The hydracyclone separating device in the process of drilling, such as desander, desilter play an important role in reducing the content of solid phase in drilling fluid, the separation effect drilling speed significantly.
desander
At present, the use of hydracyclone sand mouth are normal opening (directly outside the row), called open type hydracyclone. The separation effect of the hydracyclone is influenced by the size is quite large (especially the sediment diameter), and difficult to control.
Therefore, it has developed a new type hydracyclone can effective treatment of drilling fluid, can replace the desander, desilter and mini cyclone function,has a good effect of removing sand and mud.
Througth analysis of existing problems of the current use of solids control system, , it was put forward the improvement scheme of drilling fluid circulating system ground process, including the improvement and development of desander, drilling pump, water seal type cyclone separator. Also it can be expected, based on the existing research results, through the joint efforts of oil and solids control equipment production enterprise, the drilling fluid circulation system will be greatly simplified, the life of solid control treatment effect and use of equipment will be significantly improved, thus greatly improve ROP and reduce drilling costs.
