In order to continue to maintain higher recovery in these high water cut hydrocarbon wells, or to extend the water free or low water production periods in side bottom water reservoirs, water control by physical or chemical means is often required. Compared with chemical water control, physical and mechanical water control has the advantages of low cost, environmental friendliness and long effective period, so that the water control is usually carried out in a physical and mechanical mode at present, and the application degree of the self-adaptive water control valve is the most extensive.
