The “PIK-RKT-160” X-ray core computer tomograph

The “PIK-RKT-160” X-ray tomograph for a full-size core is designed for qualitative and quantitative characterization of core density inhomogeneities. Tomographic analysis is necessary, first of all, for fractured-cavernous core study, when traditional petrophysics methods are ineffective.

The results of core tomographic study are logging of fractured and cavernous voids of a full-size core, cracks and caverns connectivity assessment, spatial orientation of planar elements (cracks, bedding planes, etc.), and in some cases it is possible to evaluate full-size core mineral composition. Core tomography is used to assess the condition of loose and poorly lithified core after its lifting and transportation (without opening containers), to select drilling location for standard and oversized samples to perform special core studies.

The tomography software makes it possible to visualize selected density inhomogeneities and perform their qualitative analysis. Tomography results (tomogram) are compatible with commercial software products for spatial data analysis (Avizo and others). The protective cabinet provides effective protection of personnel from tomograph x-ray radiation and eliminates the need to place the device in a separate room. Measurements can be taken without removing the core from receiver pipe or insulating tube.
