Embodiment 1
[0032] Among them, such asfigure 1 As shown, the inner well pipe and the outer well pipe are composed of multi-section units, which are respectively: well pipe section unit, isolation section unit, wellhead unit and well bottom unit.
[0033] The well pipe section unit body in this embodiment is as follows figure 2 , including the inner well pipe section 1 and the mesh type well pipe section 5, both of which are coaxially fixed together by connecting pieces 6. One end of each inner well pipe section 1 is provided with a casing seat 2, and the other end is provided with a plug. Therefore, the inner well pipe section 1 between the adjacent well pipe section unit body and the well pipe section unit body is fitted together through the plug and the casing seat 2, and the adjacent mesh type well pipe section 5 is welded (or bolt or buckle). connected) fixed together. The water outlet pipe 17 is located in the well pipe after the inner assembly is butted. In this embodiment, the ...
Embodiment 2
[0041] Embodiment 3: On the basis of Embodiment 1, the well pipe unit is modified. like Figure 6 and Figure 7 As shown, plugs or casing seats 2 are provided at both ends of the inner well pipe section, and casing seats 2 or plugs are provided at both ends of the adjacent inner well section matched with it.
Embodiment 3
[0042] Embodiment 4: On the basis of Embodiment 1, the unit body of the isolation section is modified. like Figure 8 and Figure 9 As shown, plugs or casing seats 2 are provided at both ends of the inner well pipe section, and casing seats 2 or plugs are provided at both ends of the adjacent inner well section matched with it.
