Underground electric control water plugging production increasing switching device

Abstract

The invention discloses an underground electric control water plugging production increasing switching device, and relates to the technical field of oil field underground tools. An upper connector, anouter barrel, a lower connector, a center pipe, a power module, a motor and a valve mechanism are included. The end, connected with the outer barrel, of the lower connector is provided with a gear groove. A combined shaft hole is formed in the groove bottom of the gear groove. The gear groove is internally provided with a gear. The center line of the gear is perpendicular to the center line of the outer barrel. The center of one side of the gear is provided with a shaft end in a protruding manner. The shaft end is inserted in the combined shaft hole. A wrench hole in which a six-ridge wrenchis inserted is formed in the center of the other side of the gear. A tooth disc engaged with the gear is machined at the lower end of the outer barrel. The combined shaft hole at least comprises two shaft holes in which the shaft end is inserted, the shaft holes are arranged along the straight line at equal intervals, and every two adjacent shaft holes are overlapped. Through the underground electric control water plugging production increasing switching device, an electric water plugging tool can be directly maintained in the well site and does not need to be transported back to a workshop, and the construction efficiency is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of downhole tools in oil fields, and in particular relates to a downhole electronically controlled water blocking switch for increasing production. Background technique [0002] After the oilfield enters the high water cut period, it is often necessary to take water plugging measures for high water cut layers, exploit low water cut layers, and plug high water cut layers to achieve the purpose of stabilizing oil and water, increasing production and reducing consumption. The traditional water shutoff technology uses mechanical water shutoff. This water shutoff method is complicated in process, long construction period, inflexible water shutoff adjustment, and can not realize automatic control, so the economic benefits are poor. In order to make up for the shortcomings of traditional mechanical water shutoff technology, researchers have developed electric water shutoff tools, such as a downhole wireless pressure mea...

AI Technical Summary

Problems solved by technology

However, due to the large size, large diameter, and heavy weight of the electric water plugging tool, and the disassembly of the threaded connection is laborious, a large vise and pipe wrench are required for disassembly and assembly, and the well site usually does not have the conditions for disassembly and maintenance of the electric water plugging tool. Transported back to the workshop for maintenance, causing a relatively large adverse impact on the progress of the work
