Embodiment Construction

[0007] Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which various embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0008] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0009] Reference attached figure 1 , In order to solve the problem of water accumulation in boreholes, the bottom drainage equipment for downhole drilling is specially developed, so as to realize the drainage of downhole water accumulation in downhole drilling under the condition of stop pumping and non-stop pumping, so as to ensure the drainage effect. The device consists ...

Abstract

The invention relates to a downward drilling hole draining device. The downward drilling hole draining device comprises a drainage system, a compressed air system and a draining system; the drainage system is formed by a drainage pipe and a control valve; the compressed air system is formed by an air injection pipe and a control valve; the draining system is formed by a draining pipe and a control valve. According to the downward drilling hole draining device which aims at solving the problem of water accumulation of a drilling hole, the water accumulation of the downward layer-penetrating drilling hole can be drained under the condition that drainage is stopped or not stopped and accordingly the drainage effect can be ensured.

Description

technical field [0001] The invention relates to a downward drilling drainage device, which belongs to the field of drainage. Background technique [0002] As we all know, drainage and slag removal are difficult during downward drilling. If the bottom plate is a water-bearing rock system, it will cause water accumulation in the borehole, resulting in loss of negative pressure and poor drainage effect. Contents of the invention [0003] The present invention relates to a downward drilling drainage device, the device includes the following structure: [0004] In order to solve the problem of water accumulation in boreholes, the bottom drainage equipment for downhole drilling is specially developed, so as to realize the drainage of downhole water accumulation in downhole drilling under the condition of stop pumping and non-stop pumping, so as to ensure the drainage effect. The device consists of three parts: one is the drainage system, which is composed of drainage pipelines ...
