摘要： A shaped charge assembly (10) comprises a housing (20), first shaped charge (24), a wave shaping relay charge (44) and a second shaped charge (30) located in the housing. The assembly (10) is configured such that a first active element formed by initiation of the first shaped charge (24) causes detonation of the wave shaping relay charge (44), which in turn causes initiation of the second shaped charge (30) to form a second active element. The first active element moves beyond a second end (25) of the housing to cause damage of a first kind to an external target and the second active element also moves beyond the second end to cause damage of a second kind to the target.

摘要： A limited entry perforating phased gun system and method for accurate perforation in a deviated/horizontal wellbore is disclosed. The system/method includes a gun string assembly (GSA' ) deployed in a wellbore with shaped charge clusters. The charges are spaced and angled such that, when perforated they intersect at a preferred fracturing plane. Upon fracturing, the fractures initiate at least principal stress location in a preferred fracturing plane perpendicular to the wellbore from an upward and downward location of the wellbore. Thereafter, the fractures connect radially about the wellbore in the preferred fracturing plane. The fracture treatment in the preferred fracturing plane creates minimal tortuosity paths for longer extension of fractures that enables efficient oil and gas flow rates during production.
摘要翻译：公开了一种有限入射穿孔相位枪系统和在偏斜/水平井筒中精确穿孔的方法。系统/方法包括部署在具有成形电荷簇的井眼中的枪串组件（GSA'）。电荷被间隔开并成角度，使得当它们穿孔时，它们在优选的压裂平面相交。在断裂时，裂缝从井眼的向上和向下的位置开始至少在垂直于井筒的优选压裂平面中的主应力位置。此后，裂缝在优选的压裂平面内围绕井筒径向连接。在优选的压裂平面中的断裂处理为裂缝的更长延伸创造了最小的弯曲路径，从而在生产过程中实现了有效的油气流速。

摘要： A method and apparatus to protect explosive components (704 or 804) used in various tools, such as tools for use in wellbores, includes a component (704 or 804) with an adsorptive material (702 or 802). Example tools include perforating gun strings (110) that include shaped charges (700 or 800), detonating cords (220), and booster explosives (114). Other tools may include surface tools containing explosive components. In these tools, a build up of corrosive gases or liquids may occur, which may cause damage to the explosive components (704 or 804). As a result, the structural integrity or reliability and thermal stability may be weakened or reduced. To reduce the amount of build up of corrosive gases or liquids, an adsorptive material (702 or 802) is placed inside tools in the proximity of explosive components (704 or 804).
