Description
Technical field
The present invention relates to a kind of probe vibration-proof structure being applied in radioactive logging instrument, it is for avoiding the components and parts in probe to be subject to vibration damage.
Background technology
Radioactive logging is the nuclear physics parameter by measuring rock and medium, and research drilling geology section is found the geophysical method of oil-gas reservoir and research oil well engineering.The method of radioactive logging can be divided into two large classes, take the interaction of research gamma ray and material as basic gamma logging method with take the interaction of studying neutron and material as basic neutron well logging method.
The advantage of radioactive logging is all can carry out in open hole well, cased well, in oil base drilling fluid, high-salinity drilling fluid and dry-well, all can carry out, and is carbonate rock section and the indispensable logging method of water chemistry sedimentary section.
Radioactivity logging device has the radioactivity seeker of single spacing or different spacings, determines the degree of porosity on stratum by the count rate ratio of probe.Domestic conventional logging program is the series such as ECLIPS5700 EX2CELL2000 and HH2530 at present, and its probe inner detector has simple detector and multi-detector combination.
Logger work under bad environment, in use procedure, be hit very large, in probe, components and parts belong to accurate device, in the time of underground work, because complex instrument vibration is very large, easily cause the cracked of shield and crystal, have a strong impact on carrying out of well logging, and the Probe technology complexity of overall package is expensive, and internal components position is fixed, all make troubles for spacing adjustment, apparatus guarantee, be unfavorable for on-the-spot extensive use.
According to " SY/T5009-2007 oil well logging instrument environmental test and reliability requirement ", design, manufacture and the quality evaluation of oil well logging instrument will meet environmental test and reliability requirement, need thus a kind of mode to be reliably fixed in logger.
Summary of the invention
Therefore; the present invention proposes a kind of radioactive logging instrument probe vibration-proof structure; it is applied to radioactive logging instrument probe; the shock-reducing rubber ring of protection components and parts; its equipment is simple; be convenient to apparatus guarantee, and meet the requirement of " SY/T5009-2007 oil well logging instrument environmental test and reliability requirement ".
Radioactive logging instrument probe vibration-proof structure of the present invention mainly comprises shock-reducing rubber ring, probe, shield, wherein between probe and shield, all has shock-reducing rubber ring to connect, and all unit Series ground integral installation fits in sheath.Shock-reducing rubber ring, there are multiple annular projections on its surface; There is trough on surface in addition.In probe, can use single probe collocation shock-reducing rubber ring, also can meet many sonde configurations simultaneously, each probe shock-reducing rubber ring of all arranging in pairs or groups, is connected in series and puts into sheath, between probe combines, can place shield to meet the shielding requirements between probe.
The invention has the beneficial effects as follows: radioactive logging instrument probe vibration-proof structure has been realized the defencive function of the interior components and parts of probe of single probe or the radioactivity logging device of popping one's head in more, shock-reducing rubber ring is designed with annular protrusion, this projection can increase the fit-up gap between glue ring and sheath, make assembling more easy, surface non-uniformness has improved simultaneously, and frictional force has strengthened, and is fitted in sheath more firm, therefore it can realize vibration-damping function better, and is convenient to sheath assembling; Realize probe cabling and instrument simultaneously and run through line and arrange separately, be convenient to apparatus guarantee.
Provided description is provided and will be more obviously seen the more suitable application area of the present invention.Should be appreciated that the description of this part and specific examples, only for explanation, do not limit the scope of the invention.
Accompanying drawing explanation
By reference to the accompanying drawings, by preferred embodiment provided herein, can understand better the present invention.Accompanying drawing provided herein is for illustration purpose, and can not limit the scope of the invention, in the accompanying drawings:
Fig. 1 is the diagram of single probe assembly structure.

Fig. 3 is the diagram of shock-reducing rubber ring structure.
The specific embodiment
Now with reference to accompanying drawing, embodiments of the invention are more fully described.Following description is only exemplary in essence, does not limit the present invention and application thereof or use.
Now, in conjunction with Fig. 1,2,3, the present invention is described further.
With reference to figure 1, probe segment comprises sheath 11, probe top shock-reducing rubber ring 12, probe 13, probe bottom shock-reducing rubber ring 14 successively.Probe shock-reducing rubber ring assembling mode is: the syringe needle part of probe 13 is put into the endoporus of probe top shock-reducing rubber ring 102, the two ends of probe 13 are detected device top shock-reducing rubber ring 102, probe bottom shock-reducing rubber ring 104 is wrapped to form assembly, and entirety is put into sheath 11 and completed sonde configuration assembling.
With reference to figure 2, provide the combination of multi-detector.As shown in Figure 2, if instrument is multi-detector structure, can be by probe 13 and compensation probe 22 equipped probe top shock-reducing rubber ring 12, probe bottom shock-reducing rubber ring 14 respectively, series arrangement is in sheath, can between two groups of probes, increase shield 21 according to different probe needs of work, place it between the probe bottom shock-reducing rubber ring of main detector and the probe top shock-reducing rubber ring of compensation probe, in multi-detector, components and parts put in order by that analogy.
With reference to figure 3, show the principal character of probe shock-reducing rubber ring, having cross section at glue ring periphery is semi-circular projection 31, can absorb better extraneous vibration, and be fitted in sheath more firm, thereby eliminated the closed bad phenomenon of sheath; Have probe trough 32 and instrument in the outside of glue ring and run through wire casing 34, meet the independent cabling of probe, be convenient to instrument assembling and later period maintenance, what run through that wire casing can meet different instrument varying numbers runs through line cabling needs.Jiao Huan center need to have and coordinate through hole 33 according to detector size, and in front end, vacancy is designed with the space that can hold probe tip.
