Description
Technical field
The utility model is related to oil well seal layer sampling and testing technical field, and particularly relating to one kind can insulate whole layering well section
Well logging twin packer.
Background technology
The majority for being presently used for the well logging packer of cased well perforated interval is unidirectional packing, and its packing is short apart from some, right
Layer point in the middle of thicker layering can not carry out formation pressure test, can not absorb the real fluid sample on stratum.
And the thickness for being layered well section is probably 2,3m, 5,6m, it is also possible to reach more than 10m.General method is that design is several
The Special packer of size is planted, is once gone into the well using a kind of, the logging tasks for meeting this size layering are completed, then to ground
The packer of another kind of size, then lower borehole logging tool are changed, till the layering of the well various sizes has been surveyed.Cause packer
Species is more, is added significantly to cost, reduces testing efficiency.
Utility model content
The purpose of this utility model is to provide a kind of well logging twin packer for insulating whole layering well section, and once going into the well can
To complete the overall packing to the layering of various thickness, to carry out dynamic characteristic well logging and the real fluid of its internal each stratum point
The acquisition of sample.
To achieve these goals, the utility model employs following technical scheme：One kind can insulate whole layering well
The well logging twin packer of section, including sleeve pipe and it is arranged at instrument body up and down in sleeve pipe, it is characterised in that the instrument
Body includes twin packer epimere and twin packer hypomere；
The twin packer epimere mainly includes two parts, and a part is on packing element and twin packer on twin packer epimere
The upper packer of formation is sealed between section lower rubber cylinder, another part is liquid input section；
The twin packer hypomere is to seal shape by between packing element on twin packer hypomere and twin packer hypomere lower rubber cylinder
Into lower packet；
Connected by connector between the twin packer epimere and twin packer hypomere.
Wherein, segment length is 3m on the twin packer, and upper packer length is 2m, and feed liquor segment length is 0.5m；It is described
Segment length is 3m under twin packer.
Further, the instrument body hypomere is additionally provided with the tail bone for facilitating its descending.
The beneficial effects of the utility model are：After using above-mentioned twin packer, for lift height is probably 2,3m, 5,
6m, 7, the layering of 8m, then in pack-off sealing area, can easily complete test or true sample according to the design of test point
Intake；Once going into the well can complete the overall packing to the layering of various thickness, to carry out the dynamic of its internal each stratum point
Signature log and the acquisition of real fluid sample.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment technical scheme, below will be to make needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only the utility model in order to more clearly
The utility model embodiment or technical scheme of the prior art are illustrated, below by institute in p- embodiment or description of the prior art
The accompanying drawing that needs are used is briefly described, for those of ordinary skill in the art, before creative work is not paid
Put, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is structural representation of the present utility model；
Fig. 2～4 are situation schematic diagram when the huge thickness of the utility model instrument test is layered.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
A kind of well logging twin packer for insulating whole layering well section as shown in Figure 1, including sleeve pipe (2) and it is arranged at set
Up and down instrument body (1) in pipe (2), the instrument body (1) is including twin packer epimere (5) and twin packer hypomere
(6)；Instrument body (1) is up and down in oil well casing (2), and the perforated interval (3) for finding well logging purpose oil reservoir is logged well, and is
This must be tested the design point of liquid input section (4) midpoint alignment perforated interval (3) well section on instrument body (1).Before test,
Allow on twin packer epimere packing element (9) on packing element (7), twin packer epimere lower rubber cylinder (8) and twin packer hypomere, double first
Packer hypomere lower rubber cylinder (10) is setting.Packing element state shown in Fig. 1 is exactly setting state.Packing element (7) on twin packer epimere
And twin packer epimere lower rubber cylinder (8) between, on twin packer hypomere packing element (9) and twin packer hypomere lower rubber cylinder (10) it
Between, it is pack-off sealing area.Connected using connector (11) between twin packer epimere (5) and twin packer hypomere (6), instrument
Body (1) bottom device Wei Cone (12), is easy to instrument descending.There is well liquid (13) in well.
Situation when Fig. 2 left sides component represents that the huge thickness of instrument test is layered, this is that instrument liquid input section is located at this huge thick layering
The top when test；Situation when component represents that the huge thickness of instrument test is layered in the middle of Fig. 3, at this moment instrument liquid input section is positioned at this
Test during huge thick layering medium position, it is noted that the top of now huge thick layering is still in packing sealing state.Now feed liquor
Away from layering top 2.25m, it is 2.25m+3.25m=5.50m to be layered by the length of packing sealing to Duan Zhongdian；Fig. 4 right sides component
Situation during the huge thick layering of instrument test is represented, this is test when instrument liquid input section is located at the lower end of this huge thick layering, now
Layering lower end is insulated sealing, and liquid input section midpoint is 3.25m away from layering distance from bottom, and layering is by the length of packing sealing
2.25m+3.25m=5.50m.Consider layering top and two kinds of situations of sealing are insulated by packing sealing and layering bottom, always
Packing interval 11.0m, can carry out the test for insulating test and obtaining true sample by each floor point in total packing area.
Huge thick layering more than 11.0m is actually rare, and upper and lower ends interval is first tested during test, and middle interval is perhaps
There is no need to test again, even if test leakage, may affect also little to the evaluation of the layering.
For lift height is probably 2,3m, 5,6m, 7, the layering of 8m, then in pack-off sealing area, can be according to survey
The design of pilot, easily completes test or the intake of true sample.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
