Abstract

The invention provides a water regulator, a determination method of a water nozzle of the water regulator, and a water injection tubing string. The water regulator includes a first barrel having a water outlet hole; a second barrel having a water inlet hole, wherein the second barrel is connected to the first barrel, and one end of the second barrel extends into the first barrel; a communication portion, wherein one end of the communication portion is arranged on the first barrel and communicates with the second barrel, and the other end of the communication portion communicates with the water outlet hole; a water feeding portion which is connected to one end positioned in the first barrel, of the second barrel, wherein the water feeding portion communicates with the water outlet hole through the second barrel and the communication portion so as to form a first water injection flow path; and a water discharging portion which is connected to one end away from the water feeding portion, of the second barrel, wherein an inner chamber of the first barrel communicates with the water discharging portion through the water inlet hole so as to form a second water injection flow path separated from the first water injection flow path. The problem that the measuring and regulating efficiency of a water injection well is low in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of downhole water injection and measurement and adjustment in an oil field, in particular to a water distributor, a method for determining a water nozzle of the water distributor, and a water injection pipe string. Background technique [0002] 1. Current status of water nozzle measurement and adjustment technology: oilfield water injection has lasted for decades, and the water injection method has experienced general water injection and layered water injection. Layered water injection has gone through: hollow water distribution → integrated concentric → eccentric water distribution → bridge eccentric water distribution → integrated measurement and adjustment (hollow integrated measurement and adjustment, eccentric integrated measurement and adjustment). Although it has been going on for decades, the selection of water nozzles has always restricted the quality and efficiency of water injection well testing and adjustm...
