Description

An adjustable coalbed methane detection and acquisition device Technical Field

[0001] This utility model relates to the field of coalbed methane exploration technology, and in particular to an adjustable coalbed methane detection and acquisition device. Background Technology

[0002] Coalbed methane, also known as coal mine gas, is mainly composed of methane (CH4). It is an unconventional natural gas stored in coal seams in an adsorbed state. The combustion products of coalbed methane are mainly water and carbon dioxide, with almost no other waste gases produced. Therefore, it is considered a clean energy source. There are two main methods for extracting coalbed methane: surface drilling and extraction through underground gas drainage systems. Due to the low permeability of coalbed methane, reservoir stimulation measures such as hydraulic fracturing are usually required to increase production. The coalbed methane extraction process includes three stages: drainage, depressurization, and gas production. As the pressure decreases, the gas production gradually increases, reaches its maximum value, and then begins to decline.

[0003] Existing coalbed methane detection and collection devices, such as the one described in application number CN202321602334.7 (which relates to the field of coalbed methane detection and collection devices), disclose an adjustable coalbed methane detection and collection device. This device aims to solve the technical problem that existing coalbed methane detection and collection devices are prone to wear against the wall of the well channel when entering the well, and that the collection port of the collection device is difficult to adjust quickly to move stably along the channel wall. This coalbed methane detection and collection device includes a collection tube and a fixing ring fixedly installed on the outer wall of the collection tube. However, the above-mentioned technology mainly collects samples through a set of collection ports, which can lead to mixed samples and affect the overall judgment of the fault. Therefore, this utility model proposes an adjustable coalbed methane detection and collection device to solve the problems existing in the prior art. Summary of the Invention

[0022] The Lianxin Tube 201 has a multi-cavity structure.

[0023] In this embodiment, when data collection is required, the pneumatic valve plug 206 is opened, allowing gas to be temporarily stored in the collection tank 203 through the side pipe 204 for effective data collection.

[0024] The positioning adjustment assembly 1 includes a positioning ring 101, a lower side frame 102, a lower movable bar 103, a mounting plate 104, a lower connecting plate 105, an upper connecting plate 106, an upper side frame 107, an upper movable bar 108, a movable wheel 109, and a hydraulic telescopic rod 1010. The lower side frame 102 is provided on the outer side of the positioning ring 101, and the lower movable bar 103 is bolted to the outer end of the lower side frame 102. The mounting plate 104 is provided below one end of the lower movable bar 103. The lower connecting plate 105 is bolted to the upper side of the lower side frame 102, and the upper connecting plate 106 is bolted to the upper side of the lower connecting plate 105.

[0025] In this embodiment, during use, the lower side frame 102 and the upper side frame 107 are bolted together by the bolt splicing of the lower connecting plate 105 and the upper connecting plate 106, so that the positioning ring 101 can be sleeved and connected to the connecting tube 201, and the equipment is placed at the processing location after the lower side frame 102, the lower movable bar 103 and the mounting plate 104 are connected.

[0026] An upper side frame 107 is bolted to the inner side of the upper connecting plate 106, and an upper movable bar 108 is bolted to the outer side of one end of the upper side frame 107.
