Problems solved by technology

[0003] The water content of the oil field is high, and the contradiction of inhomogeneity in the depth of the reservoir continues to deepen. The on-site construction of profile control and water plugging operations, and the preparation of profile control agents are all done manually. High cost, low work efficiency, inaccurate dosing often occurs, the dosing time interval and dosage cannot be guaranteed, and the non-standard dosing method leads to frequent failures of stirring motors, reducers, profile control pumps and other equipment , which directly affects the effect of water plugging and profile control operations
