Abstract: FIELD: oil and gas production industry. SUBSTANCE: this is used for geophysical investigation of wells and for checking technical state of their case-off, that is casing string and cemented ring in hole clearance and also pipe-compressor pipes lowered into well. According to method, lowered into casing string or into pump-compressor pipes is instrument with shortened measuring levers. Lower levers of them when lifted by means of springs are pressed against inner surface of string or pump-compressor pipes and their upper ends move along rheochord sliding contact or core in induction coil, thus creating surface adjustable variation of electric voltage in proportion to distance between lower ends of opposite measuring levers. Simultaneously recorded are changes of electric voltage which are proportional to intensity and spectrum of frequencies of bore-hole noises. These voltage changes are received from built-in body bottom-hole instrument converting acoustic oscillations into electric, and which is rigidly connected with upper ends of measuring levers which in this case function as waveguides from converter to casing string. Prevented is distorting influence of medium inside string on results of measured intensity and spectrum of bore-hole noises. EFFECT: high efficiency. 4 dwg

Abstract: FIELD: RUBBER INDUSTRY. SUBSTANCE: objective of invention is to reduce power consumption on liquefying cooling agent used when coagulating latex through freezing (by 10-14%); eliminate consumption of fresh softened water and heating agent for thawing coagulum with serum; diminish loss of fine rubber crumb; utilize main and side products of serum- containing water purification; and prevent environmental damage. Objective is accomplished by introducing additional freezing stage at superatmospheric pressure and specified rate of separating coagulum in hydrocyclone. Thawing coagulum with serum is effected using heat of vapors originated from decontamination of rubber crumb to remove residual monomers. Fine rubber crumb is concentrated in serum- containing water by means of self-purifying filter and returned into process. Filtrate is additionally purified on membrane by reverse osmosis technique and softened water is reused in the process of polymerization of monomers and concentrate of surfactants in building industry. Heat from latex under freezing is drawn off with low- boiling monomer first at superatmospheric pressure and rate of latex temperature drop 10-30 deg/h. Vapors of boiling monomer are separated from latex emulsion using centrifugal force in hydrocyclone. Frozen coagulum particles are separated from cooling agent in worm conveyor positioned at angle 30 deg. to horizon, whereas lower end of worm is located above the level of cooling agent in coagulator and on the outlet of worm there is hydraulic gate-separator. To thaw frozen coagulum with serum, heat of excess hot serum-containing water and of a part of decontamination vapors is utilized. Productivity of installation is increased by 28-40%.
