Downhole electronically controlled water plugging and production increase switch

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 oil field downhole tools, and in particular relates to a downhole electronically controlled water plugging and production increasing switch. Background technique [0002] After the oil field enters the stage of high water-cut production, it is often necessary to take water blocking measures for the high aquifer, exploit the low aquifer, and seal the high aquifer, so as to achieve the purpose of stabilizing oil, controlling water, increasing production and reducing consumption. The traditional water shutoff process adopts the mechanical water shutoff method, which has complex process, long construction period, inflexible adjustment of water shutoff, and automatic control cannot be realized, so the economic benefit is poor. In order to make up for the shortcomings of the traditional mechanical water shutoff process, researchers have developed electric water shutoff tools, such as an underground wireless pre...

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
