Abstract
An underground sample collector, which comprises a rope socket 1, an attachment plug 2, a main body 3, a detonator 4, a cylinder 5, a connecting frame 6, an upper sealing ball 7, a spring 8, a clamping screw 9, an outer sleeve 10, a storing barrel 11, a lower sealing ball 12 and a protective cap 13. Because of the adopting of the structure that the attachment plug connected with the detonator is provided in the rope socket, the cylinder and the connecting frame are arranged on the detonator via sleeves, the upper sealing ball, the spring and the clamping screw are connected with the lower portion of the detonator, the connecting frame connects with both the outer sleeve and the protective cap, the storing barrel is arranged in the outer sleeve, and the upper sealing ball is arranged on the protective cap. The minimum external diameter of the sample collector is capable of reaching 25 millimeters, the minor external diameter makes the sample collector applicable to the sample collecting of all hole conditions, the sample collecting delay can be as long as half a year, and the sample collector is also capable of realizing multi-typed sample collecting such as the direct-reading tester sample collecting and the multi-parameter tester sample collecting and the like, which enables the testing and the sample collecting being proceeded simultaneously, enhances the accuracy and the instaneity of the sample collecting, and reduces the construction cost.
Description
Technical field
The utility model relates to the downhole tool that uses on a kind of oilfield, particularly a kind of downhole sampler.
Background technology
Oil well often need carry out well sampling in the Development and Production process, so that carry out physics, chemical analysis.Current downhole sampler is mainly based on the mechanical sampling device, and paddle type mill, top uncoupling type, clock machine formula, differential etc. are arranged.The mechanical type sampler is owing to structural reason, and external diameter is bigger, can only limit the scope of application of sampling in oil pipe the lower going-into-well.Though the clock controlled sampler can be realized delay sampling, be difficult to accomplish the time delay more than 120 hours.
The utility model content
The utility model purpose is to provide a kind of downhole sampler, and the external diameter of sampler is little, can go into the well from the oil jacket annular space.The control of sampling switch is determined by electronic clock, has prolonged the time delay of sampling greatly.
The utility model purpose is to realize like this, it is by rope socket (1), attachment plug (2), body (3), blasting machine (4), piston (5), link (6), last ball sealer (7), spring (8), holding screw (9), overcoat (10), storage tube (11), lower seal ball (12), helmet (13) is formed, rope socket (1) is connected with body (3), in rope socket (1), there is attachment plug (2) to be connected with blasting machine (4), on blasting machine (4), be with piston (5), link (6), the bottom is connected to ball sealer (7), spring (8), holding screw (9), link (6) and overcoat (10), helmet (13) connects, being storage tube (11) in the overcoat (10), is lower seal ball (12) on helmet (13).
During work, when sampler arrived the appointment depth selection, excitation signal arrived blasting machine by attachment plug and puts right gunpowder.Because the sealing function of sampler top connection and blasting machine holder makes sampling cock move down into the bottom of piston link; The opening of sampling cock moves down into the opening of piston link.Because the pressure of extraneous pressure in the storage tube, make sample around the sampler by last ball sealer, compression spring with tighten screw and enter in the storage tube.Because the storage tube is the sealing function by piston link, lower seal ball and helmet, can make pressure reach balance gradually after sample enters.At this moment spring return, last ball sealer make the sealing of storage tube, have finished sampling process.After sampling was finished, when mentioning ground on the sampler, by unscrewing play fixed screw and lower seal ball, sampling process was finished in the helmet liquid outlet taking-up that sample passes through to the pressure in the tube greater than the pressure on ground.
The utility model is having attachment plug to be connected with blasting machine in rope socket owing to having adopted, be with piston, link on blasting machine, the bottom is connected to ball sealer, spring, holding screw, and link is connected with overcoat, helmet, being the storage tube in the overcoat, is the lower seal ball on helmet.The sampling that realized going into the well in the oil well oil conduit is lowered to time-delay sampling under the pump with the holder tube.The external diameter minimum of sampler can reach 25 millimeters, and less external diameter makes it to be applicable to the sampling of any hole condition, can be from oil pipe, annular space lower going-into-well, and take a sample for a long time.The time-delay of sampler sampling can be for half a year, and this depends on the life-span of battery.Also can realize multiple modes such as the sampling of direct reading test instrument, the sampling of multi-parameters test instrument, the sampling of pump subiculum tube tester, test and sampling are carried out simultaneously, strengthen accuracy, the instantaneity of sampling, enrich content measurement, reduce construction cost.It is reasonable in design, and is simple in structure, is well suited for field popularization application.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in the figure, the utility model is made up of rope socket 1, attachment plug 2, body 3, blasting machine 4, piston 5, link 6, last ball sealer 7, spring 8, holding screw 9, overcoat 10, storage tube 11, lower seal ball 12, helmet 13, rope socket 1 is connected with body 3, in rope socket 1, there is attachment plug 2 to be connected with blasting machine 4, on blasting machine 4, be with piston 5, link 6, the bottom is connected to ball sealer 7, spring 8, holding screw 9, link 6 is connected with overcoat 10, helmet 13, being storage tube 11 in the overcoat 10, is lower seal ball 12 on helmet 13.
Claims (2)
1, a kind of downhole sampler, it is by rope socket (1), attachment plug (2), body (3), blasting machine (4), piston (5), link (6), last ball sealer (7), spring (8), holding screw (9), overcoat (10), storage tube (11), lower seal ball (12), helmet (13) is formed, it is characterized in that: rope socket (1) is connected with body (3), in rope socket (1), there is attachment plug (2) to be connected with blasting machine (4), on blasting machine (4), be with piston (5), link (6), the bottom is connected to ball sealer (7), spring (8), holding screw (9), link (6) and overcoat (10), helmet (13) connects, being storage tube (11) in the overcoat (10), is lower seal ball (12) on helmet (13).
