which is more conducive to the design of drilling and oil production construction plans and the accurate drilling of drill bits to target areas and resources. The target layer plays a decisive role in key objecti...
