Water injection exploitation refers to the injection of water into the reservoir through special injection wells during the development of the oilfield to maintain or restore the pressure of the reservoir, so that the reservoir has a strong driving force to increase the rate of exploitation and recovery of the reservoir.

Loose sandstone and long-term water flooding oil wells will cause a large amount of sand production in oil wells. In order to prevent sand production, on the one hand, correctly choose cementing and completion methods according to oil layer and oil well conditions, then make reasonable production measures and control production pressure difference; On the other hand, according to the requirements of the oil layer and the production process, the corresponding sand control technology is adopted to ensure the normal production of the oil well.

Because some solids are difficult to dissolve in water, when one or more of these solids exist in a large amount in the aqueous solution, under the agitation of hydraulic or external power, these solids can exist in the water in an emulsified state to form an emulsion. Oil-water mixtures and water-oil mixtures will form a relatively stable water-in-oil or oil-in-water structure in these two phases. The theoretical basis is "electric double layer structure". In this case, add some medicament to destroy the stable electric double layer structure and stabilize the emulsified system, so as to achieve the purpose of two-phase separation. This kind of technology is called crude oil demulsification technology, and these agents for destroying emulsification are called demulsifiers.

In mud pump drilling work, mud is often used as drilling fluid. They are abrasive and flow under high pressure, so certain parts of the water pump are worn out. In order to prolong the service life of the wearing parts of the mud pump, it is necessary to analyze the damage process and causes of the wearing parts of the mud pump, and take effective measures to improve the comprehensive benefits of the drilling work.
