Abstract
The utility model discloses a no rod-type along with pump sampler of hydraulic piston pump is applicable to all oil wells of adopting hydraulic piston pump to recover oil. The sample chamber has large volume and simple structure. A sample chamber is formed by connecting an upper piston and a lower piston with a sampling tube. The stratum produced liquid enters the sample chamber through the flow passage on the shunt joint and then flows into the hydraulic piston pump, so that the sample chamber becomes a necessary path for the stratum produced liquid to enter the hydraulic piston pump.
Description
The utility model relates to a kind of oil exploitation testing arrangement, and particularly a kind of hydraulic piston does not have rod-type with the pump sampler.Be applicable to the well that hydraulic piston pump recovers the oil.
At present, the hydraulic piston pump on-the-spot sampler that uses that recovers the oil is contained in the hydraulic piston pump afterbody, bottom and top several.But all there is following shortcoming to some extent: the operating procedure complexity, as well testing truck on the needs, following wire rope removes; It is big that repacking workload to the hydraulic piston pump configuration has been installed behind the sampler, and throw of pump shortens; Though the operating procedure that other has and simple to the repacking of hydraulic piston pump, again because of sampler self structure complexity, the piston type connecting rod switching mechanism of in specimen chamber, packing into, the open and close of control sampler are given to make to process and are brought difficulty.The volume of specimen chamber thereby dwindle.It is simple also to be badly in need of a kind of sampler self structure up till now, and the specimen chamber volume is big, the hydraulic piston pump sampler that the sampling operation construction is simple again.
The utility model is in order to overcome the shortcoming of above-mentioned hydraulic piston pump sampler, and the design a kind of simple in structure, the specimen chamber volume is big, and is easy and simple to handle, but placement force meter also in specimen chamber, the hydraulic piston pump that accomplish to take a sample, pressure measurement is carried out does not simultaneously have rod-type with the pump sampler.
Technical solution of the present utility model is: form this sampler with lifting appliance, joint, outer sleeve, tap and piston specimen chamber mechanism.For simplifying himself structure, strengthen the specimen chamber volume, changing existing piston type connecting rod switching mechanism is piston specimen chamber mechanism.Sampling tube and upper and lower piston are connected to form specimen chamber.Adorn a draining plug at the top of upper piston, be used for emitting the oil sample of specimen chamber.
The utility model is compared with existing sampler, the operation easy construction, and self structure is simple, and the specimen chamber volume is big, is easy to the processing assembling, and is cheap.In addition also can be in specimen chamber the placement force meter, under oil well output, the impregnable situation of hole condition, accomplish that sampling, pressure measurement carry out simultaneously.So both obtain real stratum and produced sample, improved operating efficiency again greatly.
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Fig. 1 is the structural representation of the utility model opening.
Fig. 2 is the structural representation of the utility model closed condition.

Referring to Fig. 1 and Fig. 2, hydraulic piston pump does not have rod-type with the pump sampler, is made up of lifting appliance (1), joint (11), outer sleeve (5), tap (8), spring (6) and piston specimen chamber mechanism.Outer sleeve (5) and joint (11) and tap (8) are linked and packed, interior dress piston specimen chamber mechanism.Piston specimen chamber mechanism is made up of upper piston (3), lower piston (7) and sampling tube (4), sampling tube (4) and upper piston (3) and lower piston (7) the formation specimen chamber that is linked and packed.Upper piston (3) and all have runner to be communicated with the runner and the hydraulic piston pump of tap (8) above the lower piston (7) makes the formation fluid sample sampler of flowing through earlier enter hydraulic piston pump (17) again, is real formation fluid sample thereby make the stratum of getting produce sample.Draining plug (2) is equipped with on the top of upper piston (3), is used for emitting the formation fluid sample in the specimen chamber.
Referring to Fig. 1 and Fig. 3, lifting appliance of the present utility model (1) also is the lifting appliance of hydraulic piston pump (17).
The lower end of tap (8) is connected with the upper cylinder half threading of water with piston pump (17), with hydraulic piston pump (17) from well head by power fluid through the oil pipe direct circulation above shaft bottom standing valve (20).When hydraulic piston pump (17) when starting working, because the power fluid pressure on the upper piston (3) of this sampler is greater than the discharge hydraulic coupling of the hydraulic piston pump that acts on lower piston (7) (17), and on, the ratio of lower piston sectional area is 1:1, so promote the piston specimen chamber mechanism of this sampler, the elastic force that overcomes spring moves down, the runner of lower piston (7) is communicated with runner (14) on the tap (8), the stratum production fluid promptly enters sampling tube (4) along the runner that has been communicated with, runner through upper piston (3) flows into annular space (13) again, runner (15) through tap (8) flow to the inlet valve (10) of hydraulic piston pump (17).The sampling tube (4) as long as hydraulic piston pump (17) work, stratum production fluid are just constantly flowed through, this sampler becomes the only way which must be passed of stratum production fluid.After hydraulic piston pump (17) quit work, the piston specimen chamber mechanism of sampler was by the elastic reset of spring (6), and runner (14) is closed.The stratum production fluid sample of being got in the sampler just can be circulated to well head through oil pipe by power fluid with hydraulic piston pump (17).Unload this sampler from hydraulic piston pump (17), unload lifting appliance (1), back out draining plug (2), just can emit the stratum production fluid of being adorned in the specimen chamber.
The respectively place of being tightly connected of the present utility model all adopts the sealing of " 0 " shape O-ring seal.Because encapsulating method is simple, so each parts of sampler are easy to processing, be easy to assembling, cheap.
