TUBO EXTERNO: Transmite peso, rotacin y elfludo de perforacin a la corona

JUNTA DE SEGURIDAD: Permite extraer el tubo

interno en caso de pega.

ESTABILIZADOR : Centraliza el barril en el pozo.

CORONA: Corta la formacin.

JUNTA GIRATORIA: Aisla el tubo interno de la

rotacin a travs del balero.

TUBO INTERNO: Aloja el ncleo una vez cortado.

RETENEDOR NUCLEO: Corta el ncleo del fondo ylo retiene dentro del tubo interno.

Cambios litolgicos de lutita a

limolita

Por fracturamiento de laformacin

Debido a los cambios litolgicos..

Cuando existe el cambio litolgico se pierde lacontinuidad del ncleo, entonces el ncleo que esta

entrando tiene que empujar al que esta arriba y si

este es una seccin muy pesada igualmente se

atasca.

System passes through standard drill collar bore with standard conne

System operates with standard drill string and drilling services no

customization is required.

Clear positive pressure signal indicates :

Inner tube landing

Core jamming

Inner barrel is stabilized at four separate points

Flow rate capacity is much higher than in conventional coring applicat

Inner barrel permits recovery of full-length 32 ft core sections up to 9

Quick retrieval rate and elimination of pipe tripping operations result i

significant rig time saving.
