According to the geologic features where the Sheng-li No.5 workover platform locates, the text states a jetting valve of leg shoe. The jetting valve could prevent from the jam of mud and sand when the platform leg shoe penetrates the seabed, so it is particularly applied to the muddy sea waters such as Bohai.
The 3-D RNG k - e numerical model of turbulence flow is built with FLUENT software. The mixture motions of water and sand, in the upper direction and side direction, are calculated. The results show that, the effect of jetting in upper direction is evident compare with the jetting in the side direction, under the condition of the same pressure and speed. It's easier to start suspending for the inside...
