Description

Technical Field

[0001] The 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 is found in organic-rich mudstone and its interlayers and exists mainly in adsorbed or free states. It is mainly composed of methane and is a clean and efficient energy resource. The major resource-rich countries in the world have increased their efforts in shale gas exploration and development. The Jiaolai Basin in my country is located in the central part of the Shandong East Uplift. The shale gas-generating layer of the Shuinan Formation in the Jiaolai Depression belongs to the semi-deep, deep lake phase deposits in the stable sinking stage of the depression, with an area of ​​about 7,000 km. The Shuinan Formation was deposited at the peak of the development of the lake basin, 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 thickness of the deposited layer in the southeast is large, the lithology is fine, and it overlaps layer by layer toward the northwest, and the lithology becomes coarser. There are two sedimentation centers in the entire Jiaolai Basin, one is Shanqiandian and Shuinan areas in the Laiyang Depression, and the other is Wulian and Gaoze areas in 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 in a depression, the thickness and lithology of the Shuinan Formation are different, 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 supporting rods driven by supporting hydraulic cylinders, and the underground is drilled and sampled through the drill rods. 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 rods to lose their 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 failure of the sampling work, 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 easy to contaminate or even damage the drilling rig, and in the event of an accident, the drill rod cannot be quickly maintained.

[0038] In summary, the working principle of a geological environment sample sampling device based on basin shale gas resource investigation provided by an embodiment of the present invention is: 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 seats 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 supporting position collapses or other reasons cause insufficient supporting force, 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 to move downward through the multiple U-shaped frames 719, and the pull-down seats 701 are connected to the support seat 6. The pull 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 slide groove 706. At this time, the emergency support frame 703 rotates on the support shaft 711, and the reset torsion spring 712 is 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 urgently supported to avoid the collapse of the drilling rig fuselage 1. 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 blocked by the emergency support frame 703 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, and at the same time, the drive motor 905 is started to drive the drive gear 906 to rotate, and 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, scrapes off the mud around the drill rod 5, and discharges it through the mud cover 1003, and 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, so that multiple sound and light alarm lights 908 alarm, reminding the staff to take timely measures to avoid the occurrence of drilling accidents caused by excessive displacement; Furthermore, when the rotating ring gear 904 rotates, the pushing rod 1006 is synchronously driven 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 is reset under the rebound force of the rotary torsion spring 1009, so that the swing cover 1001 swings back and forth, and then the mud is thrown out, which can not only realize the discharge of the mud, but also avoid the accumulation of mud through the principle of swinging inertia.
