The present study is to investigate the discharge of drilling
muds and produced water from oil drilling platform.The results
can be used as references for marine environment protection.
The short-term diffusion of the discharge can be catalogued
into three phases:jet convective descent, dynamic collapse and
bottom encounter.By using the conservation laws,a set of
ordinary differential governing equations are derived.The set
of govering equations incorporating with proper initial
conditions are solved by the Forth order Runge-Kutta Method.The
variations of the discharged muds of their trace centerline
path and dilution rate are calculated and discussed.The
calculated trace centerline path of the discharge is in good
agreement with the experimental data of Davis et al.Also the
discharge radius is smaller as in comparison with Teeter''s
result.
