Description
Technical field
The present invention relates to a kind of probe vibration-proof structure applied in radioactive logging instrument, it is used to avoid in probe
Component is vibrated damage.
Background technique
Radioactive logging is the nuclear physics parameter by measuring rock and medium, studies drilling geology section, finds oil gas
The geophysical method of hiding and research oil well engineering.The method of radioactive logging can be divided into two major classes, i.e., penetrated with studying gamma
Gamma logging method based on the interaction of line and substance and the neutron based on the interaction for studying neutron and substance
Well logging method.
The advantages of radioactive logging, can be carried out in open hole well, cased well, in oil base drilling fluid, high salinity drilling well
It can be carried out in liquid and dry-well, be carbonate rock section and the indispensable logging method of water chemistry sedimentary section.
Radioactivity logging device have single source away from or it is not homologous away from radioactivity seeker, by the count rate ratio of detector come
Determine the porosity on stratum.Common logging program domestic at present is that ECLIPS5700 EX2CELL2000 and HH2530 etc. are
Column, probe inner detector have simple detector and multi-detector combination.
Logger working environment is severe, is hit in use process very big, and interior component of popping one's head in belongs to accurate device,
Since complex instrument vibration is very big when underground work, it is be easy to cause the fragmentation of shield and crystal, seriously affects well logging work
The development of work, and the Probe technology complexity of overall package is expensive, and internal components position is fixed, for source away from adjustment,
Apparatus guarantee is all made troubles, unfavorable large-scale use on site.
According to " SY/T5009-2007 oil well logging instrument environmental test and reliability requirement ", oil well logging instrument is set
Meter, manufacture and quality evaluation will meet environmental test and reliability requirement, and a kind of reliable way is thus needed to be fixed on well logging
In instrument.
Summary of the invention
Therefore, the invention proposes a kind of radioactivity logging device probe vibration-proof structure, it is applied to radioactive logging instrument
Probe protects the vibration damping rubber ring of component, and equipment is simple, is convenient for apparatus guarantee, and meets " SY/T5009-2007 petroleum survey
Well instrument environments test and reliability requirement " requirement.
Radioactivity logging device probe vibration-proof structure of the invention mainly includes vibration damping rubber ring, detector, shield, wherein visiting
Surveying between device and shield has the connection of vibration damping rubber ring, and all components are integrally assemblied in sheath in series.Vibration damping rubber ring, table
There are multiple annular projections in face；In addition there is cabling channel on surface.Single probe collocation vibration damping rubber ring can be used in probe, while can also
To meet Multi probe structure, each probe is arranged in pairs or groups vibration damping rubber ring, and series connection is put into sheath, can be between probe combination
Shield is placed to meet the shielding requirements between probe.
The beneficial effects of the present invention are: radioactivity logging device probe vibration-proof structure realizes single probe or Multi probe radioactivity
The defencive function of component in the probe of logging instrument, shock-reducing rubber ring design have annular protrusion, which can increase rubber ring and shield
Fit-up gap between set keeps assembly more easy, while surface non-uniformness improves, and frictional force increases, and is fitted into shield
It is more secured in set, therefore vibration-damping function can be better achieved in it, and assembles convenient for sheath；Simultaneously realize probe cabling and
Instrument is individually arranged through line, is convenient for apparatus guarantee.
It will be apparent from seeing the more suitable application areas of the present invention by provided description.It should be appreciated that this part is retouched
It states and is merely to illustrate with specific examples, is not limit the scope of the invention.
