Description

Technical Field

[0001] This utility model belongs to the field of superhard materials technology, and in particular relates to a cavity structure for synthesizing eight high-performance petroleum composite sheets. Background Technology

[0002] High-performance petroleum composite sheets (i.e., diamond composite sheets for oil drilling) are ultra-hard composite materials made by sintering diamond micropowder and cemented carbide matrix under ultra-high pressure and high temperature conditions. They combine the extreme hardness of diamond with the impact toughness of cemented carbide and are the core cutting components of oil drill bits.

[0003] High-performance petroleum composite flakes require high-temperature and high-pressure synthesis, necessitating the use of a six-sided press. This process involves loading the raw materials for synthesizing the flakes into a synthesis block, placing the block into the synthesis chamber of the six-sided press, and then synthesizing it under high temperature and pressure according to a specified process. In existing technology, to ensure the temperature and pressure within the synthesis block, the six-sided press can only synthesize one or two high-performance petroleum composite flakes at a time. Increasing the number of flakes synthesized would result in insufficient pressure on each flake to meet process requirements, leading to low production efficiency and high production costs.

[0004] Therefore, there is an urgent need for a cavity structure for synthesizing eight high-performance petroleum composite sheets to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to overcome the existing technical problems and provide a cavity structure for synthesizing eight high-performance petroleum composite sheets.

[0006] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0007] A cavity structure for synthesizing eight high-performance petroleum composite sheets, the cavity structure comprising two synthesis blocks; each synthesis block comprising an insulating block with a cavity; an assembly structure disposed within the cavity of the insulating block; the assembly structure comprising a conductive steel cap, an insulator, a conductive sheet, a heating tube, a heat insulation sleeve, and a synthesis column;

[0008] The insulation jacket has a material hopper inside, which contains the synthesis column; a heating tube is fitted on the outside of the insulation jacket; conductive plates are installed at both ends of the heating tube; conductive steel caps are installed on the outside of the two conductive plates; and an insulator is filled in the space between the conductive steel caps and the conductive plates.

[0009] The synthesis column is surrounded by four cylindrical petroleum composite material bins at equal intervals.

[0010] The two synthesis blocks of this invention are symmetrically arranged in the synthesis chamber of a six-sided top press, with their opposite end faces in contact. In use, the two synthesis blocks are placed together within the synthesis chamber of the six-sided top press. Each synthesis block contains four cylindrical petroleum composite material bins, which are filled with raw materials for petroleum composites. Therefore, when using the six-sided top press for production, eight high-performance petroleum composites can be synthesized at once, significantly improving the synthesis efficiency and reducing costs.

[0011] Preferably, the insulating block is a pyrophyllite block.

[0012] Preferably, the insulating block is cuboid in shape with a side length of 97-105 mm; the cavity is cylindrical with a diameter of 83-91 mm.

[0013] Preferably, the insulating block is composed of two insulating blocks stacked one on top of the other; the height of the insulating block is 48.5-53mm, the cross-section of the insulating block is square, and the side length of the insulating block is 97-105mm.

[0014] Preferably, the conductive steel cap is made of No. 45 steel.

[0015] Preferably, the insulator is a dolomite insulator; the conductive sheet includes molybdenum sheets and carbon sheets stacked on top of each other, with the molybdenum sheets disposed on the outside of the carbon sheets; the heating tube is a carbon tube; and the insulation sleeve is a magnesium oxide insulation sleeve or a zirconium oxide insulation sleeve.

[0016] Preferably, the diameter of the petroleum composite material hopper is 14-21 mm and the height is 28-30 mm.

[0017] Preferably, the synthesis column comprises two synthesis columns arranged symmetrically at opposite ends; the synthesis column is a sodium chloride column or a carbon column.

[0018] Preferably, the synthetic single column is surrounded by four cylindrical petroleum composite material single compartments at equal intervals, and the petroleum composite material single compartments arranged symmetrically above and below form a petroleum composite material compartment.

[0019] The diameter of each petroleum composite material compartment is 14-21 mm, and the height is 14-15 mm. This invention restricts the structure of the composite block and the size of the insulating block. Only with this structure and size can eight petroleum composite sheets be placed simultaneously within the cavity. Furthermore, under this structure and size, the surfaces of the eight petroleum composite sheets can achieve a higher internal pressure, reaching 10 GPa, thus providing a foundation for obtaining high-performance petroleum composite sheets. Composite blocks of other sizes and structures cannot meet the conditions for synthesizing eight petroleum composite sheets at once and simultaneously achieving high internal pressure.

[0020] This utility model achieves the following beneficial effects:

[0021] This invention has a simple structure and is easy to operate. The cavity structure of this invention can achieve higher internal pressure, reaching 10 GPa, while synthesizing 8 petroleum composite sheets at one time. This greatly improves the synthesis efficiency of high-performance petroleum composite sheets and reduces the synthesis cost. Attached Figure Description
