Abstract
The utility model relates to a multiple-member efficiency-enhancing composite perforator used under oil wells, which can effectively prolong the effective acting time of energy and crack maintaining time during the course of perforation. The utility model is composed of a gun head 1, a gun body 4, a perforating bullet 6, a bullet rack 8, a locating plate 9, an incendiary agent plate 14 and fracturing gunpowder 15, wherein, the outside of the gun body 4 has a gel acid sleeve 7, a short sleeve 11 is embedded between the locating plate 9 and the fracturing gunpowder 15, and the short sleeve is filled with proppant 10 and a spacing plate 13. The utility model is characterized in that during the course of perforation, the proppant is sprayed into pore canals and cracks to generate support; the gel acid sleeve can be melted in high temperatures, and the generated air flows and liquid flows are also sprayed into pore canals and cracks; thus, the perforating effect can be enhanced.
Description
The utility model relates to the multi-element synergistic composite perforator that the oil field well needs perforation and pressure break.
Split type, integral type that composite perforator is divided into.Perforator is that petroleum perforation is fixed with totally-enclosed or semiclosed device, ignites by detonating fuse, and penetrates out the device of target zone in the down-hole.High energy gas fracture bomb is a demolition set of loading the produced high energy gas of solid propellant or propellant powder.Split type composite perforator is that perforator is connected by energy converter with high energy gas fracture bomb, ignites high energy gas fracture bomb behind perforation, and produces the perforating and fracturing effect.Its weak point is that the low pressure break effect of capacity usage ratio is undesirable, and benefit is that the explosive payload multiaction time is long.The integral type composite perforator is that the pressure break medicine is placed the perforating bullet firing mount, excites the pressure break medicine to produce the high energy Compressed Gas in perforation, and the high energy Compressed Gas is pressed in the perforation road with jet along prefabricated relief hole, forms to split effect with entrance pressure.Characteristics are: capacity usage ratio height, concentration of energy, the weak point but the few pressure break effect of dose is held time.
More than two kinds of modes all exist energy to utilize effective time short, the crack short defective of holding time.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of multi-element synergistic composite perforator of holding time in Energy Efficient action time and crack that prolongs effectively is provided.
The purpose of this utility model can reach by the following technical programs: have rifle head, detonating fuse, the body of a gun and on the firing mount of blind hole, pressure break medicine, little chip perforating bullet, cleavable and positioning disk, incendiary agent sheet and under the composite perforator that constitutes of pressure break medicine on, wherein the body of a gun has gel acid sheath outward, descending with it to embed short cover between the pressure break medicine in positioning disk in this body of a gun, in this weak point cover spacer and proppant are being housed; The pressure break medicine is contained in the cartridge case.
Above-mentioned incendiary agent sheet is contained in gel acid sheath end opening place.By the multi-element synergistic composite perforator of above forecast scheme configuration, wherein proppant is little coccoid, follows by body of a gun inner chamber blind hole on the body of a gun and enters hole and the crack generation supporting role of injecting; Gel acid sheath is met high temperature and is then melted, and the air-flow of generation and liquid stream produce cleaning action to hole and the crack of injecting; Spacer can be linked up the spatia that the bottom body of a gun enters top under percussion, comprehensive above can realize its purpose.
The utility model is compared with above-mentioned present technology can have following effect: proppant is small granular fluid in the perforator, with igniting in the perforation process, follows by body of a gun inner chamber blind hole on the body of a gun and enters duct and the crack of injecting, and produces supporting role; The outer gel acid sheath of the body of a gun is met high temperature and is then melted, and the air-flow of generation and liquid stream also enter duct and the crack of injecting with ignition, produce and wash away and cleaning action; Spacer is linked up the inner upper and lower clearance channel of the body of a gun igniting under the effect of process surge, prolong in the ignition process Energy Efficient action time and crack and hold time, and has improved the effect of perforation.
Accompanying drawing is the utility model sectional drawing.
To be further described the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing, have rifle head 1, detonating fuse 2, the body of a gun 4 and on the firing mount 8 and composite perforator that positioning disk 9, incendiary agent sheet 14 and pressure break medicine 15 constitute of blind hole 3, pressure break medicine 5, little chip perforating bullet 6, cleavable, outside the body of a gun 4, be with gel acid sheath 7, the body of a gun embeds short cover 11 for 4 li between positioning disk 9 and pressure break medicine 15, this weak point cover is equipped with spacer 13 and proppant 10 for 11 li; Pressure break medicine 15 is contained in 16 li of cartridge cases.
Above-mentioned incendiary agent sheet 14 is contained in gel acid sheath 7 end opening places.The body of a gun 4 is the stairstepping shell, and the bottom is a particle size shell 12, forms uniform blind hole 17 on the shell 12.
