摘要： An offshore universal riser system may include a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device may releasably secure the valve module in the passage. A method of constructing a riser system may include the steps of installing the valve module in the passage, and installing at least one annular seal module in the passage. The annular seal module may prevent fluid flow through an annular space between the riser string and a tubular string positioned in the passage. Drilling methods may include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, may be dimensioned for installation through a rotary table.

摘要： An offshore universal riser system (OURS) and injection system (OURS-IS) inserted into a riser. The OURS/OUR-IS provides a means for pressurizing the marine riser to its maximum pressure capability and easily allows variation of the fluid density in the riser. The OURS-IS includes a riser pup joint with provision for injecting a fluid into the riser with isolation valves. The OURS includes a riser pup joint with an inner riser adapter, a pressure test nipple, a safety device, outlets with valves for diverting the mud flow, nipples with seal bores for accepting RCDs. The easy delivery of fluids to the OURS-IS is described. A method is detailed to manipulate the density in the riser to provide a wide range of operating pressures and densities enabling the concepts of Managed Pressure Drilling, Dual Density Drilling or Dual Gradient Drilling, and Underbalanced Drilling.
