Description
Technical field
The utility model relates to a kind of steam raising plant in petroleum and natural gas drilling technology field, particularly a kind of drilling well Electrothermic steam generating means.
Background technology
China's 70-80 in last century age is because power tense Electrothermic steam device is prohibited from using.Until just start to occur domestic Electrothermic steam device the nineties in last century, more external advanced country hysteresis 30-40.Recent years, country strengthened environmental protective measure, and China's supply of electric power is abundant gradually, and one ton of following steam boiler of China makes the transition to Electrothermic steam generating means after having experienced coal burning boiler, thermo oil boiler.This type device is because of its environmental protection, essential safety, and operating cost, far below oil burning boiler, started to be used more widely in recent years.
Although the advantage of Electrothermic steam generating means is more, current northern cold zone, drilling well in winter is still widely used coal-burning boiler and oil burning boiler, and main cause is power tense several years ago, does not develop suitable electric heating type steam raising plant.The coal-fired steam generating means that current drilling well is used is traditional product, have advantages of that operating cost is relatively low, but environmental pollution is very serious, and occupation of land space is large, and recondition expense is high.Drilling well fuel-steam generating means, has the space of occupation of land little, and recondition expense is low, the advantage of mobile convenient transportation, but operating cost is very high, and environmental pollution is more serious.
Summary of the invention
Technical problem to be solved in the utility model is to overcome traditional fuel oil and the high problem of the serious operating cost of coal-fired steam generating means environmental pollution existing in background technology, and provide a kind of drilling well Electrothermic steam generating means, this drilling well Electrothermic steam generating means, can effectively reduce operating cost, improve safety in operation, eliminate the problem of environmental pollution that traditional fuel oil and coal-fired steam generating means bring.
The invention for solving the technical problem can reach by following technical solution: this drilling well Electrothermic steam generating means, comprise room body, in room body, be divided into water tank and workplace, on described workplace sidewall, have out vapour delivery port, workplace is built-in with body of heater, switch board, upper of furnace body is equipped with temperature-measuring port, relief valve port, venthole, delivery port, pressure tap, described temperature-measuring port, relief valve port, pressure tap is connected to electric contact thermometer by pipeline respectively, safety valve, electro connecting pressure gauge, venthole, delivery port is by steam outlet pipe line, water outlet pipeline is connected to out vapour delivery port, steam outlet pipe line, on water outlet pipeline, be connected to respectively gas outlet valve, outlet valve, sidewall of the furnace body is connected to electrothermal tube group, and sidewall of the furnace body connects automatic blowdown valve, manual blowdown valve by pipeline, described water tank is connected to body of heater by moisturizing pipeline, is connected to water compensating valve, small pump, atmospheric valve, check valve on moisturizing pipeline.
This drilling well mainly comprises power supply the principle and goes out vapour and water outlet principle by Electrothermic steam generating means principle.
Power supply the principle: by 5000KVA/6000KVA drilling well industrial siding, S11-500KVA/6KV/0.4KV transformer is powered, inducer for line outlet end of transformer is by six roots of sensation YC1*120mm
2low-voltage cable is the power supply of Electrothermic steam generating means, and package unit is realized defencive function, fully loaded and breaking function and automatic control function by switch board.
Steam supply and water supply principle: by drilling crew's water-tank lorry, be that device water tank adds water, open feed water valve, device is transferred to full load condition, by switch board start button, at this moment small pump is started working.When in body of heater, liquid level reaches the highest liquid level of setting, liquid level sensor is transferred to switch board by signal, and after signal processing module, switch board sends instruction small pump and quits work, and electrothermal tube starts grouping and starts simultaneously, and two groups of electrothermal tubes start 5s interval time.Now start, for water heating in body of heater, when water temperature surpasses 100 ℃, to start to form steam in body of heater, when in body of heater, steam pressure surpasses 0.45MPa, electrothermal tube quits work, and power down interval time is 2s.During steam supply, main steam valve is opened, closed water supply valve simultaneously, the outer air-supplying valve of device is opened, at this moment realize the steam supply work to situ of drilling well.During water supply, main steam valve is closed, open water supply valve simultaneously, the outer water supply valve of device is opened, now realize scene water supply work.This device supplies water and supplies water for pressurize, and utilizing principle is that when under normal pressure, water temperature surpasses 100 ℃, water exists with gaseous form, and because the pressure in body of heater maintains 0.25MPa-0.45MPa all the time, corresponding temperature is 140 ℃-150 ℃, and water exists with liquid form equally.When opening outlet valve, delivery port pressure becomes rapidly normal pressure, and the water of 140 ℃ gasifies very soon, forms gas-vapor mix, realizes pressurize and supplies water.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this drilling well uses Electrothermic steam generating means owing to adopting said structure, avoided environmental pollution coal-fired and that fuel-steam generating means discharge of noxious gases brings, and in running, do not need to use fuel, greatly reduce operating cost, realize pressurize air feed and water supply function in device use procedure simultaneously, realized left unguarded; Safe and reliable, workable.To oil field wellbore construction in winter energy energy-saving and emission-reduction, increase economic efficiency, realize the object of green drilling well, oil field development is had to profound significance.
