Sistemas excéntricos de perforación con tubería de revestimiento sobrecargada

Los sistemas excéntricos de perforación de revestimientos son la solución más económica. Gracias a su ingenioso diseño, el ala de escariado de la broca es recuperable, lo que permite reutilizarla para el siguiente orificio. Esto no sólo reduce significativamente los costes de sustitución del equipo, sino que también minimiza el tiempo de inactividad, mejorando la eficacia general de la perforación y convirtiéndola en una opción rentable para diversos proyectos.

Ame Drill Eccentric Overburden Casing Drilling Systems

Casing drilling, or casing while drilling (CWD) process, is a concept that combining two time-consuming processes, drilling and casing together, performing them at the same time. During the CWD process, powered by DTH hammer, a central piloting bit drives a ring bit to drill a hole wide enough for a casing tube to slide down, drilling and casing processes are therefore performed at the same time.

Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole. This is particularly design for shallow holes, as is often the case in water well drilling, geothermal wells and for shallow micro-piling work. Odex is ideal for short holes in consolidated overburden. The component of Eccentric system consists of Pilot bits, Reamer bits, Guide device and casing shoe.

When drilling, the reamer bit will rotate out to enlarge the hole which enough for the casing tube slide down behind the reamer. When reached required depth, the drill pipe will drill to the reverse direction and the reamer bit will retract, it is allowing the whole drilling system to pass through the casing.

Features of Eccentric Overburden Casing Drilling Systems

• Complete types of drilling tools suitable for casing tubes with various diameters;

• Good stability and reliability granted by premium alloy steel material and fine CNC manufacturing process;

• Cost-effectiveness realized by mass production.

Applications of Eccentric Overburden Casing Drilling Systems

Eccentric overburden casing drilling systems find diverse applications across multiple industries. In mining and quarrying, these systems ensure stability by preventing cave-ins when extracting valuable resources. For water well and geothermal well drilling, they isolate unstable strata, safeguarding the wellbore and enhancing the efficiency of fluid extraction or heat exchange. In foundation piling, they enable precise installation of piles in challenging soil conditions, providing a robust base for construction projects. Their versatility makes them indispensable in ensuring the success of various drilling and construction endeavors.
