Description
Technical field
The present invention relates to oil exploration equipment technology, the attending device of a kind of radioactive source.
Background technology
At present, radioactive logging is applied to the assessment to formation lithology, density and porosity and survey by extensive and substantial amounts of
Amount.Up to the present this be also, the most common formation lithology density of each oil company, whole world use and the measurement of porosity
Method.Radioactive source, as ray emission part, is installed in the source chamber of instrument, constantly decays, and discharges particular energy sum
The gamma ray of amount or neutron ray, after there is a series of reaction with measured stratum in the ray discharged, then by instrument
Detect, ray counting number there is certain proportionate relationship, finally, by necessarily with the lithology and density logging on stratum and porosity
Algorithm extrapolated density of earth formations and porosity by counting rate.It may be said that there is no radioactive source or ray release device, radioactivity
Logger just cannot work, it is seen then that the effect in whole logging system of radioactive source is very important.
Meanwhile, currently used radioactive source mainly includes the CS-37 of 2ci, the am-be source of CF and 19CI of 18mci, three kinds
Radioactive source is listed in three grades of radioactive sources of country, and national environmental protection department is that its formulation has relevant law, the use of radioactive source,
Transport and storage are all to have strict control and requirement, radioactive source accident once occur, it will cause human body and the most seriously put
Penetrating property injures, the most then can slowly recover, heavy then be in peril of one's life.
For with boring radioactive logging work, radioactive source is installed in the source chamber of instrument, along with instrument together exists
Complicated stratum experiencings the adverse circumstances such as high vibrations in the High Temperature High Pressure on burn into stratum of drilling fluid, drilling process
Test, all maintenances and inspection to radioactive source of these factors propose the most harsh requirement.
The maintenance of existing radioactive source and inspection method are the simplest:
The radioactive source that opening needs to clean deposits the gag of tank, uses one meter of how long source taking rod (to be equivalent in the application
" grabbing source bar ") insert deposit in tank, by operation source taking rod, by radioactive source from deposit tank take out after, be put into the most rapidly
Placement source is cleaned and is carried out on device, after having cleaned, uses bore hole closely to observe the radioactive source after cleaning, as
Really without the foreign body such as mud, impurity on radioactive source body, just radioactive source is put into be cleaned by and checked deposit in tank, no
Then, proceed to clean and observe, after on radioactive source body without the foreign body such as mud, impurity, just radioactive source is loaded and deposits
In tank.But following five defects of this method existence:
1. in cleaning process, protection to the personnel of cleaning is not enough.For gamma ray, because only protecting gal at present
The lead clothes of horse ray, but because lead metal itself is the heaviest, so the thickness having resulted in lead clothes (not so works nothing than relatively thin
Method bears its weight), its shield effectiveness is limited, does not reaches preferable protected effect when being carried out and check work；Centering
For sub-ray, there is presently no the wearable preventer of shielding neutron ray, the NEUTRON PROTECTION device valency that market has
Lattice are much more expensive, and a set of price reaches hundreds of thousands, and dresses the most thick and heavy, is not easy to very much the carrying out of cleaning, if
Radioactive source body is the dirtiest, and that is accomplished by staff needs to take more time cleaning, it means that by the longer time
Irradiation.
2. checking process is to the injury of inspection personnel very.Because not having a set of applicable device to check, work people
Member can only carry out in-plant observation by dressing lead glasses, and lead glasses are very limited to the shield effectiveness of gamma ray, separately
Outward, neutron ray is not had any shielding action.
3. there is uncertainty in cleaning performance.In cleaning process, staff can not determine at any time on earth either with or without reaching
To preferable cleaning performance, can only first stop cleaning, then by naked eye, but without getting a desired effect,
Also need to proceed to clean.This allows whole cleaning process there is repeatability, adds the radio exposure time, to staff
Health also will result in the most serious consequence.
4. when cleaning radioactive source, in addition it is also necessary to deposit tank (there is certain alpha ray shield effect) carry out depositing radioactive source
Clean and detection, at this moment, generally require another one and deposit tank as off-duty storage tank, after having cleaned, radioactive source is put into
In off-duty storage tank, then, the deposit tank supporting with the radioactive source being cleaned by is carried out and detects, after completing, then standby
Supporting depositing in tank is transferred to the radioactive source deposited in tank.Whole cleaning process is so made to become the most loaded down with trivial details, and
Add the radio exposure time of staff.
5. checking ability is not enough, and first, if during field operation, occur that radioactive source loads the situation depositing tank difficulty, that
When return workshop checks, the best method carrys out decision problem reason.Second, check that work is by work because cleaning
Make personnel in a certain distance, completed by naked eye, so can not careful, in-plant radioactive source body be carried out
Well observe, even if source body is impaired, there is also the possibility that can not realize.
