Embodiment
The water pumping gas production tubing string that the utility model is provided, primarily directed to " prevent, harness the river " having in the development process of aqueous vapor field
Technique, its object is to realize gas field Active Drainage production, and can be monitored and controlled displacement size, subtract according to demand
It is slow to have water enchroachment (invasion) speed in the development process of aqueous vapor field, reach raising gas field recovery ratio purpose.
The water discharge technologies such as electric submersible pump, jet pump mainly are taken due to having both at home and abroad at present in the development process of aqueous vapor field, mainly
The gas well serious applied to mid-later development phase pit shaft hydrops, but it misses the optimal drainage period in gas field so that producing well is most
It is changed into gully eventually, it is little to whole gas field Protection significance.In addition, this scheme of prior art is only applicable to discharge exploitation
Hydrops in middle and later periods pit shaft, when there is an aqueous vapor field initial stage of development, when there is gas-liquid mixture in the oil pipe of pit shaft, using existing
The scheme of technology can not discharge the liquid in oil pipe, cause gas output efficiency not high.
Therefore, the water pumping gas production tubing string that the utility model is provided, it is contemplated that the need of gas field development gas and water at initial stage co-development
Ask, gas field Active Drainage production can be realized, so as to improve the gas recovery ratio in gas field.
The technical solution of the utility model is described in detail with specifically embodiment below.These are specific below
Embodiment can be combined with each other, and may be repeated no more for same or analogous concept or process in some embodiments.
The structural representation for the water pumping gas production tubing string embodiment one that Fig. 1 provides for the utility model.As shown in figure 1, the row
Hydromining tracheae post includes:Sleeve pipe 1, oil pipe 2, ball-and-seat 3, packer 4, gas lift valve 5 and christmas tree 9;
The oil pipe 2 is set in described sleeve pipe 1, and the ball-and-seat 3 is arranged on the end of the oil pipe 2, the gaslift
Valve 5 is fixed on the oil pipe 2 at the position of gas-bearing formation 7, is set in the annular space 6 between described sleeve pipe 1 and the oil pipe 2
There is the packer 4, and the packer 4 is located between the gas lift valve 5 and the ball-and-seat 3;
One end of described sleeve pipe 1 is fixed on water layer 8, the first valve 21 of the other end of described sleeve pipe 1 and the christmas tree 9
Connection, the other end of the oil pipe 2 is connected with the second valve 22 of the christmas tree 9, between described sleeve pipe 1 and the oil pipe 2
Annular space 6 and first valve 21 formation first produce passage, the ball-and-seat 3, the oil pipe 2 and second valve
Door 22 forms second and produces passage, described sleeve pipe 1, the gas lift valve 5, the oil pipe 2 and second valve 22 formation the 3rd
Produce passage.
Specifically, the oil pipe 2 and sleeve pipe 1 that are related in the present embodiment, it can be gas field edge straight well, inclined shaft, horizontal well
Completion tubular column, can also be that wet well in the production process of gas field turns the tubing string in gully, the present embodiment is not limited this
It is fixed.Shown in Figure 1, one end of above-mentioned sleeve pipe 1 is fixed on water layer 8, the other end of sleeve pipe 1 be located at well head and with well head
Christmas tree 9 is connected, and oil pipe 2 is set in sleeve pipe 1, and has annular gap between the oil pipe 2 and sleeve pipe 1, and packer 4 is arranged on
In the annular gap, to prevent the water of the intrusion of water layer 8 from entering in annular space 6.The end of oil pipe 2 is located at it of the packer 4
Under, and the end of the oil pipe 2 is provided with a ball-and-seat 3, the ball-and-seat 3 is check valve, it is ensured that the water that water layer 8 is invaded can only flow
To oil pipe 2, and it can not flow back.(the specific mounting means of gas lift valve 5 is provided with addition, being located in oil pipe 2 on the position of gas-bearing formation 7
May refer to shown in prior art), the fitting depth of the gas lift valve 5 is located on packer 4, that is to say, that from top to bottom, gas
Valve 5 is lifted to be located at topmost, next to that packer 4, followed by the ball-and-seat 3 of the end of oil pipe 2.
