Inventor: MNATSAKANOV A V
IPC: E21B47/00
Filed: 1997-05-06
Granted: 1998-03-20
Abstract: FIELD: oil and gas production industry. SUBSTANCE: this can be used in drilling bore-holes and opening of productive beds. Device has receivers of pressure signals installed at well head, amplifiers for in-pipe and annular space lines, filters of in-pipe and annular space lines, threshold components, measurement control digital unit, time counter, unit for storing value of total time of spreading pressure pulses from well head to bottom hole and from bottom hole to well head (t i ), unit for calculation of difference in total time of spreading pulse pressures in controlled drilling mud and total time of spreading pressure pulses in primary drilling mud (Δt), unit for converting value Δt into voltage, unit of visual and audible signalling, indication unit Δt, recorder. In course of drilling, control is undertaken of gas inflow into well. Gas inflow into well is indicated by difference between t f  and t i  and Δt=t f -t i , that is Δt. Information about gas shows spreads at sound velocity and is recorded by ground surface receiving apparatus after several seconds. Value Δt > 0 is found at indication unit and recorded on diagram tape of recorder. At value Δt additionally switched on is visual signalling which attracts attention of operator by gas show in well. When Δt cr  reaches certain critical value, audible signalling is switched on. Visual signalling in this case continues operating. EFFECT: higher efficiency. 1 dwg

Abstract: FIELD: tunnel ventilation technology. SUBSTANCE: this relates to ventilation of underground mining workers and can be used for control of thermal conditions in railway tunnels located in regions with severe climatic conditions. According to method, outside air is delivered into tunnel due to action of piston phenomenon generated by moving transportation facilities and natural draft. Preliminarily, outside air is heated to above-zero centigrade temperature due to its mixing with tunnel air which is taken out from tunnel space where air temperature is above-zero centigrade. Tunnel air is directed to gantry of tunnel where ventilation air flow is coming in. Air flow quits tunnel through its opposite gantry. In this case, tunnel air is divided into two streams by means of ventilation gate which is installed in central part of tunnel. This ventilation gate partially closes tunnel bore when no transportation facility is moving through it. Part of tunnel air at gantry with outcoming air flow is taken out from tunnel and is heated to above-zero centigrade temperature for delivery to central part of tunnel. Here this air is mixed with second part of tunnel air at side of gantry with incoming ventilation flow. Application of aforesaid method reduces power consumption spent for heating air and simultaneously reduces probability of freezing of concrete lining over entire length of tunnel. EFFECT: higher efficiency. 1 dwg
