WELL EMERGENCY SEPARATION TOOL FOR USE IN SEPARATING A TUBULAR ELEMENT |
摘要 |
A method of separating a tubular element, comprising providing a tubular element having an inner and an outer surface, a circumference of said outer surface, a longitudinal axis and a first end and a second end; radially surrounding said tubular element with an explosive shaped charge material, wherein said shaped charge explosive material is capable of generating a high-velocity plasma jet in response to an activation signal, and wherein said explosive material comprises an electrically conductive layer; transmitting said activation signal to said explosive material; generating said high-velocity plasma jet; and separating said tubular element into a first portion comprising said first end and a second portion comprising said second end when said high-velocity plasma jet penetrates said outer surface of said tubular element and exits said inner surface of said tubular element. |
