Oil field Intelligent irrigation wireless monitor system
The research purpose of Pipeless Intelligent Oilfield water injection Monitoring System

   Oilfield uses high-pressure injection valves mostly, heavy adjustment, time-consuming, and easy blocking valve seat are easily to be blocked, if it is not closed thoroughly, the valve's life will be short. Given artificial conditioning mode, water pressure will fluctuate and the injection of water will be effected. Especially for the night, because of stem pressure fluctuates, the workers can not notice it in time and make adjustment, causing the water going out of control. When the dry-pressed is even lower, it will result in the "encroachment" phenomenon,causing the sand going out and will seriously affecte the stability of oil field development, and because of the high pressure water injection environmental hazards, ordinary valve is easily catching leakage so that the scene of regulation is extremely unsafe.

Theory and principle of Pipeless Intelligent Oilfield water injection Monitoring System

"Double stream" adjusting Valve techonology
   With meticulously research and successful development, the techonology has changed the traditional use of valve regulating causeing most of the adjustment difficulties and valves easily damaged with very short life, which is not suited for regularly the shortcomings of conditioning. We use high-quality special steel double steam rotary flow regulation means, make the controlling more easily, scaling, leakagewhether with positive pressure, and anti-steady flow.

Singlechip Machine controlling technology
   Using intelligent controling PWM outputing steady flow PID closed loop flow control or steady regulation, with acquisition of high precision of pressure, flow and rate transmission. The control is extremely smooth, safe, reliable and realizes automatically 24 hours steady flow control or regulation. Through panels it sets up the starting pressure values for water injection.
   System configuration has standard RS-485 interface, can directly put into on-line transmission networkGSM / GPRS digital interface. From very earlier time, the company has developed a successful online GPRS digital transmission network systems and software in monitoring the implementation in oilfield.
Oilfield water injection intelligent wireless monitoring system - electromechanical integration
   "Double stream" SCM valve technology, and advanced control technology have been developed into one electromechanical integration device successfully which resolve the the problem of insecurity of high pressure water injection oil field manual controling.

Oilfield water injection intelligent wireless monitoring system - SCM control regulation
   The SCM system receives artificially set parameters, and with the deceleration of output position feedback signal and back-end Doulbe stream valve pressure flow sensor output pressure, flow rate feedback signal to make comparison. By PID algorithm, to output the positive and negative motor inversion control signal. By location signal to rotate the motor, reduce transmission torque, double stream valve can be rotated into Valve switch degrees.
Oilfield intelligent wireless monitoring system - the injection "Double stream" regulator valve structure
   Using special quality steel, double stream flaterotary means to control the flow , no matter it is given positive or negative pressure, the control is easy, scaling, leakage and the valve's life is more than five times above the common control valve.


Oilfield water injection intelligent wireless monitoring system - grinding wheel-regulating valve
   Sophisticated and concise design ideas, the key parts "grinding wheel" has selected wear resistance, corrosion resistance and high-quality materials, which can substantially improve the service life. It is simple in structure and rapic operation, good flow conditioning linear and long service life, and other significant advantages.


Oilfield water injection wireless intelligent wireless monitoring system - Automatic Transmission Technology
   To meet the needs of Digital Oilfield, the system configurates standard RS-485 interface, with the GSM / GPRS network interface directly online transmission. From very early on, the company has developed successful online GPRS digital transmission network systems and softwares. Through microcomputer set parameters, on the injection wells, instantaneous flow, pressure, injection of state data, such as on-line automatic tracking, monitoring and controling, it accurately grasp the formation energy changes, timely adjustment of water injection, water injection to achieve precision.


Oilfield intelligent wireless monitoring system - main functions of the system
   1. Realizing the water distribution between the injection wells instantaneous flow, pressure, injection of state computer data, such as on-line automatic tracking, monitoring and control;
2. Entire water distribution system on single well, automatic adjustment can really play the role of water injection to control the flow distribution within the scope of the injection,it can solve the artificial control precision on injection wells monitoring, to avoid heavy work load and other problems;
3. Using SCM technology for electronic control pulse wide band modulation controling, closed-loop steady flow control, pressure flow of high precision flow of the set, automatically 24 hours steady flow control;
4. After top injection or lower pressure on drop or water injection, the installation of the system of water distribution of them will effectively be resolved. Starting set injection pressure, when the dry-pressed is smaller that starting pressure, self-closing "double stream" will be set to prevent pressure on the anti-blocking sand recovering, dry-pressed resumed, the valve will be automatically opened;
5. Effective way to avoid the dangerous incidents under high pressure water injection operation;
6. Achieve injection dynamic curve generation, the output of the print statements, historical data inquiries With the remote computer through the GSM / GPRS communication control
