Description
Technical field
The invention belongs to explosive field, be specifically related to a kind of heat-resisting composite explosives and preparation method thereof, use
In petroleum perforation charge powder charge.
Background technology
Along with the continuous rising of China's oil strategic resource international status, to ultradeep well, superelevation hot-well
Exploration demand gets more and more, thus to the energy of the petroleum perforation equipment for oil well perforation and thermostability
Require more and more higher.Heat-resisting composite explosives are the main energy sources of petroleum perforation charge fluidic vectoring thrust, but
Owing to being limited by explosive self-energy and heat resistance, the raising that heat-resisting perforating bullet is worn deep ability has
Limit, need to seek to improve further the approach of perforating bullet powder charge energy.
Current domestic and international heat-resisting perforating bullet powder charge all with heat-resistant explosive HNS, TATB, LLM 105 etc. with few
Amount heat-resistant adhesive is mixed.The external petroleum perforation charge powder charge with LLM 105 explosive as base has no
Report, the paper " HTX: for oil well perforation of Dr.James E.Brooks and Wally Voreck
New explosive formulation ", disclose a kind of by particulate HNS and the TATB mixing medicine of 50:50 form heat-resisting
Perforating bullet powder charge HTX, the shortcoming overcoming HNS or PYX, HTX explodes than HNS in perforating depth
Medicine or PYX explosive increase by 5%～10%.Domestic Xu Wen is new, the paper of Li Bihong etc. is " with LLM 105
The applied research of heat-resisting composite explosives for base ", (" priming system " the 4th phase in 2012, P40) is open
A kind of heat-resisting composite explosives L091, this explosive is by LLM 105 and fluorine-containing polymer binding agent FPM2603
Composition, these composite explosives armor destruction capability under general technical specifications is for averagely to wear deep 223.0mm, high
In the perforating bullet identical bar of powder charge Y971, S992(that the most domestic existing PYX, HNS are main explosive
Deep respectively 190.3mm, 204.0mm is averagely worn under part), improve than S992 average penetration depth
9.3%.Although LLM 105 has the high-energy between HMX and TATB and excellent thermostability,
But only the L091 explosive with LLM 105 as base is under conventional pressing process, and the relative density of powder charge is on the low side
(only 91%), armor destruction capability is difficult to meet current ultradeep well, the exploration demand of superelevation hot-well.
