Use of aluminum in perforating and stimulating a subterranean formation and other engineering applications

A chemical reaction between molten aluminum and an oxygen carrier such as water to do useful work is disclosed, and in particular two chemical methods to obtain aluminum in its molten state. One is to detonate a HE/Al mixture with surplus Al in stoichiometry, and the other is to use an oxidizer/Al mixture with surplus Al in stoichiometry. Additionally, there is a physical method of shocking and heating Al using high temperature reaction products. The produced Al in its liquid form is forced to react with an oxygen carrying liquid (e.g. water), giving off heat and releasing hydrogen gas or other gaseous material. A water solution of some oxygen-rich chemicals (e.g. ammonium nitrate) can be advantageously used in place of water. A shaped charge is also disclosed having a liner that contains aluminum, propelled by a high explosive such as RDX or its mixture with aluminum powder. Some aluminum in its molten state is projected into the perforation and forced to react with water that also enters the perforation, creating another explosion, fracturing the crushed zone of the perforation and initializing cracks. Another shaped charge is shown having a liner of energetic material such as a mixture of aluminum powder and a metal oxide. Upon detonation, the collapsed liner carries kinetic and thermal energy. Also shown are methods to build and to detonate or fire explosive devices in an oxygen carrying liquid (e.g. water) to perforate and stimulate a hydrocarbon-bearing formation.

A multi-component fiber blended facing material is disclosed, whose weight proportion of spinning raw material is (the chaine is same with the weft yarn) 11-20% of tencel, 8-12% of ramee, 8-12% of bamboo fibre, 60-65% of terylene short fiber and 0.5-0.7% of conductive fibre. The invention implementing reasonable collocation and assembly of tencel, terylene, bamboo fibre, ramee and conductive fibre, which not only useds the large brute force and sticking dynam characteristic of terylene, but also full utilizes the superior characteristic and favorable wear behavior of tencel, bamboo fibre and ramee, thereby implementing ascendency complementary and inferior position elimination of various fibres, and meanwhile the conductive fibre has better and longer electrostatic resistance effect in the fibre blended yarns. The facing material has superior characteristics of moisture absorption, ventilating, electrostatic resistance, sticking, sliding, embonpoint hand feeling, good drapability, flokkit and pilling resistance, good model keeping performance, antimicrobial, etc. The invention has reasonable technique, resolve difficult problem of spinning and dyeing, and establish hardness foundation for the amenity and high-grade of the chemical fabrics facing material.

Gas generating process for propulsion and hydrogen production

A gas generating process, which is for the continuous production of energy and hydrogen for rocket and other propulsion and is also for the continuous production of hydrogen, utilizes the reaction of metallic materials, particularly aluminum, with organic materials, particularly hydrocarbons provided as jet fuel, and with water or an oxidizer which is predominantly water. In comparison with related reactions, the reaction produces hot gases containing more hydrogen and the products have a lower temperature for the same specific impulse. The process incorporates organic liquids with metallic powders to produce desirable, lower molecular weight exhaust gas products; and the increased hydrogen is desirable for use with a fuel cell and in connection with propulsion of a super-cavitating underwater device. The process is advantageous in that a metal, in powdered form, and a hydrocarbon liquid may be provided together as a slurry or gel for effective metering. The metallic material may also be provided with the organic material in the form of a binder as used in solid propellants, and the organic material and water may be provided together in the form of a water containing liquid monopropellant. The hydrogen containing product gases from the reaction may be further reacted with suitable oxidizers for production of additional energy or steam. The reaction is particularly useful for underwater vehicles where ambient water is available and the reaction products may be used for propulsion.
