Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a core logging scanning device. Background Art

[0002] Core refers to the cylindrical rock sample taken out from the hole using an annular core drill bit and other coring tools according to the needs of geological exploration or engineering. Core is an important physical geological data for studying and understanding underground geology and mineral conditions.

[0003] The purpose of coring is not only to discover oil and gas layers, understand the oil and gas content and reservoir characteristics, determine the basic data such as lithology, physical properties, thickness, area, etc., but also to establish stratigraphic profiles, study lithofacies and generation and reservoir characteristics, and understand the relationship between lithology and electrical properties to establish a physical property basis. At the oil and gas exploration site, an important daily task of core logging is to scan and analyze the core.

[0004] After the core is taken out of the coring barrel, it needs to go through a series of sorting work. The first is cleaning, which is to use clean water to clean the drilling fluid contaminants attached to the columnar core. However, for oil-containing cores, they only need to be wiped with a rag and cannot be rinsed with clean water. After cleaning, the cores that need or are suspected to have oil are placed under an ultraviolet fluorescent lamp to see if they have fluorescent display, and at the same time analyze and determine whether it is mineral fluorescence or crude oil fluorescence. Ordinary fluorescent lamps are a long rectangular metal box with a built-in fluorescent tube and an observation window on the outside. The main design purpose of this fluorescent lamp is to observe and analyze rock cuttings, but it is also used to illuminate cores in core logging.

[0005] At the construction site, fluorescent lamps need to be placed in the geologist's studio, because fluorescent observation requires darkroom conditions. This operation method determines that the core needs to be moved from the external site to the room. The size of the fluorescent lamp also limits the length of the core to be placed in. In order to change the core to fit the fluorescent lamp, usually a small section of the core is taken for observation. This operation method not only increases the workload but also destroys the integrity of the core, and it is seriously delayed in time.

[0006] In summary, there are several problems in core scanning and irradiation analysis based on conventional modes: intermittent manual operation is not conducive to scientific core irradiation scanning and is not convenient for immediate discovery of oil and gas displays; it occupies human resources and increases labor costs; the reciprocating movement of heavy cores is not conducive to occupational health protection; the inability to achieve automated operation is not conducive to the realization of standardized operations at the exploration site, which reduces the scientific and standardized work standards.

[0048] It should be noted that the directional terms or qualifiers "upper", "lower", "left", "right", etc. used in this application are all with reference to the drawings to which they are referred. They are not used to limit the absolute positions of the components involved, but can be changed according to specific circumstances.

[0049] Figure 1 The structure of the core logging scanning device 100 according to the present invention is shown. Figure 1 As shown, the core logging scanning device 100 includes a moving mechanism 1, a conveying mechanism 2 and a scanning mechanism 3.

[0050] The conveying mechanism 2 and the scanning mechanism 3 are both arranged on the moving mechanism 1. Under this arrangement, the moving mechanism 1 can drive the conveying mechanism 2 and the scanning mechanism 3 to move, thereby facilitating the movement of the core logging scanning device 100 outdoors.

[0051] like Figure 1 and Figure 2 As shown, the scanning mechanism 3 includes a cover 31 , which is buckled and arranged on the conveying mechanism 2 , and a scanning cavity 32 is formed between the cover 31 and the conveying mechanism 2 . A scanning tube 33 is arranged in the scanning cavity 32 , and a scanning mirror 34 is arranged on the cover 31 .

[0052] The conveying mechanism 2 is configured to allow the core to enter from one end of the scanning mechanism 3 and to move out from the other end of the scanning mechanism 3, so that the core can continuously pass through the scanning mechanism 3. Specifically, during the conveying process of the conveying mechanism 2, the core enters the scanning cavity 32 between the cover 31 and the conveying mechanism 2, and the scanning mirror 34 scans the core as the core continues to move.

[0053] In a specific embodiment, the chassis 11 is made of stainless steel or other load-bearing materials, and the chassis 11 is constructed in a rectangular parallelepiped shape with a length of 1400 mm×a width of 700 mm×a wall thickness of 3 mm.
