In enforcement, entering order from the bottom up under instrument is: internal layer tubing guide shoe, internal layer oil pipe, isolating seal, internal layer oil pipe, the interior pipe screwed connection of internal layer oil pipe bottom screw thread and location sealing, then by effective for outer oil screwed connection on the outer sealed tube screw thread of location sealing, then enter internal layer oil pipe and outer oil pipe (entering under concentric bilayer) under replacing, enter length under double layer oil pipe and meet the requirements of well depth.Inside and outside water filling seating nipple, sealing drum bottom is with on screwed connection internal layer oil pipe, and its top is inserted into water filling seating nipple joint inner chamber; By the screwed connection of water filling seating nipple joint on outer oil pipe; Then, plain tubing is connected on water filling seating nipple joint top until well head oil pipe hanger.Can throw the inside of sealing drum inside and outside water distributor core to water filling seating nipple during operation, sealing drum liquid outlet inside and outside the side direction water nozzle subtend water filling seating nipple of injection well downhole flow regulator, the water nozzle of injection well downhole flow regulator bottom is directly facing to internal layer oil pipe inner chamber.
When injection water pumps in oil pipe by ground water injecting pump, current are divided into two at water filling seating nipple place:
1. a part is flow in the internal layer oil pipe of bottom by the water nozzle on water distributor core, then flows through
The centre bore of location sealing, then flow through internal layer oil pipe and note bottom (the second sand control section) stratum;
2. some injection water another is by the side direction water nozzle of water distributor core, and inside and outside water filling seating nipple, sealing drum liquid outlet flows out, then through the annular space between location sealing inner chamber and internal layer oil pipe, is then directly injected into top (the first sand control section) stratum.
The present invention connects one section of concentric double layer oil pipe on the top of sand control pipe, and then realize less injection well downhole flow regulator seating nipple moves on to hole deviation, the well depth position of steel wire operation requirement can be met, thus the conventional batch allotment operation of two-layer High angle, horizontal well can be realized.
