摘要： A method implemented using one or more computer processors for estimating the density of a material in an annular space includes receiving detector data representative of scattered photons resulting from interaction of a material in an annular space with radiation from a radiation source and detected by a plurality of radiation detectors. The method further includes performing a set of Monte Carlo simulations and generating polynomial models of the detector data based on the set of Monte Carlo simulations. The method further includes estimating the density of the material at one or more locations within the annular space based upon the polynomial models and the detector data.

摘要： A system for generating eccentering corrected response includes a logging tool configured to examine a material filled in an annular space to generate a tool response. The material is filled in an annular space formed by an outer conduit and an inner conduit disposed in the outer conduit. The logging tool is disposed in an inner conduit. The tool response includes scattered gamma ray photon counts distorted by a radial shift of the logging tool. The system includes a data transmission device coupled to a plurality of detectors and configured to transmit data detected by the plurality of detectors. The system also includes a computer processor linked to the data transmission device and configured to receive the tool response. The computer processor is configured to process the tool response and generate an eccentered corrected response by correcting effects of the radial shift in the tool response using eccentering correction technique.
