2、umable liner equipment, running tools, etc are on location andare in good condition.对照工具检查单和装箱单,认真核查各个工具是否均在现场,状态是否完好。2. Take all relevant measurements of the equipment - lengths, ODs, IDs, etc,check hanger shear pins, +1200 psi std. shear (see check list). The liner hangerassembly will have been pr
3、essure tested at the Baker base and the linerhanger function tested, check the recorded hanger shear pressure on thedrawing supplied.逐项核查工具的几何尺寸:长度,外径,内径,等等。 检查每个剪钉,额定剪切值在+1200 psi (左右)。尾管挂总成应该已经在贝克休斯公司的基地进行过试压及功能测试。查验图纸上面所记录的尾管挂剪钉剪切压力。3. Check the compatibility of setting ball and shear out seat, a
4、nd that setting ballgoes through the liner wiper plug. Also check the compatibility of the linerwiper plug with the DP dart and the liner casing.检查座封球和剪切球座的尺寸匹配性,让剪切球试过尾管胶塞。 检查尾管胶塞与钻杆胶塞及尾管尺寸匹配性。4. Check that the liner running tool right hand release is fully made up inside thetie back extension. C t
5、ype running tools require +6 lefthand turns to make up tothe liner setting sleeve, the tool must only be made up hand tight.检查右旋丢手的送入工具已经完全正确地连接在回接筒内。C型送入工具需要左旋6圈以上来与座封套连接,上紧程度只要一人用管钳上紧就行。5. The float shoe, float collar c/w baffle and the type 2 landing collar will bemade up & thread locked (also Ca

Drift pipe before making up Float equipment.内置式浮鞋,浮箍和II型球座将被座封并锁定于套管内。检查球座剪钉,球座额定剪切值在+2500 psi (左右)在连接附件前套管需要通径。6. It is essential to drift the running string, eit

All DP singles, pup joints, which will be used HAVETO BE drifted.入井钻
8、杆的通径非常重要。有两个办法来完成,一种是在下悬挂器之前,下的最后一趟钻时,在5”钻杆内用2-1/2”套管规通过,在3-1/2”钻杆内用2”套管规通过。另一种办法是,下尾管时在猴台上对每柱钻杆逐一通径。所有入井钻杆短节都需要通径。7. Remove DP protectors on lower 10 stds of DP. This reduces the chance ofcementing string in, and allows washover to be attempted if this happens.建议最下端的10个单根钻杆不使用扶正器,这样可以减少水泥浆将钻杆“插旗杆”的
9、机会,并便于套铣钻杆(假如发生“插旗杆”事故)。BAKER OILTOOLS - BROWN LINER PRODUCTHYDRAULIC LINER SETTINGC type RUNNING TOOL and Drillable Pack-off Bushing(no Liner Top Packer)AAEG 1.007 2PROCEDURE 作业程序1.

Fill pipe regularly, maximum 3-5 stands without filling.(depending on mud weight and hole conditions)下入钻杆,用大钳上扣。不能用转盘旋
16、转上扣。如果没有事先通钻杆,则需要用通径规对每根钻杆通径。向钻杆内灌浆,每次灌浆间隔不超过3 5根(取决于泥浆密度和井眼条件)。10. Circulate at the last casing shoe.下到最下端套管鞋处循环(9-5/8”套管鞋)11. When running in open hole fill up the drill pipe as much as possible withoutinterrupting the smooth running of the liner in the hole.当尾管在裸眼内下入时,不能专门停止下钻来灌浆,在提下一柱钻杆时尽可能多地进行灌

21、ure, shut off pumps. Slack off running string and check if thehanger is set. If the hanger is not set , increase pressure in 200 psi increments,check for a set after each increase.

24、 Slick Stinger has been pulled out ofthe Drillable Pack-off Bushing, Re-entry and a seal is not garantied.固井之前,右旋钻杆(送入工具处应旋转6圈以上)使送入工具与尾管分离。上提钻杆,验证送入工具已经分离。如果尾管重量已经释放,那么向尾管上下放钻杆重量10,000-20,000磅,并在开始固井前建立起循环。注意: 上提的高度务必在插入密封管的长度之内。一旦插入密封管被从回接筒内拔出,那么插入管要再次进入回接筒并密封可靠是无法保证的。19.

Note pump efficiency at shear andadjust total displacement calculations if necessary. Slow down pumps 5 bblbefore
27、 total displacement. Bump plugs with 1000 psi over final displacingpressure. If no shear is seen, use theoretical volume only, do not overdisplace.当钻杆胶塞坐落在尾管胶塞后,泵压将上升。尾管胶塞的剪切压力为800-2,000PSI(取决于井的条件)。继续以合适的排量顶替。关注剪切尾管胶塞时的泵效,以便必要时并对顶替液量的计算作出调整。最后5桶顶替液以缓慢的排量泵注。比最后顶替压力提高1000PSI来冲击尾管胶塞,使之剪切。如果没有看见尾管胶塞剪切的
