Summary of the invention
The present invention seeks to overcome the defective that above-mentioned prior art exists, a kind of good seal performance is provided, can takes a sample and be beneficial to the true displacement formula sampler that changes appearance.
To achieve these goals; The present invention has adopted a kind of displacement formula sampler; By locker, a commentaries on classics appearance valve, elastic positioning pin, commentaries on classics appearance mouth valve, packed-piston, floating piston, piston guide rod, sampling tube, liquid-filling valve, restriction choke, air chamber joint, pressure-relief valve; Air collector, mozzle, air chamber valve, valve rod, clock controller are formed; Locker, sampling tube, restriction choke, air collector, air chamber valve and the clock controller composition external shell that is threaded successively, the tube wall of sampling tube are provided with locating hole, change an appearance outlet and a sample inlet; Packed-piston is installed on the upper end of the locker in the sampling tube, and its upper surface is positioned on the center line of the outlet of commentaries on classics appearance and sample inlet on the sampling tube tube wall, changes an appearance valve, changes an appearance mouth valve, elastic positioning pin is installed in respectively on the body of packed-piston; Piston guide rod is positioned at the chamber of sampling tube, be inserted in floating piston after, be threaded with packed-piston; The liquid-filling valve of packing on the restriction choke; The air chamber joint is provided with central through hole, is installed on the restriction choke upper end through its outer tube wall upper shoulder; Mozzle one end is threaded with the air chamber valve and fills in the air collector, and its other end is threaded with the central through hole of air chamber joint; Valve rod is installed in the centre bore of air chamber valve.
Piston guide rod is " T " shape structure.
The mozzle middle part is a coil arrangement.
The invention has the beneficial effects as follows: the present invention accomplishes sample circuit through moving up and down of floating piston in the sampler to change appearance; Good seal performance; Be applicable to that the various fluid sample sample circuits in down-hole, oil field change appearance, change appearance process nonhazardous and can guarantee change the authenticity of sample.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; The present invention is by locker 1, a commentaries on classics appearance valve 2, elastic positioning pin 3, a commentaries on classics appearance mouthful valve 4, packed-piston 6, floating piston 8, piston guide rod 9, sampling tube 11, liquid-filling valve 12, restriction choke 13, air chamber joint 14, pressure-relief valve 15; Air collector 16, mozzle 17, air chamber valve 18, valve rod 19, clock controller 20 are formed; Locker 1, sampling tube 11, restriction choke 13, air collector 16, air chamber valve 18 and the clock controller 20 composition external shell that is threaded successively, the tube wall of sampling tube 11 are provided with locating hole 5, change an appearance outlet 7 and a sample inlet P; Packed-piston 6 is installed on the upper end of the locker 1 in the sampling tube 11; Its upper surface is positioned on the center line of commentaries on classics appearance outlet 7 and sample inlet P on sampling tube 11 tube walls, changes an appearance valve 2, changes an appearance mouthful valve 4, elastic positioning pin 3 is installed in respectively on the body of packed-piston 6; Piston guide rod 9 is positioned at the chamber of sampling tube 11, be inserted in floating piston 8 after, be threaded with packed-piston 6; The liquid-filling valve 12 of packing on the restriction choke 13; Air chamber joint 14 is provided with central through hole, is installed on restriction choke 13 upper end through its outer tube wall upper shoulder; Mozzle 17 1 ends are threaded with air chamber valve 18 and fill in the air collector 16, and its other end is threaded with the central through hole of air chamber joint 14; Valve rod 19 is installed in the centre bore of air chamber valve 18.
The described pressure-relief valve 15 that on air collector 16, is equipped with.
Described piston guide rod 9 is " T " shape structure.
Described mozzle (17) middle part is a coil arrangement.
Space between air chamber joint 14 and the air chamber valve 18 is air chamber K.
Before the sampling, in the chamber of sampling tube 11, inject the displacing fluid 10 of certain pressure, regularly with clock controller 20 through the liquid-filling valve on the restriction choke 13 12.
When the present invention being gone into the well sampling, drive valve rod 19 by clock controller 20 and move up, open air chamber valve 18 valve ports, displacing fluid 10 is communicated with air collector 16 interior air chamber K through central through hole, mozzle 17, the air chamber valve 18 of air chamber joint 14; Sample inlet P on the sampling tube 11 is communicated with treating sample thief; Floating piston 8 begins to move up along piston guide rod 9 under the sample strain effect, and sample gets in the chamber of sampling tube 11 through sample inlet P, and displacing fluid 10, mozzle 17 and restriction choke 13 will be controlled the translational speed of floating piston 8; Simultaneously; Displacing fluid 10 gets into air chamber K in the air collector 16 through central through hole, mozzle 17, restriction choke 13 and the air chamber valve 18 of air chamber joint 14, when floating piston 8 arrives lower surface, piston guide rod 9 top, drives packed-piston 6 and moves up; Making changes appearance mouthful valve 4 and elastic positioning pin 3 and aligns spacingly with changeing appearance outlet 7 and spacing hole 5 respectively, and sampling finishes.
