ESTIMATING IN SITU MECHANICAL PROPERTIES OF SEDIMENTS CONTAINING GAS HYDRATES

摘要

ABSTRACT A method for constructing elastoplastic property correlations in multicomponent particulate systems. The method includes obtaining parameters from geophysical data of a sediment-hydrate system, where the parameters include Shyd and pc and where Shyd is a hydrate saturation and pc is a confining pressure. The method further includes determining a Young's modulus (E) of the sediment-hydrate system using the parameters pjc and c is a scaling variable with dimensions of pressure. The method further includes adjusting a field operation based on the Young's modulus of the sediment-hydrate system. 512442 3 34
