Abstract: A two-way repeatable flushing device, comprising a flushing member (20) for flushing upwards into the annular space between drill pipe and bore hole wall (or lining pipe). The flushing is ensured by means of a remotely controlled valve and a balanced pressure control by associated valve parts (21, 23) by means of pressure liquid. Thereby there can be ensured a controlled distribution of the flow downwards and upwards respectively, and the hydraulic conditions can thereby be improved by hole cleaning during the drilling operation itself. The solution is particularly of interest for use in particularly complicated, long-range wells having significant paths in a horizontal direction. For these types of wells it has been very difficult traditionally to achieve a satisfactory hole cleaning by means of the flow of liquid in the annular space. The flushing member will ensure a satisfactory hole cleaning as a consequence of improved hydraulic conditions in the annular space. With this a significant profit can be obtained related to both economy, quality and reliability.

Abstract translation: 双向可重复冲洗装置，包括用于向上冲入钻管和钻孔壁（或衬管）之间的环形空间的冲洗构件（20）。 通过远程控制的阀门和通过压力液体的相关阀部件（21,23）的平衡压力控制来确保冲洗。 因此，可以确保流量向下和向上的受控分配，并且因此可以通过在钻井操作本身期间的孔清洁来改善液压条件。 该解决方案特别适用于在水平方向上具有显着路径的特别复杂的长程井中。 对于这些类型的井，传统上通过液体在环形空间中的流动来实现令人满意的孔清洁是非常困难的。 由于环形空间中的液压条件改善，冲洗构件将确保良好的孔清洁。 这样可以获得与经济，质量和可靠性有关的巨大利润。

Abstract: A gravel-packed pipeline is formed by inserting a liner pipe (22) having a porous pipe (16) contained therein. A conveyor pipe (30) is attached to the liner pipe for conveying filtering material (18) such as gravel. After positioning the liner pipe, the end of the porous pipe is pushed out and anchored (28). The liner is removed while the filtering material is conveyed to the hole (20).

Abstract: A conduit (3) can be cleaned by directing jets (10-14, 25) of abrasive mixture from a pressurised supply at its internal wall from a plurality of nozzles (7, 13, 16) which have no tangential component about the conduit axis. Nozzles preferably include two types, one type (7) which is inclined in one direction to the axis and another type (13) which is inclined in the opposite direction to the axis. When the conduit (3) has an open end, the nozzles (7) directed away from that end are preferably closer to the end than those (13) directed towards it. The density of abrasive mixture supplied by the different types of nozzles is arranged to be different by swirling the mixture and supplying different types of nozzles from different radii in the swirl output chamber (6).

Abstract: Well development tooling has a suction head (30) or a development head (48) fitted to an eduction pipe (28). The eduction pipe is made from serially connectible double walled pipe sections with an inner conduit (38) surrounded by a coaxial outer conduit (42). The outer conduit extends beyond the inner conduit. The outer conduit is threaded on each end so that a removable slip connector joins the inner conduits of adjacent pipe sections when the outer conduits are screwed together. The eduction pipe has an eduction nozzle (44) for redirecting fluid from the outer conduit upwardly into the inner conduit to create an eduction effect in the inner conduit for drawing well fluid upwardly. The development and suction heads have a fluid conduit connected to the inner conduit of the eduction pipe. The development head has a wiper (50, 52) which slides against the walls of the well.
