The volume of drilling mud tank needs to be large enough to accommodate the maximum cycle volume of the drilling mud in the oil well drilling process, and have enough mud reserve capacity. At the same time the tanks also have the abilities of participating in cycle and controlling the oil well if an emergency sudden happen. In recent years, with the developing of the global markets and the increasing demand of drilling fluid solids control systems by drilling craft, the drilling mud tanks have the demand of increase the volume size.
If the drilling mud tank size increase, the cost of moving drill rig and drilling fluid will be increased as well. For this reason, reasonable cubage is the goal which pursued by end-users. According to the well drilling practice by many years in the past, it uses the method of calculation of drilled well hole cubage or drilled well casing cubage to calculate the effective cubic contains of the drilling fluid solids control system in general. The results of the two methods of calculation are estimated.
In a set of solids control system, the size of the single drilling mud tank and the amount of the cycle in the tank are decided by the height of the derrick substructure, the local transportation situation, and the effective treating volume of the drill rig needed and many other factors that will consider.
The top of the mud tank should have enough space to install needed solids control equipments, mud agitator and drill rig transfer pumps. Moreover, the settings of the associated flow line of the drilling mud, accessories, pump inhalation, water pipeline and the space of various equipments needs be considered. The volume of every storage mainly depend on the installation space of solids control equipments like shale shakers, desanders, desilters, decanter centrifuge, and other auxiliary equipments as well.
