Composite channel water control valve

Abstract

The invention discloses a water control valve for a compound channel. The water control valve comprises a valve body, wherein a spiral channel is arranged in the valve body, an inlet communicating tothe outer side of the valve body is formed in the edge area of the spiral channel, and an outlet penetrating through the bottom of the valve body is formed in the central area of the spiral channel; and a plunger moving along the outlet axis direction is also arranged in the valve body, the lower surface of the plunger faces the outlet, and the upper surface of the plunger faces a through hole penetrating through the top of the valve body.

Description

technical field [0001] The application relates to but not limited to the technical field of petroleum exploration, especially a composite channel water control valve. Background technique [0002] In the prior art, stabilizing oil and controlling water is the only way to control the cost of oil and gas production and improve the benefit of oil field development. There are many ways to control water. At present, the more commonly used method is to use water control tools to control water. In today's oil and gas industry, there are more and more horizontal wells and highly deviated wells, especially in the field of offshore oil, where the number of horizontal wells and highly deviated wells accounts for the majority. [0003] Among them, during the production process of horizontal wells, due to the different suction pressures on the various formations in the horizontal section, the heterogeneity of the primary and secondary formations, the difference in fluid mobility and oth...

AI Technical Summary

Problems solved by technology

[0003] Among them, during the production process of horizontal wells, due to the different suction pressures on the various formations in the horizontal section, the heterogeneity of the primary and secondary formations, the difference in fluid mobility and other reasons, a dominant flow channel for water flow is formed in the formation, resulting in water Phenomenon of cone, water channeling, and water ridge intrusion have seriously affected the oil production of oil wells

[0004] However, the existing water control tools used in horizontal well production have many deficiencies in the actual use process. They can only delay the formation of water cones, but cannot completely eliminate them.
