Description
Technical field
The utility model is related to a kind of sampling valve, the multi-layer testing sampling valve of especially a kind of Oil testing.
Background technology
Oil testing is the important step that oil field produces.Through production practices for many years, Oil testing technology has developed
It is to test valve and the packer and pressure gauge tubing string construction technology as main tool.Test valve as link up formation fluid with
Indispensable main tool in tubing string, defines the test valve of three kinds of different structures.One kind is real by above putting square tube post
The opening and closing (with MFE test valve as representative) of existing valve body；A kind of is to realize the opening and closing of valve body by way of annular space is suppressed (with APR
Test valve is representative)；One kind is also had to be by ground pitching, the mode suppressed in tubing string realizes the opening and closing of valve body (with sleeve type
Test valve is representative), these three test valves all have the characteristics that itself and technique for applying, all can not realize formation sampling, many simultaneously
Layer test construction process requirement.But, progress into the later stage with oil field development, multilayer hierarchical testing technology and rapid stratum take
Sample is increasingly paid attention to by oil field.In order to adapt to oilfield technology demand, need development multi-layer testing integrated with formation sampling
Measuring technology.
Utility model content
Technical problem to be solved in the utility model is it is proposed that one kind has multi-layer testing and the dual work(of formation sampling
The multi-layer testing sampling valve of energy.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of multi-layer testing sampling valve, bag
Include mandrel and housing, housing is cylindrical shape, is formed with the passage of oared segrne pii in the hypomere of housing cavity, housing tip is provided with
The through hole matching with outside diameter of mandrel, the mandrel with main fluid passageway passes through through hole, and through-hole wall is embedded with the sealing of twice " o " type
Circle, plays sealing function when mandrel moves up and down in through-holes, is formed in a circle and housing on the outer wall of mandrel lower half
The bulge loop that chamber matches, bulge loop outer peripheral face is embedded with twice " o " type sealing ring, makes be formed between mandrel, bulge loop and housing cavity
Airtight sampling cavity, is provided with mandrel STH in the upper side of mandrel, when bulge loop bottom be located at oared segrne pii above in
During the portion of bottom of chamber, mandrel STH is placed exactly between twice " o " the type sealing ring of case top through hole, makes sampling cavity be airtight
Cavity.
The beneficial effects of the utility model are：It is capable of the internal full-bore of tubing string, facilitate subsequent construction measure；Realize one
Plow tubing string multilayer sampling；Realize multilayer zonal testing, for the testing sequence between different layers, can be pacified according to actual needs
Row；Test sampling valve opens and closes just for single layer, does not affect the connection of sprue.

Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is described in further detail：
As shown in Figure 1, 2, multi-layer testing sampling valve of the present utility model, including mandrel 8 and housing 2, housing 2 is cylinder
Shape, is formed with the passage of oared segrne pii 6 in the hypomere of housing 2 inner chamber, and the top of housing 2 is provided with and is matched with mandrel 8 external diameter
Through hole, the mandrel 8 with main fluid passageway 10 pass through through hole, through-hole wall is embedded with twice " o " type sealing ring 1,3, when mandrel 8
Play sealing function when moving up and down in through-holes, a circle is formed on the outer wall of mandrel 8 lower half and matches with housing 2 inner chamber
Bulge loop 11, bulge loop 11 outer peripheral face is embedded with twice " o " type sealing ring 4,5, and making can shape between mandrel 8, bulge loop 11 and housing 2 inner chamber
Become airtight sampling cavity 7, the upper side of mandrel 8 is provided with mandrel STH 9, when bulge loop 11 bottom is located at oared segrne pii 6
During the intracavity bottom of top, mandrel STH 9 is placed exactly between twice " o " the type sealing ring 1,3 of housing 2 top through hole, makes
Sampling cavity 7 is airtight cavity.
Before construction, multi-layer testing sampling valve of the present utility model is serially connected with the middle of layer position to be tested (if carrying out multilayer formation testing
Test, then concatenate this device in each interlayer to be measured), prepare into well.Multi-layer testing sampling valve of the present utility model is entering well mistake
Cheng Zhong, test sampling valve is closed, and sees Fig. 1, main fluid passageway 10 is only communicated with upper lower tubular column, and sampling cavity 7 is in sealing
It is in vacuum state, the fluid of layer to be measured nor entrance tubing string around test sampling valve under systemic effect；When needing to certain
When layer drives a well, housing 2 is pushed up by the executing agency being concatenated by tool lower portion, the state making test sampling valve be in out, and sees
Fig. 2.Now, around test sampling valve, the fluid of layer to be measured enters sampling cavity 7 by oared segrne pii 6, then passes through mandrel STH 9
Enter main fluid passageway 10, ground is discharged by main fluid passageway 10, carry out the tested production value prediction of individual layer；After the completion of test,
Housing 2 is pulled down by the executing agency of bottom concatenation, and now formation fluid, because of the flowing of fluid, fills with sampling cavity 7, housing
2 during descending, is full of fluid all the time, when test sampling valve is in Fig. 1 state again, in whole sealing system in sampling cavity 7
Under effect, formation fluid is preserved in sampling cavity 7.
By the way of the utility model applies power using down-hole, realize the switch of valve body, the stream after the completion of test, in stratum
Body, while valve body is closed, is remained in test valve.This apparatus structure is reliable, simple to operate, is simply grasped by ground
Make can achieve switch and the sampling of test valve, meanwhile, valve body only controls the fluid stream around itself to enter primary path, does not affect up and down
The passage by tubing string for the fluid, can realize multiple formation testings and sampling by one-trip string.The utility model can be to greatest extent
Realize a tubing string and carry out multiple construction technologies, there is reduction Oil testing cost, the advantage realizing multilayer abrupt test, will show
Write and improve Oil testing efficiency, reduce Oil testing cost.
In sum, content of the present utility model is not limited in the above embodiments, in same area insighted it
Scholar can propose other embodiments within technological guidance's thought of the present utility model easily, but this embodiment is all wrapped
Include within the scope of the utility model.
