Computing thermal conductivities of rocks from chips and conventional specimens

摘要: Suggestions are made for detecting minerals arranged in parallel rock specimens of the size commonly used thermal conductivity measurements. Methods proposed testing validity conductivities computed from composition a specimen various simple models. For system having only two conductivities, it is not necessary to know either conductivity; if there with three different one need be known. In both cases unknown mineral obtained tests, thus giving quasi situ value these minerals. The tests have been applied set 48 disks coarse-grained granite described an earlier paper. It was found that model could definitely discarded but difficult distinguish between dispersive (Maxwell) and series model. feldspar significantly higher biotite lower than previously supposed. application results computing chips oil wells, or friable cores, discussed.
