Problems solved by technology

[0002] When sampling in the downhole drilling site, sampling personnel are required to retest the included angle of the drilled hole. The traditional included angle measurement method is to use the center line of the roadway to place the vertical line, and then place a vertical line at the side of the roadway. Line, draw another vertical line between the two vertical lines, and then draw a straight line intersecting the three vertical lines to extend to the side of the lane to ensure that the middle perpendicular line and the side of the lane form a 90° angle, and then use After the slope gauge coincides with the 90° angle, pull out the angle required for drilling. This drilling retest method is cumbersome to operate, time-consuming and laborious, and it is not conducive to the downhole sampling personnel to quickly retest the drill angle.

Embodiment 1

[0023] Embodiment one: see figure 1 , in the figure, 1-vertical pole, 2-hanging hammer, 3-hanging wire, 4-first gradient gauge, 5-second gradient gauge, 6-guy wire, 7-third gradient gauge.

[0024] The quick auxiliary device applied to the re-inspection of the included angle in the drilling field, including three gradient gauges and the vertical pole 1, wherein: the upper end surface of the vertical pole 1 is welded and fixed to the lower surface of the second gradient gauge 5 center position, and the axis of the vertical pole 1 Perpendicular to the plane of the second slope gauge 5, the first slope gauge 4 and the third slope gauge 7 are respectively arranged on the pole 1, the first slope gauge 4 and the third slope gauge 7 are perpendicular to each other, and the second slope gauge 5 To form a vertical three-dimensional space model, a hanging wire 3 is respectively set at the central positions of the first gradient gauge 4 and the third gradient gauge 7, a hanging hammer 2 ...

Embodiment 2

[0027] Embodiment two: this embodiment is basically the same as embodiment one, and the similarities will not be repeated. The difference is that the first gradient gauge 4 and the third gradient gauge 7 are first welded together to form an assembly, and the assembly is then Welded on the pole 1, so as to ensure that the two slope gauges are vertical, reduce the difficulty of processing, and ensure the accuracy of the angle at the same time.

Embodiment 3

[0028] Embodiment 3: This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the first gradient gauge 4 and the third gradient gauge 7 are fixed together by right-angled positioning blocks to form a combination ( not shown in the figure), to ensure mutual perpendicularity, the assembly is then welded on the pole 1; the first slope gauge 4 and the third slope gauge 7 and the right-angled positioning block are fixed by welding or screws, according to It needs to be confirmed that it is connected by screws, can be disassembled, and is easy to adjust the angle.
