Description

A device is provided for taking samples of drillings from a borehole, a cololer, etc., of such types x G1; a sampling tube is inserted which you lower; lower: rnzol1 test liquid for children; in case of noMouii ig-coca in probeneries to. P |) and sampling, the needs should be lowered this time for the level of the liquid, which is not always possible. The largest dimensions and the associated with this circumstance are small: The permeability of the instrument well is the main disadvantage of the latter.

The proposed instrument has the distinctive feature that one or more vessels containing elastic chambers are included in the sampling tube, which are connected to the pump and are intended to supply a liquid tube to the sample receiver by creating pressure or vacuum chambers. Perforated tubes are placed inside the vessels, which serve as the liquid supply from the lower part of the vessel to the upper part during the operation of the chambers.

FIG. 1 shows a longitudinal section of the proposed device; in fig. Figure 2 shows a diagram explaining the use of a dual instrument in sampling from a great depth.

The hermetic metal vessel 2 contains inside the ger pilot tube 4 put on the metal-chesche pipe 4 and the perforated tube 5. The vessel 2 is made of a pipe section, hermetically closed on both sides with solders, and the upper 14: i bottom 3 metal plugs. The top tube 14 is hermetically sealed with a metal tube 4 n / a with a check valve.

As a device equipped to an utility, you grind the pump, the pump, the harbor;

If 2 times ;; over h;). t, sy, then sipcha,:; but but pipe 8 is pumped by air, whereby chamber 15 disperses and displaces air from the vessel 2, which goes to the surface through a check valve but tube 7. Then air Nz cameras 15 are released and, having driven the pump to the tube S, create a permit for this camera. Chamber 15 is diminished in vacuum 2, a vacuum is created, whereby water is supplied through the return clanan to the sampling tube 10. After this, chamber 15 is again pumped into tube 15 but air is removed from tube 8 and displaces the node 15 through the check valve and trubg; at 7 in nbonn znomnn with and pa new; | xnost. After releasing the air from chamber 15 and creating a vacuum in it, enova bass in the sea of water 15, which is then also displaced to the super-surface, etc., creating alternately pressure and depression in the chamber / 5, each time on the surface, - an 7 tube of water, corresponding to a change in the volume of the caller 15 with ethn operands. Thus, on the surface, we can: / get any amount of water needed to sample water from an inert gas. In this case, a thin stream of water comes out on the surface, the gas-bearing capacity of which can be easily investigated by methods known in geological exploration.

If the vessel 2 is under water, then the work on the exhaust of air from the chamber 15 is eliminated. It is only necessary to inject and release air through the tube 8, while the water in the vessel 2 will enter into force due to the pressure of its column rising above the vessel.

A perforated metal tube 5 serves to transfer the zodia from the lower part of vessel 2 to its upper part if chamber 15, having expanded, will block the path of water, having joined the walls of the upper part of the middle part of vessel 2.

The bottom of the vessel meter 2 can reach up to 15-20 mm (the dimensions of the rez-tube tubes, the grid, the load and the cable are still large). Therefore, the device can be lowered into the wells of any type, as well as into the well space of wells.

To inject air into 15 and create air in it; a vacuum can be used to pump the AO. MOVSKY pump, which gives the pressure to 4-7 and creates a full vacuum. When working with one vessel 2; South to select first in squas; where level and; water is in the city of biggs to 40-45. ;; from roverbost If the water level is r ;; ashes, then when working with such a pump you need: o add two lines

more vessels 2 and then, according to the same principle, first transfer water from the lower chambers to the upper chambers and from the upper chambers to the surface. In this case, the top will have to bring additional air tubes S from the lower vessel 2 (Fig. 2) for the two-vessel vessel. The effect of this device is understood from the foregoing and therefore is not described separately.

It is advisable to use rubber tubes in the structure of the walls of which rubberized mother is involved. Such tubes withstand more pressure and, moreover, they are not expanded. This fact is important for the sampling tube. If the tube is not stretched, water will be sucked from the depth corresponding to the length of the tube, the tube that stretches from the same can self-extend and then will not be matched} exactly in the accuracy of the water extraction depth. Therefore, if it is necessary to know precisely the depth of water withdrawal, then when working with a stretching tube, it is accompanied by a thin cable, to the end of which the same weight 12 is attached.

When working with the device, instead of rubber tubes, you can also use metal tubes.

Subject invention

. A device for sampling liquids from boreholes, wells, etc., with a sampling tube lowered by the lower shaft into the test liquid to be supplied with a pump to the sampler, so that it is supplied to The tube includes one or more vessels containing elastic chambers connected to the pump and intended to supply liquid with a sampling tube to the sample receiver by creating pressure or vacuum in the chambers.

2. The form of the device according to claim 1, characterized by the TGM, that inside the vessels is polyethylene perforated tubes that serve to supply liquid from the lower part of the vessels to the upper ones during operation of the chambers.
