Methods and devices for analyzing and controlling the propagation of waves in a borehole generated by water hammer

摘要

A method for simulating water-hammer waves in a borehole is used to estimate formation parameters such as porosity and permeability, and to design completion strings. The simulation method uses a model that has a plurality of layers, at least one of the layers includes radial layering. Determined formation properties from analysis of the waterhammer are used in development operations.
