摘要： A propellant assembly for fracturing a formation around a well includes a propellant and a detonating cord wrapped around the propellant, the detonating cord to ignite the propellant upon detonation of the detonating cord. Alternatively, the propellant can include a substantially central axial bore, with the propellant having a plurality of axial slots extending radially outwardly from the axial bore toward the outer surface of the propellant. A detonating cord is arranged within the axial bore of the propellant.

摘要： A loading tube for use in a perforating gun is disclosed which eliminates the necessity for utilization of plastic jackets to restrain shaped charges. The loading tube comprises a first tubular member and an engagement structure in the first tubular member in which the primer ends of the shaped charges may be installed. These engagement structures may be a center plate or inner tubular members. In each of the disclosed embodiments, a detonating cord connects the primer ends of the shaped charges which are installed in the loading tube.

摘要： An adapter is provided for holding and mounting a shaped charge having a non-standard size into a standard loading tube of a hollow carrier gun. The adapter may include a housing assembly having an interior bore to hold a relatively small shaped charge and an exterior surface sized for mounting in a standard loading tube via a standard jacket. Alternatively, the adapter may include an improved jacket having interior ribs for supporting a relatively small shaped charge and an exterior surface for mounting the shaped charge in a standard loading tube of a relatively large gun.
摘要翻译：提供适配器，用于将具有非标准尺寸的成形装料保持并安装到空心载体枪的标准加载管中。适配器可以包括壳体组件，其具有内孔以保持相对较小的成形电荷，以及外表面，其尺寸适于通过标准护套安装在标准加载管中。或者，适配器可以包括改进的护套，其具有用于支撑相对小的成形电荷的内部肋和用于将成形电荷安装在相对较大的枪的标准加载管中的外表面。

摘要： Weight spacer apparatus is disclosed which comprises a carrier which is tubular in shape and a spacer tube which is also tubular in shape for insertion into the carrier. The weight spacer apparatus according to the present invention further comprises a plurality of weight bars which may be inserted into the spacer tube after the spacer tube is inserted into the carrier and which are also removable from the spacer tube. In one embodiment, a weight tray is inserted into the spacer tube for receiving the weight bars, and the weight tray may be fabricated from half-round tubing with a welded plate to cover the diametric opening. In another embodiment, a center plate is attached inside the spacer tube along the length of the spacer tube to divide the spacer tube into first and second compartments. The first compartment comprises a weight tray for receiving the plurality of weight bars, and the portion of the spacer tube opposite the first compartment has openings formed in it to receive shaped charges.
摘要翻译：公开了一种重量间隔装置，其包括管状的载体和间隔管，其也是管状的用于插入载体的形状。根据本发明的重量间隔器装置还包括多个重物棒，其可以在间隔管插入载体中之后插入间隔管中，并且也可从间隔管移除。在一个实施例中，将重物托盘插入间隔管中以接收重物杆，并且重物托盘可以由具有焊接板的半圆管制成以覆盖直径开口。在另一个实施例中，中心板沿间隔管的长度附接在间隔管的内部，以将间隔管分成第一和第二隔室。第一隔室包括用于容纳多个配重杆的配重托盘，并且与第一隔室相对的间隔管的部分具有形成在其中的开口以容纳成形的电荷。
