Description
Technical field
The present invention relates to a kind of water injection well and control checkout equipment, especially a kind of water injection well intelligent flow supervising device.
Background technology
In the petroleum resources exploitation later stage, due to the decline of strata pressure, often take water flooding regime to supplement oil field energy.The object of oil-field flooding is in order to keep oil field energy, keeps formation pressure, improves fluid supply capacity, reduces crude oil lapse rate, to reach the object of further recover petroleum, is the important means that realizes crude oil high yield, stable yields.Particularly oil field enters the tail period stage, and worse and worse, stable yields difficulty increases various increasing oil measure effects day by day, and strengthening effective water filling is the key of improving at present Development Response of Oilfield.
For keeping strata pressure, need continue to increase water injection rate.The stable yields that the quality of water filling situation is directly connected to oil field whether, if water filling is unstable, can cause the water logging of sudden and violent property, and oil-bearing stratum flooding involves imbalance, and water drive development degree is low.Owing to being subject to the impact of the factors such as the variation of oil field well geological condition and well-flushing, insufficient water, the injection allocation amount of flood pattern is different in difference exploitation period, and water injection rate, with the variation of Exploitation Status, need to often be adjusted.
When oil well pressure changes, water injection rate will change thereupon, and at present a lot of flushing amounts are mainly Artificial Control.Every mouthful of water injection well is all provided with high pressure valve, pressure meter, high-pressure water-filling meter.Water filling valve used mostly is high pressure sluice valve or stop valve, needs artificial rotation hand wheel during switch, is used for opening or closing valve.Operating personnel carry out manual adjustment according to water injection technology injection allocation amount, because gate valve or stop valve are unsuitable for regular adjusting, screw mandrel and nut wearing and tearing leakiness, due to manually operated time lag of effect, the abnormal conditions that can not occur water filling be processed in time in addition, night particularly, due to pressure oscillation, operating personnel can not find in time and handle it, and out of control or counter the telling of water injection rate " poured in down a chimney ", when serious, cause formation sand production, have a strong impact on stable exploitation and the safety in production in oil field.For the cycle short between the outstanding or large oil well of difficulty of test of water injection well and interlayer contradiction, manual testing's control accuracy is poor, water injection rate regulates difficulty large, workload is large, water filling is flow backwards and the formation sand production phenomenon that therefore causes happens occasionally.On the other hand, most of oil field water injection pressure all, between 10～40MPa, belongs to high pressure hazardous environment, and common gate valve or stop valve rapid wear leakiness, exist many unsafe factors in practice, and on-the-spot manual adjustment is dangerous.In addition, injection flow manual adjustment, program is loaded down with trivial details.
Summary of the invention
The object of the invention is to, provide a kind of monitoring convenience, saving personnel, monitoring to regulate in time accurate water injection well intelligent flow supervising device.
The present invention solves the technical scheme that further technical problem adopts: a kind of water injection well intelligent flow supervising device, comprise Surveillance center, data collecting system, data collecting system comprises GPS communication module, data acquisition module, data acquisition module comprises single-chip microcomputer, flow meter, valve body control module, GPS communication module, flow meter, valve body control module are connected with single-chip microcomputer respectively, and GPS communication module and Surveillance center carry out long-range wireless telecommunications.
This arranges and utilizes flow meter to monitor oil-field flooding well yield, and real-time detected value is sent to single-chip microcomputer, single-chip microcomputer passes through the unlatching of valve body control module by-pass valve control according to the parameter arranging in advance, utilize fuzzy control technology control valve state, thereby realize the adjusting of water injection rate, also utilize and realize the remote monitoring that GPS wireless communication networks and computer networking technology realize water injection well in oil fields being connected between Surveillance center and GPS communication module, the data that gather are utilized GPS communication module, data are sent to Surveillance center, staff needn't arrive on-the-spot getting final product in time like this, obtain exactly field working conditions information, in addition, the duty of judgment device at any time, find in time fault, reduced to greatest extent the loss being brought by accident.
The further setting of the present invention is: valve body control module comprises motor, control valve, and the output of motor is connected with the input of control valve, and motor is connected with single-chip microcomputer.
This arranges valve body control module and adopts motor and control valve to realize, in order to keep valve opening position to avoid rotating frequently to control, switch, and the imbalance of electric operator inertia and vibration, utilize Fuzzy Adaptive PID Control to realize the operation to valve.
The further setting of the present invention is: also comprise sensor, modulate circuit, the output of sensor is connected with the input of modulate circuit, and regulating circuit is connected with single-chip microcomputer.
This is arranged on and on single-chip microcomputer, is provided with sensor, situation more complicated due to Oil Field, various environmental factors are a lot, in order to accomplish more fully to monitor, be provided with sensor, sensor and flow meter coordinate can gather more data, such as a lot of data such as temperature, pressure, flow, make applicability of the present invention wider, monitoring and control are more comprehensive, safety.
The further setting of the present invention is: also comprise sun-generated electric power, sun-generated electric power is connected with single-chip microcomputer.
What this arranged employing is sun-generated electric power, consider that most of oil field is located in an outlying district, the problems such as oil well dispersion, also have when external power grid introducing difficulty, when economical unreasonable, the power supply system that independently generates electricity should be set up in oil field, so the present invention adopts sun-generated electric power, not only power supply is convenient, and independence, energy-saving and environmental protection.
The further setting of the present invention is: also comprise water injection control system, single-chip microcomputer is connected with motor, and motor is connected with control valve, and control valve is connected with flow meter respectively with single-chip microcomputer, forms water injection control system.
This setting is provided with water injection control system, this is one and is comprised of four basic links, there is an output from system to single backhaul traffic control system of the backfeed loop formation of input, find out by experiment the response speed of the closed-loop system forming between flow measurement and controlling unit, in mcu programming in conjunction with these parameters, thereof using PID algorithm is realized actual flow signal and is relatively shown that with setting instantaneous delivery " deviation " varies in size, to YE (motor), send " switch " command pulse time length different, realize YE (motor) quick, adjust flux controlling valve is realized and is stablized accurate water filling reposefully, reach and control accurate object.
