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.
