“…On the one hand, such devices can stabilize the drilling rig and effectively provide shock absorption and lateral support; on the other hand, they can be combined with the programmable controller to achieve smooth hydraulic transmission, which can greatly improve the efficiency of drilling cataloguing [8][9][10][11]. Some scholars can establish dynamic links with a large amount of physical logging data through the existing spatial geographic information system data, greatly improving the efficiency of data classification [12,13]. In addition, some borehole cataloguing methods based on mobile technology enable various borehole data to be entered and managed in a unified manner, which improves cataloguing efficiency [14][15][16].…”

Borehole cataloguing is an important task in geological drilling. Traditional manual cataloguing provides the stratification of underground boreholes based on changes in core lithology. This paper proposes a novel borehole cataloguing method using a drilling process monitoring (DPM) system. This DPM cataloguing method stratifies a borehole according to the drilling speed through the rock. A 102 m borehole was drilled and cored in Baota district, Yan’an city, Shaanxi Province, China. The rock-breaking response parameters of the drill bit displacement, drill rod rotation speed and inlet pipe and outlet pipe oil pressures were monitored throughout the drilling process, and the drilling depth-penetration rate curve during the net drilling process was obtained. The changes in drilling speed show that the DPM cataloguing can identify the depths of the layer interfaces of the borehole and describe the stratification. The interface depth values obtained by DPM have little difference from the interface depth values obtained by manual cataloguing, and the errors are between −0.04% and 4.29%. From the DPM stratification results, the engineering quality evaluation of the rock mass can be realized without coring. DPM is fast, convenient, accurate, can greatly improve the efficiency of existing catalogues, and can be applied to scientific research in any underground space. DPM is a measurement-while-drilling technology. According to DPM data, the operating state of a drilling rig and the parameter changes while drilling can be obtained in situ and in real time throughout the drilling process.

“…Estas reconstrucciones están basadas, por lo general, en cartografías geológicas, observaciones en afloramientos, sondeos de reconocimiento, mallas de cor-tes geológicos y secciones geofísicas, entre otros datos. La provisión por tanto de datos en cantidad y calidad es indispensable para nutrir a los modelos, por lo que en numerosos casos su expansión ha transcurrido en paralelo a la relevancia que han adquirido las bases de datos geológicos y geotécnicos digitales (Veeger et al, 2004).…”

En relación a las investigaciones sobre geología urbana en Asturias (NO de España) se presenta el primer modelo tridimensional basado en capas acerca de la configuración geológica del centro de Oviedo. El modelo obtenido está fundamentado en los datos sobre el subsuelo proporcionados por casi un millar de puntos de reconocimiento georreferenciados, incluyendo más de 500 sondeos mecánicos, cubriendo un área de aproximadamente 3 km 2. Esta información, almacenada en una base de datos geotécnicos, fue gestionada empleando un Sistema de Información Geográfica. Tras preparar un Modelo Digital de Elevaciones a modo de referencia altitudinal, han sido generadas diferentes superficies ráster por medio de un interpolador determinístico y álgebra de mapas, representando los contactos entre las unidades geológicas. Esto ha permitido revisar y actualizar la cartografía geológica superficial; investigar la geometría de las unidades, principalmente sus espesores; y deducir el trazado de potenciales fallas que cruzan el subsuelo urbano. Todo ello ha sido integrado en un entorno virtual 3D complementado en superficie mediante la recreación de diversos elementos del entramado urbano.
