Description
Technical field
The present invention relates to oil field sampling technique fields, and in particular to one kind is for oil gas field deep-well gas-liquid mixture sampling dress
It puts.
Background technology
As the continuous breakthrough of oil-gas exploration technology, deeper and deeper oil-gas reservoir are constantly found and opened since " 95 "
It adopts, and is increasingly becoming construction of oilfield productivity and the primary position of upper production.As east SHENGLI PETROLEUM AREA Dongying, vehicle town were recessed in recent years
It falls into northern steep slope zone deep layer sand-conglomerate reservoir and has found nearly 20 oil gas field blocks such as Bin Nan, Sheng Tuo, salt man, well depth is more than
The exploration well of 4000m just has as many as 10 mouthfuls.
Prospect pit drill sampling analyzes the important part as investigation and prospecting, since sample point locates below ground level more than 3000
Rice, environment temperature is at 200 DEG C or so, and pressure is in 80MPa or so.Existing sampler can not ensure the pressure and temperature of sample
Do not change, it is impossible to really reflect sample point actual conditions, cause not meeting the requirement of oil field detection.
Invention content
In view of this, the purpose of the present invention is to provide one kind for oil gas field deep-well gas-liquid mixture sampler, solution
The technical issues of sample certainly obtained under deep oil gas field high temperature and high pressure environment is closer to original phase behavior.
In order to achieve the above objectives, the present invention provides following technical solution：
For one kind for oil gas field deep-well gas-liquid mixture sampler, the sampler includes a sampling tube body, described to take
Piston I and piston I I are from top to bottom respectively equipped in sample tube body, the sampling tube body is divided into sampling room, high pressure successively
Gas chamber and balance cylinder, the piston I I are equipped with filling channel, high pressure gas, the sampling room room are housed in the plenum chamber
Body is equipped with the sample inlet and sample channel that blend sample enters.
On the filling channel check-valves is equipped with close to one end of the plenum chamber.
The high-pressure drain plug for bearing high pressure is equipped on the filling channel close to one end of the balance cylinder.
The built-in high pressure gas of the plenum chamber is inert gas, such as helium, nitrogen.
The sample channel is equipped with shut-off valve.
Mobilizable sliding block is equipped in the sampling room.
The sampler top is connected with drilling rod used in probing.Further, the sampler with probing used in
Drilling rod is connected with screw thread.
The beneficial effects of the present invention are：
Compared with prior art, the compensation mechanism that gas-liquid mixture sampler of the invention passes through high pressure nitrogen, it is ensured that sampling
Any variation does not occur for the gas of sample and liquid in the process, solves the sample obtained under deep oil gas field high temperature and high pressure environment
The technical issues of closer to original phase behavior.
Description of the drawings
In order to make the purpose of the present invention, technical solution and advantageous effect clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is the device of the invention structure diagram.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this
It invents and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Fig. 1 is the present invention for oil gas field deep-well gas-liquid mixture sampler structure diagram.Sampling described in the present embodiment
Device includes a sampling tube body 1, and piston I I 7 and piston I 10 are from top to bottom respectively equipped with by institute in the sampling tube body 1
It states sampling tube body 1 and is divided into balance cylinder 6, plenum chamber 9 and sampling room 11 successively, the piston I I 7 is equipped with filling channel
3, the plenum chamber 9 is interior equipped with high pressure gas, and 11 chamber body of sampling room is equipped with the sample inlet that blend sample enters
13 and sample channel 5.
The present invention operation principle be：It goes into the well every time before sampling, pressure data at sampling is first measured using conventional method,
Then the high pressure nitrogen of relevant pressure is filled with into plenum chamber 9 according to the pressure data measured.Sampler reaches sampling position
It postpones, blend sample enters sampling room 11 by sample inlet 13 and sample channel 5, and sampling finishes sampler and above puies forward process
In, the high pressure nitrogen in plenum chamber 9 plays the role of pressure compensation, and constantly compensation causes to reduce since temperature and pressure reduces
Sampling room 11 in pressure so that any variation does not occur for sample gas and liquid in sampling room 11.In the sample channel 5
Shut-off valve 12 is equipped with, after sampler mentions ground, which is closed, can just ensure that 11 pressure are not in sampling room
It under damaed cordition, will be removed on drilling rod used in sampler from probing, the sampler and drilling rod screw thread used in probing
It is connected.Check-valves 8 is equipped with close to one end of the plenum chamber 9 on filling channel 3, external high pressure nitrogen enters high pressure gas
It will not be leaked behind room 9.It is equipped on filling channel 9 close to one end of the balance cylinder 6 and bears the high-pressure drain plug 2 of high pressure, it can be into
One step ensures that high pressure nitrogen will not leak.Movable slider 4 is equipped in sampling room 11, cushioning effect can be played, moreover it is possible to prevent
Piston I 10 pastes dead effect with sampling room 11.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.The equivalent substitute or transformation that those skilled in the art are made on the basis of the present invention, in the present invention
Protection domain within.Protection scope of the present invention is subject to claims.
