Embodiment
Should form by from hot jacket, clamp body 1, assembly set 2, adjusting sleeve 3, plug 5 and flexible gland 6 with the core holding unit of self-heating function: clamp body 1 is cylinder; Clamp body 1 is set with from hot jacket; Form by from hot jacket body 7, insulation matrix 8, heating wire 9, adhesive strip 10 and splicing tape 11 from hot jacket; From hot jacket body 7 for xsect is the cylinder of semi-circular shape; Insulation matrix 8 and heating wire 9 is provided with in hot jacket body 7; Insulation matrix 8 can prevent heat from distributing; Put forward high-octane service efficiency.
Preformed hole 12 is provided with on hot jacket body 7; Splicing tape 11 is fixed with on the side periphery of hot jacket body 7; The adhesive strip 10 corresponding with splicing tape 11 is fixed with on the opposite side periphery of hot jacket body 7.Splicing tape 11 and adhesive strip 10 can bond together when fitting mutually.
Clamp body 1 has pressurization pore 13; The inwall of pressurization pore 13 sandwich device body 1 is provided with internal thread.Assembly set 2 is arranged on the termination, two ends of clamp body 1 by internal thread.
In assembly set 2, screw thread is provided with adjusting sleeve 3 respectively; Flexible gland 6 is provided with in clamp body 1 between adjusting sleeve 3; During experiment; The size of experimentally rock core volume can regulate distance between two adjusting sleeves 3; Thus flexible gland 3 is full of by experiment rock core.
In the adjusting sleeve 3 at flexible gland 6 two ends, screw thread is provided with plug 5 respectively.Plug 5 one end extends in flexible gland 6, and plug 5 other end extends to adjusting sleeve 3 outer end; The plug 5 extending to adjusting sleeve 3 outer end is provided with handle 4.
Should with the core holding unit of self-heating function; During work, plug 5 is unloaded; Then by the endoporus of adjusting sleeve 3, experiment rock core 14 is loaded in flexible gland 6, then plug 5 is loaded onto; Subsequently, tighten plug 5, plug 5 will in the axial direction by the compacting of experiment rock core 14.
