Description
Technical field
This utility model relates to a kind of isotope releaser, specifically a kind of oil reservoir logging isotope releaser, belongs to oil field prospecting applied technical field.
Background technology
nullDevelopment and the needs of socialist modernization drive along with science and technology，People pass through geological prospecting，After being found to have the oil field of industrial value，Just can set about the work preparing to develop oil fields，The exploitation of any one mineral reserve，Its economic validity will be particular about，Less investment to be capable of，Output is many，Ultimate recovery is high，As for the exploitation in an oil field，Be particular about the target of its effectiveness，It is exactly to extend oil field production plateau as much as possible，Make the oil field crude oil that finally energy extraction is most，There are a high ultimate recovery and good economic effect，Wherein oil reservoir logging is an important operation，And isotope stains at present is the key factor affecting isotope injection profile logging，Although using cold ball is to reduce a kind of effective means that isotope stains，The way that two releases are combined is realized by current domestic main employing，But this kind of method high cost、Instrument is long，Use occasion is easily subject to limit.Therefore, for the problems referred to above, a kind of oil reservoir logging isotope releaser is proposed.
Utility model content
Have problems for above-mentioned prior art, this utility model provides a kind of oil reservoir logging isotope releaser, by arranging two cylinder sources in release, achieve substep of once going into the well and discharge cold ball and the purpose of isotope granule, thus improve the accuracy of measurement data, solve problem present in background technology.
For achieving the above object, the technical solution adopted in the utility model is: a kind of oil reservoir logging isotope releaser, including housing and the joint that is connected to described shell one end；One end of described housing arranges control module, and motor is installed in the side of control module；The side of described joint arranges cold ball cylinder, and roller bearing is installed in the side of cold ball cylinder；Between described roller bearing and motor, screw mandrel is set；Piston is installed in described enclosure interior one end, and the top of piston is respectively provided with inlet opening and apopore；Isotope cylinder is set between described inlet opening and apopore.
Further, the diameter of described screw mandrel is less than the diameter of roller bearing, and screw mandrel is installed in parallel in the center of housing.
Further, described piston has two, and size shape is the most vertical with housing.
Further, described inlet opening and apopore are through to enclosure interior.
Further, described housing is overall in yi word pattern structure.
The beneficial effects of the utility model are:
1, achieve substep of once going into the well and discharge cold ball and the purpose of isotope granule, i.e. release has two cylinder sources, one of them fills cold granule, it is commonly called as cold ball, another dress carries active isotope granule, first cold ball is discharged before measurement, allow its absorption on the casing wall measuring well section, discharge isotope granule the most again, to reduce the absorption on sleeve pipe of the isotope granule, thus improve the accuracy of measurement data, on the basis of former electric releaser, the double source cylinder electric releaser of design can preferably solve isotope absorption and stain the impact on well logging；
2, according to different logging requirements, the isotope cylinder of different capabilities can be changed, whole instrument need not be changed, and can be on-the-spot quickly with changing, transition joint, isotope cylinder being pulled down, bottom fitting has just become single source cylinder electric releaser after docking with cold ball cylinder, can be used for tradition logging method and measures, cold ball cylinder, transition joint, isotope cylinder, bottom fitting can directly be pulled down from instrument, the cleaning of instrument after well logging, maintain very convenient.

Fig. 1 is this utility model overall structure schematic diagram.
In figure: 1, control module, 2, motor, 3, screw mandrel, 4, roller bearing, 5, cold ball cylinder, 6, joint, 7, inlet opening, 8, isotope cylinder, 9, apopore, 10, housing, 11, piston.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, a kind of oil reservoir logging isotope releaser, including housing 10 and the joint 6 that is connected to described housing 10 one end；One end of described housing 10 arranges control module 1, and motor 2 is installed in the side of control module 1；The side of described joint 6 arranges cold ball cylinder 5, and roller bearing 4 is installed in the side of cold ball cylinder 5；Between described roller bearing 4 and motor 2, screw mandrel 3 is set；Piston 11 is installed in the internal one end of described housing 10, and the top of piston 11 is respectively provided with inlet opening 7 and apopore 9；Between described inlet opening 7 and apopore 9, isotope cylinder 8 is set.
As optimisation technique scheme of the present utility model: the diameter of described screw mandrel 3 is less than the diameter of roller bearing 4, and screw mandrel 3 is installed in parallel in the center of housing 10；Described piston 11 has two, and size shape is the most vertical with housing 10；It is internal that described inlet opening 7 and apopore 9 are through to housing 10；Described housing 10 entirety is yi word pattern structure.
nullThis utility model is in use，This kind of isotope releaser is roughly divided into screw mandrel 3 drive mechanism、The transition joint of cold ball cylinder 5，Isotope cylinder 8，When switching on power，After motor 2 starts，Control module 1 carries out being set and controlled of relevant parameter，During instrument work, screw mandrel 3 drive mechanism promotes cold ball cylinder 5 inner carrier 11，Discharge after cold ball piston 11 puts in place and automatically power off，Piston rod in isotope cylinder 8 is motionless，Isotope cylinder 8 keeps closing，Then motor 2 drives screw mandrel 3 to rotate，Screw mandrel 3 is slided to the right by roller bearing 4，Spring contact feed screw nut connects shell body 10，When half stroke passed by by screw mandrel，After cold ball cylinder 5 inner piston rod puts in place，Spring departs from feed screw nut，Motor power-off，Release isotope，Motor 2 works on，Inlet opening 7 water filling，Screw mandrel 3 nut is turned right slip，Apopore 9 water outlet，Realize combining cold ball and isotope release，After isotope cylinder 8 inner piston rod is opened and is put in place，Screw mandrel automatically dallies and returns again to.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
