44 results about "Joint injection" patented technology

In medicine, a joint injection (intra-articular injection) is a procedure used in the treatment of inflammatory joint conditions, such as rheumatoid arthritis, psoriatic arthritis, gout, tendinitis, bursitis, Carpal Tunnel Syndrome, and occasionally osteoarthritis. A hypodermic needle is injected into the affected joint where it delivers a dose of any one of many anti-inflammatory agents, the most common of which are corticosteroids. Hyaluronic acid, because of its high viscosity, is sometimes used to replace bursa fluids. The technique may be used to also withdraw excess fluid from the joint.

Separate zone waterflooding technology policy limitation before reservoir water breakthrough

The invention discloses a separate zone waterflooding technology policy limitation before reservoir water breakthrough. The separate zone waterflooding technology policy limitation comprises the following steps of firstly, considering multiple factors comprehensively, establishing a series of injection-production well group typical models, then carrying out numerical simulation research of multi-layer joint injection on the models, taking the water breakthrough time level difference as the longitudinal equilibrium displacement criterion, and evaluating the longitudinal dynamic non-equilibrium degree before reservoir water breakthrough through the Lorentz coefficient; and finally, determining the separate zone waterflooding technology policy limitations before reservoir water breakthrough with different rhythmicity and different well pattern forms according to a Lorentz coefficient warning value. The separate zone waterflooding technology policy limitation before reservoir water breakthrough is more accurate, simpler and easier to operate, can provide the guidance for the division of the oil field on-site separate zone waterflooding technology policy limitations, so that the oil reservoir development effect is improved, and the oil reservoir recovery rate is increased.
