Flange type fracturing combination manifold device with damping device

Abstract

The invention relates to a well fracturing device, in particular to a flange type fracturing combination manifold device with a damping device. A high pressure manifold pry is in a square frame shape,the high pressure manifold pry and a low pressure manifold are connected through a combination support, the low pressure manifold pry is connected with a low pressure manifold, the high pressure manifold pry and the high pressure manifold are connected through a bolt type four way joint and a fixing support connected with the bolt type four way joint, a fracturing head is connected to the front end of the bolt type four way joint, the bottom of the damping device is connected with the high pressure manifold pry, the upper portion of the damping device is connected with the bolt type four wayjoint, four hydraulic jack supports are connected with the two ends of the side faces of the high pressure manifold pry, and hydraulic jacks are arranged on the hydraulic jack supports. High and low pressure fracturing solutions are conveyed to a well mouth and a fracturing truck respectively, vibration of the fracturing vehicle and impact caused by vibration on a high pressure component in the manifold can be sufficiently absorbed.

Description

technical field [0001] The present invention relates to fracturing equipment. Background technique [0002] At present, the fracturing development of oil and gas wells generally adopts a more advanced and efficient well factory mode. Due to the large displacement and high pressure of this fracturing mode, the pulsation of the fracturing pump on the fracturing vehicle is aggravated, and the continuous strong pulsation of the fracturing pump is transmitted to the fracturing pump. When the combined manifold is cracked, the vibration of the manifold components, especially the high-pressure components, will intensify. The high-volume fracturing fluid will intensify the erosion of the inner wall of the high-pressure components due to the excessive flow rate, which will lead to the failure of the high-pressure components. The connection between the combined fracturing manifolds is densely packed with pipelines, and the friction between the low-pressure hose and the high-pressure pi...

[0002] At present, the fracturing development of oil and gas wells generally adopts a more advanced and efficient well factory mode. Due to the large displacement and high pressure of this fracturing mode, the pulsation of the fracturing pump on the fracturing vehicle is aggravated, and the continuous strong pulsation of the fracturing pump is transmitted to the fracturing pump. The vibration of the manifold components, especially the high-pressure components, will be aggravated when the combined manifold is cracked, and the high-volume fracturing fluid will intensify the erosion of the inner wall of the high-pressure components due to the excessive flow rate, which will lead to the failure of the high-pressure components.

The connection between the fracturing manifolds is densely packed, and the friction between the low-pressure hose and the high-pressure pipeline increases during vibration, which makes the high-low pressure pipeline more likely to fail
