PHL操作手册讲解.doc

Design Overview The Halliburton PHL PERMA-LACH? Packer is a single-bore, hydraulic-set retrievable packer. The packer is designed to be run on production tubing and set by applying internal pressure. The PHL packer features opposing slips above and below the packing elements to withstand pressure differentials above or below. Since the PHL requires no mandrel movement during the setting procedure, the packer may be run in tandem with other packers without the use of telescoping joints. The PHL packer may be run with a number of tubing accessories such as travel joints and overshot tubing seal dividers. Once set, the tubing may be placed in tension, neutral or compression. The PHL Packer is released by straight pull of the tubing string which shears a set of shear screws. When released, the packer opens an internal by-pass to reduce swabbing effects while pulling out of the hole. The PHL packer must be removed and redressed before rerunning. Consider release when running the PHL packer above another single packer. If rotation is required to release the lower packer, install a straight-shear safety joint so that the PHL packer can be retrieved first. Since the packer is hydraulic set, it can be installed with the wellhead in place prior to circulation and setting. 设计概要 哈里伯顿PHL PERMA-LACH?封隔器是单孔，液压坐封可回收式封隔器。此封隔器的工作原理是通过生产管柱下入井中，靠提供油压坐封。PHL封隔器外表在胶筒上下有对相对称的卡瓦，可抵抗封隔器上下的压差。因为PHL封隔器要求在坐封过程中芯轴不动，PHL封隔器可以和其他封隔器串联，在不使用伸缩接头的情况下入井。PHL封隔器可以和一些油管辅助工具一起入井，像伸缩节和打捞筒油管密封分压器。 一旦坐封，油管可能会受到拉力、不受力或挤压力。PHL封隔器靠上提油管串剪切一组解封销钉来解封。解封后，PHL封隔器打开一个内部旁通来降低摩擦力便于提出井口。PHL封隔器二次使用之前必须维修保养。当下入PHL封隔器在另一个封隔器之上时，考虑到回收问题，如果下面的封隔器要求旋转解封，就接一个直切式安全接头以便PHL封隔器能优先解封。由于PHL封隔器是液压坐封，在循环和坐封之前要先安装井口。 Applications The PHL packer is suitable for medium to high-pressure environments.
