The invention discloses a well selection method and system for ultra-low permeability reservoir water injection well updating, and belongs to the technical field of oilfield development. The well selection method comprises the following steps that a target oil reservoir water injection well updating potential evaluation system is established; obtaining index parameters in the target oil reservoir water injection well update potential evaluation system corresponding to the target oil reservoir water injection well update candidate well, and normalizing the index parameters; and determining a potential comprehensive evaluation index of the updated to-be-selected well of each water injection well of the target oil reservoir, and determining a planned implementation well according to descending order arrangement. The method can solve the problems of low manual well selection efficiency, high individual subjectivity and large result difference at present, and ensures the implementation effect of updating of the water injection well.

This application relates to the field of oilfield development technology, and particularly to an oil production equipment and method. The oil production equipment includes a support base, packers, a water injection oil production assembly, and a controller. The support base is connected to the water injection oil production assembly. Multiple water injection oil production assemblies are arranged sequentially along the height direction and connected to each other. Each water injection oil production assembly has an oil inlet and a water outlet. The oil inlet allows crude oil from the outside to enter, and the water outlet supplies water to leave the water injection oil production assembly and inject it into the oil layer. Multiple packers are also present, with two adjacent packers forming a flow cavity with one water injection oil production assembly. The oil inlet and water outlet of each water injection oil production assembly are connected to the same flow cavity, and adjacent flow cavities are relatively sealed. The controller controls the opening and closing of the oil inlet and the water outlet. The oil production equipment of this application can improve the oil production efficiency.
