The centrifugal pump and jet mixers produced by TR Solids Control are applied in the drilling of CNOOC. Centrifugal pump feature stable output and wear-resistant sealing performance. It provides a brand-new solution for drilling fluid preparation. Centrifugal pump effectively enhanced the efficiency of jet slurry mixing and reduced the on-site operation and maintenance costs. TR Centrifugal pump have been widely recognized by industry customers.
The centrifugal pump used in combination with jet mixer has multiple core advantages.
Firstly, Centrifugal pump stably outputs pressure of 0.25 to 0.4MPa, driving the fluid to form a high-speed jet through the nozzle. Ensure that sufficient negative pressure is generated to efficiently draw in drilling materials such as bentonite, barite and polymers. The problems of insufficient material suction and uneven mixing have been solved.
Secondly, Centrifugal pump has excellent wear-resistant and sealing performance. The flow-through components are made of wear-resistant alloy cast iron. The impeller is designed as a semi-open type, suitable for harsh working conditions such as sandy slurry. Combined with a high-wear-resistant hard alloy double sealing system, it effectively prevents mud leakage.
Thirdly, it has strong adaptability and interchangeability. It can be matched according to the processing capacity of different jet mixers. Support interchangeability with Mission sand pumps. Significantly reduce the spare parts procurement and inventory costs for customers.
The performance of TR Solids Control centrifugal pump is outstanding. In certain ZJ70 drilling rig solid control system project, configuration scheme of parallel drive of dual jet mixers by dual TR centrifugal sand pumps was adopted. TR Solids Control has achieved a batching speed of ≥100kg/min, meeting the rapid weighting requirements of high-density slurry. The efficiency of drilling fluid performance regulation has been increased by more than 30%. The operation cost of a single well has been reduced by approximately 25%.
