Description

Technical Field

[0001] The present invention relates to the technical field of geological sampling devices, and in particular to a geological environment sample sampling device based on basin shale gas resource investigation. Background Art

[0002] Shale gas refers to unconventional natural gas that exists in organic-rich mudstone and its interlayers, and mainly exists in adsorbed or free states. It is mainly composed of methane and is a clean and efficient energy resource. The world's major resource-rich countries have increased their efforts in shale gas exploration and development. my country's Jiaolai Basin is located in the central part of the eastern Shandong uplift area. The shale gas-generating layer of the Shuinan Formation in the Jiaolai Depression is a semi-deep, deep lake-facies deposit during the stable subsidence stage of the depression, covering an area of ​​about 7,000 km. The Shuinan Formation was deposited during the heyday of lake basin development, with a large water area, a wide sedimentary range, fine lithology, and rich organic matter in the sediments. The ancient topography of the depression is high in the northwest and low in the southeast. The deposited layer is thick in the southeast and has fine lithology. It overlaps layer by layer toward the northwest and becomes coarser. The entire Jiaolai Basin has two subsidence centers, one is the Shanqiandian and Shuinan areas of the Laiyang Depression, and the other is the Wulian and Gaoze areas of the Zhucheng Depression. These two sedimentation centers control the distribution and changes of the gas-generating layer. Due to the segmentation of small terrestrial depressions, even within a depression, the thickness and lithology of the Shuinan Formation vary, and the gas-generating capacity is also different.

[0003] However, when investigating the distribution of shale gas, it is necessary to use a drilling rig to drill and sample the bottom layer. During drilling, the drilling rig is supported by a supporting hydraulic cylinder to drive the supporting rod, and the underground is drilled and sampled through the drill rod. However, due to the complex construction conditions in the field, when supporting the drilling rig, especially in relatively humid areas, it is very easy for the supporting rod to lose its supporting force due to the settlement of the ground supporting the drilling rig, and then the entire drilling rig collapses, which not only easily causes the sampling work to fail, but also easily causes damage to the drilling rig. In addition, a large amount of mud will accumulate around the drill rod during drilling and splash onto the drilling rig, which is very likely to contaminate or even damage the drilling rig. In addition, in the event of an accident, the drill rod cannot be quickly maintained. Summary of the Invention

It should be noted that in the embodiment of the present invention, when the swing arm 1004 rotates, it rotates on the mounting shaft 1005 through the torsion groove 1008, causing the rotary torsion spring 1009 to be stressed. When the rotating rod 1006 continues to rotate, it disengages from the swing arm 1004. At this time, the rebound force of the rotary torsion spring 1009 resets the swing cover 1001, causing the swing cover 1001 to swing back and forth. The swinging of the swing cover 1001 further achieves the purpose of throwing out the mud.

[0065] In summary, the working principle of the geological environment sampling device based on basin shale gas resource investigation provided by the embodiment of the present invention is:

[0066] When the drilling rig body 1 is drilling and sampling, multiple support rods 3 are extended to lift the drilling rig body 1. At this time, the support seat 6 is squeezed and the pull-down spring 722 is driven to be stressed. At this time, the multiple pull-down seats 701 and the connecting seat 702 are sleeved on the support rod 3, and the multiple locking bolts 717 are tightened so that the multiple connecting seats 702 are locked on the support rod 3, and the pull-down seat 701 is connected to the support seat 6 through the multiple U-shaped frames 719; it should be noted that if the support position collapses or the supporting force is insufficient for other reasons, causing the support seat 6 to lose support, at this time, under the rebound force of the pull-down spring 722, the support seat 6 moves downward, and drives the multiple pull-down seats 701 downward through the multiple U-shaped frames 719, and the pull-down seat 701 is connected to the support seat 6. The pull-down rod 721 moves vertically in the pull-down groove 720, and the pull-down seat 701 moves to drive the pull-down plate 707 to move. The pull-down plate 707 drives the adapter plate 708 to move through an adapter shaft 709. The adapter plate 708 drives the linkage plate 705 to move through another adapter shaft 709. The linkage plate 705 moves to drive the emergency support frame 703 to rotate. At the same time, the linkage plate 705 slides in the sliding groove 706. At this time, the emergency support frame 703 rotates on the support shaft 711 and causes the reset torsion spring 712 to be stressed, so that the emergency support frame 703 is supported by the auxiliary support seat 704, so that the support area is expanded by multiple emergency support frames 703, and the drilling rig fuselage 1 is provided with emergency support to prevent the drilling rig fuselage 1 from collapsing.

[0067] Furthermore, when the emergency support frame 703 rotates, the two limit rods 714 are no longer restricted. At this time, under the rebound force of the two rebound springs 715, the two limit rods 714 are extended, and the emergency support frame 703 is blocked to ensure the stability of the support of the emergency support frame 703. In addition, when the drill rod 5 is drilling, the mud is blocked by the mud cover 8 to prevent the splash of mud from causing pollution to the equipment or the environment. At the same time, the drive motor 905 is started, thereby driving the drive gear 906 to rotate. The drive gear 906 drives the rotating ring gear 904 to rotate, so that the rotating ring gear 904 drives the detection and cleaning scraper 902 to rotate through the follower rotating plate 901, scraping the mud around the drill rod 5 and discharging it through the mud cover 1003. If the drill rod 5 has a large displacement, the drill rod 5 squeezes the detection and cleaning scraper 902 to move and triggers the alarm switch 907, thereby causing multiple sound and light alarm lights 908 to alarm, reminding the staff to take timely measures to avoid the occurrence of drilling accidents caused by excessive displacement.

[0068] Furthermore, when the rotating ring gear 904 rotates, it synchronously drives the pushing rod 1006 to rotate, and the pushing rod 1006 drives the swing rod 1004 to rotate through the pushing wheel 1007, and the swing rod 1004 drives the swing cover 1001 to swing. At the same time, the swing rod 1004 rotates on the mounting shaft 1005 through the torsion groove 1008, and the rotary torsion spring 1009 is subjected to force, and when the pushing rod 1006 continues to rotate, it is disengaged from the swing rod 1004. At this time, the rotary torsion spring 1009 resets it under the rebound force of the rotary torsion spring 1009, and the swing cover 1001 swings back and forth, thereby throwing out the mud, which can not only discharge the mud, but also avoid the accumulation of mud through the principle of swinging inertia.

[0069] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
