Abstract
The utility model discloses a sampling device for deep-well gas-liquid mixtures in an oil-gas field, which comprises a sampling cavity 1, a replacement cavity 2 and a timer 3 which are sequentially connected from bottom to top. A sampling hole 7 is arranged at the bottom of the sampling cavity 1, a piston 4 is arranged in the sampling cavity 1, the sampling cavity 1 and the replacement cavity 2 are connected through capillary tubes 5, and a releasing switch 6 is arranged on the capillary tubes 5. Starting time of a sampling process is automatically controlled by the mechanical timer, and course of the sampling process is controlled by the capillary tubes, so that gas and liquid of samples can be guaranteed to be free of any change during the sampling process. The sampling device for the deep-well gas-liquid mixtures in the oil-gas field solves a technical problem that samples obtained from the deep oil-gas field under the environment of high temperature and high pressure are closer to an original phase state, which has great significance in geological analysis.
Description
Technical field
The utility model relates to a kind of sampler of oil gas field deep-well gas liquid mixture, belongs to sampling technique field, oil field.
Background technology
In the sampling process of west, river oil gas field, because sample point locates below ground level more than 3000 meter, environment temperature is about 200 ℃, and pressure is about 80MPa.Can not use cable and battery.Existing sampling method cost is high, low, the consuming time length of efficient.Though available sampler type is a lot, all do not control the constant measure of phase, can not guarantee that the pressure and temperature of sample does not change, do not meet the instructions for use in oil field.
The utility model content
The purpose of the utility model is, a kind of sampler of oil gas field deep-well gas liquid mixture is provided.The sample that solution obtains under dark oil gas field high temperature and high pressure environment is significant to geological analysis more near original phase behavior.
The technical scheme of the utility model
A kind of sampler of oil gas field deep-well gas liquid mixture; Comprise the sampling cavity, displacement chamber and the timer that connect successively from the bottom to top, the sampling cavity bottom is provided with thief hole, is provided with piston in the sampling cavity; Sampling cavity is connected through capillary tube between the chamber with displacement, and capillary tube is provided with release-push.
In the aforesaid device, said capillary tube is made up of the fit clearance of accurate thread.
In the aforesaid device, said release-push and timer are in transmission connection.
In the aforesaid device, said timer is a mechanical timer.
Compared with prior art, the utility model is controlled the opening time of sampling process automatically through mechanical timer, and passes through the process of capillary tube control sampling process, guarantees that any variation does not take place for the gas of sample in the sampling process and liquid.Solved the sample under dark oil gas field high temperature and high pressure environment, obtained more near the technical problem of original phase behavior, geological analysis has been significant.

Being labeled as in the accompanying drawing: the 1-sampling cavity, 2-replaces chamber, 3-timer, 4-piston, 5-capillary tube, 6-release-push, 7-thief hole, 8-displacement liquid, 9-sample.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.
A kind of sampler of oil gas field deep-well gas liquid mixture, as shown in Figure 1.Comprise from the bottom to top the sampling cavity 1, displacement chamber 2 and the timer 3 that connect successively, sampling cavity 1 bottom is provided with thief hole 7, is provided with piston 4 in the sampling cavity 1, and sampling cavity 1 is connected through capillary tube 5 with replacing between the chamber 2, and capillary tube 5 is provided with release-push 6.Release-push 6 is in transmission connection with timer 3.Timer 3 is a mechanical timer.Capillary tube 5 can use the accurate thread fit clearance to substitute.
The course of work of the utility model and principle
As shown in Figure 1, before sampling, adopt conventional method to record the pressure data of sampling place earlier, in the sampling cavity 1 of sampler, charge into the displacement liquid 8 of uniform pressure then; The speed of going into the well and well depth according to sampler configure the opening time that timer 3 is confirmed the release-push 6 on the capillary tube 5 on the sampler.Sampler is put into sampling from aboveground, and the release-push 6 of capillary tube 5 is opened automatically, displacement liquid 8 in the sampling cavity 1 is got into through release-push 6 and capillary tube 5 slowly replace chamber 2; Get in the process in displacement chambeies 2 at displacement liquid 8, produce negative pressure in the displacement chamber 5, the piston 4 in the sampling cavity 1 is moved on slowly, sample 9 is sucked sampling cavities 1 with 0.1 liter/hour～1 liter/hour speed from thief hole 7.Said capillary tube 5 can adopt the fit clearance of accurate thread to substitute.
