摘要： A well packing system and method for operating a well packing system wherein an isolation string assembly has a lower circulation valve with lateral flow ports that are operated to an open position without the use of shifters on a wash pipe. The isolation string assembly is incorporated into a well packing assembly within a wellbore and includes an upper sleeve tool that provides selective production of fluids through the frac pack assembly. In addition, the isolation string includes a lower circulation valve having a sliding sleeve that is shiftable from an open position to a closed position upon receipt of a suitable pressure differential. This configuration is particularly valuable for permitting monitoring of pressure or other conditions in the annulus of the wellbore portion being packed during packing operations. Further, the lower circulation valve tool can be used to selectively allow fluid returns during the packing operation.

摘要： The lock allows two members in a downhole tool to be temporarily held together. In an application where mandrel movement is dictated by pressure cycling in combination with a J-slot mechanism, such as in a downhole valve, the mandrel is releaseably retained to an adjacent connector against mechanical impacts. The mandrel features an extended collet that moves relatively to a floating sleeve during pressure cycles. At some point the collet heads rise to an elevated groove that causes them to contact a no-go shoulder for locking. The lock is defeated be removing the collet heads from the elevated groove for normal tool operation.
摘要翻译：该锁允许井下工具中的两个构件暂时保持在一起。在诸如在井下阀中的J型槽机构结合压力循环来规定心轴运动的应用中，心轴可释放地保持在相邻的连接器上以防止机械冲击。心轴具有在压力循环期间相对于浮动套筒移动的延伸夹头。在某些时候，夹头头上升到一个升高的槽，使它们接触一个不脱离的肩膀进行锁定。由于正常的工具操作，锁被从升高的槽中取出夹头。

摘要： A system for enhancing oil production and reducing contamination thereof by such things as water breakthrough in unconsolidated horizontal wells comprises gravel packing, zonal isolation and selective flow control in combination. The significant control provided by the system enables the well operator to create a uniform pressure drop form heel to toe of the horizontal well and avoid commonly experienced water coning and early breakthrough at the heel of the horizontal borehole.
