The patent No. is that 022399585 Chinese patent discloses a kind of water injection well Operating Pressure device, and its structure is made up of movable slips, stationary slip, blowout preventer, preventer and hydraulic cylinder, and stationary slip is installed on the blowout preventer top, and preventer is installed in the bottom.This device has been brought into play effect for oil exploitation well Operating Pressure, can only carry out Operating Pressure to single tubing string but also exist simultaneously, stop up Operating Pressure and can not carry out segmentation to the demixing injection-production process pipe string of complexity, especially to those down-hole process pipe strings that has a plurality of layering tool strings, carry out shortcoming or deficiency that the powerless especially grade of Operating Pressure is stopped up in segmentation.
Three, summary of the invention
The purpose of this utility model provides a kind of improved demixing injection-production column jacket segmenting obstruction pressed apparatus for work, and employing is pressed with make-up device and band and thrown the co-ordinative construction that stifled device matches, and carries out the Operating Pressure of demixing injection-production pipe column tools string effectively, safely.
Demixing injection-production column jacket segmenting obstruction pressed operation isolated plant described in the utility model, comprise lower transverse beam, fixedly pipe clamping device, partly seal blowout preventer, seal stifled device of blowout preventer, spherical blow-out preventer, hydraulic cylinder, cross beam type card device, make-up device, plug valve and throwing and anti-top safety slip entirely.Described lower transverse beam flatly is installed on the four-way junction of casing top, and the lower transverse beam two ends are connected with the hydraulic cylinder vertical fixing, and hydraulic cylinder top is connected with the transverse beam type pipe clamping device two ends are vertical respectively.Be equipped with in turn more than the lower transverse beam middle part fixedly pipe clamping device, partly seal blowout preventer, seal blowout preventer, spherical blow-out preventer entirely.Described make-up device runs through crossbeam pipe clamping device, spherical blow-out preventer, seals blowout preventer and partly seal blowout preventer entirely, and the make-up device upper end is connected with plug valve in turn and throws stifled device.
Wherein, described make-up device comprises the interior pipe that connects in turn under the box cupling, middle box cupling, pipe nipple, following box cupling and slot pipe.Describedly go up under the box cupling, on the interior pipe on the middle box cupling spring and sliding sleeve be installed in turn.Box cupling upper end during described spring is installed on, sliding sleeve is installed on the spring upper end.Described lower transverse beam and crossbeam pipe clamping device are that horizontal parallel is installed.
In order to prevent that instrument with the last top power of the high pressure in the lower tubular column to the tubing string that has blanking plug that just unloaded, is equipped with anti-top safety slip on the tubing string of described transverse beam type pipe clamping device lower end.
The utility model has following advantage compared with prior art:
1, function is many, and adopting process and isolated plant are linked together, can not only carry out the Operating Pressure of single tubing string, and can carry out various demixing injection-production column jacket segmenting obstruction pressed operations;
2, simplify process pipe string, efficient height;
3, adopt make-up device, can prevent the damage of tubing string screw thread, prolong its application life;
