    摘要： A method and apparatus for predicting the performance of a drilling system for the drilling of a well bore in a given formation includes generating a geology characteristic of the formation per unit depth according to a prescribed geology model, obtaining specifications of proposed drilling equipment for use in the drilling of the well bore, and predicting a drilling mechanics in response to the specifications as a function of the geology characteristic per unit depth according to a prescribed drilling mechanics model. The geology characteristic includes at least rock strength. The specifications includes at least a bit specification of a recommended drill bit. Lastly, the predicted drilling mechanics include at least one of bit wear, mechanical efficiency, power, and operating parameters. A display is provided for generating a display of the geology characteristic and predicted drilling mechanics per unit depth, including either a display monitor or a printer.

    摘要： Shale plasticity in a geological formation is quantified by the steps of measuring a shale volume of the formation, measuring a shale composition of the formation, measuring a shale water content of the formation, and determining a measure of shale plasticity of the formation in response to the measured shale volume, shale composition, and shale water content according to a shale plasticity model. An apparatus for quantifying shale plasticity is disclosed also.
