Description
Technical field
The present invention relates to oil exploration equipment technology, espespecially a kind of attending device of radioactive source.
Background technology
At present, radioactive logging is by extensively and largely applied to the assessment and survey to formation lithology, density and porosity
Amount.Up to the present this is also the most common formation lithology density and the measurement of porosity that each oil company in the whole world uses
Method.Radioactive source is installed in the source chamber of instrument, constantly decay as ray emission part, discharges particular energy sum
The gamma ray or neutron ray of amount, after with measured stratum a series of reaction occurs for the ray discharged, then by instrument
Detect, ray count number with the lithology and density logging on stratum and porosity certain proportionate relationship be present, finally, by certain
Algorithm density of earth formations and porosity are extrapolated by counting rate.It may be said that without radioactive source or ray release device, radioactivity
Logger can not just work, it is seen then that the effect in whole logging system of radioactive source is very important.
Meanwhile the radioactive source used at present mainly includes 2ci CS-37,18mci CF and 19CI am-be sources, three kinds
Radioactive source is listed in national three-level radioactive source, and national environmental protection department formulates for it related law, the use of radioactive source,
Transport and storage are all to have strict control and requirement, once radioactive source accident occurs, it will human body is caused seriously to put very much
Penetrating property injures, and gently then can slowly recover, heavy then be in peril of one's life.
For with radioactive logging work is bored, radioactive source is installed in the source chamber of instrument, as instrument together exists
The adverse circumstances such as the high vibrations in the HTHP on the burn into stratum of drilling fluid, drilling process are experiencing in complicated stratum
Test, maintenance and inspection of these factors all to radioactive source propose more harsh requirement.
Existing radioactive source maintenance and inspection method are very simple：
The gag for the radioactive source storage tank for needing to clean is opened, using one meter of source taking rod how long (equivalent in the application
" grabbing source bar ") insertion storage tank in, by operating source taking rod, by radioactive source from storage tank in take out after, be then put into rapidly
Cleaned on the cleaning device of placement source, after the completion of cleaning, closely the radioactive source after cleaning is observed using bore hole, such as
Without foreign matters such as mud, impurity on fruit radioactive source body, just radioactive source is put into storage tank that is cleaned and having checked, it is no
Then, continue to clean and observe, after on radioactive source body without foreign matters such as mud, impurity, just radioactive source is loaded and deposited
In tank.But there is following five defects in this method：
1. the protection to cleaning personnel in cleaning process is insufficient.For gamma ray, because only protecting gal at present
Lead clothes of horse ray, but because lead metal is very heavy in itself, have resulted in that thickness ratio that lead takes is relatively thin (not so to work nothing
Method bears its weight), its shield effectiveness is limited, and preferable protecting effect is not reached when being cleaned and checking work；Centering
For sub- ray, there is presently no the wearable protector of shielding neutron ray, the NEUTRON PROTECTION device valency that in the market has
Lattice are very expensive, and a set of price reaches hundreds of thousands, and wearing is very thick and heavy, is not easy to very much the progress of cleaning, if
Radioactive source body is very dirty, and that just needs staff to need to take more time to clean, it means that by the longer time
Irradiation.
2. injury of the checking process to inspection personnel is very.Because being checked without a set of suitable device, work people
Member can only carry out observation closely by dressing lead glasses, and lead glasses are very limited to the shield effectiveness of gamma ray, separately
Outside, any shielding action is not had to neutron ray.
3. cleaning performance exists uncertain.In cleaning process, staff can not determine at any time on earth either with or without up to
To preferable cleaning performance, it can only first stop cleaning, then by naked eye, but if being not reaching to expected effect,
Also need to continue to clean.This allows whole cleaning process repeatability to be present, the radio exposure time is added, to staff
Body will also cause more serious consequence.
4. clean radioactive source, it is also necessary to which the storage tank (having certain alpha ray shield effect) for depositing radioactive source is carried out
Cleaning and detection, at this moment, another storage tank are generally required as off-duty storage tank, after the completion of cleaning, radioactive source is put into
In off-duty storage tank, then, the storage tank supporting with cleaned radioactive source is cleaned and detected, after the completion of, then standby
It is transferred to the radioactive source in storage tank in supporting storage tank.Whole cleaning process is so set to become very cumbersome, and
Add the radio exposure time of staff.
5. checking ability is insufficient, and first, if during field operation, there is radioactive source and loading the difficult situation of storage tank, that
When return workshop checks, carry out decision problem reason without method good enough.Second, because cleaning checks that work is by work
Make personnel in a certain distance, completed by naked eye, thus can not carefully, closely to the progress of radioactive source body
Observation well, even if source body is damaged, there is also the possibility that can not be realized.
