Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] like figure 1 As shown, the drilling induction recognition system of the formation geological interface instrument of the present invention includes a data sensing unit, a data acquisition unit and a data analysis unit;

[0037] The sensing unit includes a pressure sensor S1, which is used to monitor the horizontal forward or backward movement of the drilling rig, the forward or backward movement of the drill bit and drill pipe, the flushing water / hydraulic pressure, and other liquid or gas pressures when dynamic loads are generated. For hydraulic rotary drilling rigs, the dynamic load includes: (1) the pressure of the drilling rig moving forward or backward along the horizontal guide rail; (2) the pressure of the drilling tool moving in or out along the drill frame, that is, the axial pressure and the regulating pressure; (3) Fluid pressure.

Abstract

The invention relates to a stratum geology interface instrument drilling induction recognition system, comprising a data induction unit, a data collection unit and a data analysis unit; the monitoring of the working parameters of a drilling machine and the monitoring of drilling parameters of a drilling bit are effectively combined by the system, on one hand, by monitoring the working pressure, temperature, flushing liquid and fuel oil of the drilling machine, the real-time monitoring, fault diagnosis and control management to the working state, oil consumption and heating state and the like of the drilling machine can be realized; on the other hand, by monitoring the drilling axial stress and vibration of the drilling bit, the stress of the drilling bit is analyzed in the drilling process, and stratal mechanical judgment and classification can be carried out to the penetrated geology material according to the drilling force without sampling, soil test and indoor rock-soil mechanical property test, and 2 / 3 of sampling and drilling time can be saved; the installation is easy, the operation is simple and the recognition precision is high.

Description

technical field [0001] The invention belongs to the technical field of geology and geotechnical engineering, and particularly relates to a drilling induction recognition system for stratum geological interface instruments, which can be used for stratum interfaces, fracture structures, fractured zones, weak aquifers, karst cavities, etc. in geology and geotechnical engineering. Identification of stratum structure dissimilation characteristics such as goaf and filling cementation state. Background technique [0002] At present, in geological and geotechnical engineering surveys, the commonly used interface identification method is drilling, and its identification technology methods such as static penetration test (cone penetration test: CPT), cone dynamic penetration test (dynamic penetration test: DPT) , standard penetration test (standard penetration test: SPT) and rock drillability test (rockdrillability test: RDT), etc. During the drilling process, in order to obtain the ...
