Abstract

UNA BROCA DE TALADRO PARA TALADRAR A TRAVES DE FORMACIONES VISCOSAS O HUMEDAS, TALES COMO GREDA O MARGA, ABARCA UNA DIVERSIDAD DE VIAS DE AGUA 4 PARA TRANSPORTAR EL FLUIDO TALADRADO Y LAS PARTICULAS DE ROCA A LA TROCHA DE LA BROCA. ESTAS VIAS DE AGUA TIENEN EN LA DIRECCION CORRIENTE ABAJO AREAS A DE SECCION O CORTE TRANSVERSAL QUE AUMENTAN GRADUALMENTE, SIENDO EL AUMENTO DEL TAMAÑO DE LAS AREAS CITADAS A LO LARGO DE LA LONGITUD DE UNA CORRIENTE DE AGUA AL MENOS PROPORCIONAL SUSTANCIALMENTE AL RADIO R CUADRADO DE LAS MISMAS DESDE EL EJE CENTRAL 10. DE ESTA MANERA LA VELOCIDAD DE LAS PARTICULAS DE ROCA PERMANECE IGUAL O DISMINUYE EN LA DIRECCION CORRIENTE ABAJO EN LAS CORRIENTES DE AGUA, DE FORMA QUE EL RIESGO DE ACUMULACION DE DETRITUS DE ROCAS Y COMPACTACION SE REDUCE.
