Abstract
The invention provides a plunger sealing mechanism of a high-temperature and high-pressure formation fluid analysis meter. The plunger sealing mechanism comprises a pressing cap (1), a plunger (4) and a barrel (5). The pressing cap (1) is connected to one end of the barrel (5) through threads, one end of the plunger (4) is arranged in the barrel (5), an annular sealing piece (2) is arranged at the joint of the pressing cap (1) and the barrel (5), a supporting spring (3) is arranged between the sealing piece (2) and the barrel (5), fluid (6) is arranged in the barrel (5), annular grooves (7) are formed in the inner side and the outer side of the sealing piece (2) respectively, and the sealing piece (2) is made of high polymer materials. The plunger sealing mechanism of the high-temperature and high-pressure formation fluid analysis meter has the technical advantages that the work temperature of the high-temperature and high-pressure formation fluid analysis meter can be 250 DEG C, the pressure can be 70 MPa, and the high-temperature and high-pressure formation fluid analysis meter can operate for a long time.
Description
Technical field
The plunger seal mechanism that the present invention relates to a kind of HTHP formation fluid analyzer, belongs to fluid analysis technical field.
Background technology
Formation fluid analyzer is mainly the phase Characteristics of measuring dirty oil, viscous crude, natural gas, condensate gas, volatile oil, directly to observe hydrocarbon stratum change at the oil gas of different temperatures pressure condition by a container with transparent windows, by dew-point pressure measures, etc. the process of the test calculating such as appearance exhaustion test, difference condensation arrange out a whole set of analyzing test data.Calculate phasor according to relevant software.
Existing HTHP formation fluid analyzer has following weak point: because running environment is high-temperature high-pressure state, seal in the past can not meet existing duty, temperature can only reach 120 ℃, and pressure only has 60MPa, can not meet oil field requirement of experiment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of plunger seal mechanism of HTHP formation fluid analyzer is provided.
The plunger seal mechanism of HTHP formation fluid analyzer of the present invention, comprise pressure cap (1), plunger (4) and cylindrical shell (5), described pressure cap (1) is threaded connection the one end in cylindrical shell (5), one end of described plunger (4) is located in cylindrical shell (5), described pressure cap (1) and cylindrical shell (5) junction are provided with annular seal (2), between said seal (2) and cylindrical shell (5), be provided with support spring (3), in described cylindrical shell (5), be provided with liquid (6), inner side and the outside of described seal (2) are equipped with annular groove (7), described seal (2) adopts macromolecular material to make.
Described macromolecular material is polyether-ether-ketone (PEEK).
The plunger seal mechanism of HTHP formation fluid analyzer of the present invention has following technique effect: adopt macromolecular material to improve seal (2) strength of materials, and be equipped with annular groove (7) by the inner side at seal (2) and outside, entirety is cut down the thickness of seal, the equipment operating temperature of making reaches 250 ℃, pressure 70MPa long-term operation.
Because the strength ratio of material is higher, the support spring of existing seal is as shown in Figure 3 difficult to recover the distortion of seal, and in addition, entirety is cut down the words of the thickness of seal, existing seal intensity as shown in Figure 3 will entirety decline, and can not meet the requirement of 70MPa.
