By making examination of the effect,the system of infusion and dust-proofing,and its monitoring and controlling,the practice illustrates that this r.

This paper, through discussing of the static and dynamic wettability of water and surfactant water solution on coal, put forward the importance of surfactant in dust control by water infusion and put forward the principle and optimum concentration, demonstrated the neccessity of flooding in advance.

Study on anti-corrosion and anti-scaling technology of water injection system in Qianda oilfield;

A hydroviscous speed-regulating clutch used in oilfield water injection system;

Energy-saving technology by adjusting input voltage of electromotor in water injection system.;

But the cost to maintain water-injection system takes a large percent in the cost of petroleum development, about 30~40%,therefore it have practical meaning to study the optimum control technique of water-injection system to decrease energy and cost.

Optimization of operation parameters of waterflooding system considering variable frequency speed regulation;

The research is mostly aimed at power saving countermeasure about waterflooding system in theLamadian oil field; waterflooding system; energy consumption of waterflooding; all energy consumption;power saving countermeasure oil field.
