摘要： An oil and gas well shaped charge perforator is provided comprising a housing (2), a high explosive (3), and a liner (5) with a further insert liner (6) where the high explosive is positioned between the liner and the housing. In use the high explosive will collapse the liner and insert causing two cutting jets to form. The insert may substantially cover the surface area of the liner or it may over only partially cover the liner, such as the apical portion of the liner or the base portion of liner. Alternatively the insert may be varied in thickness across the surface area of the liner. Typically the thickness of the liner may be between 1 and 10 % of the liner diameter and the thickness of the insert may be between 1 and 200% of the thickness of the liner. The insert may be produced during the manufacture of the liner, but preferably the liner will be a retro fitted item.

摘要： A method for completing an' oil and gas well completion is provided. The perforators (10, 11) may be selected from any known or commonly used perforators and are typically deployed in a perforation gun. The perforators are aligned such that the cutting jets (12, 13) and their associated shockwaves converge towards each other such that their interaction causes increased fracturing of the rock strata. The cutting jets may be also be aligned such that the cutting jets are deliberately caused to collide causing further fracturing of the rock strata. In Ian alternative embodiment of the invention there is provided a shaped charge liner with at least two concave regions, whose geometry is selected such that upon the forced collapse of the liner a plurality of cutting jets is formed which jets are convergent or are capable of colliding in the rock strata.
摘要翻译：提供完成“油气井完井”的方法。穿孔器（10,11）可以选自任何已知或常用的穿孔器，并且通常部署在穿孔枪中。穿孔器对准，使得切割喷嘴（12,13）及其相关联的冲击波朝向彼此会聚，使得它们的相互作用导致岩层的压裂增加。切割喷嘴也可以对准，使得切割喷嘴有意地引起碰撞，导致岩石层的进一步压裂。在本发明的替代实施例中，提供了具有至少两个凹形区域的成形电荷衬里，其几何形状被选择为使得在衬套的强制塌陷时形成多个切割射流，这些射流会聚或能够碰撞在岩层中。
