摘要： A shaped charge (10) and a method of using such to provide for large and effective perforations in oil bearing sandy formations while causing minimal disturbance to the formation porosity is described. This shaped charge uses a low-density liner (24) having a filler material that is enclosed by outer walls made, preferably, of plastic or polyester. The filler material is preferably a powdered metal or a granulated substance, which is left largely unconsolidated. The preferred filler material is aluminum powder, or aluminum particles, that are coated with an oxidizing substance, such as TEFLON®, permitting a secondary detonation reaction inside the formation following jet penetration. The filled liner is also provided with a metal cap to aid penetration of the gun scallops, the surrounding borehole casing and the cement sheath.
摘要翻译：描述了一种成形装料（10）以及使用这种方法来在含油砂层中提供大的有效的穿孔，同时对地层孔隙度造成最小的干扰。该成形装料使用具有由优选由塑料或聚酯制成的外壁包围的填充材料的低密度衬里（24）。填充材料优选为粉末状金属或粒状物质，其在很大程度上未被固化。优选的填充材料是铝粉末或铝颗粒，其被涂覆有诸如TEFLON的氧化物质，允许喷射穿透之后的地层内的次级爆炸反应。填充衬里还设置有金属盖，以帮助枪扇贝，周围钻孔套管和水泥护套的穿透。

摘要： A shaped charge and a method of using such to provide for large and effective perforations in oil bearing sandy formations while causing minimal disturbance to the formation porosity is described. This shaped charge uses a low-density liner having a filler material that is enclosed by outer walls made, preferably, of plastic or polyester. The filler material is preferably a powdered metal or a granulated substance, which is left largely unconsolidated. The preferred filler material is aluminum powder, or aluminum particles, that are coated with an oxidizing substance, such as TEFLON®, permitting a secondary detonation reaction inside the formation following jet penetration. The filled liner is also provided with a metal cap to aid penetration of the gun scallops, the surrounding borehole casing and the cement sheath. The metal cap forms the leading portion of the jet, during detonation. The remaining portion of the jet is formed from the low-density filler material, thereby resulting in a more particulated jet. The jet results in less compression around the perforation tunnel and less skin damage to the proximal end of the perforation tunnel.
摘要翻译：描述了一种成形装料和使用这种方法在含油砂层中提供大的和有效的穿孔，同时对地层孔隙度造成最小的干扰。该成形装料使用具有由优选由塑料或聚酯制成的外壁包围的填料的低密度衬里。填充材料优选为粉末状金属或粒状物质，其在很大程度上未被固化。优选的填充材料是铝粉末或铝颗粒，其涂覆有氧化物质，例如TEFLON，其允许喷射穿透之后的地层内的次级爆炸反应。填充衬里还设置有金属盖，以帮助枪扇贝，周围钻孔套管和水泥护套的穿透。在爆炸期间，金属盖形成射流的引导部分。射流的剩余部分由低密度填料形成，从而导致更多的雾化射流。射流导致穿孔隧道周围的压缩较少，对穿孔隧道近端的皮肤损伤较少。
