摘要：

A model is described that is capable of simulating in detail the time variation of formation pressures measured while drilling, in situations where supercharging is significant. Simulation results illustrate the variation of supercharging pressures with formation permeability, drilling-fluid-filtration properties, and drilling-fluid hydraulics. The model is used to explore how drilling operations influence the levels of supercharging when drilling two formations, widely separated along the well trajectory, and of significantly different permeabilities. The forward-simulation capability presented is believed to be a useful aid to the planning, understanding, and interpretation of formation-pressure measurements while drilling.
