Granted: 2021-05-11
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for treating a medial meniscus injury without reaching an articular surface bordering on the joint cavity. Method involves a preliminary examination with MRI of the injured region of the joint, determination of a degenerative meniscus adjustment zone and introduction of a therapeutic composition stimulating the restoration of the damaged tissue in the area of injury. Therapeutic composition used is a platelet-derived mixture obtained from intrinsic blood, which, under ultrasonic control, is delivered into the degenerative meniscus adjustment zone by transcutaneous insertion of the needle into the meniscus thickness produced from the popliteal fossa. Therapeutic composition is administered until filling the whole volume of the damaged meniscus tissue. Therapeutic composition can also be introduced directly through the posterior surface of the joint into the meniscus and into the border zone of the capsule at a point closest to the posterior horn of the medial meniscus. Thrombocyte mixture can be administered in amount of 0.5 ml. When the needle is removed, 0.5 ml of a platelet mixture is added to the border zone of the joint capsule, and the platelet preparation is introduced with a puncture needle. Filling of the affected area with a drug is carried out from the centre of the area to its periphery. 
     EFFECT: method provides efficiency and safety ensured by manipulations only in the area of joint damage and using patient's own blood.

Abstract: FIELD: oil and gas industry.SUBSTANCE: invention relates to production of hard-to-recover oil and gas condensate reserves. Method involves pumping two fringes - before and after pumping of carbon dioxide into production well. When implementing gas-cyclic injection of carbon dioxide at supercritical conditions - temperaturemore than 31.1°C and pressure of more than 7.38 MPa, pumping of the first fringe is provided to the tubing string of the production well in the form of a reagent containing a surfactant. Then, a solid foaming agent is dosed and dissolved in the liquid contained in the well bore for at least 3 hours. Further, carbon dioxide is pumped under supercritical conditions. Prior to impregnation period, second rim is pumped. Its injection involves pumping to the production tubing string a composition containing a mixture of a corrosion inhibitor and a reagent containing a surfactant. Then, a solid foaming agent is dosed and dissolved in the liquid contained in the well bore for at least 3 hours. After that, the well is closed for the period of impregnation with subsequent extraction of oil from the same production well. First rim is used to inject the ML-super reagent containing the surfactant into the well tubing string to the wellhead. Then, hard foaming agent rods are introduced at rate of 0.2-0.5 kg per 1 m3of liquid, taking into account the volume of the tubing string for dissolution in the wellbore, and as second fringe is pumped mixture of corrosion inhibitor grade "Inkorgaz-21T-A" and reagent containing surfactant, grade "ML-super" in established ratios and in volume sufficient for filling of tubing string of well, as well as at rate of 1-5 m3per meter of the perforated interval of the treated header depending on the permeability of the collectors. Then solid foam maker rods are introduced at 0.2-0.5 kg per 1 m3of liquid taking into account volume of tubing string for dissolution in the well shaft.EFFECT: increasing extraction of hard-to-recover oil reserves with reduced content of water and gas condensate due to use of liquid carbon dioxide and foam systems.1 cl, 3 ex
