Geological logging device based on drilling energy spectrum

Abstract

The invention discloses a geological logging device based on a drilling energy spectrum, and belongs to the field of drilling equipment. The geological logging device comprises a multi-shaft drill and a telescopic head connected with the multi-shaft drill, a swing rotating device and a first drill bit are sequentially connected to the lower part of the telescopic head, and the swing rotating device comprises a support module, a rotating shaft, an eccentric shaft, a rotating rod, a first gyroscope and a second gyroscope. The support module comprises a vertical supporting plate, a shaft connecting seat, a first groove seat and a second groove seat are integrally manufactured on the supporting plate from top to bottom, a stratum below the hole opening generates counter-acting force on the first drill bit, the counter-acting force recoils to the first drill bit according to the hardness of the stratum, at the moment, the first drill bit shakes, in the shaking process, the vibration force is transmitted into a sensor, and a map of the rock stratum is constructed through the vibration force.

Description

technical field [0001] The invention belongs to the field of drilling equipment, in particular to a geological recording device based on drilling energy spectrum. Background technique [0002] For many mines with coal and gas outbursts and complex hydrogeological conditions, drilling is the most direct and effective method to ensure safe production, and an important measure to prevent gas accidents and water damage accidents. The requirements for construction inspection equipment and technology such as holes are also constantly improving. [0003] During the drilling construction process, due to some subjective and objective reasons, there are often the following problems: the depth of the drilling hole, the existing methods are basically limited to manually counting the number of drill pipes to determine, or inserting iron wires or plugs into the hole after the hole is formed. It is labor-intensive, time-consuming, and inconvenient to measure with wooden sticks; after the ...

Problems solved by technology

[0003] During the drilling construction process, due to some subjective and objective reasons, there are often the following problems: the depth of the drilling hole, the existing methods are basically limited to manually counting the number of drill pipes to determine, or inserting iron wires or plugs into the hole after the hole is formed. It is labor-intensive, time-consuming, and inconvenient to measure with wooden sticks; after the drilling reaches a certain depth, the axis may be bent, and the drill pipe cannot be drilled straight; it is difficult to judge the rock drillability. Underground operations, and the underground rock formations and other strata structures are complex and cannot be distinguished by naked eyes, which will cause the hole wall to partially collapse under the action of surrounding pressure after the drill pipe is withdrawn and block the drilling hole
