Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a shale gas development detection device that can perform stratified testing. Background Technology

[0002] Shale gas is an unconventional natural gas resource, primarily found in organic-rich shale. Compared to conventional natural gas, shale gas is characterized by abundant reserves and wide distribution, making it a crucial direction for future energy development. Currently, shale gas extraction mainly relies on production enhancement technologies such as hydraulic fracturing. While these technologies have increased shale gas production to some extent, they have also brought a series of problems, such as environmental pollution and high water consumption. Furthermore, accurate detection of gas composition and content is a critical aspect of shale gas extraction. Traditional gas detection methods often suffer from operational complexity and low accuracy, failing to meet practical needs. Developing a stratified shale gas extraction detection device is of great significance for improving the efficiency and safety of shale gas extraction. This device will help address many shortcomings in existing technologies and promote the development and application of shale gas extraction technology.

[0003] Shale gas, as an important unconventional natural gas resource, requires precise detection of gas at different levels during its extraction to ensure gas quality and safety. Traditional shale gas sampling devices are complex to operate and cannot perform stratified testing. The composition and content of shale gas at different levels may vary, and traditional devices cannot achieve precise detection of gas at different levels. Therefore, we propose a stratified shale gas extraction detection device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a shale gas exploitation detection device that can be used for stratified testing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stratified shale gas development detection device includes: an outer cylinder, a connecting pipe slidably installed inside the outer cylinder, sliders fixedly installed on both sides of the connecting pipe, a threaded plate fixedly installed on one side of each slider, a sliding strip hole matching the threaded plate on the outer cylinder, a fixed connecting block fixedly installed on one side of the outer cylinder, two motors fixedly installed on the fixed connecting block, threaded rods fixedly installed at the output ends of the two motors, the threaded plate being threadedly connected to the threaded rods, an installation block fixedly installed on one side of the connecting pipe, a micro pump fixedly installed on one side of the installation block, a sampling tube fixedly installed at the output end of the micro pump, a circular plate fixedly installed between the two sliders, a sealing ring fixedly installed on the circular plate, multiple exhaust pipes fixedly installed at the bottom of the outer cylinder, a collection and detection component provided at the bottom of each exhaust pipe, and a flow control component provided inside the installation block.

[0007] Preferably, the collection and detection assembly includes: multiple collection cylinders and a chromatograph; an upper connecting pipe is fixedly installed at the bottom end of each of the multiple exhaust pipes; a sealing ring is fixedly installed inside each collection cylinder, the sealing ring is sleeved on the outside of the upper connecting pipe; each of the multiple collection cylinders is fixedly connected to multiple upper connecting pipes; a control valve is fixedly installed inside each collection cylinder; a lower connecting pipe is fixedly installed at the output end of the control valve; the same transmission pipe is fixedly installed at the bottom end of each of the multiple lower connecting pipes; and the transmission pipe is fixedly connected to the chromatograph.

[0008] Preferably, the flow control component includes: a limiting disk and a worm gear, the worm gear being rotatably mounted in the mounting block, a rotating disk being fixedly mounted inside the worm gear, a plurality of round rods being fixedly mounted on one side of the rotating disk, a connecting rod being rotatably mounted on the round rods, a movable plate being rotatably mounted on one side of the slider, a plurality of arc-shaped sliding holes being opened on the limiting disk, and a plurality of round rods being fixedly mounted on one side of the rotating disk, the round rods being slidably mounted in the arc-shaped sliding holes.

[0009] Preferably, a second motor is fixedly installed inside the mounting block, a worm gear is fixedly installed at the output end of the second motor, the worm gear meshes with the bottom end of the worm wheel, a rotation groove matching the worm wheel is opened inside the mounting block, a limiting disc is fixedly installed on the inner wall of the rotation groove, and a mounting groove matching the second motor is opened inside the mounting block.

[0010] Preferably, a limiting block is fixedly installed on the outer cylinder, and both threaded rods are rotatably installed on the limiting block. The fixed connecting block and the bottom end of the limiting block are fixedly installed with the same bracket, and the bracket has a circular concave hole that matches multiple lower connecting pipes.

[0011] Preferably, the outer cylinder has a sliding groove that matches the slider, and a sealing block is fixedly installed at the top and bottom of the inner wall of the sliding groove, and the slider is slidably installed on the sealing block.

[0012] Preferably, a round rod three is fixedly installed on one side of the movable plate, the round rod three is rotatably connected to the connecting rod, and the movable plate is movably abutting against one side of the rotating disk.

[0013] In this invention, a shale gas extraction detection device capable of stratified testing is used. A motor drives a threaded rod to rotate, causing a threaded plate to slide a connecting pipe inside the outer cylinder. This allows the connecting pipe to move a mounting block, sampling tube, and micro-pump fixed to one side. The micro-pump extracts gas samples through the sampling tube, enabling sampling of gas at different depths. The gas is then drawn into a collection cylinder through the exhaust pipe and upper connecting pipe. Simultaneously, the movement of the connecting pipe moves two sliders, which in turn move a circular plate. The circular plate and sealing ring work together to ensure a seal between the connecting pipe and the outer cylinder after the connecting pipe moves, creating a seal inside the outer cylinder. This allows gas extracted from different depths to flow into different collection cylinders through different exhaust pipes and upper connecting pipes.

[0014] In this invention, a shale gas extraction detection device capable of stratified testing is described. The device collects and analyzes gas samples from different depths using a collection and detection component. An upper connecting pipe, sealing ring, control valve, lower connecting pipe, and transmission pipe work together to form a gas collection and transmission system. The collection cylinder, connected to the upper connecting pipe, collects gas samples from different depths and transmits them to a chromatograph for analysis. During operation, a worm gear mechanism driven by a second motor controls the rotation of the worm gear, thereby adjusting the flow rate of the sampling tube. A linkage mechanism consisting of a connecting rod, a moving plate, a first round rod, and a second round rod forms a linkage mechanism, allowing the moving plate to move and control the flow rate. This helps ensure the accuracy and representativeness of the sampling, thereby improving the efficiency and safety of the entire extraction process.

[0015] This utility model has a reasonable structural design. Through the cooperation of multiple structures, it can accurately control the insertion depth and position of the needle, and achieve effective collection of shale gas at different levels. Its structural operation process is simpler and more convenient, reducing the technical requirements for users. It can effectively improve the gas testing efficiency in the shale gas extraction process. The flow control component helps to ensure the accuracy and representativeness of the sampling, thereby improving the efficiency and safety of the entire extraction process.
