Description
Technical field
The utility model to relate in geological exploration and development core material analytical equipment field, is applicable to every physical parameter of large diameter core under simulant bearing conditions of coal seam and measures and carry out large diameter core experimental analysis research.
Background technology
Along with oil-gas exploration deeply and the progress of exploration engineering, Heterogeneous reservoir has become the zone of interest position of oil-gas exploration, and its reservoir has lithology, physical property, complex pore structure, the features such as strong nonuniformity.For these Heterogeneous reservoirs, the experimental result representativeness of Standard rock sample (diameter 2.5cm) is deteriorated, and large diameter core experiment more effectively can reflect the Geophysical Properties of Heterogeneous reservoir.
As the core analysis Research foundation equipment-core holding unit under reservoir conditions, form primarily of cylindrical shell, packing element, block head and potential electrode, its block head and cylinder internal diameter little, the rock core that can only meet Standard rock sample (diameter 2.5cm) uses, just helpless for large diameter core (diameter 9cm) analysis and research; And this kind of clamper is only confined to measure rock core resistivity under normal temperature and pressure, and there is measurement parameter single, the shortcomings such as test condition is limited, are having some limitations for inhomogeneous formation evaluation provides in parameter.Therefore, for providing more to Heterogeneous reservoir, more accurate petrophysical parameter, is necessary to develop a kind of large diameter core clamper can simulating reservoir temperature pressure, thus carries out large diameter core experimental analysis research further.
Utility model content
The utility model object is the shortcoming existed for prior art, temperature, pressure state residing for a kind of energy simulated formation rock is provided, under realizing reservoir conditions, the every physical parameter of large diameter core is measured, and carries out the High Temperature High Pressure large diameter core clamper of large diameter core experimental analysis research further.
Its technical scheme is:
High Temperature High Pressure large diameter core clamper, comprise cylindrical shell, packing element, block head and potential electrode, packing element is inserted in cylindrical shell, it is characterized in that: described block head is tubular structure, its internal diameter is not less than the internal diameter of packing element, the airtight annular space between cylindrical shell and packing element and the core chamber in packing element is formed after block head is connected with cylindrical shell two ends, the regulating block of hollow is equipped with in two block heads, two potential electrode are placed between regulating block and core chamber's upper and lower side respectively, cylindrical shell is provided with and is communicated in airtight annular space and outside pressurization interface, heating and heat-insulating device is provided with in the outside of cylindrical shell.
Such scheme also comprises:
The upper end of two potential electrode is all provided with built-in sonic probe, and described heating and heat-insulating device is at cylindrical shell outer disk after heater strip, and outer wrap has heat-insulation layer and shell.
