ubing before the displacing valve is to be opened.(3) Landing a BFC Blanking Plug in a BFC Seating Nipple or Sliding Sleeve below the packer. Inmost cases, the plug can be run, the packer set, and the plug retrieved all in one trip.常見封隔器TO RELEASE THE PACKER: The Standard TwinSeal Packer is retrieved with straight pull on thelong string. The modified version for coiledtubing applications features hydraulic releasingto minimize tensile requirements. Anydifferentialpressure acting across packer should beequalized or pensated for prior to releasingpacker.常見封隔器FEATURES/BENEFITSl ByPass Port In all sizes, the bypass area is thelargest available (7” 3/4” bypass area。 5l/2 l/2” bypass area). This enables use of the largerported pilot valves necessary for an efficientchamber lift installation.l Simple and Easy to setThe packer is set by setdownweight only. No hydraulic pressure orrotation is required.l Simple, Positive ReleaseThe packer is releasedby a straight pick up of the tubing string.l Full Bore The borethrough the packer is thesame as tubing drift diameter or larger.l Flexible Hookup The hookup provides theflexibility and inherent advantages of a retrievablepacker.常見封隔器TO SET THE PACKER:1. Run and set a Baker Retainer Production Packer.2. Make up a production tube and a locator sealassembly onto the bottom of the tubing string.3. Make up the Model “C” ByPass CompressionPacker and Bypass Side Pocket Mandrel at thedesired location in the tubing string, and run thetubing string into the well until the locator sub ofthe locator seal assembly lands on the ProductionPacker.4. Apply the required setdown weight to packoffthe packing elements.常見井下工具 (一) KPX100偏心注水工作筒: 用于水井注水作業(yè);投放水嘴。:A、 總 長(zhǎng): 1832mm; B、 剛體通徑: ?49mmC、 最大剛體外徑 。?115mm; D、 工作壓力: ?30MPaE、 工作溫度 :?120 0C。 F、 上下連接扣型: 27/8 UP TBGG、 適用套管范圍: ??121mm常見井下工具(二) KSS115管柱伸縮器:用于水井分層注水作業(yè);來補(bǔ)償管柱軸向變形量。:A、 總 長(zhǎng): 1260mm; B、 最大剛體外徑: ?115mm;C、 通 徑: ?50mm。 D、 解封壓力: 1820MPaE、 工作壓力: ?30MPa F、 工作溫度: ?120?C。常見井下工具(三 )KSL90水力循環(huán)凡爾: 用于水井分層注水作業(yè);使封隔器座封, 并能溝通油套環(huán)空,進(jìn)行反洗井作業(yè)。:A、 總 長(zhǎng): 600mm; B、 最大剛體外徑: ?90mm;C、 打開壓力: 1520MPa D、 工作溫度: ?120?C。E上連接扣型: 27/8 TBG常見井下工具(四) KDS108A丟手接頭: 用于油井找堵水作業(yè)、負(fù)壓射孔、選層酸化等作業(yè)。:A、 總 長(zhǎng): 580mm; B、 最大剛體外徑: ?108mm;C、 丟手方式: 投球丟手 D、 丟手壓力: ?15MPaE、 工作溫度: ?120 0C。 F、 上下連接扣型: 27/8 UP TBG 常見井下工具(五) KSL100水力開關(guān)滑套:用于油田找堵水作業(yè)、分(選)層酸化等作業(yè),打開或關(guān)閉目的層。:A、 總 長(zhǎng): 815mm; B、 最大剛體外徑: ?100mm;C、 最小內(nèi)徑:投球前: ?30mm; 投球后:?50mmD、 鋼球直徑: ?38mm
