Abstract
An apparatus, method and insulation medium for inserting and insulating a charge medium within a borehole includes a charge tube comprised of an elongate tube having a length and diameter sufficient for containing a desired quantity of a charge medium. A charge medium in a pumpable form is provided for substantially filling the charge tube. An insulation medium in a pumpable form is provided for substantially encapsulating the charge tube and substantially filling an annular space between the charge tube and the borehole for insulating the charge tube from a downhole environment in which the charge tube is to be inserted. A detonator is inserted within the charge medium proximate a distal end of the charge tube and a charge cable extends from the detonator through the charge tube and exits from the charge tube.
Claims42
An apparatus for inserting a charge medium within a borehole, comprising:
- a charge tube comprised of an elongate tube having a length and diameter sufficient for containing a desired quantity of a charge medium, a diameter of the charge tube being less than a diameter of a borehole within which the charge tube is to be inserted;
- a charge medium in a pumpable form for substantially filling the charge tube;
- an insulation medium in a pumpable form for substantially encapsulating the charge tube and substantially filling an annular space between the charge tube and the borehole for insulating the charge tube from a downhole environment in which the charge tube is to be inserted;
- a detonator inserted within the charge medium proximate a distal end of the charge tube and a charge cable extending from the detonator through the charge tube and exiting from the charge tube;
- and
- a plurality of annular supports coupled to the charge tube, each having a diameter that is less than a diameter of the borehole within which the charge tube is to be inserted for creating the annular space between the charge tube and the borehole.
A method for inserting a charge medium within a borehole, comprising:
- drilling a borehole;
- inserting a charge tube comprised of an elongate tube having a length and diameter sufficient for containing a desired quantity of a charge medium, a diameter of the charge tube being less than a diameter of the borehole within which the charge tube is to be inserted;
- dispensing a pumpable insulation medium in the borehole to substantially encapsulate the charge tube and substantially fill an annular space between the charge tube and the borehole for insulating the charge tube from a downhole environment in which the charge tube is to be inserted;
- and
- dispensing a pumpable charge medium in the charge tube to substantially fill the charge tube;
- and
- inserting a detonator within the charge medium proximate a distal end of the charge tube and providing a charge cable extending from the detonator through the charge tube and exiting from the charge tube.

- and
- a detonator inserted within the charge medium proximate a distal end of the charge tube and a charge cable extending from the detonator through the charge tube and exiting from the charge tube;
- and
- a cooling system comprising cooling tubing extending a substantial length of the charge tube and disposed proximate thereto and a coolant disposed within the cooling tubing, the cooling tubing coupled to a pump for circulating the coolant through the cooling tubing.
An apparatus for inserting a charge medium within a borehole, comprising:
- a charge tube comprised of an elongate tube having a length and diameter sufficient for containing a desired quantity of a charge medium, a diameter of the charge tube being less than a diameter of a borehole within which the charge tube is to be inserted;
- a charge medium in a pumpable form for substantially filling the charge tube;
- an insulation medium, comprised of a clay, a liquefying component, an adsorption component, and a neutralizing component, in a pumpable form for substantially encapsulating the charge tube and substantially filling an annular space between the charge tube and the borehole for insulating the charge tube from a downhole environment in which the charge tube is to be inserted;
- and
- a detonator inserted within the charge medium proximate a distal end of the charge tube and a charge cable extending from the detonator through the charge tube and exiting from the charge tube.
