Research And Design Of Solid Control System Of 9000m Drilling Rig

Drilling fluid solid control system is important component of drilling rig,provided equipment and container for drilling fluid purification,circulation and reserve.This paper makes some design and research on 9000 m Drilling rig of Middle East area,mainly showed in process pipeline,equipment selection and structure design.The design of solid control system should be based on the drilling technology,not only can meet the maximum drilling displacement,but also can meet the maximum density drilling fluid.First,the process flow of solid control equipment purification,drilling pump suction,mixing pump suction and mixing pump discharge is designed.Second,the circulation displacement and system volume are calculated,the solid control system equips with desander & desilter,which are fit for unweighted drilling fluid.Also equips with two mud cleaners,which are available to weighted drilling fluid.Third,the drilling fluid tank and Big bag hoisting frame are analysed by Solidworks Simulation on strength and stability,research result shows the design of structure and material of the solid control system can meet requirement.Completed commissioning and acceptance activities of solid control system through water test and heavy mud test.The result proves that it can meet design requirement including equipment compatibility,drilling fluid tanks strength and process pipeline.Now,this solid control system has already put in use in Middle East.According to feedback,this rig is in good condition and meets expected design and the using requirements of rig site.In the process of designing and using the solid control system,the testing and feedback provide precious test data,and will provide design considerations for rig design in the future.
