Abstract: With improvement of drilling process technology, customers come up with higher and higher requirements on drilling fluid circulation manifold. On one hand, drilling fluid circulation manifold is required to have high pressure-bearing capacity. On the other hand, drilling fluid quality is required to be improved. By means of the computer 3D modeling technology, strictly verified calculation and repeated field experiments, the manufacturer independently developed the high-pressure drilling fluid circulation manifold losing less pressure of drilling fluid and allowing a high-quality passage of drilling fluid. Meanwhile, it standardized production process strictly according to the petroleum industrial standards and API standards, making the product a domestic leader in terms of technology. Field application indicated that this product was strong for its pressure bearing capacity, cost-effective, easy for installation, widely applicable and able to be used as a module matching with deep well drilling rig and complicated well.
