摘要： A tubing conveyed perforating apparatus is shown which includes a tubular firing section which carries a plurality of explosive charges. The explosive charges are initially aligned with regions of reduced wall area provided in a tubular firing section which initially surrounds the charges. A piston sleeve is mounted on the exterior of the firing section. The piston sleeve has a plurality of apertures which are initially aligned with the regions of reduced wall area in the tubular firing section and thus with the explosive charges. Detonation of the charges causes the piston sleeve to shift so that the piston sleeve apertures are out of alignment with openings formed in the tubular firing section by the detonation of the charges, thereby trapping any resulting debris within the interior of the tubular firing section. Firing of the explosive charges opens upper and lower circulating ports so that sand or other debris can be reverse circulated up the interior of the well string to the well surface. A piston actuated retrieving head can be utilized to engage and retrieve a sealing plug from a sump packer within the well bore.
摘要翻译：示出了输送穿孔装置的管道，其包括携带多个爆炸装药的管状燃烧部分。炸药最初与最初包围电荷的管状点火部分中提供的壁面积减小的区域对齐。活塞套筒安装在击发部分的外部。活塞套筒具有多个孔，它们最初与管状点火部分中的壁面积减小的区域对准，因此与爆炸装置对齐。电荷的引爆导致活塞套筒移动，使得活塞套筒孔与通过电荷引爆形成在管状点火部分中的开口不对齐，从而将任何产生的碎屑捕获在管状点火部分内部。燃烧炸药打开上下循环口，使得沙子或其他碎屑可以从井筒内部向井筒表面反向循环。活塞致动的回收头可以用于从井筒内的贮槽封隔器接合和回收密封塞。

摘要： Downhole drill pipe cutting is achieved by a free-falling sub carrying a shaped charge cutter and an ablative fluid cutter. Upon seating on a drill string flow bore orifice, fluid pressure is raised to detonate the shaped charge cutter. In the event the shaped charge cutter fails, pressure is further raised to effect a cut by fluid ablation.

摘要： A string of drill pipe, for example, is assembled with a severing sub in anticipation of a possible need to cut the string at some point in the operation. The severing sub includes a thin wall tube that links opposite end tool joint bosses. The tin wall tube is easily cut by a shaped charge cutter. Rotary drive torque is transmitted between the sub tool join bosses by a concentric external torque tube having a torque transmitting assembly at each boss. The torque tube connection to the upper boss has an inseparable circumferential shoulder engagement with the boss. The lower boss engagement of the torque tube is axially separable. When the thin wall tube is cut, the upper boss and torque tube is withdrawn from the well with the upper pipe string.

摘要： A system for positioning a downhole tool along a pipe string, the system having a series of seating subs inserted along the length of the pipe string wherein each seating sub has a seating aperture disposed around its internal periphery so as to form a bore plug seat of smaller diameter than the diameter of the pipe. The seating apertures are given distinctive diameters that are consecutively arranged along the pipe string length so that the aperture diameters decrease with increasing depth. A drop assembly having an aperture plugging diameter selected to pressure seal a selected aperture includes a bore pressure activated by-pass valve and firing head.

摘要： A free falling drop sub carries an explosive tool such as a shaped charge pipe cutter or well perforator. The drop sub includes an aperture plugging element to isolate an upper pipe string from a lower pipe string. An upper pipe string fluid pressure actuated valve element retained by shear pins is released to admit the upper string pressure against a pressure displaced firing pin. Displacement of the firing pin initiates detonation of the explosive tool.

摘要： A shaped charge carrier tool is provided that has particular utility for perforating well casing as a preparation for cement placement. A plurality, four or more elongated shaped charge carrier ribs having a high bending modulus are secured for radially expanded displacement around a central framing tube or rod. Radius rods link the ends of the carrier ribs to top and bottom hinge carriers. The hinge carriers encircle the framing tube and are free for axial translation along the framing tube. Articulating hinges connect the radius rods to the carrier ribs and to the hinge carriers. Opposed compressed coil springs provide a resilient bias on the hinge carriers to translate the carrier ribs radially outward against the interior surface of a well casing as the tool passes from a riser tube into a larger inside diameter well casing.

摘要： For a free falling well tool sub having one or more pipe bore centering cages, a collapsible material cone secured inside of the centering cage half length with the cone base opening in the downhole direction restricts the rate of pipe bore fluid flow past the cone and thereby restricts the descent rate of the tool. The rate of descent may be regulated with fluid flow by-pass apertures in the sub. A collapsible material cone in a bore centering cage having a base opening in the up-hole direction may be used as piston to drive the tool sub along horizontal segments of a deviated well bore. Both cones may be used separately or together.

摘要： Detonation of a perforating gun is initiated by engagement of the lower distal end of the gun assembly against a bottom hole bore plug. A fluid pressure actuated firing head is initiated by well fluid that is pressurized by a free piston having an integral rod projecting from the distal end of the gun assembly. The piston is displaced against a closed fluid volume when the projecting rod engages the bore plug.
