Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
As shown in fig. 1 to 6, a gas lift reverse circulation drilling device 100 according to an embodiment of the present invention includes a slant hole base 10 and a power unit 20, and the power unit 20 is pivotally provided on the slant hole base 10.
Wherein, the inclined hole seat 10 comprises a lower seat 11, an upper seat 12 and an adjusting component 13. The lower seat 11 is provided with an opening for the bushing to pass through.
The upper seat 12 is provided with a first through hole 121 for the bushing to pass through, the upper seat 12 has a first end and a second end opposite to each other, and the first end of the upper seat 12 is pivotally connected to the lower seat 11.
A second end of the upper seat 12 and the lower seat 11 are connected by an adjustment assembly 13 for adjusting the pivoting angle between the upper seat 12 and the lower seat 11.
According to the gas lift reverse circulation drilling device 1000 of the embodiment of the invention, the upper seat 12 is pivotally connected with the second end of the lower seat 11, so that the upper seat 12 can rotate by taking the second end of the lower seat 11 as an end point, and an inclination angle is formed between the upper seat 12 and the lower seat 11, the first end of the upper seat 12 is connected with the lower seat 11 through the adjusting assembly 13, and the included angle between the upper seat 12 and the lower seat 11 is adjusted by adjusting the length of the adjusting assembly 13 (the length of the adjusting assembly 13 from the second end of the upper seat 12 to the lower seat 11). Wherein, the longer the length of the adjusting component 13, the larger the included angle between the upper seat 12 and the lower seat 11. Wherein, the included angle between the upper seat 12 and the lower seat 11 does not exceed 90 degrees.
It will be appreciated that when it is desired to perform a drilling operation in a sloped environment (a slope), the casing and the drill (a gas lift reverse circulation drill, etc.) need to be coaxial, it is necessary to adjust the length of the adjustment assembly 13 to make the drill mounted on the upper housing 12 coaxial with the casing. Wherein, the adjusting assembly 133 can be driven by a pneumatic cylinder, a hydraulic cylinder, a motor, etc.
Meanwhile, the power device 20 can be pivotally arranged on the inclined hole seat 10, and the included angle between the power device 20 and the inclined hole seat 10 can be adjusted, so that the height required for installing the drill rod 60 is reduced due to the fact that the power device 20 and the inclined hole seat 10 have a certain angle in the subsequent installation process, the drill rod 60 is convenient to install, and the installation height is reduced, and the construction safety is improved.
Therefore, the gas lift reverse circulation drilling device 1000 according to the embodiment of the invention has the advantages of simple structure, reduction of errors caused by the levelness of the installation surface, high safety and wide application range.
In some embodiments, the adjusting assembly 13 may be a telescopic rod driven by a driving device, a folding bracket, or the like.

According to the gas-lift reverse circulation drilling device 1000 provided by the embodiment of the invention, the power head 22 is pivotally arranged on the gantry 21, so that the subsequent installation of the drill rod 60 can be facilitated. Specifically, during operation of the gas lift reverse circulation drilling machine, the drill rod 60 first needs to extend into the drill hole, and a length of the drill rod 60 needs to be reserved between the power head 22 and the drill hole. When power head 22 is swingably mounted on gantry 21, power head 22 is rotated, and at this time, when a drill pipe is to be installed, the vertical distance between power head 22 and the drill hole can be determined according to the deflection angle of power head 22, and it can be understood that the larger the deflection angle of power head 22, the smaller the vertical distance required between power head 22 and the drill hole. Wherein the deflection angle of power head 22 is 1-90 degrees, preferably, the deflection angle of power head 22 is 45 degrees

According to the gas lift reverse circulation drilling device 1000 of the embodiment of the invention, the first auxiliary cross beam 214 can be connected with the driving device, so that the driving device can simultaneously control the first vertical column 211 and the second vertical column 212 through the first auxiliary cross beam 214 to adjust the angles between the first vertical column 211 and the second vertical column 212 and the inclined hole base 10, and simultaneously, the first auxiliary cross beam 214 can simultaneously control the first vertical column 211 and the second vertical column 212 to rotate at the same angle.
The stability of the structure between the first upright 211 and the second upright 212 can be further enhanced by the second sub-beam 215 and the third sub-beam 216, and the swing angle of the power head 22 can be limited by the second sub-beam 215 and the third sub-beam 216.
In some embodiments, the gantry 21 further includes a wear layer 217, the wear layer 217 being disposed between the first upright 211 and the main beam 213 and between the second upright 212 and the main beam 213, respectively.
