Problems solved by technology

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 channel of water flow is formed in the formation, resulting in water cones. , water channeling, water ridges and other problems have seriously affected the oil production of oil wells, and the water control tools used in the existing horizontal well oil production have many deficiencies in the actual use process, which can only delay the formation of water cones, but cannot completely eliminate them.

Abstract

The invention discloses an oil stabilizing and water control valve. The oil stabilizing and water control valve comprises a valve body. The valve body is provided with a first liquid port and a second liquid port. A plurality of annular runners are formed in the valve body and sequentially arranged in a nested manner from interior to exterior, and the adjacent annular runners communicate. The first liquid port communicates with the annular runner on the outermost side, and the second liquid port communicates with the annular runner on the innermost side. In the using process of the provided oil stabilizing and water control valve, stratum crude oil and stratum water enter the oil stabilizing and water control valve, due to the fact that the stratum crude oil and the stratum water are different in viscosity and density, generated centrifugal force is different, the stratum crude oil flows in the circumferential direction, the stratum water flows in the radial direction, automatic distinguishing of the crude oil and the water is achieved, the excess flow of the stratum crude oil is large, and the excess flow of the stratum water is low.

Description

technical field [0001] This article involves but is not limited to petroleum engineering technology, especially a valve for stabilizing oil and controlling water. Background technique [0002] Stabilizing oil and controlling water is the only way to control the cost of oil and gas production and improve the benefits of oilfield development. There are many ways to control water, and the most common way 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. 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 channel of water flow is formed in the ...
