摘要： A latching device to be used with a cement squeeze packer and a stinger is disclosed. The latching device enables an operator at the surface of an oil or gas well to open and close the squeeze packer valve without the risk of pulling the stinger out of the packer. The latch assembly is installed on the stinger assembly and is provided with a plurality of radially flexible fingers that engage the uphole end of the packer mandrel. Preferably, a series of ribs on both the latch and the uphole end of the mandrel are engaged when the stinger assembly descends into the hole and the stinger enters the packer. These ribs prevent the stinger from coming out of the packer until a predetermined tensile force is applied.

摘要： A hydraulic setting tool for packers capable of mechanically setting the packer and opening a valve in the packer in one trip. The tool comprises an outer sleeve and an inner mandrel coaxially disposed within the outer sleeve and adapted to move axially relative to the outer sleeve. The tool further comprises three locking mechnisms that unlock under different fluid pressure loads. Two of the locking mechanisms lock the inner mandrel to the outer sleeve in a run-in position. Once a sufficient fluid pressure has been reached to unlock both of these locking mechanisms, the inner mandrel moves upward relative to the outer sleeve to set the packer. A spring forces the inner mandrel into a third position relative to the outer sleeve, which is maintained by the third locking mechanism. This third position is used to open the packer valve.
摘要翻译：一种用于封隔器的液压固定工具，其能够机械地设置封隔器并在一次行程中打开封隔器中的阀。该工具包括外套筒和同心地设置在外套筒内并适于相对于外套筒轴向移动的内心轴。该工具还包括在不同流体压力负载下解锁的三个锁定机构。两个锁定机构将内部心轴锁定到外部套筒中。一旦已经达到足够的流体压力来解锁这两个锁定机构，则内心轴相对于外套筒向上移动以设置封隔器。弹簧迫使内心轴相对于由第三锁定机构保持的外套筒的第三位置。该第三个位置用于打开封隔器阀。
