    摘要： An x-ray-based reservoir evaluation tool for the measurement of the shale density anticipated at shale-creep barrier within a cased borehole is disclosed, wherein the tool includes an internal length comprising a sonde section, wherein the sonde section further includes an x-ray source; a plurality of radiation measuring detectors; sonde-dependent electronics; and a plurality of tool logic electronics and PSUs. A method of using an x-ray-based shale-seal evaluation tool for measuring the shale density anticipated at shale-creep barrier within a cased borehole is also disclosed, the method including: using x-rays to illuminate the formation surrounding the cased borehole; using detectors to directly measure the density of the formation; using detectors to directly measure the effects on the measurement from tool stand-off or production liner attenuation; and compensating for the production liner and liner-annular region when computing the saturated formation density within the production interval.
