Abstract
A method of blocking a water out zone in a production well includes the steps of connecting a throttle unit to a dump bailer, wherein the throttle unit is internally defined a flowing space, which can be adjusted in size to thereby control a flow rate of cement for blocking the water out zone; loading the cement into the dump bailer; slowly lowering down the loaded dump bailer to the water out zone in the production well; opening an outlet of the dump bailer under control, so that the cement flows from the dump bailer into the throttle unit and is released at a flow rate preset by adjusting the size of the flowing space; allowing the released cement to load up in the water out zone and slowly permeate into a gravel layer in the production well before becoming cured to block the water out zone.
