2, watering quantity control is extensive, energy consumption is large: watering quantity carries out Artificial Control adjustment by front inspector, because adjustment cycle is longer, causes extensive management, increases energy resource consumption.
3, in practical application, the high-temperature water of a terminal heating furnace heating is responsible for tens mouthfuls of even more oil well watering companion heat, and every front inspector is responsible for several mouthfuls of wells, because front inspector worries that own responsible oil temperature is too low, often tune up watering quantity, like this, after the watering quantity of part oil well tunes up, cause the high-temperature water flow of terminal heating furnace output to increase, pressure decreased, and due to the increase of flow, the reduction of water mixing temperature will be caused again, affect the temperature of well mouth of oil well, pressure, cause temperature in pipeline, the fluctuation of pressure, cause more serious consequence.
4, automatic improving difficulty is large: existing metering room situation complexity, if wired temperature, pressure transmitter measurement returning-oil temperature and pressure are installed, due to needs cable wiring manufacture, need to stop work, thus impact production, and investment is large, the implementation cycle is long.

Radio temperature sensor node, wireless pressure sensor node, wireless automatic control water doping valve, backbone network gateway is arranged on production wellhead, measure returning-oil temperature at well head, return pressure and water mixing pressure, be pooled to center-controlling computer by backbone network gateway, in the time that returning-oil temperature is not within the scope of the best returning-oil temperature of setting (normally 35 to 38 degrees Celsius of best returning-oil temperatures), center-controlling computer is according to corresponding relation, calculate valve opening angle numerical value (watering quantity) and send to backbone network gateway, backbone network gateway sends to wireless automatic control water doping valve by wireless sensor network technology by opening angle numerical information, wireless automatic control water doping valve regulates watering quantity according to opening angle numerical information, until returning-oil temperature reaches the optimum state of setting.Certainly, operator on duty also can be according to returning-oil temperature, and Long-distance Control regulates watering quantity, and does not use automatic control and adjustment function.Implement scene at some, returning-oil temperature, watering quantity corresponding relation also can be placed in backbone network gateway or any intra-node, regulate at the scene watering quantity, and do not need to transmit back center monitoring computer.
In the present embodiment, radio temperature sensor node, wireless pressure sensor node can use supports the matured product of wireless sensor network technology, according to coverage requirement, forms the topological structures such as point-to-point, star-like, tree-like, mesh network.In some cases, radio temperature sensor node, wireless pressure sensor node also can be integrated together, and common enclosure, processor and wireless communication module are measured temperature and pressure simultaneously.
Wireless sensor network is accessed backbone network by backbone network gateway, comprises existing public network or private networks such as being singly not limited to GSM, CDMA, WIFI, WIMA, MCWILL, local area network (LAN), optical fiber.
Center monitoring computer can be arranged on the Surveillance center at different levels such as metering room, office, ore deposit portion, factory department, oil field general headquarters, also can arrange, and classification is by rights management simultaneously.
Wireless automatic control water doping valve can, on existing valve, install electric actuator additional, receives control command, the opening angle of control valve by wireless sensor network module.In practical application, wireless automatic control water doping valve also can become one electric actuator, wireless sensor network module, control circuit, valve.
The on-the-spot erection unit of the oil recovery such as radio temperature sensor node, wireless pressure sensor node, wireless automatic control water doping valve, backbone network gateway, for fear of accidents such as initiation fires, according to relevant laws and regulations, design and authenticate by safety anti-explosive in line with safety requirements.
In the present embodiment, due to the directly outdoor well head that is arranged on of on-the-spot erection unit, bring returning-oil temperature, outside the more direct advantage of watering quantity corresponding relation, also the field work ability of equipment is had higher requirement, the mode of installing in order to adapt to the present embodiment well head, in field apparatus design process, all consider wide temperature working range (40 to+85 degrees Celsius), the above degree of protection of IP65, and consider anti-lightning, requirement such as antitheft field extreme environment such as grade.
From above-mentioned, water-mixing tracing heat control system of the present invention, by wireless sensor node being set on the corresponding return line of oil well, gather pipeline returning-oil temperature information, water mixing pressure information and return pressure information, and export water mixing companion thermal control node to by wireless network, water mixing companion thermal control node is according to the information receiving and pre-stored watering quantity expert database, obtain the watering quantity difference of the watering quantity that watering quantity that best returning-oil temperature is corresponding is corresponding with current returning-oil temperature, be scaled valve opening angle information, and export water doping valve node to, thereby regulate the valve opening angle of water doping valve node, to control the returning-oil temperature of getting back to metering room in the temperature range setting in advance, thereby realize low temperature crude oil transmission in the most energy-conservation mode.Like this, in oil field water mixing companion thermal recovery oil production technology, wireless sensor node can Real-time Obtaining temperature and pressure information, without manual inspection, can grasp in time single oil well production multidate information, reaction speed is fast, operating efficiency is high, the low level management pattern that manual inspection is regulated upgrades to meticulous closed loop automatic control mode, thereby it is defeated to realize safe and reliable low temperature collection, not only greatly reduces the loss of heat energy, and the energy consumption of minimizing water, electricity, gas, realize energy-saving and emission-reduction; Further, can be poor according to returning-oil temperature, water mixing pressure and return pressure, the opening angle state of automatic control and adjustment water doping valve, watering quantity can be realized real-time adjustment, by controlling watering quantity, returning-oil temperature is controlled to optimum state, manage meticulously, effectively reduce energy resource consumption; And water mixing companion thermal control node is coordinated, unified to control each oil well, temperature, the pressure oscillation of oil well are little, have improved informationization, the automatization level in crude output and oil field, have significantly reduced the labour intensity of oil extraction operation; In addition, due to adopt controlled in wireless, thereby can not affect production, invest little, the implementation cycle is shorter.
The foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
