Cabled Intelligent Water Injection Solution

（1）Each water injection layer is equipped with a cabled intelligent injection regulator, and separated by a cable through packer;

（2）The surface control unit can long-term monitor down hole flow, temperature, water injection pressure and formation pressure, and obtain the total amount of injected water in each layer in real time;

（3）Real-time monitoring of the water injection volume of each layer, real-time regulation of the valve opening, and control of the water injection volume within the allowable error;

（4）It can communicate with the remote control room, realize the real-time detection or reset of the water injection volume of each layer, check the pressure and temperature of the water injection layer, and check the sealing performance of the packer；

（5）The wellhead intelligent calibration self-tester instrument can periodically re-calibrate and calibrate the parameters of the down hole water injection regulator;

（6）The number of water injection stages is not limited.Suitable for vertical well, highly deviated well and deep well.

Cableless Intelligent Water Injection Solution

（1）The cableless intelligent water injection system realizes two-way communication between the surface and the down hole through the pressure and flow carrier technology without the requirement of cable operation, low investment, and is the real wireless transmission；

（2）The dual detection method of pressure and flow carrier improves the accuracy and timeliness of decoding, greatly reduces the bit error rate, and effectively improves the reliability of wave code communication；

（3）Through the remote monitoring platform, he can monitor the down hole layered flow, layered water injection pressure, formation pressure, temperature and other parameters of the water injection well in real time；

（4）It can realize the coordinated communication and control of the down hole, ground and base, and realize the layered measurement and adjustment of water injection wells, well management and dynamic monitoring without the need of other supporting equipment and personnel；

（5）Low power consumption, 3-year power consumption is less than 60% of the total battery power；

（6）There is no need of down hole cable operation,  the risk of completion work is low；

（7）It is suitable for vertical well, highly deviated well and horizontal well with few injection stages and shallow well depth；

（8）When the number of water injection layers is large and the permeability coefficient is not uniform, it is difficult to regulate the cableless intelligent water injection regulator.
