Design And Modification For The 300ft Jack-up Mud System

As the development of the oil exploration on land has been saturated,people have distracted their attention to the osean.The exploration in the osean is developing at a high speed like the mushroom after rain.However,the oil spilling in the Gulf of Mexico makes people more and more pay attention to the marin oil exploration's effect on the sea.Reducing price of oil also makes people control the expense strictly.The mud system is one of the most important systems of the marine jack up.The full usage of mud system can increase the drilling speed,decrease cost,reduce the well accidents,and protect the environment especially.The mud system can purify the mud coming from the well,reduce the cost and control the happening of well spilling and blowout.It determines the safety of jack up.Therefore the producer pays a lot of attention to the system design.They often talk with the shipowner to modify the mud system design from time to time.And adopt the positive suggestions.They try their best to meet the shipowner's requirement and improve the design.The modification of mud system can greatly increase the drilling performance and quality of the whole jack up and make sure of the safety working.This article describes the mud processing classification and function and the mud system design of jack up in detail.And it modifies the design according to the feedback.Moreover,it generally describes the application effect of the modified system.This article refers to the current international specifications and conventions to start the basic design.It uses the computer softwares to assit relevant design.Generally consider the actual usage in the site and modify part of design.Then apply it back to the site to check the usage effect.This article has finished the mud system design of 300 ft jack up.It has improved the former design with combining the actual experience.The research can be some kind of reference for the subsequent design of jack up.
