Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, and in particular to a deep sampling device for shale gas exploration. Background Art

[0002] Shale gas refers to unconventional natural gas attached to reservoir rock systems dominated by organic-rich shales. It is continuously generated biochemical gas, thermogenic gas or a mixture of the two, and can exist in a free state in natural cracks and pores. Shale gas is usually stored in shale layers. During the exploration process, the shale layers need to be sampled and processed, so a deep sampling device is needed.

[0003] As for the current traditional sampling devices, most of them use drilling rigs to drill underground rock formations for sampling. However, during the sampling process, due to the presence of rock debris between the drill rod and the rock sample rod, the rock sample rod is retained inside the drill rod, so that when taking the rock sample rod, it is necessary to knock the drill rod to make the debris flow out and assist the rock sample rod to be discharged, so as to avoid the rock drill rod from breaking when taking it. At the same time, most drill rigs move straight up and down, resulting in the drill rig having to be laid down before it can be taken out after the sampling is completed. When the drill rig is too long, it is difficult to operate and it is inconvenient to perform sampling. Summary of the invention

[0004] The disclosed embodiment relates to a deep sampling device for shale gas exploration, which comprises a manual control part and a sampling part.

By arranging a delivery port inside the sampling rod, it is convenient to transport water, so as to facilitate the flushing of stone chips under the flow of water, and to facilitate the cleaning of stone chips between the sampling rod and the rock rod, so as to create a gap between the two, so as to facilitate the sliding out of the rock rod, thereby maintaining the integrity of the sample.
