    摘要： A nitrate or nitroparaffin-base liquid exlosive composition having a small critical diameter yet which is essentially free of particulate metals such as may render such compositions unduly brisant or susceptible to decomposition, and which is consistent with the safety requirements of geological fracturing, including an inert solid ballistic modifier having a sonic velocity substantially different from that of the explosive material in the composition and an average particle size of less than 10 microns, forming from about 5% to 20% by weight of the composition.

    摘要： A CAP INSENSITIVE LIQUID EXPLOSIVE IS DESCRIBED WHICH IS PARTICULARLY USEFUL FOR FRACTURING A FORMATION CONTAINING A NETWORK OF NARROW FISSURES ADJACENT A WELL BORE IN ORDER TO BRING IN A WELL OR TO INCREASE ITS PRODUCTIVITY, WHICH INCLUDES A NITROPARAFFIN COMPOUND, PREFERABLY NITROMETHANE, CAPABLE OF DISSOLVING SUBSTANTIAL AMOUNTS OF HIGH EXPLOSIVE COMPOUNDS, AND ONE OR MORE OF CERTAIN HIGH EXPLOSIVE COMPOUNDS DISSOLVED THEREIN. THE HIGH EXPLOSIVE COMPOUNDS ARE OF A KIND AND ARE PRESENT IN AN AMOUNT CAPABLE OF RENDERING THE LIQUID EXPLOSIVE SUFFICIENTLY DIAMETER INSENSITIVE TO PERMIT PROPAGATION OF AN EXPLOSION THROUGHOUT A SUBSTANTIAL PORTION OF SUCH NETWORK OF NARROW FISSURES WHEN THE LIQUID EXPLOSIVE IS PLACED THEREIN OR IN SUCH OTHER ENVIRONMENT AS IT IS TO BE USED. PREFERRED HIGH EXPLOSIVES ARE RDX, HMX AND MIXTURES THEREOF. TNT, PETN OR ANY OTHER HIGH EXPLOXIVE ORGANIC NITRO COMPOUND MAY BE INCLUDED IN AN AMOUNT SUFFICIENT TO RENDER THE LIQUID EXPLOSIVE LESS SENSITIVE TO DETONATION, SUCH THAT IT IS NOT CAP DETONABLE, AT THE SAME TIME ENHANCING ITS EXPLOSIVE POWER AND RELIABILITY. FOR CERTAIN APPLICATIONS, AMMONIUM NITRATE MAY BE ADDED TO ACHIEVE DESIRED EXPLOSIVE EFFECTS, AS WELL AS FINELY DIVIDED REACTIVE METAL TO INCREASE THE BRISANCE OF THE EXPLOSIVE. A GELLING AGENT SUCH AS NITTRECELLULOSE IS INCLUDED TO MAINTAIN THE RESULTING UNIFORM DISPERSION FOR LONG PERIODS OF TIME. A METHOD OF PRESSURE-TRANSFERRING A LIQUID EXPLOSIVE INTO THE WELL BORE AND PRESSURING IT BACK INTO THE PRODUCTIVE FORMATION IS DESCRIBED IN WHICH THE EXPLOSIVE IS INJECTED THROUGH A TUBE INTO THE WELL BORE DIRECTTLY ADJACENT THE FORMATION TO BE FRACTURED, THE TUBE HAVING FIRST BEEN CLEARED OF AIR, BY PLACING THE LIQUID EXPLOSIVE IN ONE OR MORE TANKS CONNECTED TO THE INJECTION TUBE AT THE WELL SURFACE AND WHICH ARE SUBJECTED TO AIR PRESSURE TO FORCE THE EXPLOSIVE INTO THE WELL. FURTHER, A WELL FRACTURING METHOD WHICH IS SELF CLEANING, RENDERING UNNECESSARY THE USUAL CLEANING STEP WHICH FOLLOWS FRACTURING, IS DISCLOSED IN WHICH THE WELL BORE IS RESTTRICTED ABOVE THE LEVEL OF THE EXPLOSION AND IS CLOSED ABOVE THE RESTRICTION WITH SANE OR THE LIKE SUCH THAT SUFFICIENT BACK PRESSURE IS MAINTAINED IN THE WELL FOR SATISFACTORY FRACTURING, WHILE THE RESULTANT GASES ARE SUBSEQUENTLY VENTED THROUGH THE RESTTRICTION, BLOWING THE SAND OR OTHER BALLAST AS WELL AS THE RUBBLE GENERATED BY THE EXPLOSION OUT OF THE WELL BORE.

    摘要： A liquid explosive is described which has a small critical diameter, is safe to handle, is capable of use in cold climates and yet is compatible with the higher temperatures commonly present in subterranean formations, which includes a nitroparaffin compound having dissolved therein a nitramine explosive, a ballistic modifier and a detonation aid in such proportions that the critical diameter of the explosive is on the order of one thirty-second inch. Other constituents may also be added for controlling the consistency and ballistic properties as well as the manufacturing and handling properties of the explosive. A thickening or gelling agent is also preferably added to retain the ballistic modifier as well as any other suspended solids in a uniform dispersion. A method of fracturing well formations for enhancing their productivity, using such liquid explosives, is described.

    摘要： A non-toxic and non-corrosive ignition mixture is created by combining the energy system and the pyrotechnic system. The energy system comprises a high explosive from the groups of nitroesters and nitramines and a senzibiliser of the type of tetrazene or derivatives of tetrazoles for its activation. The pyrotechnic system comprises an oxidizing agent from the group of oxides and peroxides of metals, from the group of salts of inorganic oxygen-containing acids, and a fuel which is amorphous boron. The mixture is supplemented with a friction agent which is preferably ground glass. Nitrocellulose, polyvinyl alcohol and acacia gum are used as bonding agents. Mixtures are utilizable in the field of ammunition production for the production of primers, especially for central ignition cartridges.
