摘要

Methods of processing diagrafias decay time to increase vertical resolution and increase the resolution of the measurement. A method of optimizing the resolution of the measurement is presented.In one implementation,The method includes (1) obtaining multiple samples of measurement in each of multiple positions along a boring hole; (2) to extract a sample of reference index of the set of samples to measureTion; (3) to determine a difference between each of the samples of reference index and corresponding index samples modelled; and (4) to update a set of samples of optimized index basedOn the difference.The samples of index are preferably selected to be representative of the samples obtained at each measurement position, and therefore, can be selected from the samples of measurement,Or alternatively, it can be the means of measuring samples.The samples of modelled above mentioned index can be determined from the application of a predetermined tool response to samples of optimized index, which, in turn,Can be determined by iteration.Since the difference has been reduced below some threshold value.The relationship between the samples of optimized index and the samples of reference index can be used to calculate the deconvolution filter for all the samples of measurement from originalThe boring hole. When applied to samples of the original measurement, the filter deconvolution produces samples of measurement having an optimized resolution.
