Abstract

The utility model relates to a bubble is arranged the gas production and is arranged the stick with the bubble, specifically is a stick is arranged to special bubble of low yield gas watered -out well, wherein: to steep row agent and make the cylinder row stick that vacuolates, and be provided with on the barred body of stick is arranged to the bubble and arrange the through -hole that excellent both ends face link up with the bubble. The utility model discloses because structure and the advantage that has are: the time of dissolving is short, the difficult shaft bottom of blockking up, the row's of making bubble gas production can be used at low yield gas watered -out well.

Description

Low yield air water floods the special bubble rod row of well

Technical field

The utility model relates to bubble mining gas bubble rod row, and especially a kind of low yield air water floods the special bubble rod row of well.

Background technology

Area, Chongqing of Sichuan is one of important neutralizing gas of China, but, wherein there is aqueous vapor to hide ratio up to about 80%, along with the carrying out of exploitation, water is invaded the effective exploitation to gas reservoir and is created tremendous influence, if not takeing effective measures, gas well water logging certainly will be caused, reduce gas deposit recovery efficiency.

At present, the main technique means that area, Chongqing of Sichuan has aqueous vapor to hide later development is draining gas production, and has defined to steep the technical system as representative such as row, gaslift, electric submersible pump. Wherein, bubble row [namely bubble row refers to foams drain] gas production is that a small amount of tensio-active agent is injected into well by one, foam is produced with mixing wastewater with air in well, reduce the slippage loss of air water two-phase nanubrium flowing, increase band water ability, thus with gas flow, water is carried to the technique of well head, because it is easy to use, cost is low, applied widely, and it is widely applied.

The conventional foam discharging agent that prior art adopts generally comprises several as follows:

1., its component is by mass percentage: AMONYL 380LC 40～60%, dodecyl sulfobetaine 5～25%, hexadecyldimethyl benzyl ammonium alkyl ammomium chloride 5～25%, surplus are water;

2., its component be by mass percentage: cocoyl amine CAB 25～40%, Sarkosyl L 20～30%, surplus is water;

3., its components in mass portion number is: sodium lauryl sulphate 10-15 part, alkyl glycoside accounts for 2-5 part, and AES accounts for 15-18 part, and sodium laurylsulfonate accounts for 20-25 part, and bio-surfactant accounts for 5-10 part, and water accounts for 27-48 part. Described AES is fatty alcohol polyoxyethylene ether sulfate, and described bio-surfactant is smooth by the lipid acid sorb of the glycerin fatty acid ester of mass fraction 30 parts, 20 parts, the polysorbate of 20 parts and the stearic acid of 30 parts form.

But, above-mentioned conventional foam discharging agent is in bubble drainage technique use procedure, it it is generally the bubble rod row being made into bar shape, then bubble rod row is dropped into low yield air water and floods in well by workman, due to self structure, regular just not the sinking to the bottom with air water complete reaction in well of bubble rod row, just causes in the course of time and adopts Gas well blocking, more cannot be applied to low yield air water and flood in well.

Practical novel content

It is short that the purpose of this utility model is to provide a kind of dissolution time, and the low yield air water not easily blocking shaft bottom floods the special bubble rod row of well.

The technical scheme adopted for achieving the above object is such, and namely a kind of low yield air water floods the special bubble rod row of well, wherein: foam discharging agent is made cylinder and forms bubble rod row, be provided with through hole through for bubble rod row both ends of the surface on the excellent body of bubble rod row.

The advantage that the utility model has due to said structure is: dissolution time is short, not easily blocks shaft bottom so that row's bubble gas production can be flooded well at low yield air water and applied, and reaches the energy and effectively utilizes.

Accompanying drawing explanation

The utility model can be illustrated further by the indefiniteness embodiment that accompanying drawing provides.

Fig. 1 is the structural representation that the utility model foam discharging agent makes bubble rod row.

Fig. 2 is the vertical view of Fig. 1.

In figure: 1, bubble rod row; 2, through hole.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Low yield air water in FIGS 1 to 2, figure floods the special bubble rod row of well, foam discharging agent is made cylinder and forms bubble rod row 1, be provided with through hole 2 through for bubble rod row 1 both ends of the surface on the excellent body of bubble rod row 1. In this embodiment, through hole 2 makes bubble rod row 1 increase with the contact area of long-pending liquid in long-pending liquid, increases bubble rod row 1 dissolution rate in long-pending liquid, it is possible to reach the object of bubble row's draining gas production fast; Foam discharging agent adopts the foam discharging agent containing citric acid, sodium bicarbonate, ammonium chloride, Sodium Nitrite composition, and the carbonic acid gas discharged in dissolution process and nitrogen stir long-pending liquid again, add that dissolution time is short, just can be applicable to low yield air water and flood well.

For adapting to the needs of different tolerance gas well, in above-described embodiment, it is preferable that: the cross section of described bubble rod row 1 is circular or Polygons, and the limit quantity of described Polygons is at least three.

Obviously, above-mentioned all embodiments are part embodiments of the present utility model, instead of whole embodiments. Based on embodiment described in the utility model, those skilled in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the category of the utility model protection.

In sum, owing to said structure dissolution time is short, shaft bottom is not easily blocked; The row's of making bubble gas production can be flooded well at low yield air water and applied, and has broken through the technical bottleneck that bubble this effective technology of row cannot be applied in low yield air water and flood in well.

Claims

1. a low yield air water floods the special bubble rod row of well, it is characterised in that: foam discharging agent is made cylinder and forms bubble rod row (1), the excellent body of bubble rod row (1) is provided with by through hole (2) through for bubble rod row (1) both ends of the surface.

2. low yield air water according to claim 1 floods the special bubble rod row of well, it is characterised in that: the cross section of described bubble rod row (1) is circular or Polygons, and the limit quantity of described Polygons is at least three.
