Modular flow adjustment device

Abstract

The invention relates to the technical field of oil exploration, belongs to oil exploration wellhead produced liquid flow control equipment, and particularly relates to a device capable of adjusting flow in a modularized mode. Through holes axially penetrating through end faces of two ends of a cylindrical module base body are uniformly distributed in the circumferential faces of end faces of the cylindrical module base body, module bodies are fixedly arranged in the through holes, the diameters of an inlet channel and an outlet channel at two ends of each module body are different, a ball valve is arranged between the inlet channel and the outlet channel at two ends in each module body, and a rotary shaft of each ball valve penetrates out of a cylindrical face of the module base body. The module bodies are installed in the uniformly distributed through holes in the end face of the module base body, the rotary shafts of the ball valves of the module bodies penetrate out of the cylindrical face of the module base body in a center radial mode, and the outer cylindrical faces of two ends of the module base body are respectively provided with connection threads. According to the device, on the condition that shut-down operation is needless, the hole diameter of an oil nozzle is conveniently adjusted, adjustment of the hole diameter is achieved through conversion of the module corresponding to the hole diameter, the modules are mutually independent and are not mutually influenced, operation is flexible, performance is reliable, utilization is convenient, each module can be independently replaced, and utilization cost can be reduced.

Description

Technical field [0001] The invention relates to the technical field of oil exploitation, and belongs to a production fluid flow control device at the head of an oil production well, in particular to a modularized flow adjustment device. Background technique [0002] At present, in the process of oil production, in order to control the production pressure difference at the wellhead of the oil production and achieve the purpose of throttling and releasing injection for production, fixed nozzle sleeves are often used. The external thread of the nozzle and the internal thread of the nozzle sleeve are matched and connected, and different current limiting requirements can be achieved by replacing nozzles with different specifications and apertures. When the fixed nozzle diameter needs to be changed for steam injection or transfer pumping, the only option is to shut down the well, remove the nozzle cover and replace the fixed nozzle after decompression. [0003] In summary, the installa...
