Descripción del proyecto
Una tecnología mejorada para la extracción geotérmica
La energía geotérmica es un recurso respetuoso con el medio ambiente que podría satisfacer las futuras demandas de calefacción, refrigeración y electricidad. Sin embargo, aún no se ha explotado lo suficiente debido a que los métodos de perforación suelen ser caros y consumen mucho tiempo. El proyecto Geo-Drill, financiado con fondos europeos, tiene como objetivo desarrollar equipos de extracción avanzados a fin de reducir costes y aumentar el ritmo de la penetración en la extracción geotérmica. Esta innovadora tecnología de perforación agrupará martillos de lodo controlados por amplificadores fluídicos biestables, sensores impresos en 3D y cables para mejorar la monitorización y revestimientos de grafeno para mejorar la resistencia y duración de la perforación. La reducción de los costes de perforación en hasta un 60 % fomentará la inversión y hará que la energía geotérmica sea más accesible.
Objetivo
Geothermal is the most under-utilized of renewable sources due to high investment costs and long development cycle. A big part (53%) of the cost is in drilling and it is time-dependent. Geo-Drill aims to reduce drilling cost with increased ROP and reduced tripping with improved tools lives. Geo-Drill is proposing drilling technology incorporating bi-stable fluidic amplifier driven mud hammer, low cost 3D printed sensors & cables, drill monitoring system, Graphene based materials and coatings. Geo-Drill fluidic amplifier driven hammer is less sensitive to issues with mud and tolerances, less impact of erosion on hammer efficiency and it continues to operate with varying mud quality in efficient manner. It is also less affected by the environmental influences such as shocks, vibrations, accelerations, temperature and high pressures. Low cost and robust 3D-printed sensors & cables along the surface of the whole length of the drill string provides real-time high bandwidth data during drilling; e.g. estimation of rock formation hardness, mud flow speed, density, temp, etc. Flow assurance simulations combined with sensor readings and knowledge-based system will assist in optimizing drilling parameters and cuttings transport performance and safety conditions. Graphene's ability to tune the particular form lends itself uniquely as a component in a wide variety of matrices for coating developments with enhanced adhesion and dispersion properties and improved resistance to abrasion, erosion, corrosion and impact. Placing few mm hard-strength materials on drill bit, drill stabilizer through diffusion bonding improves their wear resistance and improve the lifetime. Geo-Drill's hammers improved efficiency and lifetime, drill parameter optimisation and CTP via sensors, reduced time in replacing tools with improved lifetime work together to improve ROP & lifetime resulting in reduced drilling time. Thereby, Geo-Drill will reduce drilling cost by 29-60%.
